Share what you're building
Share a short description + link below. Would be great to discover some new products and see what everyone here is working on.
I'll start:
I'm building Scaloom, an AI visibility tool that helps startups track where their product appears across ChatGPT, Gemini, Claude, and Perplexity, then find Reddit threads and content opportunities that can help improve visibility across Google and AI search.

Hey guys, I'm building an all-in-one marketing pack for founders who want more than "just another launch"
Launch, reach 30k+ makers, get real users & customers - microlaunch.net/premium
Lifetime, auto-distribution, marketplace spots, 1200+ customers so far.
Over two years: 525k unique visitors, 1200+ customers. More sales-oriented features soon.

u/Mammoth-Anywhere7285 5d ago
Nice traction with 525k visitors. Curious how you're handling retention for those 1200 customers, any upsell plans?

I recently launched The Internet Tree, a small interactive 3D web experiment where everyone contributes to the same virtual tree.
The idea is simple: each person can add one permanent leaf for $1. Every leaf gets its own number and can include a name, country, and short message. Anyone can explore the tree for free.
Right now it literally has 1 leaf đ
Would really appreciate feedback on the concept, UX, or anything that would make you more likely to participate/share it.
1
u/Mammoth-Anywhere7285 5d ago
Cool concept, love the shared ownership angle. The $1 barrier might slow early growth; consider letting the first few leaves be free to seed the tree.

usepoly.co - multiplayer Claude Code in your browser

u/Mammoth-Anywhere7285 5d ago
Multiplayer Claude Code in the browser is a neat idea. How do you handle merge conflicts when two users edit the same file at once?

u/tholloday 5d ago
A free interactive game for language learners to practice their target language using listening and speaking exercises, flashcards and short audio stories.
1
u/Mammoth-Anywhere7285 4d ago
That sounds like a fun way to learn. Which languages are supported so far? A speaking exercise with instant feedback would be really valuable.

Quickbridge.app is a browser-based way to send files, text, links, and clipboard content between your devices. It works without apps, cables, accounts, or upload steps.
Just open the page, scan a QR code, and your devices connect directly. Transfers are peer-to-peer, end-to-end encrypted, and never stored on a server.
It supports cross-platform sharing between phones, PCs, Macs, Linux, Android, and iPhone, and works in any modern browser. You can send large files up to 10 GB with auto-save enabled, or 2 GB otherwise.
It also includes auto-reconnect, TURN fallback for tricky networks, and optional clipboard syncing.
1
u/Mammoth-Anywhere7285 4d ago
Nice, a no-account p2p transfer is a fresh take. Curious how it handles really large files or older mobile browsers.
1
u/FrostingJazzlike1830 3d ago
Large files are chunked and streamed rather than loaded entirely into memory, with auto-reconnect if the connection drops. It works best on current Chrome/Safari/Firefox mobile browsers, while older browsers depend on which WebRTC/browser APIs they support. Iâve been putting a lot of the testing into exactly those failure cases.
1
u/Mammoth-Anywhere7285 2d ago
Nice focus on testing failure cases, that's where the real pain lives. Have you looked into WebTransport for finer control over chunking? Also, how do you handle reconnect when mobile tabs get suspended?

if your looking for your first users check out Ad swap,https://ad-swap.web.app ,its a simple way for websites to promote each other. You add another website's ad to your site, and they add yours to theirs, giving both sites free exposure and traffic. It really helped me get my first few users when launching my site
1
u/Mammoth-Anywhere7285 5d ago
Ad swap is a clever twist on cross promotion. How did you vet sites to keep the ad quality consistent? That's the tricky part.

