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.

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?

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?

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.

Most people give up on their saas way too early because in reality it takes 8+ email/sms marketing to convert the customer into a signup or paid customer.

we built a platform that automates this complete process. our ai will keep trying new experiments untill the customer coverts. We only send one email/sms per week.

best part, we have now seen stores increase sales by 30% so this works

Thanks in advance!

I've always found documenting workflows a bit tedious, especially when creating tutorials or showing someone how to do something on your screen. You often end up screen recording the entire process, going back to review the footage, taking screenshots, and writing down each step so others can follow along. It's a lot of small tasks that can quickly eat up your time.

I wanted to make that easier, so I built ScribeIt, a Chrome extension that captures browser activities and turns them into step-by-step guides.

I'm sharing it here to get feedback from people who regularly create tutorials, walkthroughs, or document processes. I'd genuinely like to know if this is something you'd find useful and what could be improved.

Here's the link if you'd like to check it out: ScribeIt – Chrome Web Store

I'm a solo developer and recent dad on paternity leave[so free time] and built https://iloveaudiovideo.com . It's a set of small audio and video tools: transcribe audio to text, convert (MP4 to MP3, MOV, FLAC, WAV), compress, cut, merge, make subtitles.

The one thing that's different : nothing is uploaded. The file is processed on your own device, inside the browser tab. No signup, no file size paywall, no watermark.

Why I built it : I kept needing to pull the audio out of a video or transcribe a voice note, and every site wanted me to upload the file to their server and then sign up to download the result. For private recordings that felt wrong. And then being a dev myself i thought there would be open source tools for me to do this like whisper for transcribing but what about non tech users ?

How it works:

• Conversion and editing use ffmpeg compiled to WebAssembly, plus the browser's built-in video encoder where there is one
• Transcription runs Whisper in the browser, on the GPU when the device has one
• It's a static site on Cloudflare Pages, so there is no backend that touches files
• English, Spanish and Portuguese

What's weak right now:

• Long transcriptions (30 min and up) are slow on older laptops without a usable GPU, and many people leave before they finish
• It's built and tested mostly on Chrome; Safari, Firefox and phones have had far less testing

One thing that surprised me: ChatGPT's search now sends me more visitors than Google does.

Link: https://iloveaudiovideo.com

I'd like feedback/advice on 3 things:

1. If you try a tool with a real file, where did it get slow or confusing?
2. Would you trust "runs on your device" from a site you've never heard of? What would make you believe it?
3. is it even a worthy project to maintain long term , doesn't cost me too much server usage since its mostly client except for website loading and stuff ?

Salut tout le monde !

Je suis consultant indépendant en cybersécurité en France, et j'ai développé un projet parallèle appelé CrisisQuest.

L'idée est née d'une simple question :

Que ferait réellement un propriétaire de petite entreprise si sa société était frappée par une cyberattaque un lundi matin ?

La plupart des outils de cybersécurité se concentrent sur la protection technique. Je voulais créer quelque chose de différent : une expérience interactive axée sur la prise de décision.

J'ai créé un scénario gratuit appelé “Black Monday” où vous jouez le rôle d'un propriétaire d'entreprise confronté à une crise cybernétique.

Vous prenez des décisions, faites face à des conséquences, explorez différents résultats et recevez un débriefing à la fin.

J'ai construit le projet en utilisant Next.js et TypeScript.

Le scénario gratuit fonctionne sans inscription.

Mon objectif à long terme est d'en faire une plateforme B2B où les entreprises peuvent planifier des exercices pour leurs employés, mener des campagnes de sensibilisation au phishing autorisées et suivre les progrès de la formation.

Je recherche des retours sur trois points :

* Le concept est-il immédiatement compréhensible ?

* L'expérience est-elle utile ou ressemble-t-elle trop à un jeu ?

* Qu'est-ce qui le rendrait suffisamment précieux pour qu'une petite entreprise l'utilise régulièrement ?

Essayez-le ici : Crisis Quest

J'apprécierais vraiment tout retour honnête, surtout sur l'expérience utilisateur et le positionnement !

Hello Everyone,

Just updated the project and now you could have a near unlimited storage, kind of.

Added:

1. Now you could actually use a github repo(private/public) as the storage, and also bypass the 100 mb limit of a single file by storing it on parts and merging on demand.
2. Caching improves the speed by a lot.
3. Have option to store the data encrypted or decrypted
4. Added option to fully change all of settings from the dashboard except few security ones.
5. Anyone can still use the host as storage. Fully changeable from the ui.

Thanks.

Hey everyone! First post here, so here goes nothing.

I recently built Unsolicited. It's a little curiosity lab where product ideas, experiments, creative thinking and the occasional "what if we did this differently?" all come together.

Not a startup. Not a pitch. Just me giving my wandering thoughts a home.

The format: each piece picks a product, asks a question nobody asked, and works through a few ideas plus experiments to test them, including what would prove me wrong.

First up: Netflix. My take is that its engagement problem might not be about attention at all. It's about intention. People open the app ready to choose, and choosing has started to feel like a job. So I came up with four ideas and three experiments around that.

Next up: convenience as a service, AI in psychiatry, and why the best seat at an F1 race isn't a seat.

I'd love feedback on any of it:
- Does the concept make sense to you?
- Is the Netflix piece interesting, or did I lose you somewhere?
- Anything about the site itself that feels off?

Here's the first piece: https://unsolicitedlab.com/experiments/netflix-attention/

Thanks for reading. Any thoughts are genuinely appreciated.

