Introducing Onto,
AI agents are reading your website, and most of what they get is noise.

Stripe's pricing page is 699 KB of HTML. As Markdown: 17 KB.

We're relaunching Onto: your site answers agents in clean Markdown, at the same URL, and shows you who's reading.

Free to start: Serve on one site, Read with 1,000 credits a month, no card.

Scan your site and see what agents actually get: https://t.co/mdT6o2eRDo

Building agents instead? The same engine reads any page. The Read API returns Markdown plus an AIO readability score, and it plugs into ChatGPT, Claude or Cursor over MCP.

Search is shifting from Google to AI agents.

But React sites ship heavy JS, AI bots can’t read → hallucinations or lost visibility.

Onto fixes this.
