ChainMemory — Portable AI Memory

Save and reuse your AI memory across ChatGPT, Claude, Gemini and Perplexity. Portable, verifiable, owned by you.

Your AI forgets everything when you close the tab. ChainMemory fixes that. ChainMemory is a portable, verifiable memory layer for AI. Save important decisions, context and learnings from any AI chat — and bring them back into any other model, anytime. What you can do: • Save memories with one click from ChatGPT, Claude, Gemini or Perplexity • Inject the right context into a new conversation — no copy-paste • Keep a consolidated "Project Brain": your decisions, milestones and risks in one structured view • Verify your knowledge cryptographically — each memory and project state has a hash anchored on a public blockchain • Own your data: it lives in your account, portable across every model, with no vendor lock-in How it works: Connect your ChainMemory account (free), have a normal conversation, and save what matters with the floating button. When you start a new chat — with any model — inject the context you need. Your memory follows you, not the vendor. ChainMemory is built for people who work across multiple AIs and need their knowledge to be persistent, portable and provable. Learn more: https://chainmemory.ai · Docs: https://docs.chainmemory.ai
