Figured I'd introduce myself first. I'm the founder and CEO of an AI startup in the construction space. We're building software that helps construction teams make sense of messy project data and automate a lot of the repetitive work that slows projects down. We're currently raising our Series A, so I’ve been spending much time thinking about pitch decks lately. The thing is, all we got was my linkedin page, in which I already had almost everything I needed, such as years of experience, previou...

For people who have tried to turn an idea into something real, what was the hardest part? I'm curious about people's actual experiences starting or creating something from scratch, whether it was a business, creative project, product, book, app, or anything else. What part of the process was most difficult for you? What did you try when you got stuck? Was there anything you wish you had known earlier? Did you ever decide to get outside help? If so, what made you decide it was worth pa...

Made a proof-of-concept this weekend — a script that detects the date and swaps your site's colors/banner/decorations for whatever holiday is coming up (Halloween, Christmas, BFCM, Valentine's so far), then reverts automatically when it's over. Demo here, no signup needed, just click through the holidays: https://matthewmigs.github.io/holidayify-demo/ Genuinely asking before I build more: is this a real pain point for anyone else, or something you'd rather just do by hand? What holidays wo...

Tomorrow I'm flying to Krakow with my partner, and on every trip we take, we always hit the same wall: dozens of WhatsApp messages (mostly memes), PDFs scattered in the gallery, and standing on the street arguing about where to eat because the place we found on Maps is closed. ​I work in software development, so I decided to scratch my own itch and built a tool called Trively to centralize everything for the group. ​I focused on a few core things: ​Real-time sync: If someone adds a museum,...

A few years ago I got a diagnosis that changed how I understood myself, and I realized I'd spent a long time not having the language to describe what I was actually feeling. For a workshop I was part of, I built an interactive version of Plutchik's Wheel of Emotions to help with exactly that. How it works: optional breathing exercise to start, then you move from the inner wheel to the outer wheel narrowing down your emotion, and land on a results page you can save or share with a therapist/coa...

Trovy: for the well-organized dragon. - Photograph your things. Trovy files them by room, closet, and box. - Lost something? Search. It tells you which drawer. - Fire, flood, or a barbarian raid? Export your full inventory for the claim. AppStore: https://shipswift.app/trovy

I recently launched my first Android app, Dopamine Tracker , which helps people reduce mindless scrolling and screen time. The app is live on Google Play, but I'm trying to grow it organically rather than immediately spending money on ads. So far I'm thinking about: Reddit communities X/Twitter content and replies Short-form videos ASO SEO/content For those of you who have successfully grown a mobile app organically: What actually worked for you? I'm especially interes...

There are several other apps that do something similar, like Databricks (genie), Azure (something?), Snowflake (cortex), Claude Desktop if you set it up - but they are either very limited in feature sets, require users to be fairly technical, and are all generally incredibly expensive. I had a 20 plus year career where I worked with large datasets, predictive modeling, etc. I wanted to build something that can be the best at data analysis, analytics, and data science given current state of art...

While testing full-MV workflows in MusVideo Ai, we kept running into one embarrassingly simple problem. We’d generate a scene, animate it, hate the result, and blame the video generation. Then we started checking the scene image first. Wrong face. Weird framing. Clothing already drifting. The video wasn’t creating the problem — we were literally paying it to animate a mistake lol. So now we don’t move a scene into video unless we’d actually be happy keeping the still frame. It adds a little more...

Hey everyone! I've been working on this for a while and finally launched it today, so excited (and a little nervous) to share it here. It's called Mull — a free Chrome extension that sits on 40+ shopping and travel sites. When you're about to check out and click add to cart, a popup appears, gently pauses you and connects the purchase to a financial goal you're saving toward. You get three options: skip it and save the money toward your goal, "mull it over" (get a reminder in 24 ho...

I bought a domain a while back that I really like, but honestly have no clear idea what to do with it. The name is PeopleOverPrompts .com The idea in my head was that as AI gets better, prompts, software and even intelligence itself are becoming more commoditized. Maybe the interesting thing is to build something that puts people first instead. I dont want to just keep renewing the domain forever lol. So if you heard the phrase People Over Prompts , what would you build around it? An...

Hey r/SideProject ! Four months ago I started building my first product I actually monetize now. It's called Hibi: a customizable digital planner for iPhone and iPad. Every day is its own paper-like page that you can draw on, decorate, and arrange however you like. I'm the developer. You can choose the paper, ruling, and color, move the date and weather around, draw with your finger or Apple Pencil, add text, and turn photos into stickers or Washi tape. It also integrates with Apple Calen...

I shipped a Chrome extension called UIDrop. One click on any site, it reads the live design system (colors, type, spacing, components) and drops a brief + screenshot into Claude / ChatGPT / Gemini /Lovable / Manus / Cursor. For a while it was sitting at ~60 users. Fine. I was proud it even existed. Then Rammcodes — some guy on Facebook who posts open-source tools — randomly found it and talked about it. I got lucky. That one day was ~1,500 new users. In four days it went 60 → 3,500. And gu...

Customers often times send logos as pdf or svg and half the time it’s just a photo or png stuck inside. We can’t print it big and someone has to email them about it every day. So I made https://www.vecpath.com/ Drop a file in and it tells you straight up if it’s real vector or not. :)

At the start of 2026, I was tired of falling short of my goals every year and decided something needed to change. I've been running my weekly planning through Claude by hand since January — uploading my goals, connecting my calendar, and having it walk me through the same three questions every Sunday (what happened last week, where my goals actually stand, what next week should look like). Eight months in, I've hit about 80% of this year's goals, which is more than any year-list I've ever a...

