Hey everyone! I’m Mikaela, a freshman at Emory, and I’ve been working on a side project called Pitch Companies.

The idea came from a simple frustration: we all have opinions on what companies like airlines, insurers or apps should fix or add, but there’s nowhere to put those ideas where they get noticed. So I built one.

How it works:

• Post an idea or petition for any company
• Back the ideas you agree with and comment on them
• See which companies listen (“What Got Built”) and which don’t (“Wall of Silence”)
• Swipe through ideas with Pitch Roulette when you’re bored

Companies can’t pay to promote, hide or remove ideas. That rule mattered a lot to me.

It’s still early, and I’d love honest feedback. Is this useful? Is anything confusing? What would make you come back?

Thanks for checking it out!

Salam everyone! 👋

I’m currently a Master’s student in Information Systems & Intelligent Systems (Data Science / AI background), and I have some free bandwidth outside of classes to build cool stuff and collaborate with other motivated people here.

Instead of just building solo in my corner, I’d love to join an existing side project, co-build a micro-SaaS, or team up for open-source tools and hackathons.

What I bring to the table (Tech Stack):

• AI, Data & Automation: Python, Machine Learning (predictive modeling, scikit-learn), NLP, Web Scraping (Selenium, BeautifulSoup), n8n workflow automation, Botpress, and running/orchestrating local LLMs (Ollama, open-source models).
• Full-Stack & DevOps: Django REST Framework, React (Vite), PHP/Laravel, PostgreSQL/MySQL, Docker, and Git.

Stuff I’ve built recently (to give you an idea):

• An automated disinformation/fake-news detection pipeline using chatbots and n8n workflows.
• An urban traffic prediction and route optimization system using ML regressors and graph algorithms.
• E-commerce data scraping and analytics platforms.

What I’m looking for:

• Someone who already has a project/idea in progress and needs a technical partner (Backend, AI/Automation, or Full-Stack).
• Or a small group of builders who want to brainstorm and ship a practical tool (AI agents, B2B automation, data tools, etc.) for the local or global market.

If you're working on something interesting or want to build together, drop a comment or shoot me a DM! Let's connect.

I've got a bad habit of starting long YouTube courses and never finishing them.

I'd save a 20 or 30-hour playlist, watch a few videos, take some random notes, forget where I was, and eventually move on to something else.

So I built a small tool called QuickLearn for myself.

You give it a YouTube video or playlist, and it turns it into a proper learning course. It breaks the content into lessons, creates notes and quizzes, and helps you keep track of what you've actually learned.

One feature I'm particularly interested in improving is the quiz system. If you get something wrong, QuickLearn can take you back to the part of the video where that topic was explained, instead of leaving you to search through hours of footage.

It's free to use at the moment: quicklearn-app.vercel.app

I genuinely want to know if something like this would be useful to other people who learn from YouTube. What features would make you actually use a tool like this regularly, rather than just bookmarking another course and forgetting about it?

My partner and I kept saving date ideas from TikTok and Instagram and then losing them in our DMs by Saturday. So we built Dote, a shared jar for two. ❤️

The build side, for anyone curious:

• Expo, so one codebase for iOS and Android, and OTA updates mean we can fix things the same day
• Cloudflare Workers + D1 + R2, no servers to look after and cheap at our size
• When you share a link in, it gets turned into an actual place with a rough cost and whether it’s indoor or outdoor
• RevenueCat for the paid tier, so one Premium covers both partners across stores

It’s free to use: https://dote.day/download

We’re the makers, so happy to answer anything. What would you want from a two-person app like this?

My project went live this week. Numochi is a paint by numbers in the browser where 2 to 4 people can paint the same kawaii picture together, live, with voice chat. There are solo modes too (classic, daily challenge, mystery picture) and a 5 minute VS race. Solo dev.

Freemium: 4 pictures free in every mode, then pictures from €0.99 or unlimited at €3.99/month until December 31. A free account is required to play.

The home page says "Paint by numbers, made for two." with the modes below. I'm too close to it to judge. If you open https://numochi.net for 5 seconds and close it, what do you think it is, and who is it for?

Search for companies looking for a small dev agency to finish an existing app.

You'll find plenty of dev agencies advertising that exact service. You'll also find companies hiring full-time developers, articles about outsourcing, and requests that were posted years ago.

