Semrush AI Search Visibility Checker

Semrush's AI Search Visibility Checker is a free web tool that tells you whether ChatGPT, Gemini, Google AI Overviews and Google AI Mode mention or cite your brand, drawing on Semrush's database of 26M+ prompts and responses. Marketers use it as a quick GEO health check before deciding whether to pay for ongoing tracking. There is no plan as such: you get 3 free checks a day, no account required.

What the free plan gives you

Type in a domain and you get an AI Visibility Score from 0 to 100, total mentions and citations, a breakdown by platform, an estimated audience reach, your top cited pages, topic analysis and a comparison against competitors. The tool covers 220+ countries and regions. Semrush states you can use it three times a day without registering, and creating a free Semrush account unlocks some additional insights on the report.

Where the free plan stops

Each run is a one-off snapshot. There is no history, no custom prompt list and no alerting, so you cannot see whether visibility is trending up or down. Continuous monitoring lives in the paid AI Visibility Toolkit at $99 a month billed annually, which tracks 25 custom prompts with daily AI rankings for 1 domain, adds Perplexity coverage, prompt research and an AI-readiness site audit. Extra users start at $45 a month. Semrush offers a seven-day free trial of the toolkit with a card on file.

Who it suits

Any site owner curious about their AI search footprint should run the checker; three daily reports is enough to benchmark yourself against a couple of competitors. Agencies and in-house SEO teams that need weekly reporting or prompt-level tracking will need the toolkit or a rival such as Peec AI or Otterly.