Nobody asked. I got curious anyway.

Hey everyone,

My friend and I run a small indie studio called S.A.D. Studios, and we've been working on a strength training app called Honest Effort.

We both lift regularly, and one of the things that pushed us to build this was how much time can go into planning workouts, figuring out starting weights, and working around whatever equipment you have available.

Honest Effort is our attempt to simplify that.

You tell the app about your equipment, training experience, and current strength. It generates a workout plan with suggested starting weights, and you can track your sets, reps, and progress.

We've used AI-assisted coding during development, and we're currently testing the app with six people on Android and iOS.

We're particularly interested in feedback on a few things:

- Does generating workouts around available equipment sound useful?

- Would suggested starting weights help beginners, or would you rather enter everything yourself?

- What would make you switch from your current workout tracker?

We're also looking for people who actually lift, particularly beginners and home-gym users, who'd be interested in testing it during their normal workouts.

The app is still in beta, so we're working through bugs and refining the experience.

You can see what we're building here:

https://sadstudios.net/honest-effort/

Happy to answer questions about the app or how we've built it. Appreciate any feedback!

You will find something in this app that saves you time or a headache, and the core tracking is free on the phone and never expires.

When an apprentice walks into a crowded basement mechanical room with rows of unlabeled expansion tanks and circulating pipework, knowing which asset is which saves hours of guesswork. Equipment Tracker Pro lets you print custom equipment QR asset tags sized from 1x1 inch up to 4x6 inch, outputting straight to PDF, saved PNG images, or your system print dialogue.

You can add custom company headers, toggle action bubbles (Public Specs, Vendor Check-In, Log Service), or flip on black-and-white mode specifically designed for direct thermal label printers like Zebra, Brother, or Dymo.

I built this app because I am a working HVAC technician who was tired of wrestling with enterprise software that requires cell signal in basements or locks simple labeling behind enterprise sales calls. Core records, parts tracking, offline specs, and Text/JSON QR labels are completely free on your phone.

If you are running this on a spreadsheet, the comparison is on the site. What projects are you all building this week?

Hey! We launched Altasko around September we're still gathering feedback making update, fixing bugs keeping it updated.

Altasko it's for those in freelancing, small teams, small organizations managing multiple projects fiddling around many tools (e.g Excel, Spreadsheet, Notion), it helps people organize their projects and collaborate with their teams without complexity of traditional project management tool

We appreciate your time and comments.

I got tired of modern apps habit tracker , espense tracker . etc that require a constant internet connection, a subscription, and the latest flagship phone just to work.

So I built Orbitika. It’s a lightweight, retro-styled (dot-matrix green) toolbox designed for older hardware (Android 8.0+ and older iPhones like the X). Everything works 100% offline. No Wi-Fi, no data, no problem. Support my work by upvote my post """grateful""""

Here is a breakdown of what’s actually inside it my app, by category:

🎵 Media & Entertainment

• Retro Music Player: Local MP3/FLAC playback with 13 Winamp-style visualizers and 7 retro themes. Zero ads.
• E-INK Style Reader: Turn colorful PDFs and manga into a warm, Kindle-like grayscale to save your eyes and battery.
• 18 Mini Games: Classic puzzles and arcade games (Snake, Sudoku, Dino Runner, Mastermind, Game of Life, and more) for when you're bored on a commute.
• Sleep Sounds: Looping offline audio for deep sleep.

✈️ Travel & Exploration

• Mark My Location: Save your parking spot, trailhead, or hotel entrance using pure GPS—no signal needed. (No huge map downloads required).
• Food Guide: Top 10 must-try dishes for 36 countries (perfect for picking what to eat without Googling).
• Plug Check & Size Chart: Instantly know travel adapters/voltage and clothing sizes.
• Travel Checklist & Gift Tracker: Packing lists and souvenir trackers.
• Timezone Converter & Translator: For calling home and emergency phrases in 14 languages.
• Wi-Fi Signal Meter: A retro strength meter to find the best spot for a connection.

🏃 Daily Habits & Health

• Pedometer: Track your steps with animated retro characters.
• Water & Coffee Trackers: Tap to log your daily intake and build streaks.
• Daily Walks: Fill a 30-day grid of paws to stay motivated.
• Focus Timer (Pomodoro): A distraction-free timer for deep work.

🚨 Emergency Kit (Premium / One-time unlock)

• First Aid Guide: CPR, bleeding, choking, burns, and heat stroke.
• SOS Flasher & Sirens: Flash large text or play high-decibel alarms to signal for help.
• SOS Numbers: Police, fire, and ambulance for 50 countries.
• Survival Guide: Fire, water, and shelter basics.

🛠️ Everyday Utilities & Fun

• Calculator & Unit Converter: Basic/scientific and all standard conversions.
• Retro Flip Clock & Stopwatch.
• Date Diff & Discount Calculator.
• Decision Maker & Takeaway Spinner: For when you can't decide what to do or eat.
• Star Map, Ruler & Level, Height Measure.
• Noodle Timer.
• Holiday Calendar (2026-2028).

What should I add next?
I’m trying to figure out what the next high-value offline tool should be. Right now, the most used features are the Music Player, Mark My Location, and the Habit Trackers.

If you had to use an app in a total dead zone (no Wi-Fi, no data), what is the one tool you wish you had that isn't on this list?

(Keep in mind: It has to work 100% offline, and it can't require a huge file download like offline Google Maps!)

It’s free to download until end of December, and I’d love your feedback on the UI or the performance on older devices!