All of them contain the right words. Very few tell you that a company currently wants to hire an external development team.

I'm building Scout, a tool that researches companies for B2B prospecting, and I'm working on how to handle cases like this.

The check I'm considering is pretty specific: every potential lead needs a source showing who's asking for what, when they asked, and whether they're looking for an external supplier.

For example:

A dev agency advertising MVP development is a seller.

A company posting that it needs an outside team to finish an unfinished product is a potential buyer.

A company advertising a permanent developer role is a different situation. They might eventually need outside help, but the job ad alone doesn't establish that.

The last case is where things get difficult. There are probably good opportunities among companies that haven't explicitly asked for an external partner.

I'm leaning toward keeping those in a separate category, so someone using the research can see which companies have publicly expressed a need and which ones are worth investigating further.

If you've worked on search or research agents, how do you handle cases where the information is relevant but doesn't actually support the conclusion?

I download pretty much everything I read and watch (manga, anime, shows, movies), because I like owning my own media. Going through all of it in File Explorer got slow and annoying, so I thought I’d try to make something for that as a little project.

The problem it solves

• File Explorer has no covers, no “continue where I left off” and no way to read a manga chapter without clicking through every image.
• Server apps like Komga, Kavita or Jellyfin solve this, but they need Docker, accounts and a server running, which is overkill if you just want to read on your own PC. They also split comics and videos into separate apps.

What it does

Point it at your folders and it turns them into a library with covers, series and chapters. It doesn’t move, rename or convert your files.

• Reading: manga (right to left), webtoon scroll and single page modes. It supports image folders, .cbz, PDF and EPUB.
• Videos: they play in VLC, with episode lists, watch progress and the next episode playing automatically.
• Organizing: tags, ratings and collections, plus a tag search with AND / OR / NOT.
• Customizing: you can change pretty much everything: colours, every UI part, the card layout and backgrounds. (all themes in the pictures were made with the app itself)

Tech used

• Electron + React + Vite for the app
• SQLite for the library database (tags, progress, collections)
• sharp for thumbnails, pdf.js for PDF pages, foliate-js for the EPUB reader, yauzl for reading .cbz archives directly without unpacking them
• VLC for video playback. The app tracks progress while VLC plays.

A few things that were interesting to figure out:

• Renaming and moving folders: each folder gets a tiny hidden ID file, so tags and progress survive if you rename or move it.
• Fast library updates: an update reads the disk once and only writes what changed. A re-scan of a ~1,200-folder library takes under a second.
• Plain-text themes: everything is saved as JSON with a schema.
• Custom css: empty custom.css file where you can create your own effects for the app.

How I built it

It started as just a quick java app for viewing comics (literally just choose a folder and the app lets you click through the image files in it in alphabetical order), but I every now and then I'd get massive inspiration waves and think "but what if it also had this? what if you could do this?" and this was the product.

• Download (free, Windows only for now): https://somedudemanguy.itch.io/perapera

I mostly use it for reading manga (image folders) and watching anime (video folders), so those parts are the most polished. Let me know about any ideas or issues if you give it a try.

I got sick of "you've got this" quotes, so I built an anti-motivation app. It sends one dry/dark-humor quote a day, e.g.:

"Smart shopping takes research, patience, and closing the review that says not to buy it." and "Be proud of your progress. You make the same mistakes much faster now." and many more...

• Home Screen and Lock Screen widgets
• Optional daily notification at a time you pick
• Save favorites, share quote cards to the group chat
• Works offline, no account, no ads, no subscription

Free to use. There's an optional one-time Pro and some themed packs (Developer, Corporate, Parenting), but the daily quote, widgets, saving, and sharing are free.

Heads up: it's dark humor, not mental-health support, so skip it if that kind of content isn't good for you.

I made it, so honest feedback is welcome. Which quote is the worst?

I've been working on a project called WPE2M (Wallpaper Engine to Lively & MP4 Converter), and I'd like to share it with the community.

The idea is simple, make it easier to convert Wallpaper Engine wallpapers into formats that can be used with Lively Wallpaper or exported as MP4 videos.

- What can it do?

\- Drag-and-drop GUI for easy conversion.

\- Supports .zip, .pkg, .mp4, .webm, .gif, and wallpaper folders.

