who are /u/?
One Handle. Now Make it Yours.
Claim username.md/you — a single page and address for everything you are online. People can read it. Apps and AI agents can verify it.
You own it.
Founding access: $9 buys your handle outright. The profile API, signed responses, and Bluesky binding are live now; full refund if we don't ship the rest by 2026-09-30.
Your information is scattered on the internet.
You have email. You have handles for games and different handles for social media. Username unifies them into your internet address.
What is an internet address?
It's called a did:web — one verifiable address for everything you are online — and it's available exclusively through username.md.
Get your name before someone else does
Handles are first come, first served. Claim yours once and it's yours — your email, your profiles, and your proof all answer at one name.
Your agents will have one too
Your username is how your agents will talk to other agents and other people. Each will have a username. Get a name for your agent →
This is a handle. One command, one verified answer.
Browsers get a page. Programs get JSON, Markdown, or a signed bundle — same name, same truth. Look up a live handle →
Claim it once. Use it everywhere.
Claim
Pick a handle (5+ characters, $9 one-time; or see premium handles for fewer characters). Your page goes live at username.md/you, and [email protected] starts forwarding to the inbox you already use.
Verify
Prove a domain with a DNS record, bind your Bluesky account so @you.username.md resolves across the network, or import your old Keybase proofs. Each check becomes a signed claim anyone can verify.
Connect
Put the one link in every bio, signature, and README. Change a link once and everyone who looks you up gets the new answer.
Use
People visit the page. Apps fetch JSON. AI agents read Markdown, check the signature, and follow your rules for how you want to be contacted.
Don't take our word for it. Check the math.
Signed responses
Every answer is Ed25519-signed per RFC 9421, against public keys anyone can fetch. Verify it yourself →
Open standards
did:web, W3C Verifiable Credentials, RFC 9421 — open formats over plain HTTPS. No walled garden, including ours.
Open API
Reads are free, no signup, fully documented — one URL that answers as HTML, JSON, or Markdown depending on what asks.
Refund promise, in writing
Full refund if we don't ship by 2026-09-30. We mean it.
