# Coderax > Coderax is an AI visibility audit for B2B SaaS websites. It scans a public website and reports how ready it is for AI answer engines like ChatGPT, Perplexity, Gemini, Google AI Overviews, Claude, and Copilot — then delivers a scored report with prioritized, actionable fixes. Coderax audits and scores the cross-engine signals answer engines read before they cite a page — crawlability, Schema.org structured data, entity clarity, FAQ/comparison coverage, and llms.txt readiness. It covers the major answer engines (ChatGPT, Perplexity, Gemini, Google AI Overviews, Claude, Copilot); it does not guarantee placement in any single engine, but makes a site legible enough to become the cited source. Coderax helps B2B SaaS founders, marketers, and agencies improve crawlability, structured data, content signals, and llms.txt readiness. A free scan (about 30 seconds) returns an AI Visibility Score with a category breakdown; the full $29 audit adds the complete prioritized report and a publishable llms.txt draft. ## What Coderax offers - [Free AI Visibility Scan](https://coderax.ai): Score in ~30 seconds, category breakdown, and comparison against a curated benchmark panel of B2B SaaS sites. - [Full Audit — $29](https://coderax.ai/pricing): Polished PDF report, complete Markdown audit, prioritized implementation checklist, and a publishable llms.txt draft.
