AI movie recommendation app that explains its suggestions for group viewing.
u/amaldito · Reddit
I built an AI movie recommendation app solo, would love feedback :) Spent the last few months building Ellucca, a film recommendation platform that uses AI to actually explain why it's suggesting something instead of just spitting out a list. Built it entirely solo using Claude Code and the Claude API.

Play a multiplayer strategy game where you run a corporation across the Solar System.

🚀 I'm building Solar Empire — a browser MMO strategy set in one seamless, living Solar System. And here's the twist: the entire prototype was pair-built with Claude Fable 5. The game. You run a private corporation. You start on Earth, where the geology is hidden — buying a hex IS the prospecting, so every claim is a gamble. Power plants feed mines, smelters feed factories, and a player-driven market ties it all together. Then you go to space. A rocket is assembled at your factory, rolls out to your spaceport pad, and launches — gravity-turn ascent, stage separation, the works. The Moon it flies to is actually moving: transfer windows change your fuel bill in real time, just like real orbital mechanics. The planets are real NASA/USGS maps. Weather is simulated once for everyone — the storm cutting your solar output is the same storm your rival sees from orbit. Abandoned bases decay into ruins that other players can scavenge, so the map never clogs up. The pro
