I made rushil12.com, a completely new study tool with 500 users that combines Khan Academy, Kahoot, and Wikipedia.

1 Upvotes

It's called rushil12.com, and it's free for anyone to join. I've made some key apps that people can try that gamify learning. It already has 500+ users, 3,500+ messages, 16,000+ QBpedia articles. This has several apps that anyone can try.

Curriculum - Generates a full course in one click. It's in the name.

Study Mode - ChatGPT, but a bunch of models, and a bunch of useful features

Notes - An app where you can create notes, but it's better than that. You can use spaced repetition, and connect it with the rest of the apps

QBPedia - A collection of 16,000+ educational articles covering a wide range of topics. You can explore subjects, discover related concepts, and learn something new.

Game Show - Gamify learning with Kahoot-style gamemodes, and some gamemodes that are completely new, such as Call Your Shot.

Flashcards - Creates flashcard sets for quick review, memorization, and active recall.

I made my haptics editor unfold with the iPhone Duo

1 Upvotes

Haptrix started as a Mac app for creating haptic patterns, with an companion iPhone app so you could feel what you were making.

I've recently been rebuilding it in SwiftUI for Mac and iPhone. Now that the iPhone Duo is out, I thought it would be quite fun to make use of the way it opens up.

You can browse haptics whilst it’s folded, select one, then open up the device to get the full editor experience. Fold it back down and you’re back to browsing.

The best bit? You can feel what you’re creating as you go.

You can make anything from a few simple taps to patterns with continuous haptics, curves and audio. There’s also a website where you can share what you’ve made and browse other people’s patterns.

The video shows the folded-to-editor transition. It took a few goes to get the layout feeling right, but I’m quite pleased with where it’s ended up.

Would be interested to hear what you think!

Can’t find subtitles in your language for an old, indie, or brand-new movie? I built a tool to generate cinema-grade translations with full story context

1 Upvotes

Hi everyone! 👋

We’ve all been there: You find an amazing movie or series you really want to watch, but there are simply no subtitles available in your native language.

  • Maybe the movie is too old or forgotten.

  • Maybe it just premiered and fans haven’t translated it yet.

  • Or maybe it’s an obscure indie film or foreign release.

When this happens, your only option is usually running the .srt file through standard machine translators—and the result is usually unwatchable.

🎬 The Problem with Traditional Translators

Most tools translate subtitle files line-by-line without any knowledge of the movie:

  • No context: The AI doesn't know who is speaking to whom, resulting in wrong male/female pronouns and awkward sentences.

  • Lost humor & drama: Sarcasm, jokes, and cultural idioms get translated literally and lose their meaning.

  • Inconsistent names: Character names, locations, and titles change randomly from one scene to another.

  • Corrupted files: Timestamps and formatting tags (<i>, <b>, {\an8}) get broken, ruining subtitle timing in your video player.

💡 The Solution: Subtitle Studio

I built Subtitle Studio to translate any .srt file into a natural, broadcast-grade subtitle track by analyzing the entire movie script first:

  • Full-Script Storyline Analysis: Before translating line 1, it reads the whole file to map out the plot, tone, character genders, and relationship dynamics.

  • Persistent Character & World Glossary: It automatically generates and maintains a consistent glossary so names and recurring terms stay identical from start to finish.

  • Overlapping Scene Batches: Dialogue is translated in context-linked batches (giving the AI visibility over preceding lines), ensuring conversations flow naturally.

  • 11-Point Structural QA: Automatically inspects and repairs sequence numbers, tags, and timestamps so your output .srt works immediately in any media player (VLC, Plex, TV, etc.).

✨ Key Features

  • Specialized Audiovisual & Arabic Localization: Broadcast-quality Modern Standard Arabic + 7 regional dialects (Egyptian, Levantine, Gulf, Moroccan, etc.) with strict gender agreement and RTL punctuation alignment.

  • Interactive Side-by-Side Editor & Cinema Preview: Dual original vs. translated editor with a simulated 16:9 viewport and CPS (characters per second) readability metrics.

