Agentage

About Agentage

Agentage is a shared markdown memory layer that every AI tool you use can read and write through a single MCP endpoint. It targets a specific tax on multi-tool AI work: if you move between Claude, ChatGPT, Cursor and Claude Code during a day, each one opens with no idea what the others already know, so you become the memory layer — re-pasting the architecture, the decisions and the constraints several times a day, indefinitely. Agentage replaces that with one memory you own, connected once per tool with a standard MCP command; signing in on first connect creates the account, so there is no separate onboarding flow. The storage format is plain markdown files rather than an opaque vendor store, which is the design decision that makes the product credible: you can read the memory without the product, export it at any time, and you are not exposed to a vendor deprecating its own memory feature and taking your context with it. Hosting is in the EU, which matters for teams with data-residency requirements. Setup is documented for Claude Code, Claude.ai, VS Code, Cursor and ChatGPT, and the project publishes docs, a blog and a public catalog alongside a GitHub presence.
