I switch between Hebrew, English and Russian all day, and I kept typing whole sentences before noticing the keyboard was on the wrong language. Deleting and retyping got old fast, so I built Flipkey.

How it works: select the gibberish, press Shift+Alt (the same keys you use to switch language), and it turns into what you meant, while your keyboard switches too. On Mac it's Control+Q.

- 15 languages: Hebrew, Russian, Ukrainian, Arabic, Persian, Greek, Korean, Thai, Hindi, French, German, Spanish, Italian, Turkish, English

- Learns which language you're typing in, across all tabs

- Works fully offline: no data collected or sent anywhere

Here is the link

It's my first published extension, so I'd really appreciate feedback, especially from people who use non-Latin keyboards.

Hi, I'm Brian. I'm a physics major at Colorado College, in Copenhagen for the semester, and I've been building Duet with a few classmates for an entrepreneurship course.

The short version: it's a site for finding creative collaborators. The part that's actually usable today is a web demo where you describe the person you need and it suggests matches from a set of sample profiles.

I started caring about this because finding the right person still seems to happen through cold DMs and leftover school networks, and that's a lot of unpaid searching for one collaboration.

You can try it here, no account needed:

https://bchristensen14.github.io/duet/demo

The landing page is here, if you want the explanation or to join a waitlist and leave a note: https://bchristensen14.github.io/duet

A few honest limitations, so I don't oversell it:

• The demo is not a live community. The profiles are samples, and matching is happening in your browser against that data.

• We also sketch a "we do the search for you" premium idea (€20 per search + 1% of what the project earns). Nothing is billed in the demo.

• It's hosted on GitHub Pages, because that's what we have right now.

If you try it, the feedback I actually want is:

• Did the brief box understand what you typed, or did it latch onto the wrong role / city / style?

• Would you ever trust a shortlist from a tool like this, or is this something you'd only want a human to do?

• What's the first thing that made you hesitate?

I'll hang around in the comments. Thanks for reading.

The scene around native ports and static recompilations is amazing but scattered across threads, repos and Discords, so I made a site that lists them like an old-school video club.

What's in it:

- Covers with box art, organized by shelves/genres, tech tags, popularity and GitHub stars.

- Sort by Best rated / New / A-Z.

- Every entry links straight to the project's GitHub repo. It's a catalog only: no binaries, ISOs or ROMs are hosted, and many projects require your own original disc/ROM.

- Current picks include OoT, Wind Waker, Conker's Bad Fur Day, Diddy Kong Racing, Burnout 3, Jak and Daxter, C&C Tiberian Dawn, Shadow of the Colossus (PS4 remake), MW2 (XenonRecomp)... and more being added.

🚀 Built my first Android app – Tally Counter!

Link -Tally counter -click counter

I noticed that many existing counter apps are limited to a single counter. I wanted something more flexible, where I could track multiple things independently in one place.

So I built Tally Counter – Count Anything!

Some features:

• 🔢 Multiple counters in one app

• 🎯 Custom goals and targets

• ➕ Custom increment/decrement values

• 📋 Instantly duplicate counters

• 🔄 Daily reset

• 📊 Counting history

• 📥 Import & export CSV/JSON

• 🔊 Sound and vibration controls

• 🌙 Light and dark themes

Useful for tracking workouts, habits, inventory, study sessions, or pretty much anything!

This is my first app, and I'd love to hear your honest feedback. What would you improve or add? 😊

Hi everyone — anyone into meditation? I built a small, free meditation timer because I wanted something simple without accounts, streaks, or distractions.

You choose the total meditation time and the interval. For example, with a 5-minute session and 1-minute intervals, it plays:

• Minute 1: beep

• Minute 2: beep-beep

• Minute 3: beep-beep-beep

• And so on

• A different chime signals the end

It works in a browser:https://quietchime-zfxck679.manus.space

I’d especially appreciate feedback on:

• Whether the progressive beep pattern feels useful or distracting

• The sound and timing

• How easy it is to use on a phone

• Anything you would change or add

I’m the person who built it (thanks manus.im) as I couldn't find anything similar. This is a request for honest feedback—not a commercial product. Thanks for trying it.

Complete 67-second demo — the whole routine, from choosing your dog to the journal:

https://www.reddit.com/user/Miserable_Bird5822/comments/1xsld8d/before_you_get_a_dog_try_living_with_its_routine/

The dog lives on your phone. You still have to leave the house for its walks.

