Reviewed 23 October 2026 against Semrush, Peec AI, Otterly.AI, Ahrefs and Profound pricing and product pages.
Our pick
Semrush wins because its cheapest AI plan already covers ChatGPT, Google AI, Gemini and Perplexity, and the same data carries into a full SEO suite when you need one. The Semrush AI Visibility pricing page lists the Base plan at USD 99 a month per domain, billed annually, with 25 custom prompts tracked daily, AI competitor analysis, prompt research and an AI readiness site audit. The SEO and AI Search pricing page lists Starter at USD 199 a month (USD 165.17 billed annually) with 50 prompts tracked daily, rising to 100 on Pro+ at USD 299. The trade-off is the per-domain price: an agency tracking ten clients pays for ten domains.
What AI visibility tools measure
An AI visibility tool sends a fixed set of prompts, such as "best CRM for a small law firm", to AI answer engines on a schedule. It stores each answer and reports four things:
- Mentions: how often your brand name appears in the answer text.
- Citations: how often the answer links to your pages as a source.
- Share of voice: your mentions against named competitors across the same prompts.
- Sources: which third-party pages the engines cite, so you know where to earn coverage.
The engines covered differ by plan. Most tools track ChatGPT and Google AI Overviews by default; Perplexity, Claude and Google AI Mode are often add-ons. If your question is "how do I check my Perplexity rankings", confirm Perplexity is in the plan you buy, not only in the product.
AI answers have changed how people click. Pew Research Center analyzed March 2025 browsing by 900 US adults and found users who saw a Google AI summary clicked a traditional result in 8% of visits, against 15% without one.
Why AI visibility tools report percentages, not rankings
Position in an AI answer is close to random. SparkToro and Gumshoe.ai had 600 volunteers run 12 identical prompts nearly 3,000 times through ChatGPT, Claude and Google's AI. The odds of getting the same list of brands twice were under 1 in 100, and the same list in the same order closer to 1 in 1,000 (January 2026).
SparkToro's January 2026 study found AI tools repeated the same brand list less than once in 100 runs of an identical prompt.
The same study found that how often a brand appeared across many runs was far more stable than where it appeared. That has three consequences for anyone buying an AI rank tracker:
- Prefer visibility share to position. Every tool above reports a mention or visibility rate; treat any single "rank 3 in ChatGPT" reading as one sample.
- Track enough prompts. Fifteen prompts on Otterly Lite give a direction; a few hundred on Peec Advanced or Otterly Premium give a trend.
- Watch the cadence. Daily tracking smooths noise better than a monthly snapshot.
No AI visibility score should be the only evidence that a content change worked.
How AI visibility tools differ from SEO suites
Classic rank trackers check one search result page per keyword. AI visibility tools pay for a fresh answer from each engine for every prompt, every run, which is why prompts are the unit you buy. Peec explains its limits as prompts multiplied by models multiplied by days: 25 prompts on 3 models for 30 days is 2,250 AI answers.
If you also need keyword research, backlinks and audits, a suite is cheaper than two subscriptions. Our best AI SEO tools guide ranks the suites, including Semrush and Ahrefs, on their SEO features. A dedicated tracker such as Peec AI or Otterly.AI is the better buy when an SEO team already has its suite and only needs AI answer data.
Google's guide to AI features and your website says there are no extra requirements to appear in AI Overviews or AI Mode beyond being indexed and eligible for a snippet. So the work that raises AI visibility is still ordinary: pages that answer the question, earn citations from sources the engines already trust, and stay crawlable.
How we picked
- We compared five AI visibility tools on their published plans, prices, prompt limits, engines covered per plan, tracking frequency, seats and trial terms, using each vendor's pricing and product pages as listed on 23 October 2026, in US dollars. The order weighs engine coverage at the entry price and how easily a small marketing team can start against published versus quoted pricing. Answers vary between runs, as the SparkToro study shows, so picks rest on documented coverage and limits. Our full method is on the HumanRank ranking methodology page.
How to choose
How to choose
- Write 15 to 25 prompts a buyer would ask before choosing a product like yours, mixing branded and unbranded questions.
- List the engines your buyers use. If Perplexity matters, check that the plan includes it without an add-on.
- Start two free options side by side: Semrush's free plan and Profound's 7-day trial, or Otterly's trial.
- Compare the cited sources each tool finds. The source list is the most useful output, because it tells you where to earn coverage.
- Price a full year at the prompt count you will really need, including extra engines and seats.
