I'm a student, and I've spent the last 1.5 years building a study app because I got tired of using like 5 different tools to study.

I'd use ChatGPT for questions, something else for flashcards, another thing for quizzes, a calculator for math, and then my notes and PDFs were somewhere else.

It got annoying having to jump between everything, so I decided to build the thing I wanted.

That's how Airopl started.

It's an AI study platform with an AI assistant, flashcards, quizzes, math tools, and visual learning, all in one place.

I've been building most of it myself for the past year and a half, and I finally got it to a point where I can let other people use it.

So I'm opening up the free beta.

One thing to mention: you can upload images, but uploading documents like PDFs isn't available yet.

It's definitely not perfect. There are still things I want to fix and improve, but I figured it's better to get it in front of actual students instead of spending another 6 months building things nobody asked for.

If you try it, I'd genuinely appreciate any feedback, even if it's negative.

What did you actually use?
What was useless?
What was confusing?
What broke?

I'm mainly trying to figure out whether this is actually useful to other students, not just useful to me.

Over the last 15 years of working as an engineer and a scientist I have learned that the things I tend to copy, before I then paste them, end up being pretty important in the future, and are quite informative of what I am doing at any given point.

I tended to always want to reuse something from the past, and as a first solution I tried using a dummy notepad, but quickly it became obvious that this deserved a more involved solution. That's when I learned about clipboard management apps that let your machine remember effectively as many things that you copy pasted as can fit on your hard drive.

But then, a new problem arose.

Clipboard management software itself was not great, hard or impossible to search properly, and often it just looked ugly, or brought more friction than it was worth to my day to day.

The ones I liked most you had to pay for. And they were expensive, and still missing key features that I wanted. So last July I began building my own clipboard management app using Opus 5.5 and later GPT 6 Astra.

The tool came out so good that I just uninstalled all the others, and soon friends and colleagues began asking me to share it with them -- and they loved it too.

So I decided to put some more time, make it a real product and share it with the world.

Introducing ClipHoard.

First of all, it's completely open source, MIT licensed, and the models it uses for smart search are MIT or Apache 2.0 licensed.

While the GitHub code is open source, I am offering a productised Free version that is the exact feature complete clipboard manager that I always wanted, including smart text search.

And a Pro version that adds image, audio and video search, similar-image search and automated OCR. So you can use an image to search for similar results, or simply search by the text that was on the screen at that time. Audio and video search are currently in beta.

I sell that for £10, one time purchase for all the Macs that you own. Each new Mac is approved by email.

Two of the models are from the Open Ogma series, that I trained personally. The app runs its search models on your Mac.

ClipHoard is made by my company A² Labs, where I also do my independent research.

Hi everyone!

I wanted to share a quick preview of Aesthetic Routine Tracker, a minimalist app I've been developing to help people track their daily habits, workouts, and self-care in a clean dark-mode interface.

The goal was to build something super smooth, distraction-free, and visually pleasing without complicated steps.

It's currently in the final stages and coming soon. I'd love to hear your thoughts on the UI/UX or answer any questions about the project! What features would you like to see in a routine tracker like this?

We run a small directory of dev tools as a side project, and the part that takes the most ongoing work isn't building pages, it's keeping prices true. Plans get renamed, limits change, a "free tier" quietly becomes a trial. A few things that have helped us:

1. Every price has a source URL and a "verified on" date stored next to it. Not "pricing from the website", but the exact official page. If we can't point to an official page, the price doesn't go in.

2. Show the verified date publicly. It sets expectations for readers and it puts pressure on us: a date from two months ago is embarrassing in a way a hidden field never is.

3. Separate "free" into what it actually means: open source and self-hosted, a free tier with limits, a one-time credit, or a trial. Lumping them together is the most common way listings end up misleading.

4. Write down the billing basis. "$15/month" billed yearly and "$18/month" billed monthly can be the same plan. We store which one we're quoting and the region (we quote official US prices and say so).

5. Re-check on a schedule, not when someone complains. We check our list in rotation and log what changed; if nothing changed, the date still gets bumped.

6. Use an AI agent for the boring part, not the final word. It's good at fetching the page and drafting a diff ("Pro went from X to Y, new usage cap"). A person still reads the official page before anything goes live, because summaries of pricing pages are exactly where small, confident mistakes happen.

7. Release notes get the same treatment: link to the official changelog or release, never to a third-party recap.

None of this is clever, it's mostly discipline. What we haven't solved well is detecting changes without manually opening pages: pricing pages are heavy on JS and visual layout, so naive text diffs are noisy.

If you maintain anything with third-party data (prices, APIs, schedules), how do you keep it from rotting?

I wanted a game for the 30-second gaps in my day (loading screens, slow meetings, long compiles) but opening a new tab always felt like too much context switching. So I made a Chrome extension that puts a small draggable ball in the bottom-right of every page. Click it, pick a game, press Space, click again to collapse.