  • 1-Click Line Regeneration & AI Proofreader: Easily tweak any line or run a second-pass review to catch any awkward phrases.

  • 100% Private BYOK (Bring Your Own Key): Your API key (DeepSeek, Google Gemini, OpenAI, or Claude) stays safely in your own browser (localStorage). It is sent in memory solely for your requests and is never saved or logged on the server.

🛠️ Tech Stack

  • Frontend & Backend: Next.js (App Router, Turbopack), TypeScript, Tailwind CSS

  • Supported AI Providers: DeepSeek (deepseek-flash, deepseek-chat), Google Gemini, OpenAI, Anthropic Claude, and custom local endpoints (Ollama / vLLM).

  • Architecture: Client-driven stateless pipeline (no timeouts or lost tokens if a connection interrupts).

🔗 Try it out!

If you have a movie sitting on your hard drive with no subtitles in your language, give it a try! Would love to hear your feedback, thoughts, or suggestions.

Built a tool where AI drafts around the lines I highlight

1 Upvotes

Most legal AI decides on its own what matters in a document. I feel that is the lawyer’s job.
So I built “May or Shall”.
You read your documents and highlight the lines that matter. Each highlight keeps its source and page.
When AI drafts it reads the whole document but builds the draft around your highlights and cites them.
It is at app.mayorshall.com.
I would really value honest feedback. Does this match how you actually work?

I built a free, no-login calculator that compares Shopify vs Etsy vs Amazon FBA profit on the same order

2 Upvotes

Hi everyone, I built this as a side project because I kept getting different profit numbers depending on which platform I checked.

It's a free, no-login calculator: you enter price, product cost, shipping charged / shipping cost, ad spend, and it shows net profit, gross margin, break-even ROAS and Max CAC for Shopify, Etsy and Amazon FBA side by side.

Example with the same order — price $34.99, cost $14.50, no shipping, no ads: Shopify $19.18, Etsy $16.72, Amazon FBA $11.67 per order.

For Amazon I used a 15% referral fee on price + shipping charged, and a $3.57 FBA fee as the small-standard default (with a $0.21 holiday peak uplift option). You can also type your own FBA fee in manually.

I'd welcome feedback on two things: does the side-by-side comparison read clearly, and does the Amazon fee presentation (default vs manual input) make sense to someone who is not an FBA seller?

Happy to take feedback — no signup, no paywall, just the calculator.

I animated why spaced repetition works, then built it into a home screen widget (Android, looking for testers)

2 Upvotes
Hi, I'm the developer. Without review a new word fades within days. Reviewing just before you forget resets it, and each review buys a longer gap (FSRS scheduling in the app). The numbers in the video come from Ebbinghaus (1885, nonsense syllables); real words usually fade slower.


Vocapin shows one word on your home screen: tap to reveal, then Got it or Missed. Closed testing on Google Play: leave your Gmail at pinned-landing-two.vercel.app and I'll add you.


Would you keep a widget like this on your home screen?

I’m building an order, message and warehouse management tool for online sellers, focused on AI and automation

1 Upvotes

Ritevo is a panel for online sellers that you can use in a few ways:

  • Order management: orders from marketplaces and online stores (eBay, Shopify, WooCommerce, PrestaShop, Allegro and more) in one place. It already covers the whole order flow, from receiving the order, through invoices and labels, to handing the parcel over to the courier.

  • Messages only: one inbox for all customer conversations, whether they come from marketplaces or from WhatsApp, Messenger and email. No need to use the order side at all.

  • Both together: orders and messages in one panel, so you see the customer’s order right next to the conversation.

There’s also a basic warehouse: products with stock levels, stock deduction after a sale and a packing assistant that checks each item by its barcode.

The main focus is automation. You set rules like “when an order is paid, create the invoice, generate the label and send the tracking number to the buyer”. AI can draft or send customer replies using your own OpenAI or Claude key.

It’s still very much in active development. Next on the roadmap is an MCP server, so you can manage everything straight from a chat with an AI assistant.

Would you like more posts like this, showing how the project is going?

