Plan-first AI app builder that writes a spec, gets sign-off, then builds and verifies a live product you own.
What it does
BrainGrid is an AI app-building platform that plans before it builds. A planning agent asks clarifying questions and writes a spec with acceptance criteria and a data model; after sign-off, a builder agent (or your own Claude Code/Cursor/Codex via MCP) builds it, verifies each criterion with evidence, and ships it live with hosting, auth and email.
