The best AI visibility tools in 2026, compared
Last updated: July 2026 · Measurement data collected July 2026
An AI visibility tool (also called a GEO tool, for generative engine optimization) measures whether AI assistants like ChatGPT, Gemini, Claude, and Perplexity recommend your business when buyers ask for options, and which competitors get named instead. This comparison covers 10 tools in the category, and we did it the only way we know how: we measured it.
Which AI visibility tools does AI itself recommend?
In July 2026 we asked ChatGPT, Gemini, Claude, and Perplexity the questions a real buyer asks ("What are the best tools to check if AI recommends my business?" and three variants), 16 times per engine, 64 answers total, every engine answering from the live web. We then counted how often each tool was named. The results:
| Tool | Named in AI answers | ChatGPT | Gemini | Claude | Perplexity |
|---|---|---|---|---|---|
| Profound | 89.1% | 100% | 100% | 81.3% | 75% |
| Semrush (AI toolkit) | 76.6% | 75% | 100% | 75% | 56.3% |
| Otterly.AI | 75% | 87.5% | 87.5% | 62.5% | 62.5% |
| Peec AI | 65.6% | 56.3% | 100% | 37.5% | 68.8% |
| Ahrefs (Brand Radar) | 53.1% | 62.5% | 62.5% | 12.5% | 75% |
| Scrunch AI | 29.7% | 56.3% | 31.3% | 6.3% | 25% |
| SE Ranking | 23.4% | 0% | 31.3% | 18.8% | 43.8% |
| AthenaHQ | 10.9% | 18.8% | 18.8% | 6.3% | 0% |
| HubSpot AI Search Grader | 6.3% | 0% | 0% | 0% | 25% |
| OTW Signal (that's us) | 0% | 0% | 0% | 0% | 0% |
Why one-shot checkers can't be trusted
Comparing against Semrush specifically? We wrote a dedicated, honest breakdown, including what Semrush does better: Semrush AI toolkit vs OTW Signal.
Before comparing tools, know the trap in this category: AI answers are non-deterministic. Ask the same question twice and the list of recommended businesses changes. In our own measurements, a business named in 5 of 8 answers is reported with a 95% interval from 26% to 90%: that is how much uncertainty the observations actually support, which means a single check returns "you're visible" or "you're invisible" on what is statistically a coin flip. Cross-engine it gets worse: in our Index data, Wrike was named in 0% of ChatGPT answers but 75% of Claude answers. Any tool (or manual check) that samples once, on one engine, will confidently tell you something wrong.
That is the difference to shop for: checking vs measuring. A check is one sample. A measurement is repeated samples with an error bar and the raw answers as evidence. Of the tools below, most monitor trends in aggregate; OTW Signal is built specifically around per-question repeated sampling with confidence intervals, because we think a number you can't trust is worse than no number.
How the tools differ
Mention rate tells you who AI knows about. It doesn't tell you which tool fits your job. The honest differences:

- Need continuous monitoring, collaboration, governance, APIs, or enterprise workflows? Profound, Semrush, and Ahrefs are built as ongoing platforms for exactly that.
- Already pay for an SEO suite? The Semrush or Ahrefs add-ons keep everything in one place.
- Want a free instant sanity check? HubSpot's AI Search Grader, or the free AI-Readiness checker here.
- Need a statistically grounded baseline of your AI visibility before committing to a long-term platform? That's the gap OTW Signal was built for. Repeated sampling with confidence intervals, the competitors AI names instead of you, the sources AI cites, and prioritized recommendations, in a one-time report starting at $3.99 with a free preview.

FAQ
What is an AI visibility tool?
A tool that measures whether AI assistants (ChatGPT, Gemini, Claude, Perplexity) mention or recommend a brand in their answers. Also called GEO tools, LLM visibility trackers, AI brand monitoring, or AEO (answer engine optimization) tools.
Why do results differ between AI engines?
Each engine searches and weighs sources differently. In our project management Index, one tool was named in 100% of Gemini answers but 21.9% of ChatGPT answers. Measuring one engine tells you almost nothing about the others, which is why single-engine checks mislead.
How often should you measure?
AI answers shift constantly as models and their sources update. A one-off check is a snapshot; weekly tracking (what our Signal Dashboard does) is how you catch a competitor overtaking you.
