by Mem0 AI

Pros

• ✓Every generated answer carries inline citations to the customer's own sources, and it is designed to say it does not know when those sources do not cover a question.
• ✓One knowledge base serves the Retrieval API, a hosted MCP server and pre-built agents for a website widget, Slack, Discord, a support form, Zendesk and in-product use.
• ✓Ingests more than 20 source types, from documentation sites, GitHub and OpenAPI specs to Zendesk tickets, Confluence and Notion, with continuous sync on paid plans.

Limitations

• ⚠Growth and Enterprise are quote-only, commercial plans carry a minimum annual commitment, and there is no self-serve card signup.
• ⚠Private sources, continuous sync, zero data retention and PII masking start on Growth, and SSO, SCIM, role-based access control and EU hosting are Enterprise features.
• ⚠The hosted MCP search tool returns results in about 3 seconds at the median and 4.5 seconds at the 95th percentile, and public OAuth servers allow 600 searches per user per day.

Pros

• ✓Mem0 runs as a managed platform or as Apache 2.0 open-source software, with Python and TypeScript SDKs, a CLI, a hosted MCP server and more than 20 supported vector databases.
• ✓On its managed platform Mem0 reports 92.5 on LoCoMo and 94.4 on LongMemEval for its April 2026 algorithm, using under 7,000 tokens per retrieval call.
• ✓Every plan, including the permanently free Hobby plan, allows unlimited end users, and the GitHub repository has 65.7k stars.

Limitations

• ⚠Graph memory, Dream memory consolidation and analytics start at the $249/month Pro plan, Starter includes one project, and on-premise deployment, SSO and audit logs require Enterprise.
• ⚠Content from Hobby plan users may be used to train Mem0's AI models, while Paid Plan data is excluded from training.
• ⚠The Trust Center lists a SOC 2 Type 1 report and a HIPAA self-attestation, both available on request, rather than a SOC 2 Type II report.
