84,000 Stars: What MiroFish Actually Does

Comment "STARTUP" and I'll send you the link. MiroFish is an open source simulation engine with 84,000 stars on GitHub. You give it a document and a question. It reads the document, builds AI characters with their own personas, and lets them post and argue on two simulated platforms. Then it writes a report, and you can chat with the characters. Here's the honest part. The repo never pitches this for startups. Using it on your idea is your own experiment. These people aren't real and they aren't customers. The project's own FAQ says to treat results as "simulated hypotheses". So rehearse with it. Then go talk to real customers. It posts nothing to real social media. It needs an LLM key and a Zep key, it can get costly, and it opens in Chinese with an English switch. The product screens in this video are from the project's own demo. The crowd and the town are my drawings. I didn't run it for this video.