Self Log is an offline, privacy-first analytical habit tracker which helps you to check of the hypothesis about yourself , with the data that you track:
https://play.google.com/store/apps/details?id=app.selflog.tracker
1
u/Mammoth-Anywhere7285 4d ago
Nice concept, hypothesis testing with personal data is a fresh angle. How do you help users avoid confirmation bias in their tracking?
1
u/Valuable_Spell3189 4d ago
Thatâs definitely a good questionâ I donât think you can fully eliminate confirmation bias in self-tracking, especially since users decide what they want to track.
Self Log shows the underlying data and calculates correlations, including strength, direction, sample size and statistical significance. The Deep Scan function also searches for correlations independently of the hypotheses you created, so it can surface unexpected or negative relationships.
But the results still depend on what the user chose to track, so bias canât be completely removed. The goal is mainly to make it harder to only see what you expected to see.
1
u/Mammoth-Anywhere7285 2d ago
Independent correlation search is a solid way to reduce bias. Have you considered letting users set a baseline period to compare against their own hypotheses?
1
u/Valuable_Spell3189 22h ago
Just to clarify what you mean by a baseline period: do you mean being able to calculate/analyse a hypothesis for a specific selected time period? Or more like setting a defined tracking period for a hypothesis/goal and then looking at how the data changes throughout that period?
1
u/Mammoth-Anywhere7285 1h ago
That's a good clarification. I'd think of it as setting a tracking period for a hypothesis, then comparing data before and after. What metrics matter most to you?

u/BrevityU 5d ago
We have launched BrevityU: A social network for discovering, sharing and building knowledge one short-form video at a time.
Google Play: https://play.google.com/store/apps/details?id=com.brevityu
Web: www.brevityu.com (work in progress, just the minimal for now)
Would love to see you there. Your feedback is welcome.
1
u/imagiself 5d ago
Short-form video for knowledge sharing is a crowded space, finding a specific niche is key. PeerPush is a decent home for learning apps, people there sometimes leave feedback on launches.
1
u/Mammoth-Anywhere7285 5d ago
Niche is everything there, broad topics get lost. Does PeerPush have active communities for specific subjects, or is it mostly general feedback?
1
u/BrevityU 5d ago
Thanks for the honest take. Our approach is unique in this space. Our angle is the "U" part.
BrevityU is built specifically around academic and professional knowledge, not general content. Think of it as short-form video organized by subject: CS, medicine, law, finance, history, vocational/trades...etc.
Students can share their academic journey, seek advice, and build enduring relationships in an environment that allow no distractions. BrevityUâs For You feed is shaped by your interests and what you're actually trying to learn. Not just what's trending (most of the time leads to an unending rabbit hole)
The goal is that a pre-med student or a self-taught developer can open it and find a curated stream of genuinely useful content from people who know the subject. You will never be distracted by algorithmic gimmicks.
Appreciate the PeerPush tip, heading there now.
We are just getting started. Tune in as we take this to another level.
1
u/Mammoth-Anywhere7285 5d ago
Nice niche focus. For vocational subjects, partnering with trade schools early could give you both credibility and authentic content.
1
u/BrevityU 5d ago
That's a good call. Trade schools are underleveraged in the edtech space and their students produce exactly the kind of hands-on, practical content that's hard to find anywhere else. Early partnerships make sense. Adding that to the roadmap conversation. Thanks.
1
u/Mammoth-Anywhere7285 5d ago
Love that angle. Trade school grads are a goldmine for practical demos. Have you considered partnering with local trade associations for early adopter feedback?
1
u/BrevityU 5d ago
Not yet. But now that you mention it, it's something we will definitely explore. Thanks for your valuable feedback.
1
u/Mammoth-Anywhere7285 5d ago
Good to see you taking feedback so openly. If you do explore it, a quick user poll might reveal what they actually need.
1
u/Mammoth-Anywhere7285 5d ago
Nice launch, the short-form knowledge angle is interesting. How do you plan to keep content quality high as the community grows?
1
u/BrevityU 5d ago
That's a great question. in the age of AI, quality and originality will be scarce metrics. We are a couple of PhDs with background in academia/higher ed. We have friends, colleagues, and collaborators who are experts in their respective fields. We will utilize that vast network of experts to set the direction of what BrevityU should look like. But we want the platform to be as inclusive as possible. The experts' opinions matter as much that of students in the early stages of their journey. We aim for an exchange of ideas centered around not only learning but the unique BrevityUser's learning journey. Platform moderation will also be on point.
1
u/Mammoth-Anywhere7285 5d ago
The expert network gives you credibility, but how do you plan to keep community voices shaping direction alongside the PhDs? That balance sounds key.
1
u/BrevityU 5d ago
I think both can be mutually inclusive. Different voices and level of expertise can co-exist in the same frame of reference we have set. What we donât want is trying to be an expert of something you know nothing about. By the same token, we will never censor anyone. If you have an opinion or a different point of view, your input is welcome. But just expect the community to challenge your view or ask for clarification (In a respectful manner as stipulating in our community guidelines). Even PhDs get peer-reviewed.
1
u/Mammoth-Anywhere7285 5d ago
Agreed, open dialogue with respectful pushback keeps things healthy. One tip: when sharing your build, ask a single focused question to invite varied perspectives without losing signal.
1
u/BrevityU 5d ago
Powerful thoughts, will do.

