What is Central Brain AI?

How does Central Brain AI work?

Central Brain by NeuroAIgent is a local-first AI memory layer for the AI tools you already use. The desktop app for Windows and Apple silicon Macs prepares and indexes project files on storage you choose, using a bundled 384-dimension MiniLM embedding model and a local index, and serves project memory and source-traceable search to supported AI tools over the Model Context Protocol (MCP). Selected files, prepared content, metadata and project context persist across conversations. Precise intake, Quick Add, background schedules, inventories and optional local redaction support project control. Share Brain uses explicit project permissions; encrypted portable copies exclude private profile keys and provider credentials. Fleet Mode is a separate Preview for supported document preparation, with indexing and embeddings kept on the owner. Memory is kept as readable local files: five note types (decision, fact, question, todo and summary) plus a project brief. Licensing uses Keygen; connected AI tools receive the context they retrieve, and optional cloud connections send selected data only when you enable them. 14-day free trial. No credit card required.

Memory. Five note types (decision, fact, question, todo and summary) plus a project brief, stored as readable local files.

MCP tools. Standard MCP tools. Source-file tools are read-only; memory_checkpoint appends notes; memory_compact replaces the project brief and marks older notes as compacted rather than deleting them. On connect, central_brain_ping returns a RESUME block from the project’s saved memory, so a new session picks up where the last one left off.

Which AI tools work with Central Brain AI?

Claude Desktop, Claude Code, GPT Desktop, GitHub Copilot in VS Code, Hermes and OpenClaw, connected over standard MCP with a configuration the app generates for each client.

For setup steps, see the MCP memory server guide.

What stays on your computer?

In the default workflow, files, prepared output, vectors and memory stay on storage you choose. Keygen receives licensing and device data, not documents. Connected AI tools receive the context they retrieve. Explicit sharing exposes approved projects to trusted computers; Fleet Mode workers receive the inputs needed for assigned tasks. Optional cloud connections send selected data only when enabled.

Central Brain runs air-gapped: preparing files, indexing, search and memory need no network connection. The license is re-checked online every 14 days, and Team and Enterprise plans can get a build with no online license check. Optional cloud connections and cloud-hosted AI clients need internet.

What does Central Brain AI index?

Central Brain prepares and indexes PDF, DOCX, TXT, Markdown, CSV and XLSX, with metadata-only indexing for images, audio and video; OCR is optional and depends on the build.

Source traceability. Results include the source path, prepared-file path, page and chunk where available.

Embeddings. A bundled 384-dimension MiniLM model and a local JSONL index; cloud embeddings are optional.

Is Central Brain AI related to the “central brain” in neuroscience?

No. Central Brain is NeuroAIgent's desktop AI memory software, not a chatbot. It is unrelated to the anatomical central brain and the Central Brain Tumor Registry of the United States, and is not affiliated with other projects, products or services that share the name.

How does Central Brain AI compare with other AI memory tools?

Central Brain is a local-first AI memory layer: it keeps memory on storage you choose and serves it to several supported AI tools over MCP, instead of keeping memory inside one assistant or inside a service that developers connect to their own applications.

These categories overlap, and products change. Compare the data boundary, the supported clients, how you inspect and correct memory, and what needs a network connection, rather than the word “memory” alone. The AI memory guide explains the category in more depth.
