11 AI Visibility Tools Compared on Price per Prompt
An AI visibility tool tracks how often AI assistants such as ChatGPT, Perplexity, Gemini and Google AI Overviews mention or cite your brand for a set of prompts. Entry prices run from free tiers and $17 a month (Rankscale, yearly) to custom enterprise contracts (Profound). The fairest way to compare them is cost per tracked prompt on the engines you need, which ranges from under $1 to about $2 a prompt on the plans we could price.

Price per prompt at a glance
Figures come from each vendor's pricing page or documentation on October 21, 2026. "Per prompt" divides the monthly price by the prompts the plan includes. Credit-based tools are shown per credit instead, because one prompt can use several credits.

Our service is the last row. Its price includes the work of fixing your site, so dividing by prompts would make it look like the most expensive tracker when it is a different product.
What to look for in an AI visibility tool
AI visibility is how often and how well AI systems present your brand. A good tracker should report four numbers per prompt: whether you were mentioned, whether you were cited with a link, your position among the brands named and which sources the answer used.
Beyond that, three plan details change the real cost:
- Engines per plan. Many trackers show eight or more engines on the product page but include three or four on the entry plan.
- Run frequency. Daily runs give smoother trends than weekly ones, since AI answers vary between runs.
- Seats and projects. Agencies tracking several clients hit project limits before prompt limits.

1. Otterly.AI
What it does: Otterly.AI is a straightforward tracker: add search prompts, and it records brand mentions and cited links on ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot. Gemini, Claude and Google AI Mode are paid add-ons.
Who it's for: Solo marketers and small agencies who want visibility numbers without a long setup.
Price: Lite is listed at $29 per month for 15 prompts, Standard at $189 for 100 and Premium at $489 for 400. Annual billing is 15% off.
Honest limitation: Per-prompt cost barely drops from Lite to Standard, and the add-on engines push it up. Our Otterly.AI review breaks this down.
2. Rankscale
What it does: Rankscale measures visibility with credits, up to 4,800 tracked answers a month on Pro across nine engines, plus brand dashboards and page audits.
Who it's for: Budget-conscious teams that want many engines and are fine with credit math.
Price: Essentials $17 per month (yearly only). Pro $99 per month with 1,200 credits and a 7-day trial. Pro+ $229, Growth $385.
Honest limitation: Credits make it harder to predict how many prompts you can track across how many engines until you run it.
3. Semrush AI Visibility Toolkit
What it does: Semrush gives you an AI Visibility Score, competitor sentiment comparison, prompt and topic ideas, daily prompt tracking, an AI crawler site check and reports.
Who it's for: Semrush customers who want visibility reporting next to SEO reporting.
Price: $99 per month.
Honest limitation: The knowledge base page does not state a prompt allowance, so cost per prompt cannot be compared with the dedicated trackers.
4. Ahrefs Brand Radar
What it does: Brand Radar measures brand visibility across AI answers, YouTube and Reddit, which makes it more of a share-of-voice tool than a prompt tracker.
Who it's for: Brand and PR teams that want to see the full set of places AI answers draw from.
Price: Custom prompts from $50 per month and free on paid Ahrefs plans. The AI Visibility Index is from $199 per month with 83 prompts a day.
Honest limitation: If you are not already an Ahrefs customer, you pay for an SEO suite to get the free tier.
5. Writesonic
What it does: Writesonic tracks prompts daily on ChatGPT, Gemini and Google AI Overviews and includes ads monitoring on every plan. It also has an AI writer.
Who it's for: Teams that want a tracker bundled with a writing tool.
Price: Starter is $79 a month billed annually for 50 prompts. Basic is $199 for 100 prompts.
Honest limitation: Sentiment analysis starts on Growth at $399 a month, so the cheaper plans report presence but not tone.
6. Peec AI
What it does: Peec AI tracks visibility on ChatGPT, Perplexity and Gemini, with AI-suggested prompts that show search volumes, competitor rankings and cited sources. It says coverage is calculated by multiplying tracked prompts by active models and tracking frequency.
Who it's for: In-house marketing teams and agencies. Peec says more than 3,500 brands and agencies use it.
Price: Starter, Pro and Advanced amounts did not display on the pricing page when we checked. Enterprise is custom.
Honest limitation: Without a visible price you cannot work out cost per prompt up front.
7. SE Ranking AI Search Toolkit
What it does: It records whether your domain is mentioned or linked in AI answers on Google AI Overviews, AI Mode, ChatGPT and Gemini, your position among cited sources and how you compare with five competitors, with history over time.
Who it's for: SE Ranking users and agencies that bundle AI visibility into client reports.
Price: Not listed on the toolkit page. There is a 14-day trial and a free checker with 5 attempts a day.
Honest limitation: No Perplexity or Copilot in the listed coverage.
8. Scrunch
What it does: Scrunch tracks citations and agent traffic across ChatGPT, Claude, Gemini, Perplexity, Google AI Mode, AI Overviews and Meta. Its plans also include industry prompts, 1,000 on Starter, on top of your custom prompts.
Who it's for: Brands that track many prompts and want the lowest per-prompt rate among the published prices here.
Price: Starter $300 month-to-month or $250 billed annually with 350 custom prompts. Growth $500 or $417 billed annually with 700.
Honest limitation: The $300 entry point is high for a small business that only needs 20 or 30 prompts. See our Scrunch AI review.
9. AthenaHQ
What it does: AthenaHQ meters visibility tracking by AI response across up to 11 models, with unlimited topics and prompts on Starter.
Who it's for: Teams that want to start free and want flexibility in how they split usage across models.
Price: Free tier with 300 credits. Starter $295 per month with 3,600 credits.
Honest limitation: API access and extra credits cost more on Starter.
10. Profound
What it does: Profound tracks answers daily across up to nine engines on Enterprise.
Who it's for: Large companies that need daily data across many engines and custom terms.
Price: Free 7-day trial with 50 prompts. Enterprise is custom.
Honest limitation: It cannot be priced per prompt without a quote.
11. AI Search Optimization (our service)
What it does: Our flat plan includes visibility monitoring of up to 50 prompts a month across ChatGPT, Perplexity, Gemini and Google AI Overviews, but the main product is the work. After a free audit, month one fixes AI crawler access, schema, llms.txt, entity data and content gaps, then we keep optimizing.
Who it's for: Business owners whose problem is not missing data but missing time to act on it.
Price: $299 per month, 3-month minimum, or $2,990 a year. Custom quote over 500 pages.
Honest limitation: As a pure tracker it is poor value. Scrunch or Otterly give you more prompts for the money. Choose us only if you want the fixes done. Details are on our AI search optimization services page.