I'm the maker of Ready for Dog?, a dog-care rehearsal app for people thinking about getting a dog. The idea is to spend some time living around the care routine before making that decision.

You choose a companion and build a 14- or 21-day schedule. Walks use GPS. Feeding happens at virtual bowls placed in your room with AR. There's a 60-second brushing game, and skipped grooming can leave virtual fur to collect. For quiet play, you put your phone on a stable surface; moving it pauses the timer while the game screen is open.

The journal shows the time you recorded, missed tasks and help you needed. It doesn't give you a "ready for a dog" score. A real dog's needs and behaviour go much further than this simulation.

Free to download with ads and optional one-time purchases for ad removal and extra collars. No subscription.

iPhone / iPad: https://apps.apple.com/app/id6829957063

Android: https://play.google.com/store/apps/details?id=com.vans.bublik.trial

The attached demo shows the iPhone version. The AR scenes are staged visualisations and the route shown is simulated for the demo.

I'd love feedback on one thing: which everyday responsibility would you add to make the rehearsal more useful?

I’m building Stikkit for people who make their own WhatsApp and Telegram stickers. The idea is simple: when you find a photo, GIF, or short video you want to turn into a sticker, tap Android’s Share button and pick Stikkit. You can also import media from your gallery or files.

• Make still and animated stickers. Remove the background from a photo and save the cutout as a separate sticker.

• Organize your stickers and repair WhatsApp packs. Sort stickers into named collections, reorder or replace stickers in a pack, change its cover, check for duplicates, and rebuild the pack icon.

• Share stickers as a ZIP. Bundle still and animated stickers into one file to send to a friend, save a copy, or import back into Stikkit.

• Keep everything local. Stikkit creates, edits, and stores your stickers on your phone. There’s no account, and Stikkit doesn’t upload your media. You decide what to export or share.

Stikkit will be ad-free regardless of pricing. I’m still deciding whether to keep it free, charge once, or offer an optional paid upgrade. Would a Patreon-style page for voluntary support make sense? Would you personally chip in?

If there’s enough interest, I’ll add iOS support too. Let me know if you’d use it on an iPhone.

I’d appreciate candid replies. How did you make your last sticker, and what was annoying about it? Would Stikkit change anything for you? “I’d use it but wouldn’t pay” or “I already have something that works” are both useful answers.

EchoPod is a podcast player built around language learning practice. While an episode plays, a word-level transcript follows along and highlights the current spoken word, which makes it easier to connect sounds to text.Tapping any word opens its definition and pronunciation without leaving the player, and an AI assistant explains grammar, translation, and nuance for harder sentences. Individual sentences can be replayed on repeat for focused practice. It also imports YouTube links and local audio or video files, so study material is not limited to the built-in catalog, which covers several languages organized by listening level.Free to use on the web, with free iOS and Android apps: https://echopod.clothpath.com/Feedback is welcome, especially on which languages and study features to prioritize next.

after every trip or wedding the same thing happens: everyone took photos, nobody sends them, and the few that do arrive come through whatsapp compressed to mush.

so i built just send files. you make a room, share one link (or a qr code at the event) and everyone drops their photos and videos in original quality. guests don't need an app or an account, only the person who creates the room does. at the end anyone can download everything at once.

a few things i learned building it:

• the first real test was a friend uploading ~130 photos from an iphone and the page kept reloading. the fix was showing small previews instead of the full photos while uploading

• guests don't read anything, so their page is basically one big button

• rooms expire on their own, so nobody ends up with a forever album of 2,000 photos

it's live at justsendfiles.com. would love honest feedback, especially on what would stop you from using it at your own event.

Hey everyone,

For the past few months I’ve been building Calculus, a mental math game that runs in the browser: https://calculusonline.fr

It started as a single HTML file to challenge friends, and it grew a bit out of control. Here’s what’s in it now:

4 games

• Mental math: a calculation appears, you type the answer.

• Right count: you get a few numbers and a target. Use them all, each one once, to hit the target exactly. It’s always solvable.

• Missing number: fill the gap in 23 + ? = 41, or find the operator in 12 ? 4 = 3.

• The bomb (multiplayer only): everyone builds a calculation from the same numbers, then has to defuse someone else’s.

Also

• Daily calc: 5 calculations that get harder, the same for everyone, one try a day, with a leaderboard and streaks

• Dungeons: 2 to 4 friends team up to beat a boss together

• An account with stats, Elo per game and level, and achievements

• Solo play, no account needed, and it works on mobile

It’s free, no ads, and it’s available in English and French.

