What is AnswerGap
See if AI search (ChatGPT, Perplexity, Gemini, AI Overviews) cites you — and who it cites instead. Plus an AI-readiness audit. AnswerGap reads the AI answer already on your screen and tells you whether it cites your site, who it cited instead, and exactly how to close the gap — no crawler, no setup, no dashboard to log into.
Ranking #1 on Google no longer means you appear in AI answers. AI Overviews, ChatGPT, Perplexity and Gemini each pick their own sources. AnswerGap reads the live answer in front of you and shows who got referenced, whether you're one of them, and which competitors won the spot you didn't — the visibility gap you need to close.
WHAT YOU GET
Free
- Who AI references — the real sources behind the answer you're looking at, across Google AI Overviews, ChatGPT, Perplexity and Gemini.
- AI-readiness score — on any page, a 0–100 score for how citable it is to AI, with the top issues ranked by impact.
- 5 checks per day — no account, no setup.
Pro (one-time $129)

- Your visibility gap — see exactly which competitors get cited for a query when you don't, plus the page that won the mention, so you know what to beat.
- Coverage matrix — a grid built from every check you've run, query by query across the four engines: cited, checked-but-not-cited, or never checked.
- Full AI-readiness audit — the complete report with step-by-step fixes plus copy-paste JSON-LD schema, not just a score.
- Share-of-Voice with your own AI key — run your own list of prompts through your OpenAI or Perplexity key and measure how often AI references you vs competitors. Your key and prompts go directly to that provider (OpenAI or Perplexity) and nowhere else — never to AnswerGap servers.
- Scheduled Share-of-Voice monitoring — automatically re-run your Share-of-Voice prompts (using your own AI key) on a daily or weekly timer. New results fill in the coverage matrix, and a toolbar badge plus an opt-in desktop alert flag you when your citation rate moves.
- White-label client report — one-click, brandable PDF for agencies and stakeholders.
WHY ANSWERGAP
- Works on the live answer — it reads what's actually on screen. No crawler, no synthetic queries, no platform to log into.
- Private by design — pages are analyzed locally on your device. The optional Share-of-Voice feature sends your prompts only to the AI provider whose key you supply (OpenAI or Perplexity); nothing is ever sent to AnswerGap.
HOW IT WORKS 1. Open an AI answer for a query you care about. 2. Click the AnswerGap icon. 3. See who's cited, whether it's you, and how to close the gap.
