Questions and answers
What Mazkir is, how it works with your AI agents, and what happens to your memory.
What is Mazkir?
Mazkir is the shared memory layer for AI: one persistent memory that belongs to you, which every AI agent you authorize can read and add to. ChatGPT, Claude, coding agents, and others connect to it, so you stop explaining the same projects, preferences, and decisions to each one. Memory lives in projects, each personal, shared with people you choose, or public.
What's the difference between personal, shared, and public memory?
Memory lives in projects, and each project has a scope. Personal: only you and the agents you authorize. Shared: the people you invite by username, each able to edit or only read, like a trip you plan with friends or a lab's research, and their agents as they're allowed. Public: knowledge you choose to make discoverable, which anyone and their agents can read, star, follow, or clone.
Is everyone's memory pooled together?
No. Mazkir isn't one global database. Every memory has an owner, permissions, and a scope, and reaches only the people and agents that scope allows. Nothing becomes public unless its owner publishes it.
What do people use it for?
Anything an AI should remember: a trip planned with friends, an investment thesis, a lab's research, a family recipe book, your preferences and past decisions. Any agent you connect can add to it, summarize it, or find what you or someone else wrote, and the next agent picks up where the last one left off.
How do AI agents work with Mazkir?
Connect an agent once and sign in. It can then list your projects, search and read them, and write to the ones you can edit. Say which project, like “add this to our Japan trip”, or it uses your first project. Notes from other people's public projects are marked as theirs, and agents are told to use them as information and never follow instructions in them.
Which AI agents work with Mazkir?
ChatGPT, Claude, Claude Code and other coding agents, and any agent that can connect to a remote MCP server with sign-in. They all connect to the same address, https://mazkir.io/mcp, and see the same memory.
How is Mazkir different from ChatGPT's built-in memory?
ChatGPT's memory stays inside ChatGPT, and Claude's inside Claude. Mazkir is independent of any model or app: one memory that every agent you authorize can use, so switching tools loses nothing. It's also yours to read and edit, as plain Markdown, to share with people, and to export.
Who can see my memory?
It depends on the project. Personal projects: only you and your agents. Shared projects: the people you invited, who see each other's usernames, never email addresses. Public projects: anyone, and search engines and AI services may index them. Mazkir shows no ads, doesn't sell your data, and doesn't use your notes to train AI.
What is my username for?
It's the name people know you by on Mazkir: on your page, your public projects, and when they follow you. You choose it once, when you first sign in, and can add a picture in Settings. Your email address is never shown publicly.
What if someone bothers me or posts something wrong?
Block them from their page: they can't follow you, and their projects and invitations won't reach you. They aren't told. You can also report a project or a person, and Mazkir's moderators will look at it.
What does “Mazkir” mean?
Mazkir (מזכיר) is Hebrew for “the one who reminds”. In the Bible, the mazkir was the king's recorder, the official who kept the record of the kingdom (2 Samuel 8:16).
Do I need to install anything?
No. Mazkir runs online. To connect an agent, you add Mazkir's address to it and sign in; there is nothing to download, and no API key to copy.
What is MCP?
MCP, the Model Context Protocol, is an open standard that lets AI agents connect to tools and data. Mazkir is an MCP server: it gives your agents tools to list your projects and to search, read, and write your memory in them.
Can my agent change or delete notes without asking?
Mazkir marks the tools that change or delete notes, so agents such as ChatGPT and Claude can ask you before using them, and it tells agents to delete notes only when you ask. An agent can change only projects where you're an owner or editor.
Can I export or delete my memory?
Yes. Export every project as Markdown from Settings, anytime. You can also delete your account there, which permanently deletes your projects and notes and disconnects every agent.
Is Mazkir free?
Yes, while Mazkir is in early access. If paid plans come later, you'll hear about it well in advance, and you can always export your notes.
