One shared memory for all your AIs, built mostly by Claude Code: tell one agent once and ChatGPT, Claude and Claude Code all remember.
Every AI you talk to starts from zero. mazkir is a shared memory layer that fixes that: tell one AI something once, and it shows up in your next chat — in Claude, Claude Code, and ChatGPT. It's a remote MCP server; your memory is plain Markdown notes you can read, edit, export, and delete, with per-project permissions.
The feature list is practical rather than flashy: 20 MCP tools, OAuth login, a 30-day trash bin in case an agent deletes something, dark mode. Free during early access.
The author's showcase post is disarmingly honest about how it was made: "claude code built most of it for me." Launch week brought ~160 visitors and exactly one sign-up — the author's friend. The numbers are real; so is the product.
