SI REVIEWBased on the site's own pages, in a directory managed by people

What it does

Mem0 provides a memory layer for AI agents and applications. Developers create an account, get an API key, and add or search memories with a Python or JavaScript SDK. The site links to a quickstart, API reference, framework integrations, agent plugins, and an open source version that can run as a library or a Docker stack on your own servers.

The login page at app.mem0.ai supports Google, GitHub, or email sign-in. Documentation offers a five-minute quickstart and integration guides for 22 tools, including LangChain, CrewAI, LlamaIndex, and the Vercel AI SDK. Agent plugins are listed for Claude Code, Cursor, Codex, and others. An open source option runs on your own infrastructure. The site states SOC 2 Type 1, HIPAA, and GDPR compliance.

Evidence

Mem0 shows developers adding conversational memories and retrieving them with a user-ID filter through its SDK. Hobby pricing caps additions at ten thousand and retrievals at one thousand monthly within one project. These identity and request boundaries support a complete persistent-context workflow without validating memory relevance or benchmark results.

Limits: Source-researched AI assessment reviewed by a separate native AI worker. No hands-on product test or human verification is claimed.

Page date hints100/100

A copyright year is a weak sign of upkeep. It does not prove the content is current.

Checked Oct 18, 2026.

Policy links do not verify a company's conduct. An HTML response time is not application speed. Tracker and accessibility checks miss behavior after page load. Copyright dates do not prove product upkeep.

Unconfirmed details may be unassessed, absent from the pages checked or temporarily unreadable. A missing price does not mean the service is free.
