Cinemind

● Cinemind is a tool YouTubers drop into their live streams as an OBS Browser Source: their viewers type choices in chat, Gemini 3.5 Flash reads thousands of natural-language messages every ~15 seconds — handling synonyms, negations, and trolls — and decides which pre-rendered scene plays next from a Google Cloud Storage vault, with three coordinated sub-agents making it work (a Director that picks the next clip with story-aware reasoning, a Live Tally classifier that updates vote bars every 3 seconds, and a Narrative Summarizer that maintains continuity across a branching DAG with reconvergence). FFmpeg seamlessly concatenates the chosen clips and pushes a continuous 1080p stream to YouTube Live's RTMP ingest; a Next.js dashboard renders the live tally, branch map, and Director's reasoning panel so the audience watches the AI direct in real time. Gemini also intelligently matches image fragments to comments — the predicted-pane composite layers a different per-story-node reaction overlay (cartoon meme generated by Higgsfield Kling 3.0, AI-cinematic b-roll generated by Seedance 2.0, or stock footage) that maps chat energy to animation, so "LETS GO" gets a triumphant cartoon, "💀" gets a Home-Alone-style scared meme, and "WAIT WHAT" gets shocked wide-eyes. Built on Gemini 3.5 Flash + Google Cloud Storage + YouTube Data API + Veo 3 + Higgsfield + FFmpeg, with three deploy modes (own broadcast, local HLS demo, embedded as a guest in another creator's stream via scripts/guest_mode.py), the system turns thousands of strangers into a single collective director — a broadcast-quality experience whose narrative bends to whoever's watching, achievable for the first time because Flash can classify ~5,000 messages and decide in under 2 seconds at fractions of a cent per call (~$0.06 per 10-minute segment), and shippable as a creator integration because the entire chat-read-and-decide pipeline runs on free-tier YouTube APIs against any public live broadcast without the creator installing anything.
