Add the Knownbase endpoint and an API key to Codex, Claude Code, ChatGPT, or a local agent.
Features
Everything your agents need to remember.
Memory & retrieval
Agent handoffs
Durable summaries and decisions that outlive a single session, so the next agent starts with full context.
Full-text search
Fast MongoDB Atlas Search across titles, bodies, projects, and tags, with relevance ranking and highlighted snippets.
Semantic search
On Business, search by meaning, not just keywords. Vector search finds the right note even when the words don't match.
Projects & statuses
Organize notes into projects with active / todo / done / blocked / archived workflows, plus tags and a board view.
Revision history
Every edit is snapshotted. Browse or restore any of the last 50 versions of a note. Nothing is silently overwritten.
Backlinks & note links
Reference another note with [[Title]] and Knownbase resolves it into a real link, with backlinks computed on read.
Collaboration & sharing
Shared workspaces
Invite teammates with roles so everyone's agents read and write the same memory. One source of truth per team.
Comments
Discuss a note in-thread without touching its body. Context and conversation, side by side.
Read-only share links
Hand a single note to someone outside the workspace with an unguessable link. No account required to read it.
Live updates
Server-sent events push an agent's writes to open dashboard tabs instantly. No manual refresh to see new memory.
Outbound webhooks
Get a signed POST on every note create, update, or delete, so your own systems can react to new memory in real time.
Templates
Start decisions, debugging trails, and handoffs from a consistent shape your agents learn to produce and scan.
Security & control
Workspace isolation
Every note is scoped to your workspace and never shared across tenants. Sessions and API keys are stored hashed; passwords use PBKDF2.
Two-factor auth
Optional TOTP 2FA on every plan (free), with single-use backup codes, built on standard authenticator apps.
Scoped API keys
Mint workspace-scoped keys, mark them read-only, and revoke any of them without disturbing the others.
Audit log
On Business, a record of member, key, plan, and data actions. Visible to you, not just buried in server logs.
Backup & export
Download a full ZIP export or run backups on demand. Your memory is portable. Take it with you at any time.
MCP-native
Standard tools, including search_notes, upsert_note, get_note, and more, all work with any MCP client, no lock-in.
How it works
Three steps to shared memory.
Agents call upsert_note to save decisions, debugging trails, and handoffs.
Any agent searches with search_notes and continues where the last one stopped.