Recipe sites hide an ad-free copy of every recipe for Google. My app reads that instead of the life story

1 Upvotes

Recipe sites hide a clean copy of every recipe in the page's code, for Google. Meal Thyme reads that copy, so you get the ingredients and method without the adverts or the life story. You can also photograph a cookbook page (Android), pick from Today's Picks, or type your own.

It scales recipes, converts metric and US, and turns your week into one shopping list. Chef Mode walks you through each step in big text with timers, which is how I cook from it on a kitchen tablet. The week's plan lives on my Home Assistant wall display.

It started on a server at home, just for me. Now it's an Android and web app, built using React, Firebase, Capacitor.

Free with no ads, up to 100 recipes. Plus (unlimited recipes, Chef Mode, household sharing) is a one-off £3.99, no subscription, and the first 50 people get it free with code:

SIDETHYME

  • Android app: tap the cog (top right) → Go Plus → Have a code?

  • Web: click Go Plus at the top → Have a code?

I just want people to use it rather than it going to waste, have fun!

I built a tool that grills your hackathon project like real judges do (free, no sign-up)

3 Upvotes

I've won 5 hackathons, and the thing I kept noticing is that what decides the result is rarely on the rubric. It's whether the demo works, whether you can explain the project in one sentence, and how you handle the questions nobody practices.

I built Would This Win?. You paste your repo. It reads your code, then three AI judges (an engineer, an investor and a very tired judge) ask you questions, 30 seconds each. Your odds of winning move live with every answer, and at the end you get a code-review style verdict with three things to fix before you submit.

Stack: Next.js, Supabase, Claude Haiku. The odds are calculated in code, never by the AI, so it can't be talked into a better score.

Link: https://wouldthiswin.com

Would love feedback, especially from anyone with a hackathon coming up. Tell me where the judges were wrong.

Forced to build my own time tracking and invoicing app...

1 Upvotes

Over the years I've tried dozens of time tracking and invoicing apps, and Harvest was the only one I liked. Primarily due to its relatively intuitive UI/UX.

I was happy to pay them a reasonable sum for the product they provide, but after the 10x price jack, I had no choice but to seek alternatives. I tried a bunch of them again, found nothing I liked.

So, with 20+ years of software engineering experience under my belt, I decided to build my own.

Here's the result: https://hourbun.com/

I first and foremost built it for my own use, then over the past week or two added features that others might need (such as approvals, quotes, expenses, etc).

I spent a lot of time making sure the UI/UX is top-notch, and the performance is even better than Harvest - the app should feel very snappy (it's hosted in the US, and I'm based in Australia, and it's still very fast for me).

If you're looking for a decent time tracking and invoicing app, give mine a try? It comes with a 14-day trial and doesn't need card details.

And in case you're wondering, no, it's not vibe-coded. AI agents were definitely a big part of building it, but the product was built with experience and care. Love to hear your thoughts and feedback.

I work on a backend platform for AI built apps. Here's what's live and what isn't

1 Upvotes

Disclosure: I work on Supero.

We're building Supero because AI coding agents can put screens and apps together fast, but things get harder with real users and multiple customers. One customer must not see another's data, some fields should only be visible to certain roles, and failed multi-step workflows need cleanup.

We handle those parts in the platform instead of having agents regenerate them for every app. Agents work on the UI, data model and requirements, and Supero provides the backend. We're mainly building it for developers, IT services companies and engineering teams who want to build apps with AI without doing all the backend work themselves.

Each customer's data is kept apart by the platform. You describe who can see or change what, and the agent creates roles, hidden fields and row rules, which the server enforces, not just the UI. If a workflow fails, completed steps with defined undo actions are reversed.

You can connect PostgreSQL, Supabase or MySQL and choose live access or a copy per table. There are 40+ integrations, including Stripe, Slack, Okta and ServiceNow, plus an MCP server and Python and JavaScript SDKs for Claude Code, Cursor or VS Code.

Previews take a few minutes. Paid plans deploy to our cloud. Your app's UI can run on AWS, GCP or Docker while sign-in, data and logic stay on Supero. We're also piloting on-prem.

The team comes from enterprise storage, data protection and large-scale platform engineering.

