Living Brain

Key facts: Living Brain is a persistent and self-learning interoperable memory layer: one Living Brain for every AI, compatible with 60+ AI platforms and available in-app and via API, SDK and MCP. It compiles scattered conversations, files and updates into structured, source-linked knowledge, so your agents remember more with less context. On its own internal evaluations it reports 92.2% judged accuracy on LoCoMo across 1,540 questions, 464 ms median memory retrieval, and 95% lower cost per task than full context.

Plans: Pay as you go: top up from $5, with no monthly minimum. Model pricing is $8 per 1M input tokens and $0.50 per 1M output tokens. Some plans include $80 in shared monthly credits for 3 cycles, then $50.

Best for: Builders whose agents keep forgetting everything between sessions. Who should skip it: anyone whose AI use is one chat at a time with no memory to keep.
