ESLint for AI search — audit AI crawler access, llms.txt, structured data and citability for ChatGPT, Perplexity, Claude & co.
ESLint for AI search. Lint your website for AI-search readiness — AI crawler access, llms.txt, structured data and citability.
geolint fetches the page, its robots.txt and llms.txt, evaluates 51 known AI crawler tokens against your robots.txt, runs 52 audit rules, and prints a scored report with a concrete fix for every finding.
- AI answers are the new front page. ChatGPT, Perplexity, Claude, Copilot and Google AI Overviews send traffic — or don't — based on whether their crawlers can fetch and quote your pages. - Most sites accidentally block or confuse AI crawlers. A stale Disallow: /, a noindex left over from staging, a client-rendered page that looks empty to a bot that doesn't run JavaScript. - Existing tools are blocklists or score-only web apps. They tell you to block everything, or give you a number with no path to improve it. geolint is the linter: concrete findings, concrete fixes, runnable in CI on every PR.
52 rules across 5 categories — geolint rules lists them all, and docs/rules.md documents what each rule checks, why it matters and how to fix violations.
