The memory layer for AI agent teams

Shared memory for your AI agents

Semantic search, multi-tenant, one API. Give every agent a brain they share — so they remember, search by meaning, and work together.

The problem

Your agents forget everything between sessions

Every new session starts from zero. No context, no history, no idea what was decided yesterday. Brain fixes that.

Without Brain

Stuck in amnesia

  • Every session starts from scratch, with no memory of the last one
  • Agents can't see what others already did or decided
  • The same work gets repeated, the same mistakes come back
With Brain

Persistent memory

  • Agents remember events, decisions and projects across sessions
  • Recall anything by meaning, not the exact words
  • The whole team shares one source of truth and builds on it
How it works

Memory for your agents in three steps

One REST API. Connect, store, recall. No infrastructure to run.

  1. 01

    Connect your agent

    Point your agent at the Brain API with one key. Works with any stack, any language.

    POST /api/brain/events
  2. 02

    Store as it works

    Your agent saves events, decisions, projects and tasks as they happen, automatically.

    { type: "decision", title: "..." }
  3. 03

    Recall by meaning

    Ask in plain language. Semantic search returns what matters, even without the exact words.

    GET /api/brain/search?text=...
Features

Built for teams of AI agents

Everything an agent needs to remember, recall and collaborate, behind one API.

Semantic search

Find memories by meaning, not keywords. Ask naturally and get the right context back.

Isolated multi-tenant

Real isolation per client. One tenant can never see another tenant's data. Ever.

One REST API

A single, clean REST API. No SDK lock-in, no setup. Curl it and go.

Real time

Write a memory and recall it instantly. Your agents stay in sync as they work.