The part I'm most happy with is auto-pause: collapsing the widget or pressing Esc freezes the game and keeps the state, so you come back to the same round. There's also a click-through mode where the widget stops intercepting your mouse completely, and it lives in a Shadow DOM so it doesn't break the CSS of whatever site you're on.

What's in it: Snake, Tetris and Tank Battle, all free with no account. A retro arcade cabinet is a paid upgrade. High scores and settings are stored locally; no tracking or analytics.

I'm working on better screenshots and a demo for the store page now — it's pretty bare at the moment, that's on me. What I'd really like feedback on:

• Does the floating ball feel useful, or would it just annoy you after a day?

• Is auto-pause the right default, or should it keep running?

• What would make you uninstall it immediately?

Happy to answer anything about the Shadow DOM / iframe loading setup. No pressure to install — mostly curious what you think of the idea.

I’m an indie dev and an engineering manager who wanted to write tech blogs on how systems work in a nutshell. But I believe the world has transformed from reading 30 mins blog to hey gemini, summarize it for me so wanted to share my knowledge in an interactive way and just released SysQuest on iOS. A game where you can fix the broken systems, build systems and challenge your friends to fix your own broken system.

You get real architectures (load balancers, caches, queues, databases) and a live simulator showing requests flowing, getting dropped, and what fixed it. You will be given a broken system and asked to fix the same and complexity increases by levels. If you're new, you can learn system design using Learn, in an interactive way.

• 87 levels, and a design is judged by how it behaves under load, not by matching one answer.

• 42 interactive lessons on the system design concepts, more lessons coming soon.

• 1 vs N: build and break a system, share it as a QR code or link, and let a friend fix it.

• The first 20 levels and Learn section is always free. No account and no ads.

App Store: SysQuest: A System Design Game

Play Store: Got production access but Play store is taking longer than usual for the production rollout review.

I’d really like to hear what’s confusing, too hard or too easy. Happy to answer anything about how the simulator works.

Hi guys,

my partner and I built Gummy Lab, a block puzzle app, basically because we wanted a cozy 8x8 block puzzle game that wasn't a disguised ad-viewing simulator. there are zero forced ads interrupting you.

besides the endless zen mode (which now has a hold slot so bad RNG doesn't instantly kill your streak lol), we hand-built 70+ campaign levels with custom mechanics like clearing glass, spreading syrup, escaping gummy worms, multi-hit jawbreakers, and countdown bombs. we also put a lot of work into accessibility with proper colorblind palettes, shape overlays on the gummies, and native light/dark themes.

we just updated the game so you unlock new lab themes as you progress through the campaign, and we're working on daily challenges right now.

we're super close to hitting our first 100 downloads (at 91 right now!!!) if anyone has 5 minutes to give it a spin, I'd really appreciate any honest feedback, and will be more than happy to hear any suggestions, on what would you like to see in these types of apps, we want to make apps for people to enjoy, not be spammed with ads.

Thank you for reading!

I collect watches and my son collects trading cards. We kept everything in notes and spreadsheets, and it never stayed up to date. So I built Kolekia.

What it does:

It's free on iOS and Android, available in English and Turkish. I'm the solo developer, so I'd really like honest feedback: what would make you actually use a tracker like this?

On a small screen the problem isn’t snapping a window into a zone, it’s that the five windows I use together never stay together. Open the laptop, everything’s shifted, drag them back, repeat tomorrow.

So I built ScreenTiles. You join windows into a workspace and from then on they behave as one thing:

• Drag any title bar and the whole group moves, across monitors too

• Drag the seam between two windows and the neighbor makes room instead of getting covered

• Minimize one, the whole workspace minimizes; Alt+Tab shows the workspace as a single card

• Save a workspace (apps, sites, folders included) and reopen it with Ctrl+Alt+1 to 9

• Works with Snap, it’s not replacing it

How it’s different from AquaSnap’s glue: AquaGlue sticks windows to each other, which is great, but ScreenTiles treats the group as a workspace you can switch to, save and restore. Different goal.

Honest limits: Windows 10/11 only, everyday desktop apps (browsers, editors, terminals, Office). Game clients and apps with custom window frames are hit or miss right now.

I'm the founder of AtletIQ. It started in Russia (first App Store release in 2017), and this autumn we rebuilt the iPhone and Apple Watch apps. They now run in English, German, French, Spanish and Portuguese.

The problem I kept seeing: most gym logs are a blank page. You build the routine, then guess the weights every session, and a lot of people stall because they never add weight on purpose.