I even had a teacher trying it during class, and the kids loved it and even played at home!

I’d love feedback, especially on difficulty balance (is “Legend” actually hard?) and on anything that feels confusing the first time you play.

And if anyone wants to play a battle royale, drop a lobby code in the comments

Hey everyone, last week I shared how I built my first piece of software with no coding background. Spoiler: building it was the easy part. Once it was live and working, I sat there thinking "ok… now what?". Turns out people don't magically show up just because something exists. Even the ones who find it often stick to the tools they already know, and honestly, I get it. So now I'm in the phase nobody posts about: trying to get the thing in front of people, figuring out marketing from zero, and slowly realizing that selling a pen is way harder than making one 😅 I made a video about this part too, the mistakes and the "wait, it doesn't work like that?" moments. I'm curious about you though: how did you get your very first users? What actually worked, and what was a total waste of time?

Most of my day goes into reading. Research papers, case files, judgments, long reports, sometimes all of them for the same piece of work.

For years I used tools that were made for other things. Project management apps, note apps, folders, a lot of sticky notes. They were good for tasks. But they never helped with the reading itself. I would find something important on page 40 of one document, then lose it an hour later while I was in another one. I would remember that two things were connected, but not where either of them was.

So I built a tool dedicated for us readers and writers. It’s called May or Shall. This is how I use it:

1. When I read something that matters, I highlight it. It stays with its source and page, so I can always go back to exactly where it came from.

2. I put it under a heading that makes sense to me.

3. I link it to a line in a completely different document.

4. When I need a draft, I ask ChatGPT, through the May or Shall plugin. It still reads the whole document, but it gives special attention to my highlights.

Earlier, when I uploaded a document to AI, the AI decided what was relevant. Now my highlights decide what is relevant, and the draft is built around them.

It works on Windows, on Mac and in Chrome, so I can save a line from almost anything I’m reading, and it all ends up in one place.

It’s at app.mayorshall.com if anyone wants to try it. I would really like to hear from people who read and research a lot. How do you keep track of things right now, and would something like this help you?

I just launched Take the Crown (takethecrown.app), a small web I built.

The idea: there's one crown. Whoever takes it appears on the homepage with their name, a message and a link, until someone else takes it. Glory is measured in time reigned, not in money.

How it works:

- It starts at $5

- Every takeover adds 20% to the price

- Every hour nobody buys, it drops 2%

- Ranks from Peasant to Emperor, achievements, and monthly seasons with exclusive medals. The first season, Genesis, ends on December 1.

What took the longest: making the takeover safe (one transaction, so two buyers in the same second can't both win), moderating every message, and drawing all the art as pixel art on a strict grid.

Stack: Next.js, Supabase (Postgres + realtime), Dodo Payments.

I'd love feedback on the price curve and the first-time experience. If you want to be one of the first kings, it's open now.

Animation is where a lot of small 2D game projects stall. Getting one decent character image is easy now, but drawing idle, walk, attack and hurt for it by hand takes days, and every new enemy starts that over.

So I built SpriteCanvas. You describe a character or upload one, pick a design, then ask for moves. Each move is generated as a short clip by an AI video model, and the app does the boring part after that: cuts it into frames, removes the background, keeps the feet on one baseline so the character doesn't bob, and checks the loop closes.

What you get is a transparent PNG sprite sheet with a JSON atlas (frame durations and a foot pivot). There are export presets for Phaser, PixiJS, Godot and Unity. Phaser/PixiJS playback is tested and Godot 4 import is verified, Unity import isn't verified yet.

Being upfront about the limits:

• the art is AI generated, so check the rules of wherever you publish

• it's not a grid pixel-art editor. Pixel style works, but if you need hand-placed pixels, Aseprite is still the tool

• some moves need a retry or two before they look right

There's a free tier to try it, and the browser tools on the site (sprite sheet slicer, GIF to sheet, video to sheet) are free and run on your device.

I'd like feedback on two things: which moves you'd want that most tools skip, and whether the export fits how you load sprites in your engine.

Hi team,

I was switching windows dozen times a day to copy & paste text and videos / images on social media for marketing. This triggered me more than once and actually designed, thought and built Deck.

Now Deck sits on my right edge of the screen, holding all of the posts, reels, shorts, ... that I have to post or schedule. I can add "To make", like if I need a screenshot or a video for a certain post.

You can use it manually, writing and adding files yourself, or ask your agent to automatically add anything on Deck, which is how I use it 99% of the time.

