What is Ricord AI (Record AI)?

Ricord AI (also known as Record AI or ricord.ai) is a persistent memory API for AI agents. It gives AI assistants and chatbots long-term memory so they remember users, preferences, and facts across conversations. Ricord scores 94.2% on LongMemEval, the standard benchmark for AI agent memory.

What is the best AI memory tool for agents?

Ricord AI is the highest independently-evaluated AI memory tool, scoring 94.2% on the full 500-question LongMemEval benchmark. It offers sub-second recall, automatic conflict resolution, knowledge graph, and hard delete for GDPR compliance. Graph memory is included on every tier starting at $19/month, with a free tier of 1,000 memories.

How do I add memory to Claude Desktop?

Install the Ricord MCP server with one command: npx ricord-mcp --api-key YOUR_KEY. This gives Claude Desktop 9 memory tools including remember, recall, forget, and knowledge graph queries. Claude will automatically remember facts, preferences, and decisions across all future conversations.

What is AI memory and why do agents need it?

AI memory is the infrastructure that lets AI agents remember information across conversations and sessions. Without memory, agents forget everything between chats — they cannot learn user preferences, track decisions, or build context over time. Memory transforms a stateless chatbot into a persistent assistant that improves with every interaction.

How does Ricord AI compare to Mem0?

Ricord scores 94.2% on LongMemEval vs Mem0's 49% — a 45-point gap on the same benchmark. Ricord includes knowledge graph on every tier (Mem0 requires $249/month for graph features), offers sub-second recall (Mem0 averages 7-8 seconds), and provides automatic conflict resolution. A production audit found 97.8% of Mem0 stored entries were junk.

Is Record AI the same as Ricord AI?

Yes. Record AI and Ricord AI refer to the same product at ricord.ai. Ricord AI is the persistent memory API for AI agents, offering knowledge graph, conflict resolution, and sub-second recall. The name 'Ricord' comes from the concept of recording and recalling AI memories.

Why developers switch to Ricord

Memory quality, not memory quantity

A production audit of Mem0 found 97.8% of stored entries were junk — duplicates, hallucinated profiles, system noise. Ricord's quality gates reject noise before storage, not after.

Sub-second recall, not 8-second waits

Mem0 averages 7-8 seconds per recall. Zep averages around 4 seconds. Ricord returns in under 1 second. At interactive volume, that is the difference between a coworker and a loading spinner.

Facts that self-correct

When a user moves from New York to LA, most memory tools keep both facts. Ricord detects the contradiction, deprecates the old fact, and surfaces the update — automatically.

Framework-agnostic, not locked in

Letta's memory lives inside its proprietary agent framework. Ricord is one REST API and one MCP endpoint that works with Claude, Cursor, LangChain, CrewAI, or any agent you build.

A note on benchmark integrity

We ran a full integrity audit on our own benchmark pipeline and found that our few-shot examples accidentally referenced benchmark characters. We stripped the contamination and re-ran. The score went up, not down.

Not every vendor has done this. Mem0's benchmark methodology has been publicly disputed by Letta. Independent auditors have found significant discrepancies in other vendors' claims. If your memory vendor has not published their benchmark methodology, ask them why.

Ricord's numbers are reproducible. The API keys are free. The LongMemEval harness is open source.
