username.md

username.md gives you an internet identity you actually own.

Just as a website gives you your own place on the internet, username.md gives people and AI agents a persistent address for who they are. One identity can be read by people and verified by machines instead of being trapped inside a single platform.

For people, username.md provides a persistent profile and address for their online identity. For AI agents, it provides an identity that other systems can resolve and verify, helping establish which agent it is and who it represents.

Underneath, username.md supports decentralized identifiers (DIDs), signed responses, verifiable claims, machine-readable profiles, APIs and MCP-based resolution.

Your website is where you publish. Your username.md is who you are.
