VistoFormat
robots.txt, rebuilt for AI readers
obots.txt told crawlers how to read the web. AI reads differently — it extracts and cites. Visto Format is an open spec for structuring content so LLMs can read it, plus a BYOK tool to measure if you're actually getting cited. Spec is free and open source.
Hi Product Hunt 👋
For ~20 years, robots.txt told crawlers how to read the web. But AI doesn't crawl-and-rank — it extracts meaning and cites. There's no standard for that, and no way to measure if your content actually gets cited.
Visto Format is my attempt at both:
🔓 **Visto Format (open source)** — a spec for structuring page content as "Structured Content Units": compact, self-contained facts shaped for how LLMs read. It's JSON-LD, aimed at AI extraction instead of search rich-results. MIT on GitHub.
📊 **Visto Insights** — measure your actual AI citation rate. Bring your own Gemini key (BYOK); it runs your target queries and tracks whether you get cited, over time.
🛡️ **Visto Shield** — honeypot tokens that log which crawlers actually read your content.
The honest part: I built the measurement layer because I didn't trust my own gut — and I was right not to. On my own site, citation went 0% → 17% → 0% → 25% → 35%. AI citation is probabilistic, not a fixed score. And SEO is still the foundation: structuring for AI did little on a site Google didn't already know. It's n=1 and Gemini-only so far — I'm sharing the method as much as the results.
BYOK means you pay the model provider directly; I charge a flat fee. Free tier, Starter $29/mo, Pro $79/mo.