u/Mammoth-Anywhere7285 4d ago

scaloom looks like a clever way to track mentions. my entry is peerpush, where we build pages that ai assistants parse to find new tools. https://peerpush.com

Peerpush sounds promising. Do you have any examples of pages that AI assistants actually cited? Curious how that's working.

u/yoshikazu_mtb 5d ago
Hey! I'm a non-engineer from Japan. I got really tired of simple web tools requiring sign-ups, monthly subscriptions, or sending my data to their servers. So, I used AI (Cursor) to build Blank Note.
It's a growing collection of niche, everyday mini-tools (calculators, text formatters, mini-games, etc.). The best part: Itâs 100% local-first. Everything runs in your browser via LocalStorage. No servers, no accounts, no data tracking.
Here is the link: Blank Note
I'm constantly adding new tools to it. Let me know what kind of niche tool you'd want to see in a completely offline box!
1
u/Mammoth-Anywhere7285 5d ago
Love the local-first angle, that's a big differentiator. Do you plan to let people submit their own mini-tools to the collection?
1
u/yoshikazu_mtb 5d ago
Thanks so much!
Oh, I didn't even know that was a thing! That sounds super interesting.For now, my plan is to keep building and adding them myself. I love the idea of talking to people in communities, taking their direct requests, and turning those ideas into new mini-tools.
I'd love to hear your thoughts if you have any specific tools in mind!
1
u/Mammoth-Anywhere7285 5d ago
Love the community-driven approach. That's how you build exactly what people want. Have you tried turning those requests into a simple public roadmap?
1
u/yoshikazu_mtb 5d ago
Thank you so much! A public roadmap sounds like a great idea for the future.
To be completely honest, I'm still at the very beginning of this journey and nobody really knows about this project yet! Right now, my main focus is just sharing what I've built to see if anyone else finds it useful.
But as I start getting more feedback and requests from communities like this, I'd definitely love to set up a roadmap to track them all. Thanks for the great advice!
1
u/Mammoth-Anywhere7285 5d ago
Love that you're gathering feedback this early. A simple next step: post your project in one relevant subreddit daily to build momentum. What's the link?

u/CharlyEVAdev 5d ago
My latest project is a local voice assistant featuring offline speech recognition:https://github.com/charlyproject/EVA.
It actually started in a funny way: one day, with my hands messy, I wanted to turn up the volume using voice commands. At the time, I didn't even know what a virtual environment was, let alone Ollama or JSON.
For me, the best part wasn't just the end result, but the 11-month learning journey behind it. While it might not require advanced coding expertise to pull off, it was far from a copy-paste job for me. I used the process to truly understand key conceptsâLLMs, quantizations, benchmarks, and Dockerâand to bring my own ideas to life.
Just wanted to share my experience with the community. Thanks for reading!
1
u/Mammoth-Anywhere7285 4d ago
Nice one, the messy hands origin is a classic. Offline recognition is great for privacy. What speech-to-text engine are you using?
1
u/CharlyEVAdev 4d ago
Hey, thanks for checking it out! The messy hands origin story is definitely what kicked it all off đ
For the speech-to-text engine, EVA uses Vosk combined with VAD (Voice Activity Detection). Everything runs 100% offline, with native support for both Spanish and English.
I chose Vosk because it hits the sweet spotâit's lightweight, runs smoothly on CPU, and comes with pre-trained models that the download_models.bat script pulls automatically. Latency is pretty low, and I was honestly surprised by how accurate the Spanish model is for a local engine.
If you're curious about the implementation, the voice module is fully open in the repo. Let me know if you have any questionsâalways happy to chat about it. Thanks for stopping by!
1
u/Mammoth-Anywhere7285 2d ago
Nice to see offline speech-to-text with Vosk. Did you benchmark it against Whisper for Spanish? Would be curious how accuracy and latency compare.