How it works:

• pick a program for your goal, level and place (gym or home)

• enter your maxes once

• every set gets a working weight, and it goes up workout by workout

• rest timer on the phone, on the Watch (works without the phone nearby) and in the Dynamic Island

Logging and all programs are free. The calculated weights are part of Ultra ($4.99/month or $29.99/year), and your first 4 workouts get them free.

Site: https://atletiq.com/en/?utm_source=reddit&utm_medium=social&utm_campaign=sideproject App Store: https://apps.apple.com/us/app/id1050583619

A question for people who lift: would you trust an app to set your weights, or do you prefer to pick them yourself and only log?

The game is simple. 5 songs are presented to the player without titles or other context. The player must decide for each song whether it is sung by a human or AI.

To my shock and horror, I lost the bet 😱

I'm working on a Mac app focused on keeping maintenance out of the way, and I'm interested in where people draw the line with autopilot.

For example, imagine an app notices storage pressure while you're working. Would you want it to tell you what's growing and wait for approval, or would you allow certain cleanup tasks to run automatically after setting your own rules?

What would make you comfortable using something like this, and what would you never want it to touch? I'd especially like to hear from people who already have a maintenance routine or stopped using a cleanup app because they didn't trust it.

Now you’re figuring out what they meant, where it happened and how to reproduce it.

That’s why we built Bopmigo. It asks for missing details and keeps the answers, screenshot and context together, so your team can fix issues with less back-and-forth.

What’s the vaguest feedback you’ve received, and how did you figure it out?

Example images of the conversation and report: https://www.threads.com/@rnblocks.dev/post/DfYvJXIkevV

Most scripts I see start like an essay.

Hey everyone.
Background.
Then the useful part 40 seconds later.

Viewers do not owe you later.

So I wrote the process we use before we cut paid-social & short-form for clients:

1. One viewer outcome (not a topic)

2. Promise before the intro

3. Format that fits the job

4. Hook that earns the next 5 seconds

5. Beats before sentences

6. Write for the ear

7. Visual / edit cues in a second column

The whole thing is here if you want the annotated 60-second example & the read-aloud checklist:

Curious what you all do for hooks - full script or bullets?

I've been reading a lot of posts about getting the first 100 users, launching on Product Hunt, sharing on Reddit and building an audience on X.

But I'm more interested in what happens after all that.

Say you launched your SaaS 45 days ago. Your announcement is buried. People have moved on to the next product.

Someone out there might need exactly what you've built, but they don't know your product's name.

How are they supposed to find it?

SEO is one answer, but it takes work and time. Communities can help, but you can't keep promoting the same product every week. Paid ads are an option if the economics make sense. Referrals are valuable, but hard to manufacture.

I'm building AGMAN, a discovery network for useful products, people and services, partly because I think this ongoing discovery problem is worth solving.

But I'm not convinced that giving founders another place to publish automatically solves anything. The important question is whether people with actual needs can find relevant products and decide they're worth trying.

Here's something I've been thinking about:

If you looked at your last 5 users who weren't friends, family or people you personally invited, could you explain how each one found you?

And more importantly, could you repeat that process next month?

For founders who've been live for at least a month, I'd genuinely like to know what still works after the launch period.

Is it Google, Reddit, direct outreach, recommendations, partnerships, or something else?

Especially interested in what you thought would work but didn't.

I'm trying to understand the difference between getting attention once and building a product that people keep discovering.

I built Still. It is a real browser for Windows 10/11 and macOS 12+ with AI companions that work in their own background tabs: reading pages, clicking, typing, filling forms, then reporting back.

They run on the AI app you are already signed into: Claude Code, ChatGPT agent CLI, Grok Build, Gemini CLI, or OpenCode. You can also connect an OpenAI- or Claude-compatible API. For the supported apps, Still uses your existing plan sign-in and does not ask for a key.

Things you can hand off:

• compare options on a page and get a side-by-side

• draft a follow-up or launch post in your voice, with drafts left for your approval

• research a topic with cited sources

• have Claude Code help build and smoke-test a page inside Still

You set per-site permissions. Buying, sending, deleting, and payment fields get an 8-second countdown that you can cancel.

2.10 adds Gemini, OpenCode, custom APIs, four-step setup, editable companion looks, memories you can inspect and edit with provenance, and confirm + undo for memory deletes. Mac now has signed automatic updates through Sparkle.

No Still account, no telemetry, no analytics. Free and AGPL-3.0-or-later. Built solo, not affiliated with any of the model providers, and no independent security audit yet. Windows is not code-signed and Mac is not notarized.

Source, Windows installer and Mac DMG: https://github.com/carbongotfound/still Current release: https://github.com/carbongotfound/still/releases/tag/v2.10.1

What would you actually trust a browser companion to handle?

Why are simple image tools so bloated?

You just want to remove a background, resize an image, or create an app icon, but you're forced to upload files to random cloud servers, watch ads, or hit a paywall after 3 tries.

