Documents you can trust.

tdoc turns PDFs, DOCX, and HTML into typed, queryable, cryptographically‑signed documents. Every number carries a declared type. Every archive hashes to the same bytes, always. Ship it in one REST call.

Round-trip — · Edge — Hit /docs for the full OpenAPI surface.

A format, not a file.

AXON separates what a document says from how it renders. The content tree is typed. A pvalue is a p-value. A measure carries units. A currency knows its ticker.

Your agent never has to guess whether “p = 0.03” is a probability, a typo, or a page number. It’s declared. It’s signed. It round-trips to the same bytes.

The ledger.

Six invariants the reference impl keeps
01
Typed every node.
Cells declare data-type: pvalue, measure, currency, ci, date, &c. Your downstream code never guesses.
Schema
02
AQL — query in one line.
“Every p‑value < 0.05 in this 300‑page paper.” No LLM needed. Runs in milliseconds against the parsed tree.
Query
03
Ed25519 signed.
Signatures cover the canonical byte stream + manifest. Tamper once — verification fails forever.
Integrity
04
Byte‑deterministic.
Encode the same document twice, produce the same bytes. Hash it, sign it, audit it, diff it — no wall-clock drift.
Reproducible
05
Accessible by design.
Alt-text coverage, equation descriptions, reading-order validation — enforced in validate(), not bolted on.
A11y
06
Open format, always.
Apache 2.0 reference impl. The spec lives next to the code. Run it offline, self-host, fork it — we still win.

2026 — present

Every AI team is losing 20–40 % of document quality to broken PDF ingestion. Tables become strings. Equations become gibberish. P‑values lose their type. tdoc gives agents the same structured view a database has — so your models cite a number, rather than merely see it.