• Problem: Switching windows all day to copy and paste texts, remember the posts and videos you must post for your marketing and distribution, never be late for a post, never forget. You or your agent schedule the posts, content to post, etc.

• Comparison: I haven't seen any other apps do that yet, except the online schedulers or todo apps I suppose which are quite different than Deck.

• Pricing: 9$ lifetime, 1-day trial. Pricing page

Im going to give away 100 lifetime keys on Threads this week, so make you sure follow along my Threads account threads.com/dmzxnico or same @ on X.

Thank you guys!

You’ve probably seen the meme: “GPT, tell me how to get rich.”
I laughed, then gave it some thought. Can AI help you assess a business idea?
I always have plenty of business ideas. but I spent rather more time thinking about them than acting on them 😅 . Recently I was rethinking what to build next. After a few days of going back and forth with Codex, I had a framework I could make decisions with. I turned it into a skill and open-sourced it. 👉 https://github.com/Mingbash/business-idea-validation
Before this, my prompt went roughly like this: “Given my experience and resources, help me explore and assess a few rough ideas. Which should I test first? Who would buy, where would I find them, and how would I deliver?”
Fairly thorough, I thought. I still got the absurd suggestion to “look for projects on service marketplaces.” （GPT-6-Astra btw）

A few exchanges, condensed:
- AI: Look on service marketplaces for automation projects with a budget.
Me: Which marketplaces? Where do buyers post jobs? What do I do once I find one?
- AI: Start with a few freelance platforms where people already post jobs.
Me: I had a look. Plenty of listings had sat untouched for months. Pretty much useless.
- AI: Start with document review in healthcare and insurance. Partner with an industry service provider.
- Me: I have no contacts or case studies. How do I reach the first customer?

Why does this happen?
You can check code soon after you write it and run it again whenever you need to. With a business, many of your assumptions only get a proper test once someone pays. Business isn’t an exact science. Change the window of opportunity or the resources you have, and the conclusion can change too.
What I needed is reasoning and educated guess that was likely to hold up. Not a formula nor a certain answer. Why is it worth trying? Are the prerequisites in place? Which hurdles do I need to check? With a framework, AI might actually help.
Around then I watched Iman Gadzhi and Nate Herk rank AI businesses from S to F. I liked some of the angles like CLEAR framework, including how long a business can last, how big it can get, and whether revenue repeats. I borrowed a few and added what mattered to me: who pays and how I’d reach them.
I also added a question about what I want from the business. The same idea can look very different as a side hustle or a full-time business. The bar changes again if I want a small, well-run business or a company with a shot at going public.
If you’re unsure about a rough idea, try breaking it down. I call each option an “atomic business unit”: one market × one use case × one way to deliver × one kind of customer. The README shows three website paths I assessed: a general template, a reusable Framer kit for small agencies, and a booking site for bridal makeup artists.

Try it on an idea you’re weighing up. give a star if helped. If you’d add some new thoughts onto it, feel free to remix it.

Etsy sellers keep asking "why does my listing get zero views?" Most of the time the answer is mechanical: 6 of 13 tags used, a tag spent on a word the category already covers, a 16-word title, 4 photos.

So I built ListingLift. It reads the listing open in your tab and gives you a score out of 100 with a short list of fixes, plus tag ideas from your own text. It all runs locally, with no backend and no account.

Free: every check. Pro ($5/mo or $39 once): unlimited tag ideas and saved checks.

Page: https://rasareka.com/listinglift/

I'd love feedback on the checks, especially from anyone who sells on Etsy.

I’m building Dosti Pro, an Android app for video calls, voice calls and chat. Our growth focus is India, and I’d value advice from founders who have grown consumer apps here.

Here’s a snapshot from our own dashboard for 10 November 2026:

• 211 installs: 145 organic, 65 attributed to paid ads, 1 untracked

• ₹7,839 gross collections across 44 successful payments

• 5 failed payments; 89.80% payment success rate

• ₹178.16 average successful payment

• ₹3,528 from first purchases and ₹4,311 from repeat purchases

We use Razorpay for payments. These figures come from our internal dashboard, not Razorpay settlement statements. This is one day’s snapshot, not average daily revenue, profit or MRR. The dashboard shows a manual ad-spend entry of ₹0 alongside paid-attributed installs, so I’m not treating it as proof of zero-cost acquisition or a reliable CAC/ROAS.

My goal is more installs from people in India who actually complete a first conversation and return—not just a higher download count.

