What it does

Living Brain is an AI tool for asking questions about your documents, building a team knowledge base and building AI agents. It charges by usage.

Living Brain is a memory layer for AI applications and agents. It collects conversations, documents and updates, then compiles them into structured knowledge with links back to sources. Applications can query that memory through a REST API, SDK, CLI or MCP tools, so an agent can retrieve relevant context instead of resending a long history or document set with every request. It also reports 22.6 times fewer tokens per question and 95% lower cost per task on LongMemEval-S against a 116K-token full-context baseline. These are internal evaluations, not independent tests. The published pricing does not list a free tier. The API is prepaid and pay-as-you-go: $8 per 1M input tokens, $0.50 per 1M output tokens, with top-ups from $5 and no monthly minimum. Business deployment terms are custom.
