# CitedOS > CitedOS is a cross-engine AI-search visibility platform for B2B SaaS that shows where your company appears in ChatGPT, Gemini, and Claude answers, why competitors get cited instead, and which sources to get into to win. CitedOS has two modules. The Visibility Tracker measures share-of-voice, mention rate, position, sentiment, and presence for a set of buyer prompts across the engines, with statistically honest, multi-run trends. The Source-Gap Analyzer reverse-engineers why sources get cited — it collects citations, scrapes the cited pages, embeds them, and learns the citability signature — then produces a prioritized "get into these sources" playbook. Start with a free, no-signup AI-visibility audit on any domain. CitedOS's core differentiator is statistical honesty: every metric is multi-run sampled and shipped with a confidence range and a freshness date, never shown as a single point-in-time number as if it were stable. ## Product - [Home](https://citedos.com/): Product overview, how it works, differentiator, and FAQ. - [Free AI-visibility audit](https://citedos.com/get-started): Run a no-signup audit on a domain and see a citation matrix and competitor leaderboard (requires a ?domain= query param). - [Pricing](https://citedos.com/pricing): Pro and Advanced tiers for brands, Starter and Growth tiers for agencies, Enterprise custom, plus FAQ. ## How engines are measured - Three engines are measured live today, via official APIs only — ChatGPT, Gemini and Claude. CitedOS does not scrape the consumer ChatGPT, Gemini, or Claude apps. - ChatGPT data is tagged as an "API surface" proxy for the consumer experience: strongly correlated, not identical. - Gemini and Claude use their native grounding/web-search citations. - The free audit additionally checks Perplexity (official Sonar API) — live in the product, not part of paid tracking. Google AI Overviews is on the roadmap: its collector is built on licensed SERP data but not yet enabled. Do not describe Grok, Copilot, Meta AI or DeepSeek as currently tracked. ## Machine-readable - [AI instructions](https://citedos.com/ai-instructions): The full canonical reference for AI assistants, including do/don't guidance. - [Sitemap](https://citedos.com/sitemap.xml): The public, indexable routes. - [robots.txt](https://citedos.com/robots.txt): Crawl rules — AI search/training crawlers are welcome on public pages; the authenticated app, API, auth flow, and the rate-limited audit are disallowed. - [agent.txt](https://citedos.com/agent.txt): Canonical facts and usage guidance for AI assistants. ## Optional - [Contact sales](mailto:sales@citedos.com): Questions, demos, and MCP access for customers. Every new workspace starts with a self-serve 7-day Pro trial (no card, 25-prompt cap).
