AsciiDoc for humans & AI
The document format
The document format
that gets along
with AI agents
AsciiDoc (.adoc) is an explicit, structured format that stays stable even when AI writes it. Learn it here — with a live playground.
Structure at a glance
Unlike space-sensitive Markdown, AsciiDoc makes headings, admonitions and tables explicit syntax. AI output stays stable through conversion — friendly to both humans and machines.
= A doc easy for AI to write Because structure is explicit, AI reliably produces valid AsciiDoc. [NOTE] AI agents output into .adoc structure smoothly. == Explicit headings [source,bash] $ asciidoctor my-doc.adoc DONE
Why AsciiDoc wins with AI
🗼
Explicit structure
Headings, tables and notes are part of the syntax — no space-wrapping ambiguity.
⚙️
Deterministic conversion
asciidoctor converts to HTML deterministically, so AI output → build → verify can be automated.
📦
One source, many outputs
A single .adoc renders to HTML, PDF and slides (Reveal.js) consistently.
AsciiDoc vs Markdown
| Aspect | AsciiDoc | Typical Markdown pitfalls |
|---|---|---|
| Structure | Explicit syntax | Space/indent ambiguity |
| Determinism | Reproducible output | Results vary across dialects |
| Outputs | HTML / PDF / slides | Depends on extensions |