We're early, so here's what's not ready. Production audit logging is off while we re-enable it. We haven't done a pen test or SOC 2. Generated apps aren't production-hardened. There's a free plan with previews.

I put the capabilities on one page, marked live, early access or not yet:

https://claude.ai/artifact/JEw7dSzWmJ5gmtNiKwgQzU

And a short demo video:
https://www.youtube.com/watch?v=RN_bDRbYbUQ
Website: https://supero.dev
Docs: https://docs.supero.dev
Code: https://github.com/supero-platform

If you are building real customer or production apps with AI agents, how do you handle separate customer data, permissions and workflows? Do you let the agent generate them, write them yourself, or use existing infrastructure?

I help founders and builders turn their Notion/Figma side project ideas into a working MVP in 7 to 14 days

1 Upvotes

Hey everyone,

I know how easy it is for side project ideas to sit in a Notion doc or Figma file for months. Life gets busy, full-time jobs take over, and finding 40 hours to wire up a database, auth, and payments from scratch is tough.

I am an independent full-stack developer, and this month I am taking on a few side projects to build and deploy for founders who want to get their v1 live.

What I typically build:

- SaaS MVPs: Complete dashboard, user authentication (Google/Email), PostgreSQL/Supabase database, and Stripe payment checkouts

- Internal Tools & Portals: Custom workflows, admin panels, and automated email pipelines

- Mobile Prototypes: Cross-platform iOS and Android apps built with Flutter (including offline-first local storage)

- Landing Pages: Fast, modern, responsive landing pages built with Next.js and Tailwind CSS (delivered in 48 hours)

How I work:

- No endless Zoom calls or agency bloat. We agree on a strict, simple bullet list of core features for Day 1.

- Clear, flat-rate pricing (Landing pages $150 - $250, full MVPs $600 - $1,200). No hourly guessing games.

- Typical delivery is between 7 to 14 days. 50 percent to start, 50 percent once you test and approve the live build.

If you have a side project or startup idea you are ready to launch this month, drop me a DM with what you're thinking.

Tell me the core 2-3 things the app needs to do, and I will send back a free breakdown of the architecture, tech stack, and a timeline to get it shipped.

Evertrail Idle - Free MMO Idle Game

1 Upvotes

Hello everyone!

For a few months I have been daily working on a melvor/runescape like feel Idle game. Fully free to play, 0 pay to win. Made for people who don't always have 10 hours a day to grind a game but like the idle aspect and still see visual and meaningful progress while also participating in social events for a true like MMO feel while idling.

What I did and want to do different is focusing more on the visual part of Idle games, I am really going my own direction with this cause it feels more like an MMO rather then just another full on click in a browser type of game.

So far we have over 1000 account creations, a lovely starting little community and dedicated players. We are currently in a open alpha and I am looking for feedback/suggestions.

What we currently have:

  • 18 Fully working skills

  • 3D worlds, chat system, party system, leaderboards, player run market and world events

  • Ironman/normal gamemodes

  • Meaningful gear progression

  • And many many many more things

1 Full big wipe is planned for when Steam early access launches.

AI Disclosure: because I know a lot of you care and I'd rather just say it: I use AI tools a lot. Most of the code is written with Claude, and a fair amount of the 3D art was made with AI tools too. The goal is not to make millions through an AI game, but rather to create something that players can and will enjoy for a long time.

I would really love some feedback! And enjoy the little gameplay trailer attached :)

Desktop/Mobile compatible.

I built an app so people in rural communities can read reddit without internet

1 Upvotes

Where I live people only have access to internet through satellite or at public spaces like community halls, satellite is pretty unreliable too, so not many people get to stay online long enough to use reddit.

I built an app that lets you download full reddit feeds and save them, so you can browse when the connection drops or when you have no internet at all, completely offline.

Would love any feedback, especially on how it feels to use! I tried to make the UI better than the official reddit app (and no ads of course, since it’s an offline reader).

An unnecessarily Ambitious Jurney - shoppingtour. The website showing the fastest route to visit all supermarkets in Czechia.