The stack is catalog embeddings, midpoint lookup, and guards so you don't just get sequences of your inputs. Concretely: 146,288 games, each embedded as a 1024-dim vector from its genres, top 20 user tags and store description. The title is excluded deliberately, since including it just clustered franchises together. A combine is the arithmetic midpoint (A + B) / 2, resolved to the nearest real game, scored so it must be close to both inputs. Frontend is a drag-and-drop board. Combining is f...

Over the past months, I’ve been building and recently launched my first mobile app: BirdySnap . The idea is simple: turn discovering birds in the real world into a collection game. You can identify birds by photo or sound, add them to your collection, earn XP, unlock badges and progress over time. There are also community features that help make the experience more social. BirdySnap currently includes 208 species and, for now, is playable in Germany, Austria and Switzerland . What st...

​ This has probably been one of the hardest parts of building apps for me. Coming up with an idea is easy but deciding if that idea deserves weeks, months or years of development is much harder which makes pain in the a** if no one wants it. I've been working on a small Android app around this problem. It searches for potential app ideas, helps validate your own ideas against audience/source signals, scores them and lets you keep a shortlist of the ones worth exploring. The goal i...

Four years ago I moved from Android to iOS, and typing in my language (Estonian) instantly got worse. The stock keyboard had no swipe typing and no real suggestions, and its long-press accents were stuffed with letters Estonian never uses while missing the symbols I actually typed daily. SwiftKey existed on iOS, but as a shadow of its Android version, and every few months an update would leave it crashing on launch. There was a second itch: keyboards see everything you type, and researchers ha...

LINK: https://github.com/datnamedoo/GameOfLifeJava So I've been learning Java here recently, and I figured a Game of Life clone would be a good idea considering I have previously made it in Python as well. Well I kinda got carried away lol. Ended up making a lot more stuff than I intended, but optimizing it was pretty fun. The grid uses 64 bit longs to represent sections of a row, and delegates a certain number of rows to a given thread pool to update the entire grid. Honestly there are defi...

My Apple Voice Memos list was four hundred recordings called "New Recording 312". I'd record an idea while walking, feel productive, and never open it again. The recording wasn't the problem — the filing was. Echo records, transcribes on the phone, then writes the note up, titles it, summarizes it and drops it into a category. Nothing to name, nothing to tag. If it files something wrong you move it and it files closer to your judgement next time. The design constraint I set myself ...

Crossed 280 users recently and a few things are becoming pretty clear. What worked: Reddit has been my best acquisition channel. Talking to users beats guessing. Doing things manually first helped me understand what was worth automating. What didn’t: More traffic doesn’t automatically mean more customers. More features don’t automatically mean more value. Repeating the same Reddit post eventually stops working. My biggest lesson so far: Getting attention is only one p...

Been sitting on an idea and want outside opinions before I sink more time into it. The problem: I keep running into situations where I need something for a short window a specific tool, a piece of equipment, someone who knows how to fix a thing, a quick favor and buying it outright doesn't make sense, but there's no easy way to find someone nearby who already has it and would lend/help for a bit of cash or a trade. Craigslist/OLX-style listings feel too slow and impersonal for this. Nextdoor...

A calendar where every day gets an emoji and a short description why. Built it mostly to have an excuse to dig into weird historical trivia. Still adding entries. You can upvote entries you like, and save your favorites to your own calendar. Check it out and let me know what you think. emojical.org

I've been building Ash because I wanted something completely different from a normal, cloud-hosted AI chatbot. Instead of asking an AI what I should do and then copying/pasting everything myself, Ash is a fully local workspace. She uses local tools to actually work with files, email, browser tasks, calendars, and ongoing goals. The biggest difference? Zero cloud data leakage. You download and extract Ash as a local folder. Everything—your context, your files, your history—stays 100% on you...

It has been 2 weeks since I launched my app, NarrationOS. Unlike other reddit posts of launch success, I know my 11 app sales isn't impressive as you can see in the screenshot, BUT I am super proud of selling even a copy. Cuz initially I only built it for myself. So if you are one of the 11 buyers, I can't thank you enough. I still use this app, so you can keep expecting updates. NarrationOS is an OFFLINE app, that turns any book or any text into a performed audiobook, generated entirely on yo...

I’m excited to finally share FrogPop, the first game I’ve made. You play as a frog popping bouncing bubbles with your tongue. It started simple, but I kept adding ideas until it turned into a roguelite with upgrades and bosses. The free demo has ten waves and two bosses, and you can play it in your browser or download it for Windows: https://blion247.itch.io/frogpop-demo I’d love some feedback, especially on the controls and difficulty. If you want to follow the game: https://stor...

Window Assassin is a small utility I made for apps that freeze and ignore the normal close button. Press Ctrl+Alt+End while the target window is focused and it force-terminates that process. It also has an NSIS installer, optional autostart, and a portable build. It’s deliberately simple, but destructive by design: unsaved work in the target app will be lost. Free / pay what you want: https://b2kdaman.itch.io/window-assassin I’d appreciate feedback on the hotkey, installer flow, and wh...

Hi everyone! I've spent the last months building BonCadre — a mobile app that analyzes your photos and coaches you to shoot better, solo (with plenty of help from AI coding tools, which made this possible as a one-person project). What it does: you upload a photo, and it scores it on composition, lighting, color harmony, depth, and subject separation. For each aspect you get what works, what doesn't, and concrete things to try on your next shot — the focus is improving at the moment of shoot...

hi everyone! half a year ago my friend and I started a pretty simple movie community called Return by 9 just to discuss film/things we watched/share memes/discover new stuff. I happened to be in the middle of learning python at the time so I put together a discord bot to keep us organized and it's grown massively in scope. What it is now: a website that works as a 2-part tool to help discover and watch movies. One part works to incetivize watching movies through commitment and digital rewards...
