# PersistMemory

> A memory layer for AI applications. It captures conversations and documents,
> extracts durable memories from them, and retrieves those memories across
> assistants through MCP, an HTTP API, and first-party SDKs.

## What it does

- Captures from Gmail, Google Drive, Google Meet, Slack, Microsoft Teams and
  WhatsApp, or directly from an assistant over MCP.
- Extracts decisions, tasks, commitments, reminders and the people involved,
  rather than storing a transcript to search later.
- Supersedes a memory when something changes instead of overwriting it, so the
  earlier state is still answerable.
- Scopes memories to Spaces, so a question scoped to one Space never returns
  another's.
- Surfaces conflicts when two sources disagree rather than silently ranking one.
