A growing share of customers never see your website: they ask ChatGPT, Perplexity, Gemini or Google’s AI Mode and act on the answer. AI visibility tools measure what those assistants say when people ask about your category: whether they mention your brand, in what position, which sources they cite and which competitors they recommend instead. We compared the main options, from free checks to enterprise platforms. Prices were checked on each vendor’s website on October 21, 2026.
How AI visibility tools work
Every tool in this list does the same basic thing: it sends a set of prompts, the questions your customers would ask, to one or more AI assistants every day, and records the answers. From those answers it calculates how often you are mentioned (your share of voice), your average position, the sentiment of the mentions and the pages the assistants cite. Prices depend mainly on two things: how many prompts you track and how many AI engines you track them in.

The tools in detail
SE Ranking
Best for: SEO teams that want AI tracking without a second tool. Price: the Core SEO plan is $129/month with 100 daily AI prompts; the AI Search add-on, which covers AI Overviews, AI Mode, ChatGPT and Perplexity in depth, is $89/month.
If you already need an SEO platform, SE Ranking is the cheapest way to add AI visibility to it. You can compare your Google rankings and your AI mentions for the same topics in one place, which helps explain why traffic changes when AI answers change.
- Pros: AI tracking sits next to rank tracking, audits and backlinks, with a 14-day trial that needs no card
- Cons: the most complete AI reports require the paid add-on
Nightwatch
Best for: agencies and local businesses tracking rankings and AI answers together. Price: Starter is €79/month billed yearly (€99 monthly) with 500 keywords and 50 AI prompts; Professional is €159 with 150 prompts.
Nightwatch is a rank tracker first, but every plan includes AI prompt tracking. That makes it a practical choice for teams that report classic rankings and AI visibility to the same clients.
- Pros: AI prompts on every plan, daily and on-demand checks in any location
- Cons: fewer prompts than dedicated AI trackers at the same price
Semrush AI Visibility Toolkit
Best for: teams already using Semrush. Price: $99/month with 25 tracked prompts; extra prompts cost $60/month per 50; Semrush One bundles start at $199/month with 50 prompts.
Semrush’s toolkit shows your brand’s share of voice, sentiment and cited sources across the main AI assistants, and its prompt research helps you decide which questions to track. It is the natural choice if Semrush is already your main SEO tool.
- Pros: integrates with Semrush’s keyword and competitor data, plus prompt research to find what people ask
- Cons: a small prompt allowance for the price unless you buy a bundle

Ahrefs Brand Radar
Best for: brands that want market-wide benchmarks. Price: custom prompts start at $50/month and some are included in paid Ahrefs plans; the AI Visibility Index starts at $199/month.
Brand Radar combines your own prompts with a large pre-collected database of questions, so you can compare your AI visibility with competitors even for prompts you did not think of. Ahrefs customers get YouTube, TikTok and Reddit data while it is in beta.
- Pros: the widest engine coverage in this list, including Copilot and Claude, and an index built from a large prompt database
- Cons: small custom-prompt allowances on the entry tiers, and Claude checks cost more
Otterly.AI
Best for: small businesses and freelancers starting with AI tracking. Price: Lite is $29/month for 15 prompts; Standard is $189/month for 100 prompts.
Otterly.AI is a focused AI visibility tracker with a low entry price. Fifteen prompts are enough to monitor a small set of key questions for one brand, and the Standard plan adds API access.
- Pros: the cheapest dedicated tracker, daily checks, and ChatGPT, AI Overviews, Perplexity and Copilot on every plan
- Cons: Gemini, AI Mode and Claude cost extra
Peec AI
Best for: marketing teams that want clean competitive reports. Price: from about €89/month; plans include three AI models, with a fourth as an add-on.
Peec AI tracks your visibility, position and sentiment against competitors every day and shows which sources the assistants rely on, which tells you where to earn mentions.
- Pros: clear competitor benchmarks and source analysis, aimed at marketing teams
- Cons: prompt limits vary by plan and the pricing page does not list them publicly
Profound
Best for: enterprises and large brands. Price: custom enterprise pricing, with a free trial of 50 prompts for 7 days.
Profound is built for companies that need broad coverage, many prompts and support. The free trial runs a recommended prompt set across ChatGPT, Gemini and AI Overviews, which is a useful first benchmark.
- Pros: up to nine answer engines, including Claude, DeepSeek and Copilot, and editable prompt sets
- Cons: no public self-serve pricing for most teams
How to choose an AI visibility tool
- Start with a free check. Run our AI Visibility Checker to see whether AI models know your brand at all. If they do not, fix that first: tracking will only confirm it.
- Pick prompts before tools. Write down the 10 to 30 questions your customers really ask. That number tells you which plan you need.
- Track the engines your customers use. ChatGPT and Google AI Overviews matter for almost everyone; Perplexity, Gemini, Copilot and Claude depend on your audience.
- Combine it with SEO data. AI answers cite web pages. A tool that also tracks rankings, like SE Ranking or Nightwatch, helps connect what you rank for with what AI cites.
- Expect noise. AI answers change between runs and users. Look at trends over weeks, not single answers.
