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.
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.
No engineering required. Sign up, connect or skip a key, and start chatting with memory that compounds.
Sign up at hifriendbot.com/memory. No credit card required to start on the free tier.
Add your own OpenAI key (BYOK) to use your ChatGPT model directly, or use the included Quick Start to try Cognitive Memory instantly with no key and no setup.
Talk as you normally would. CogmemAi extracts what matters, scores it by importance, and recalls it by meaning, so your Ai keeps getting to know you. Inspect everything on your My Memories page.