Frequently asked questions
What is an AI visibility tool?
An AI visibility tool sends a set of prompts to AI assistants like ChatGPT, Perplexity, Gemini and Google AI Overviews and records whether your brand is mentioned or cited. It tracks the results over time and compares you with competitors.
How much does an AI visibility tool cost?
On vendor pages we checked in October 2026, paid plans started at $17 a month (Rankscale Essentials, yearly) and ran to $300 a month or more for higher-volume tools like Scrunch. Several vendors, including Profound, only quote enterprise prices on a call.
What is the cheapest AI visibility tool per prompt?
Among the plans with published prices and prompt counts, Scrunch Starter worked out to about $0.86 per prompt and Writesonic Starter about $1.58. Otterly.AI was around $1.90. Credit-based tools like Rankscale and AthenaHQ depend on how many engines you track.
Is there a free AI visibility tool?
AthenaHQ has a free tier with 300 credits, Profound offers a 7-day free trial and SE Ranking has a free checker with 5 attempts a day. Our own AI visibility checker is free and shows the site issues that affect visibility.
How many prompts should I track?
Track the questions buyers ask before they choose a product like yours, across your main products or services. Small businesses can learn a lot from 25 to 50 prompts. Avoid filling your quota with brand-name prompts, which you will almost always win.
Do AI visibility tools improve visibility?
No, they measure it. Visibility improves when you change your site and content, for example by opening access to AI crawlers, adding schema and answering questions clearly. Some tools suggest those changes, and a service can make them for you.
Why do AI visibility scores change from day to day?
AI answers are generated fresh each time and can differ between runs, even for the same prompt. That is why daily tracking and trends over weeks are more reliable than a single check.
