Score your social media posts on 312 factors before publishing.

I built an AI that scores your social post on 312 factors before you publish — roast my roaster Two of us are creators who got tired of the post-and-pray cycle: hours on a post, hit publish, hope, mostly flop, never know why. We realized the difference between our good and bad posts was never luck — it was hook, CTA, timing, caption. Fixable things. So we built Synthiya: paste a draft, pick your platform, and it grades it 0–100 across 13 categories (312 factors) and tells you exactly what t

Draw the same secret prompt as your friends, then let an AI roast your drawings.

Doodle Judge — built a game where an AI roasts your drawings, solo project Everyone in the room draws the same secret prompt under a timer. An AI (Claude Haiku) judges every drawing on a different criteria each round. The AI might roast you if you're not the best doodler. Built it solo. React/Tailwind frontend, FastAPI backend, deployed on Railway. Play with friends via a room code, or try it solo first to see how it works. No sign-up beyond picking a name. Would love any feedback or im

Play a strategy game about the AI race where you govern the US or China through 2030.
micstradev · HN
I made a strategy game where you play the US or China through the AI race, 2026 to 2030, sixteen quarterly turns in the browser. One run takes about half an hour. At the start, the game seals two dice you never get to see. Inside: how hard alignment really is, and how fast takeoff compounds. You get eval reports, but only as ranges, and they flatter you most exactly when your systems are least aligned. At the end you get a debrief which shows what your evals said each quarter and also what was actually true. I lost every run I played myself so far. Every number in the game is source-backed or a labeled design choice. Some of them are wrong somewhere. There is an issue template for challenging a number with a better source, and the better source wins. No accounts, no tracking, no server, works offline after first load. AGPL, nonprofit. Cards and parameters are plain JSON. Contribution is possible without writing code. Would like to have your thoughts if it is fun to play, how you lik

Ask one question to multiple AI models, compare answers, and watch them debate to consensus.

I kept pasting the same question into ChatGPT, Claude, and Gemini in three tabs; so I built a Yes-Brainer — a council of AI models, that answer your question in parallel, debate to consensus, or get judged to a verdict. submitted by /u/trekhleb to r/SideProject [link] [comments]