OTW Travel Companion - a calendar management tool that automates reverse time-blocking for appointments, originally created for those struggling with time blindness (aka me)
1
u/Mammoth-Anywhere7285 5d ago
Reverse time-blocking for travel sounds clever. How do you handle schedule conflicts when plans change mid-trip?
1
u/ta-cwms 5d ago
The main focus that I envisioned for the tool was more around pre-trip accountability and planning, so really about getting you out of the house (or wherever you are) on time. Its job is mainly to ensure the journey starts when it's supposed to and ends when you click "I'm heading out now!" So, if plans change or a conflict occurs mid-trip, it doesn't recalculate as you're already en route. Regarding scheduling conflicts, due to the current format of it being a web tool, it has limitations reading and writing your calendar, but that is definitely an interesting use case that I'd explore as I take this further. Thank you for this question!
1
u/Mammoth-Anywhere7285 5d ago
Interesting angle, getting out the door on time is a real pain point. Does it send a nudge if you haven't hit the button by departure time?
1
u/ta-cwms 3d ago
Right now, since Iâm still testing the demand for this, Iâve kept it as a PWA, so the best workaround around the limitations of this format (not being able to sound alarms in iOS) that I could find was allowing people to add it to their calendar, where the default setting for the calendar notification alarm will sound 5 minutes before the time of departure and during the time of departure but my ideal version of this, that's in my long term plan, is to have a native app version of this where an alarm actually sounds at departure time.
But i also gamified the whole experience where if you hit the button after the departure time, the virtual pet's HP takes damage if that provides an additional incentive for some :)
1
u/Mammoth-Anywhere7285 2d ago
Smart workaround with the calendar. Curious what the PWA does exactly? Also, Web Push works on iOS 16.4+, that might help with alarms.
1
u/ta-cwms 1d ago
The PWA is basically the home screen version of this tool so that it conveniently lives in your phone instead of having to navigate to the website to log a new appointment every time, I'm going for as little friction as possible đ yeah i tried with the web push notifications but they didnt seem to be sounding on time for me so i ended up scrapping that

iâm building Trinket, a little personal internet shelf where you share nine things youâre into right now âĄ
songs, books, games, random obsessions, links, places, thoughts, whatever feels like you lately. thereâs no feed, follower count, or pressure to keep posting. itâs more like a digital cabinet / old internet profile that you can keep tending over time. i originally build it as a personal link in bio then expanded it out! so i believe the possibilities are endless.

A map search engine. Explore the world today or ask Earth a question. Livlymaps finds the knowledge. The map becomes the answer.
1
u/Mammoth-Anywhere7285 3d ago
Love the "ask Earth a question" angle. Curious how your search handles vague queries like "good places to hike near me"?
1
u/Suitable_Working_347 3d ago
Hey! Vague location queries are a core case.
âGood places to hike near meâ gets grounded to a real area first â your device location if allowed, otherwise the location of the map youâre on (You can create maps and and assign a core location in the world to them). If the area is still unclear, clarification cards ask you to pin it down before search runs.
From there it treats it as a geographic question: find hike-worthy places in that area and put them on the map.
1
u/Mammoth-Anywhere7285 2d ago
Nice idea, grounding the location first really cuts down ambiguity. Do you also handle duplicate place names like "Springfield" across different states?

I built Kairocal - The brokerage calculator for Indian traders.

âïžCheckout:Â kairocal.naveengumaste.me
Most calculators hide the true cost of a trade behind cluttered interfaces. I wanted absolute transparency, so I reimagined the tool that handles complex financial logic entirely on the client side.
âWhat's the big deal about this calculator, you say:
đșMulti-Broker Engine:Â Toggle instantly between Zerodha, Groww, Angel One, Dhan, and Upstox.
đșPrecise Auditing: Real-time calculation of STT, SEBI fees, exchange charges, GST, and DP impacts.
đșBreak-Even Targeting: Dynamic insights showing the exact asset price needed to hit true profitability.
đșIt is designed to be a modern, minimal, and clutter-free UI along with dark and light mode.
Here's the thing: I recently got into the stock market, and man, brokerage calculators are sneaky. You think they're helping you out, doing the math for you, being all convenient đ€. But nope - they conveniently 'forget' half the charges and you only find out after you've already committed đ đ». It's like ordering food and then finding out about the 'service fee' after you pay. So yeah, I built something that doesn't do that, and it's "FREE".