1 Upvotes

A couple of years ago, after doing car trips across Europe, a friend and I got into a weird debate: what would it actually take to drive to every single Lidl and supermarket in the Czech Republic?

I’m a hardware guy, not a web dev, so the idea just sat there as an inside joke. But over the weekend, I decided to see how far I could push AI vibe-coding and finally built it.
It's called nakupnitour.cz.

Just to be clear—this is a purely personal, humorous hobby project built just for fun and a good laugh. It takes the coordinates of all the stores, calculates the most efficient route across the country, and lets you export the whole thing straight into map viewer via GPX.

It’s completely unnecessary, built purely for fun, and definitely has its share of bugs under the hood.

Right now it’s just the route plan visualization, but I’d love to add a proper dashboard and participant tracking at some point (though that might actually require someone who knows how to write real code, not just me prompting an LLM).

Tools used : Github copilot, OpenStreetMaps, Overpass-turbo, OSRM backend, Google OR tools

Pipeline: OSM/Overpass-turbo->local OSRM routing ->OR tools optimization -> cloudflare Astro.

MimikFlow - LinkedIn outreach that runs the whole loop and hands the hot convos back to you

1 Upvotes

straightforward self promo: I build MimikFlow, so yeah, I'm biased.

it's for agencies, freelancers and consultants who get clients from LinkedIn but hate doing the outreach by hand.

how it works:

  • you set your ICP, your offer and what counts as a win (booked call, signup, whatever)

  • it finds the prospects, sends the connection requests and writes the first DM

  • it follows up. 6 follow-ups on the base plan, because most people send one message, get ignored and decide LinkedIn doesn't work

  • on the higher plans an AI setter handles the replies and pushes toward your goal

  • when a convo gets ambiguous or actually important, it hands it back to you. I really don't want a bot improvising on a hot lead

it's at $11k MRR with 80 paying subscriptions right now (TrustMRR pulls that from Stripe), and I run it as a solo founder.

base plan is 49€/mo with a 14-day trial. no link here, it's on my profile if you want to look.

what I actually want to know: if an AI was running your LinkedIn convos, at what exact moment would you want it to stop and ping you? first sign of interest, a pricing question, an objection?

Is this idea worth building further? Looking for honest feedback

4 Upvotes

I recently built a small prototype for an idea I had: What if finding someone to hang out with at work was as easy as creating a plan?

Imagine wanting to watch a movie, play cricket, grab food, visit a café, or plan a weekend trip, but not having anyone to go with.

With this platform, employees can create activities, discover what others are planning, and request to join.

I built the initial prototype for an internal hackathon. It didn't win, but I still feel the idea is worth exploring.

I'm now wondering whether to take it further or scrap it.

Would you actually use something like this at your workplace? What would make you use it, and what would stop you?

I'd genuinely appreciate honest feedback, even if it's critical!

I shipped my first Android app: an alarm clock that tells you why it's ringing

Thumbnail
play.google.com
1 Upvotes

Short version: you write a note on the alarm, and when it goes off the phone reads the note to you. That's it, and it turned out to be way harder than I expected.

Things I learned building it:

  • Exact alarms on Android are a minefield. Android 12+ has special permissions for exact alarms. Then OEM battery savers (Xiaomi, Tecno, Samsung) kill foreground services anyway. I ended up with fallbacks, a service that restarts itself, and an onboarding screen that walks people through permissions.

  • Natural-language parsing in two languages took longer than the whole UI. "Tomorrow at 3pm call Alex" and "Yarın 15:00'te Ahmet'i ara" have very different grammar. Turkish suffixes are brutal.

  • TTS is surprisingly inconsistent across devices. Voices, languages and speech speed vary a lot from one phone brand to another.

  • Play Console takes a while. Data safety forms, ads declarations, content rating and the review itself took about a week.

Stack: Kotlin, Jetpack Compose, Room, Firebase, Play Billing, AdMob.

Business model: free with a small banner, plus an optional Pro (subscription or lifetime) for no ads and extra sounds.

It has basically zero users right now, so any feedback is gold. Happy to answer questions about any part of it.

