How possiblymadebyahuman records writing, how to check a record from your own browser, and what a conformant producer has to do.

Start here

• What this is
  A signed record of how a piece of writing was written.

Write a record

• Write in the browser
  Use the first-party drafting page when you want a no-install PMBAH record for text written inside that page.
• Write in Emacs
  Native pmbah-mode for content-blind writing records from GNU Emacs.
• Bind and check a document
  Bind the text you signed to a record, and let a reader check a document against it in their browser.

Read and verify a record

• Records and short signatures
  How a buffer mutation log becomes a hash-addressed record with a short, shareable URL.
• How to verify a record
  Recompute the record's BLAKE3 hash in your own browser and compare it to the stored hash.
• Server-observed commitments
  What the server-observed checkpoints on a record mean, and the limits of what they say.

How it holds up

• Threat model
  Who and what this product can and cannot defend against.
• Content-blind privacy model
  What public records store, what they do not, and what the signer controls before upload.

For implementers

• Producer conformance
  What it takes for a producer (browser extension, Emacs minor mode, or anything else) to be considered conformant.
• Deployment and routing
  How `/`, `/docs/*`, `/write`, `/api/*`, and `/<short_signature>` are served from a single container.

Policies

• Terms / Service Notes
  What you can expect from this service, and what the service expects from you.
