Your name is doing a lot of jobs. Badly.
Your name is scattered
A dozen profiles, a different link list in every bio, an email per platform. When something changes, you update it everywhere — or, more likely, you don't.
Nothing proves it's you
Anyone can make a page that says it's you. username.md is the one that can prove it — every answer your handle gives is cryptographically signed.
The web's new visitors are agents
More and more of what visits the web isn't a person — it's software acting for a person. Those agents need one address where they can look you up and trust the answer.
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). 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.
A real company
A project of The Holding Company. Payments handled by Stripe — we never see your card.
