What does an AI visibility tool do?

It asks AI engines the questions your buyers ask, stores the answers, and shows whether your brand and your competitors are named, in what position and with which sources cited.

Is there a free AI visibility tool?

Presence Scout has a free plan with 5 prompts and 10 keywords, and AthenaHQ's free Essential plan includes 300 credits. Presence Scout also has a free one-off AI visibility checker.

How many prompts do I need to start?

Twenty to fifty buyer questions are enough for most single brands. Cover the questions people ask before they know your name, not only searches for your brand.

Best AI Visibility Tools in 2026: 7 Trackers Compared

Seven AI visibility tools compared on price, prompts, engines and free options, read from each vendor's own pricing page, with who each one suits.

When someone asks ChatGPT or Google's AI Mode for the best tool in your category, are you in the answer? AI visibility tools exist to tell you. There are dozens now, so I read the pricing pages of seven of them and compared what you get at the starting price.

Full disclosure: I make Presence Scout, one of the seven, so I'm not neutral. Every figure comes from the vendor's own pricing page, linked below. Prices change, so check before you buy.

What to compare

Engines. ChatGPT, Perplexity, Gemini, Google AI Overviews and AI Mode are the five most people need. Some plans include fewer, or sell them as add-ons.
Prompts. How many buyer questions you can track, and how often they're checked.
The answer behind the score. Can you read the stored answer and the pages it cited? If not, you can't check the tool's numbers.
Google rankings. AI answers and search results influence each other, so seeing both together saves a second tool.

Prices read on each vendor's pricing page in October 2026, monthly billing.

1. Presence Scout: AI answers and Google rankings together

Presence Scout's Starter plan is $29 a month (₹2,499 in India) for 50 prompts and 100 Google keywords across 3 brands, on ChatGPT, Perplexity, AI Overviews and AI Mode. Growth, $99 a month, adds Gemini. The free plan covers 5 prompts and 10 keywords.

Your Google rankings, including the local map pack, sit next to the AI answers for the same topics, and every result links to the stored answer and its cited pages. Checks run weekly, by design, so the allowance covers more questions instead of re-asking a few daily.

2. Otterly.AI: daily checks on a small budget

Otterly.AI Lite is $29 a month for 15 prompts checked daily on ChatGPT, AI Overviews, Perplexity and Copilot. Gemini, AI Mode and Claude are paid add-ons. Standard is $189 a month for 100 prompts.

3. Knowatoa: many sites, one question list

Knowatoa Starter is $59 a month for ChatGPT, AI Overviews and AI Mode; Growth, $199, covers all seven services it tracks, including Claude, Gemini and Meta AI. You can add unlimited sites that share one question limit, and every plan gets a weekly digest of what changed.

4. Semrush AI Visibility Toolkit: if you already use Semrush

The AI Visibility Toolkit is $99 a month per domain for 25 prompts tracked daily, with mentions from ChatGPT, Google AI, Gemini and Perplexity, plus prompt research with topic volumes. Its help pages say the toolkit has no free trial. Google rank tracking comes in separate bundles from $199 a month.

5. Scrunch: preparing your site for AI agents

Scrunch Core is $250 a month for 125 prompts on ChatGPT, Perplexity, AI Overviews and Copilot, with 5 site audits a month. It also offers Agent Pages, versions of your site built for AI agents to read.

6. AthenaHQ: the most models, with a free start

AthenaHQ has a free Essential plan with 300 credits across five engines. Starter is $295 a month ($245 billed yearly) for 3,600 credits, where one credit is one AI response, across 11 models including Claude, Grok and DeepSeek.

7. Goodie: revenue attribution for larger brands

Goodie Core is $399 a month for 120 prompts collected daily on ChatGPT, AI Overviews, Perplexity, AI Mode and Copilot, in two countries, with 5 seats. It highlights direct revenue attribution and connects to Google Analytics and Search Console.
