What is Living Brain?

Living Brain is a memory layer for agentic AI. It captures the knowledge in your AI conversations, connects it to what you already know and keeps it as a persistent memory that keeps evolving. You can share that memory across AI models, apps and agents through an API, SDK or MCP. A new chat in ChatGPT, Claude, Gemini, Cursor or Codex can then build on earlier ones.

How much does Living Brain cost in 2026?

Pricing for Living Brain is not publicly available in the data reviewed. No plan names, amounts or billing periods are listed, so no figure is given here. Before you budget for it, check the official site and confirm whether cost depends on memory size, API calls or the number of connected agents, since early terms may have changed.

Is Living Brain free?

A free tier is not verified for Living Brain. The available data lists no free plan, trial or usage limits, and it lists no paid plans either. Check the official site to see what you can try before you connect your AI tools, and confirm what happens to stored memory if you stop using it.

Living Brain vs alternatives in this category: what is the difference?

Its stated difference is portability. Living Brain describes one memory that you reuse across many models and tools, including ChatGPT, Claude, Gemini, Cursor and Codex, through an API, SDK or MCP. Many memory features in this category sit inside a single chat app and stay there. Accuracy, storage limits and price against other options are not verified, so this comparison is based on publicly available information only.

What are the best alternatives to Living Brain?

No specific alternatives appear in the available data, and any competitor list is not verified, so none are named here. When you compare options, look at memory layers built for AI agents, the memory features inside individual chat assistants and note-taking tools that store AI output. Check how each one shares memory across models and whether it supports MCP.

Is Living Brain safe for general business use?

Living Brain may suit general business use, based on publicly available information, but its security details are not verified. The product stores knowledge from your AI conversations, which can include client data, plans or code. Encryption, access controls, data location and certifications are not listed. Ask the team about these and about deleting stored memory before you connect work accounts.

Does Living Brain have an API?

Not verified: API availability is not publicly verified for Living Brain. Buyers should not assume a usable public API exists until the vendor publishes developer documentation or confirms access directly. Before planning an integration, verify endpoints, authentication, rate limits, pricing, support terms, and whether API access is generally available or limited to partners.

How does Living Brain work?

Based on publicly available information, Living Brain captures knowledge from your AI conversations, links each new item to what you have already stored and keeps the result as an evolving memory. Your tools then read that memory through an API, SDK or MCP, so a new session starts with context instead of from zero. How it extracts and ranks knowledge is not verified.

What does Living Brain do?

It gives your AI tools a shared, lasting memory. Knowledge from past chats is captured, connected to what you already know and made available to other models, apps and agents. The listed tools include ChatGPT, Claude, Gemini, OpenClaw, Hermes, Cursor and Codex. You stop repeating the same background to every assistant, and each new interaction can build on the last one.

Does Living Brain train on user data?

Whether Living Brain trains models on your data is not publicly available. The data reviewed has no training policy, retention period or deletion terms. Since the product exists to store your conversation knowledge, read its privacy policy and ask how stored memory is used before you send it sensitive work, personal details or client information.

Adds persistent user memory to a custom agent through the SDK
Compiles project files and meeting notes into a source-linked knowledge base
Connects memory to a custom MCP server so internal agents share one context
Developers building AI agents who need memory that carries across sessions, because Living Brain stores knowledge and serves it through an API, SDK and MCP
People who work across ChatGPT, Claude, Gemini and Cursor who need their context to follow them, because the same memory is shared across compatible AI tools

HOW WE VERIFY

Mindber only surfaces numbers that trace to a linked source record or explicit feature provenance. When the evidence is thin, the page hides the field instead of guessing. Activity and fit summaries reuse the same approved projections across the hero, main panels, and sidebar so one product cannot show two different truths.