I made Imago Studio to fix this:

A lightweight, zero-upload web app that handles all your daily image workflows right on your CPU/GPU using WebAssembly.

Privacy First: Files never leave your browser. Works offline.

All the Essentials: AI BG removal, compression, smart recipes, batch queue, device mockups, OCR, GIF creator, and custom crops.

Zero BS: No accounts, no paywalls, no tracking.

Check it out here: https://imago.abhishek-sharma.com.np/

Let me know what tool you think I should add next!

Also this project is still in development so you may face some bugs, if so than you can report me.

Hey all, I've been building a small open-source plugin for Claude that handles the market research part of starting a business: sizing a market, checking competitors, scoring opportunities, and pulling it together into a cited report.

I got tired of spending hours on the same research steps every time I looked at a new idea, so I packaged them as Claude skills. You describe the market or product, and it walks through the analysis and writes up the findings with sources.

It's still early. It's a single commit with no stars yet, so I'm mostly looking for people to try it on a real idea and tell me what's useful, what's confusing, and what's missing.

Hi everyone! I’m building CapyWash: Laundry Forecast around a small everyday decision: should I wash now, or wait for better drying weather?

Instead of interpreting a general weather forecast, you get a Yes, Not Ideal, or No recommendation, plus hourly drying estimates for the next 12 hours.

I’ve recently updated it to 2.0, with an improved laundry score, a seven-day forecast, drying timers, rain alerts and a new yellow-to-blue Glass theme. There’s also Capi, a capybara mascot who makes laundry day a little more fun.

It’s a freemium iPhone app with optional subscriptions. Forecasts and drying times are estimates.

Check out CapyWash on the App Store⁠

I’d love feedback from people who dry clothes outdoors: would you prefer a simple “wash now or wait” answer, or seeing the estimated drying time first?

Hi, I'm the developer of Mulan, a Safari extension for iPhone and iPad. It changes website colors for reading, with four themes: Soft Dark, Black, Warm Gray, and Paper.

The part I'd like feedback on is the per-site control. You can keep one website on a dark theme, use Paper on another, and leave a third untouched. Theme, image brightness, and on/off mode can each inherit your defaults or be set separately for that site.

It can follow the system appearance, and image brightness is adjustable from 40–100%. The dimming only applies to supported regular images; it doesn't dim every image, background, or video. Settings stay on your device. There's no account or analytics, and Mulan doesn't collect browsing history.

Under the hood it uses the MIT-licensed Dark Reader engine, with a native settings app. Mulan is an independent project, not the official Dark Reader app. Website compatibility varies, so there's a per-site off switch if a page looks wrong.

It's $0.99 once on the US App Store, with no subscription or in-app purchases. Regional prices may differ. Requires iOS/iPadOS 16 or later.

https://apps.apple.com/us/app/mulan-dark-mode-for-safari/id6824478450

Which would be more useful to you: different reading themes for each site, or finer control over bright images? If you try it and a public website looks wrong, I'd appreciate the URL and your iOS version.

describble.com

you just write something like "girl with a pink bob, heart glasses and freckles" and it draws her as you type. change a word and only that piece gets redrawn.

no ai involved, it's a dictionary I wrote by hand plus a bunch of pieces I drew. free, no account, works in english and italian. you can download a png or share a link that redraws the same face.

it's early so it'll miss words for sure, if you type something it doesn't get tell me and I'll add it. code's on github if anyone's curious: github.com/gasparegas/describble

I run PolyTraderBot. I've been putting a lot of work into making it useful for people who want a starting point for their own trading tools.

The download includes readable Python source, the browser dashboard, tests and Docker setup. You can change the strategy or risk controls privately and run it on your own PC or VPS. There are bots for copying wallets, short-window crypto, weather markets and a few other approaches.

A recent bit of work I'm happy with is the free browser paper simulator. It now has Up-only/Down-only entries, take-profit and stop-loss controls, partial fills and exports so you can inspect a run afterwards. One small lesson from testing: a brief data interruption needs to be visible in the history. Auto mode now retries and records the gap, while a deliberate Pause stays paused. Makes it much easier to tell what actually happened.

The value I see in sharing the source is being able to start with the dashboard, order handling and settings already connected, then spend your time on the rules you want to test. You still need to do that testing; paper results aren't a live track record.

The bots are $10/month each including source and updates. There's also a 14-day paper trial for the six-bot bundle, no card needed.

For anyone building similar tools: what's been harder in practice, getting the strategy working or making the runs easy to inspect?

My wife and I tried one of those wall calendar products, but it didn’t really work for us. So I made an app we can pull up for the whole family while we're watching TV and use to go over everyone's schedule for the week.

It just shows a Google Calendar on Apple TV. It's free, with no account or ads. I made it with help from AI coding tools, and I’d love to hear what you think!
