# MemoryBridge AI

> A private memory layer that ChatGPT, Claude, Cursor, Claude Code, and other
> AI assistants share. You save something once and every connected assistant
> can recall it, instead of you re-explaining your projects, preferences, and
> context at the start of each conversation.

MemoryBridge AI is operated by Apex Leadership Lab, LLC (Delaware LLC, San
Francisco, CA). The service is available to United States residents only at
present; marketing and signup pages are geofenced, and account creation
currently requires an invite code.

## How it works

- Connect an assistant over the Model Context Protocol at
  `https://memorybridge.ai/mcp`, authenticated with OAuth 2.0 or an API key.
  Six tools are exposed: search, fetch, create, update, delete, and extract.
- Assistants search your memories and add new ones. Anything extracted from a
  conversation lands in a review inbox as pending, so nothing is stored
  without your approval.
- A REST API covers the same ground for tools that don't speak MCP.
- A Chrome extension saves selections or whole pages from the browser.
- "Ask your memory" is a chat surface over your own memories, with citations.

## Privacy posture

- Memories are never used to train AI models, by us or by our providers.
- Content is scrubbed for secrets (API keys, card numbers, SSNs, private keys)
  before storage and before embedding. Strict mode refuses such writes outright.
- Row-level security isolates every account; API keys are stored SHA-256 hashed.
- Export as JSON or Markdown, or delete your account and all data, at any time
  and without contacting support.

## Plans

- Free: 100 stored memories, 30-day retention, 20 AI queries per month.
- Pro: $12 per month or $108 per year. 25,000 memories, unlimited retention,
  400 AI queries per month, premium model.

## Notes for AI agents

- The MCP endpoint is `https://memorybridge.ai/mcp` and is the only one; there
  are no per-client variants.
- OAuth discovery follows RFC 9728 and RFC 8414 at
  `/.well-known/oauth-protected-resource` and
  `/.well-known/oauth-authorization-server`.
- Self-registered clients receive `read:traces` and `write:traces`. Destructive
  and key-management scopes are granted only from the account dashboard.