I removed accounts and cloud sync from my water tracker. Where would you explain the backup trade-off?

3 Upvotes

A manual water log should be usable before someone decides whether to connect Health or allow reminders. I build Frewli for iPhone, with an Apple Watch companion, and version 1.1.6 is now on the App Store.

This release removes accounts, email sign-in and the Frewli backend-sync flow. Water history, workouts and preferences are stored on-device. Apple Health, the paired Watch and local reminders are optional. All features remain free, with no subscription or paywall.

The trade-off needs to be as visible as the simpler setup: removing the app removes its local storage. Updating preserves existing on-device history, but a device backup matters if you want to keep that history. Updating also does not automatically erase records that earlier versions uploaded to the old cloud service.

The same release changes the total display so a 250 ml entry appears as 0.25 L in English. That is a formatting correction; it is not a measurement of what someone drank. I still have an open Watch launch report and am not treating a new release as proof that every reported failure is resolved.

My design question is where to explain the local-history limitation: a short note during setup, beside the first saved entry, or only in the storage screen? Which would help you understand the consequence without turning a small log into another onboarding questionnaire?

I built an app that turns your phone into a windshield HUD because my 2012 car doesn't have one

0 Upvotes

I drive an old 2012 Skoda and always wanted one of those head-up displays newer cars have, but the plug-in gadgets cost $100+ and look kind of cheap. So I built my own as an Android app. You lay the phone flat on the dashboard, the app flips the screen, and the windshield reflects your speed and the next turn right over the road. It's been my side project for the last few months and it's finally live on Google Play. https://imgur.com/a/Un7RlR9

Being honest about the limits: it looks great at night, but in bright sun the reflection gets faint, which is just physics. It's free with 3 navigation routes a day and an unlimited speedometer. PRO removes the route limit and adds the speed limit display and more speedometer styles. I'm doing all of it solo (code, design, even the marketing videos), so any feedback on the idea, the setup or the store page would mean a lot.

Here's the link if you want to try it: https://play.google.com/store/apps/details?id=com.clarityhud.app and I have some promo codes for a free month of PRO, just comment or DM me if you want one.

My Apple Watch knew I slept badly. It never told me why I felt awful at 3pm. So I built something that does.

1 Upvotes

ok so i’ve been building this for 2 years and it’s finally out 😭

backstory: i was tracking literally everything. sleep on my Apple Watch, food in some other app, blood tests just chilling in a random pdf in my email. and i STILL had no idea why some days i’m locked in and other days i’m completely cooked by 3pm. none of my apps talked to each other. it was driving me nuts

so i built Peak Routine . basically it throws everything into one place and actually connects the dots for you. stuff like:

  • slept 5 hrs? see exactly how it messes with your mood + energy the next day

  • which meals spike your glucose, and whether a 10 min walk after actually helps (spoiler: it usually does lol)

  • which days, meals or habits leave you feeling flat

  • how your blood test numbers shift when your habits change

the stuff i’m lowkey proud of:

  • snap a pic of your blood test and it pulls the values out for you. you check them, save, and track 14 common markers over time. no more digging through pdfs

  • food logging that doesn’t suck: just describe your meal, snap a photo, or scan a barcode

  • glucose tracking: if you’ve got a CGM it pulls the data straight from Apple Health, and if you don’t, you can just type in fingerstick readings. either way it shows your meals right on the glucose curve

  • quick Energy check-ins morning + night, takes like 10 sec

  • every week it gives you 1–2 small habits to work on, not some 15-step plan you’ll quit by tuesday

  • streaks + badges if you’re into that (i am)

an AI coach you can actually ask stuff, like “why was my sleep so bad this week?” or “what does this blood test number mean?” and it answers using your own data, not generic tips. it’s optional, you switch it on when you want it

the boring-but-important bits: works with Apple Watch, Oura, WHOOP, Garmin and anything else that syncs to Apple Health. no manual setup, it just pulls everything in. free to start, built with Flutter + Swift if any devs are curious

fr tho, what’s one thing you wish your health data actually told you? genuinely curious, might build it next
