Brand Studio Agent: Your B2B Brand, by Voice

Founders do not fail at video because editing is slow. They fail because nobody tells them the idea is weak before they spend an evening recording it. Faster tools only make a bad idea fail faster. Judgment is the scarce thing, and nothing automated wins without it. Brand Studio Agent is a companion that walks a B2B founder by the hand from "who am I on camera?" to a finished, captioned video built to sell. Brandy, a voice agent on the AssemblyAI Voice Agent API (WebSocket audio, barge-in, JSON-schema tool calling), interviews the founder and writes a Brand Soul in their own words, with a real quote behind every claim. A catalog of 30 ideas follows, each tied to a demand signal. Every script must pass 14 deterministic rules, no LLM, before it can be locked. Takes are transcribed by AssemblyAI with word-level timestamps, and an FFmpeg service on Cloud Run renders the final MP4. Agentic Mode removes the friction: the founder can drive every step by voice, iterate a scene by talking, and Brandy only runs a paid action after an explicit spoken confirmation that our code checks, not the model. Every action is logged in an audit trail. The result is a real personal brand, the founder's biggest asset for their business and their life.
