Cognitive Memory for ChatGPT

Give ChatGPT a memory that actually lasts.

ChatGPT is brilliant, but it forgets what matters between chats. CogmemAi adds persistent, structured Cognitive Memory so your Ai remembers your preferences, your projects, and your decisions across every session. Top published score on LongMemEval. Free to start.

The problem

You explain yourself to ChatGPT again, and again, and again.

Built-in memory is a start, but it is limited and opaque. The context that matters, your stack, your style, the decisions you already made, keeps slipping away. CogmemAi gives ChatGPT memory you can see, edit, and rely on.

ChatGPT on its own

  • Re-explaining every chat. Your preferences, your project, your tone, restated from scratch.
  • Context that fades. Important details from last week are gone or fuzzy.
  • Memory you cannot inspect. Hard to see exactly what it kept or why.
  • Locked to one app. What it learns does not travel with you.

With CogmemAi Cognitive Memory

  • It remembers you. Preferences, decisions, and context carry across every session automatically.
  • Structured recall. Importance scoring and semantic search surface the right detail at the right moment.
  • Memory you control. View, edit, and delete any memory on your My Memories page.
  • Portable. The same memory works across ChatGPT, Claude, Gemini, and any MCP-compatible tool.

Frequently asked

ChatGPT memory, answered.

Can I add persistent memory to ChatGPT?

Yes. CogmemAi Cognitive Memory adds persistent, structured recall on top of ChatGPT. You chat through the HiFriendbot interface with your ChatGPT model, and CogmemAi remembers your preferences, decisions, and context across every session.

How is this different from ChatGPT's built-in memory?

CogmemAi adds structured recall, importance scoring, and semantic search that you can view, edit, and carry across tools. It scored 95.10% on LongMemEval, the field's hardest long-term-memory benchmark.

Do I need my own OpenAI API key?

No. You can bring your own OpenAI key (BYOK) to use your ChatGPT model directly, or use Quick Start, which is included so you can try Cognitive Memory with no key and no setup.

Does the same memory work with Claude and Gemini?

Yes. Your Cognitive Memory is portable. The same memory works across ChatGPT, Claude, Gemini, and any MCP-compatible tool, so switching models does not mean starting over.

Can developers connect CogmemAi to ChatGPT over MCP?

Yes. CogmemAi ships as an MCP server (cogmemai-mcp on npm), so where ChatGPT supports MCP connectors it can call CogmemAi's memory tools directly. Most people simply use the Cognitive Memory product, which needs no setup.

Is my data private?

Yes. Your memories and any API key are protected with quantum-safe encryption, never sold, and never used to train Ai models. You can view and delete any memory at any time.

Is it free?

Yes. CogmemAi Cognitive Memory has a free tier, so you can add memory to ChatGPT at no cost and upgrade only if you need higher limits.