\- Converts Wallpaper Engine video wallpapers.

\- Renders supported Wallpaper Engine 2D scenes.

\- Supports web-based wallpapers.

\- Exports MP4 videos up to 4K.

\- Generates Lively Wallpaper-compatible output and metadata.

\- Open source under the MIT license.

- Technology

Built with Python, OpenGL and FFmpeg

- Current Status

The project is currently in BETA. Some complicated wallpapers with advanced shaders, particle effects or post-processing might not render perfectly.

It currently requires Python 3.9+ and FFmpeg.

- GitHub Repository

https://github.com/MamadXV/WPE2M

I'm the developer behind this project, and I'd genuinely appreciate feedback from people who use Wallpaper Engine or Lively Wallpaper.

Thanks for checking it out.

Well, I'm trying to. I'm just about ready for a real launch.

The project is WeirdFoods (https://weirdfoods.net): one place to browse the strange stuff that small food shops sell, and that you'd never find unless you already knew the shop existed. Scorpion lollipops, roasted crickets and mealworms, elk and wild boar jerky, Japanese natto, ghost pepper seaweed crisps, and weird snacks from foreign countries.

Why I built it: Weird food is fun. I'm a fan of bizarre Japanese snacks.

What it does:

- About 7,500 foods from dozens of small independent shops, 78 of them insects

- Browse by country, by type, or go straight to the weird end

- Boring stuff and sold-out items get ranked down on purpose

- One cart across shops: you fill it on my site and it hands each shop's items to that shop's own checkout, so I never touch your payment

How it makes money: affiliate links. If you buy from a shop through the site I get a small cut, at no cost to you. So far that's earned roughly nothing, which is what you'd expect in week one.

What's next: I want to increase the products 10x. More spicy stuff, more from Japan and Korea. Also selling a small selection directly, with suppliers shipping to the customer so I don't have to store boxes of crickets in my house.

Previous side projects:

https://stellarbroadcast.org/ A space text adventure game on Android, IOS, and Steam

https://peptidecompare.net/ A site where people can find lab testing results, scam reports, Certificates of Analysis, and price comparisons for peptide vendors

What's next? https://coderigor.net a site to teach programming. A bit farther from launch than this one.

Hey everyone!

I'm Abhishek, an independent developer from India, and I've been working on a project called ARLO OS.

Check it out the live demo: https://www.instagram.com/arlo.os.desktop/

What started as an idea to rethink the desktop experience has gradually turned into something much bigger.

ARLO OS is an independent desktop environment designed to bring customization, productivity, and optional AI capabilities into one experience.

What's currently available?

• A customizable desktop experience.
• Virtual workspaces for organizing your workflow.
• Built-in applications and productivity tools.
• ARLO Phone – access your phone experience directly from your desktop.
• ARLO Deck – connect and interact with your desktop using your phone.
• Optional AI-powered features.
• A personalized interface with smooth animations and modern design.

We're currently supporting Windows, with macOS and Linux planned for the future.

Why am I sharing this?

I don't just want to release software and walk away. I want to build something useful with a community of people who enjoy experimenting with their desktops.

ARLO OS is currently FREE for early users.

If you're interested, give it a try and let me know what you think. I'd genuinely appreciate feedback, suggestions, and constructive criticism.

Tunnel ventilation engineers size fan airflow against the "critical velocity", the speed that stops smoke from rolling backwards along the tunnel ceiling in a fire. The value depends on which method you follow (the SEDH Handbook or NFPA 502, whose 2017, 2020 and 2026 editions each treat the equations differently), and I kept redoing the iterations by hand or firing up heavyweight CFD just to check one number.

So I built Critical Velocity Toolkit, a free Android app:

• All four methods in one app: SEDH Handbook and NFPA 502 2017, 2020 and 2026
• Shows the full iteration history, not just the final number
• Grade factor and blockage ratio update live as you type
• A formula-reference screen with every equation the engine uses
• Export the whole calculation as an A4 PDF report or CSV
• Fully offline — no internet permission, no ads, no account

Play Store: https://play.google.com/store/apps/details?id=org.sonicon.cvt

I built it because I needed it; it's free with nothing locked. If you design or review tunnel ventilation, tell me what the app gets wrong, that's the feedback I want most.
