Brainz

Brainz keeps a product's knowledge where people and AI agents can share it: features, user stories, specs, workflows, decisions, constraints, glossary terms and tasks, stored as linked markdown concepts in a vault. Connect Brainz and Claude can: - search the vault and open any concept together with the notes it links to; - walk the graph around a feature to see what depends on it, what constrains it and which decisions apply; - assemble a briefing on a topic, trimmed to a token budget, ready to hand to a coding agent or a teammate; - record knowledge: create or update a concept, link two concepts, or delete one that is wrong; - work the task pile: list open tasks, take one (which returns its briefing), create a task from a finding, and complete one with an outcome; - return the onboarding and sync playbooks for indexing a codebase into the vault, and run or configure the vault's consolidation sweep. You sign in with OAuth and pick the vaults to share on the consent screen. The connection reaches only those vaults: owners and editors get every tool, viewers get the read tools. Brainz cannot read your repository or files, and it never receives your conversation, only each tool call's arguments. Read tools change nothing, and tools that overwrite or delete data are marked destructive. Brainz is free. Sign up at https://brainz.brownmatter.ai with a magic link or GitHub.
