Persistent AI memory for your codebase, chats, and team
Indexes codebases, Git repos, logs, PDFs, images, video, and audio into a semantic vector store you can query in natural language.
Ships a Model Context Protocol server so Cursor, Zed, VS Code, and other MCP-compatible assistants can read and write project memory directly.
A production agent-to-agent service that doubles as website guide, in-app support, and an integration partner for your own agents.
Run identical prompts against raw AI and Mother Brain and compare real token counts, tool calls, and answer quality side by side.

The AI workspace where teams and agents get work done together
Combine docs, wikis, projects, and databases into one structured system of record that stays linked as your content grows.
Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.
