Why Markdown

Rich text is expensive to read

A model doesn't read your document — it reads tokens, roughly four characters each. Every tag, style attribute, table cell wrapper, and layout artifact inside a PDF or Word file becomes tokens too, and you pay for all of them before a single sentence of meaning arrives.

Markdown carries the same structure in plain characters. A heading is two symbols instead of a nested element; a table is pipes instead of thirty tags. The document shrinks, so the same context window holds more of it, and each request costs less.

Accuracy improves for the same reason. When headings, lists, and tables survive as unambiguous text, an agent stops guessing where a section starts and what a column means.

HTML source

<table class="tbl data-table">
  <thead>
    <tr><th scope="col">Region</th><th scope="col">ARR</th><th scope="col">YoY</th></tr>
  </thead>
  <tbody>
    <tr><td>North America</td><td>$12.4M</td><td>+18%</td></tr>

What that saves

48% off every token you send

Take the table above as one section of a 40-page report — about 25,600 input tokens as HTML, 13,200 as Markdown. Run a thousand of those reports through an agent and the difference shows up on the invoice.
