Track your brand inside AI answers

AI visibility monitoring tracks how your brand appears in AI-generated answers across engines like ChatGPT, Perplexity, Gemini and Claude, and in Google AI Overviews. Over 70% of discovery queries now return a zero-click AI answer: category research, comparisons, recommendations. Where your brand appears in those answers, or fails to, directly affects traffic. TrustData probes ChatGPT and Perplexity daily on every plan, reads AI Overviews per keyword, and keeps every answer in full.

If monitoring is all you need, that is often the right answer: Otterly's Lite plan starts at USD 29 a month for 15 prompts, pricing checked August 2026. TrustData starts at 199 EUR because AI visibility arrives with the rest: the first-party tracking that sees the crawlers pass, the traffic ChatGPT sends read as a channel beside the others, and the attribution of your Meta and Google spend on one deduplicated conversion. You are buying the join, not the probe. On engines included in the base plan, Otterly is ahead, four against three, so compare depth per prompt rather than logos.

Because an average hides the one thing you can act on. A brand can be crawled thoroughly and still be invisible in answers, or be mentioned constantly and never referred. Blending six signals into one number tells you that something is wrong without telling you what. TrustData scores each signal separately against a cut-off of 60, then names exactly one thing to fix first: the lowest signal below the cut-off whose prerequisites are already clear. A signal with too little data reads as insufficient data rather than as a zero.

AI Overviews are read per tracked keyword and reported as a presence rate over four weeks with the number of readings behind it, because an Overview does not show on every search or for everyone. When it appears, we record whether you are cited, in which position, and the snippet taken from your page. AI Mode is a separate answer with its own sources: it is read once per tracked keyword and billed per keyword, from 29 EUR. Both sit side by side on the same row as your impressions, clicks and conversions, never blended into one Google score.

TrustData probes 6 engines: ChatGPT, Perplexity, Gemini, Claude, Mistral and DeepSeek, and reads two Google surfaces, AI Overviews and AI Mode. ChatGPT and Perplexity are included in every plan, with AI Overview tracking. Gemini (25 to 199 EUR), Claude (99 to 799 EUR), Mistral and DeepSeek (15 to 99 EUR each) are per-engine, per-tier monthly add-ons. Google AI Mode is read once per tracked keyword rather than probed, so it is priced per keyword at 29 to 299 EUR. There is no per-probe overage: engine cost is included in the add-on price and volume caps at your tier's probe budget. Grok was dropped in July 2026 because it never returned a usable row.

The Brand Health Score is a 0 to 100 composite measuring how consistently your brand appears in AI answers. It is a weighted average of your with-search mention rate (60%) and no-search mention rate (40%) across all engines and question types, updated daily. It returns no value at all below 5 probes rather than reporting a number built on noise. It is a supporting metric. The diagnosis that names the signal to fix, not this score, is how you decide what to do next.

We do not claim that, and we will not report it as if we could. Paid media, audiences and smart links are measured causally through holdout tests, with confidence intervals. AI visibility, content and SEO are measured as leading indicators: citation rate, share of voice, ranking lift, each with its noise level. AI-referred visits are read as sessions and conversion rate, like any channel, not as caused revenue. Any tool telling you it has attributed revenue to a ChatGPT citation is overstating what the data can carry.
