Your AI Share of Voice: How Often AI Recommends You vs Competitors
When buyers ask an AI assistant for the best option, only a handful of brands get named again and again. This free tool puts the same buyer question to Perplexity five times and charts your slice of the recommendations against the competitors taking it. One engine, five prompts, one moment in time — every result shows the exact prompt, the engine, the timestamp and the sources it cited.
This is what a result looks like. Run yours above for the real thing.
AI Market Share · “family dentist” · Austin, TX
Read it like this: across five identical buyer prompts, Sunrise was named in one answer and its four rivals accounted for the other nine mentions — so Sunrise holds 10% of the recommendations, and the practical question is what the 50% brand has that it doesn't. Your own result comes with the exact prompt we sent, the engine, the timestamp, the sources it cited and the denominator behind every percentage.
Frequently asked questions
What is AI share of voice?
AI share of voice is the percentage of AI assistant answers that recommend your brand versus your competitors for a given search. When someone asks an AI assistant for the best option in your category, a few names come up repeatedly — your share of voice is how big a slice of those recommendations you win. This tool measures it by putting one buyer question to Perplexity five times and tallying who gets named across those five answers.
Which AI engine does this tool actually query?
Perplexity, using live web search with citations. One engine, five runs of the same buyer question. If Perplexity is unavailable for a run, the tool falls back to an AI model's training knowledge and labels the result an estimate rather than a live check. It does not query ChatGPT, Gemini or Claude, and a result here says nothing about what those engines would answer.
How is the share-of-voice percentage calculated?
A brand scores one mention per answer it appears in, counted at most once per run. Its share is that brand's mentions divided by the total mentions across every brand in the table, times 100. Example: across five prompts you are named once, rival A five times, rival B three times and rival C once — total 10 mentions, so your share is 10%. Every result shows the exact prompt sent, the engine, the timestamp, the sources cited and the denominator, so you can check the arithmetic yourself.
How do I check if ChatGPT and Perplexity recommend my brand?
This tool answers the Perplexity half directly: enter what your customers search for plus your website, and it asks Perplexity five buyer questions, then charts how many answers name you versus each competitor. It does not query ChatGPT, so treat the result as one engine's view rather than a verdict on AI search overall. Repeating the same buyer question in ChatGPT yourself is the honest way to compare the two, and any tool claiming to measure both in one click is worth asking how.
Can I monitor my AI search visibility over time?
This free tool is a one-shot snapshot, not an ongoing monitor — it shows where you stand right now. To track your AI share of voice week over week and get alerted when your ChatGPT and Perplexity mentions change, that's the paid RankAgent product, which re-checks your visibility on a schedule. Start with the free snapshot here, then upgrade for continuous AI search monitoring.
Is this AI mention tracker free?
Yes — the share-of-voice snapshot and your AI market-share bar chart are free with no login. Enter your email to unlock the full per-competitor breakdown table. Ongoing AI mention tracking and weekly brand monitoring are part of the paid RankAgent plans, not the free one-shot check.