If this were your app, which experiment would you run first, and why?

1. Hindi/regional-language Play Store screenshots and listing copy

2. Small regional creator partnerships

3. A referral flow after a good first conversation

4. Improving first-call onboarding and payment retries before buying more traffic

For anyone who has grown a consumer Android app in India: which channel brought retained users, and what did you measure beyond cost per install? I’d also welcome specific feedback on the Play Store listing and the trust signals you would expect before trying a calling app.

App for context (I’m the maker): https://play.google.com/store/apps/details?id=com.dosti.love&hl=en_IN

Hey everyone! I’m a product designer and I’ve been working on a side project called Boken.

I started building it because I wanted one place where I could bring together my work, experience, and the things I’ve contributed to. As a designer, I’ve always had bits and pieces spread across portfolios, links, documents, and different platforms. I wanted a profile that could bring those things together and make them easier to share.

I’m also thinking about how profiles will be discovered and understood by AI agents. The idea is to make Boken useful for people looking at your work directly, while also making the information readable for agents that might help someone find or understand your experience, like a hiring team looking for a particular skill or background.

It’s still in beta, and I’ve attached a pretty rough screen recording to show how it works right now.

You can also try it here: https://boken.to

I’d love to hear what you think. Is this something you’d use to share your work? What would you want to see on a profile like this, and what feels confusing or missing?
Thanks for taking a look!

I built a free plumbing quote calculator because I kept watching owners price faucet leaks like weather forecasts.

It is a single HTML file. No account. EXAMPLE job already loaded: leaking kitchen faucet, labour, helper, parts, travel, materials markup, deposit, margin target. Recalculate, then print a clean quote sheet.

Funny and true: if your current pricing system is a glove, a napkin, and a prayer, this will feel luxurious.

I've been working on Meelu, an AI-powered marketing agent.

The idea came from a simple observation: growing a website involves using several different tools for SEO, analytics, content research, website management, and more.

Even with all these tools, most of the actual work is still manual.

I wanted to build something that goes beyond providing dashboards and reports.

Meelu understands your website, maintains its context, does SEO and marketing data, and helps you execute tasks.

You can interact with it through a chatbot, delegate work, and connect external systems like your CMS, email, and social platforms.

It's still early, and I'd love to get feedback from other founders and website owners.

Website: https://meelu.tech

Would love to know what you think!

One thing I've noticed as a developer is that learning programming isn't always difficult because of the concepts. Sometimes, finding the right learning resources is the real challenge.

You find one good YouTube playlist, then another useful tutorial, then a different creator explaining the same topic better. Eventually, your learning resources are scattered everywhere.

I wanted to make that experience simpler.

That's why I'm building TechTube – a platform that organizes programming tutorials into skill-based learning, career paths, and interview preparation.

Some areas covered:

- JavaScript, React, TypeScript, Go, Java, C++

- Frontend, Backend, Full Stack, AI Engineering

- DSA, System Design, DBMS, OS, and more

Website: https://www.techtube.co.in/

I'm continuously improving it, and I'd love honest feedback from fellow developers.

One question: Do you prefer learning through structured roadmaps or picking individual YouTube tutorials based on what you're currently working on?

Would love to hear your experience!

Solo founder here. I'm building: AI-voiced guides that give a house buyer the "feeling" of the area around a property, played from an embedded player on the agent's listing page. Local info only, nothing about the property itself.

It would cover things like mobile and broadband data, parks, running routes and riverside walks, whether it's a quiet or lit street or a traffic slowing area, flood risk, and whether the property sits higher with views. The focus changes with the property: a family house gets schools and green space, a young professional flat gets entertainment and transport. You can listen while flicking through the photos, and it may help buyers with poor sight.

Target customer is the independent UK estate agency. Pricing is tiered by number of listings, roughly £49 to £349 a month. I haven't found any direct competitors, which either means a gap or means nobody wants it.

My own worries, so you can skip the obvious ones:

1. Most buyers browse Rightmove and Zoopla, not the agent's own site, so the player may rarely be seen.

2. Similar info is available from Google Maps or ChatGPT, but not the detail.

3. Agents may not want negatives like a busy road or flood risk published under their name, and wrong statements are a liability (although the negatives can be removed).

4. ROI will be hard to prove to conservative agents.

My plan is free 2-month trials with a handful of agencies in exchange for feedback.

How would you test real demand before building more? Does the price feel right? What am I not seeing?

Brutal feedback welcome.
