CitedOS measures ChatGPT, Gemini, Claude, Grok, DeepSeek, Google AI Overviews and Perplexity through their official APIs, plus Google AI Overviews through licensed SERP data. When an engine or a collector degrades, the dashboard shows last-known data with a staleness flag — never a blank screen.
We measure ChatGPT, Gemini, Claude, Grok, DeepSeek, Google AI Overviews and Perplexity through their official APIs, plus Google AI Overviews through licensed SERP data. If one is unavailable, its data goes stale-flagged, not silently missing.
A broken collector shows last-known data with a freshness stamp — by design, not by accident.
Search indexes refresh on their own clock, so each figure wears the time it was measured.
