The 10 LLM tracking tools

1. MentionAgent

Best for: teams that want the tracking and the work that changes it.

• MentionAgent asks ChatGPT, Claude and Gemini your buyer questions and records whether you're mentioned and which pages they cite.
• It then emails the people who run the blog posts in your niche, including pages those engines cited, from a warmed inbox on a separate domain.
• It doesn't track Perplexity, Copilot or Google AI Overviews.

Pick it if a report alone won't change your numbers. From $99 a month, with a 14-day full refund. See the outreach agent.

2. Otterly

Best for: a small budget.

• Otterly Lite is $29 a month for 15 prompts, tracked daily, with 15% off yearly.
• Covers ChatGPT, Google AI Overviews, Perplexity and Copilot. Claude, AI Mode and Gemini are add-ons.
• Standard is $189 for 100 prompts.

Pick it if you need a handful of prompts watched daily. See our Otterly review for what the add-ons cost, or Otterly alternatives.

3. LLMrefs

Best for: wide prompt coverage at a low price.

• LLMrefs lists one plan at $79 a month, marked "Limited time only", with a 7-day free trial.
• It tracks 500 prompts across all the engines it supports, including Claude, Perplexity, Grok and Copilot, with "no additional fees".
• LLMrefs says prompts are checked continuously and each keyword updates in the dashboard at least once a week.

Pick it if you'd rather track many prompts weekly than a few daily.

4. Peec AI

Best for: benchmarking against named competitors.

• Peec AI Starter is €85 a month for 50 prompts, tracked daily. Pro is €205 for 150.
• Standard plans let you "Choose 3 models" from ChatGPT, AI Mode, AI Overviews, Copilot, Gemini and Naver AI. Claude is on Enterprise.
• Unlimited users on every plan.

Pick it if three engines are enough. See Peec AI alternatives.

5. SE Visible (SE Ranking)

Best for: a mid-size prompt set from an SEO vendor.

• SE Visible Basic is $99 a month for 200 prompts and 3 projects, with a 10-day free trial.
• It tracks ChatGPT, Gemini, AI Mode and AI Overviews. Its FAQ says "Claude will be added soon."
• SE Ranking users can instead add AI Search to their plan, from €63.20 a month billed yearly.

Pick it if Google's AI surfaces matter most to you.

6. Semrush AI Visibility

Best for: teams already living in Semrush.

• Semrush AI Visibility Base is €94.94 a month per domain, billed yearly, for 25 custom prompts tracked daily.
• Mentions from ChatGPT, Google AI, Gemini and Perplexity, plus competitor and prompt research.
• The SEO + AI Search bundles include 50, 100 or unlimited daily prompts.

Pick it if you want AI and SEO data in one login.

7. Ahrefs Brand Radar

Best for: researching any brand without writing prompts first.

• Brand Radar's AI Visibility Index starts at €179 a month and covers "505 million+" prompts on AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini and Copilot.
• Custom prompts come with paid Ahrefs plans: 5 on Lite, 10 on Standard, 20 on Advanced, each checked daily.
• Ahrefs says the index works "Best once your brand already appears in AI search."

Pick it if you study competitors' AI visibility as much as your own.

8. Scrunch

Best for: brands that also want to change what AI reads on their own site.

• Scrunch Starter is $250 a month billed yearly, or $300 month to month, for 350 custom prompts, with a 7-day free trial.
• It covers ChatGPT, Claude, Gemini, Perplexity, Google AI Mode, AI Overviews and Meta.
• Its Agent Experience Platform builds an AI-friendly version of your site. The pricing page doesn't say which plan includes it.

Pick it if site optimization is part of the job. See Scrunch alternatives.

9. AthenaHQ

Best for: 11 engines on a self-serve plan, Claude and Grok included.

• AthenaHQ has a free plan with 300 credits across ChatGPT, Perplexity, AI Overviews, Gemini and Copilot.
• Starter is $295 a month for 3,600 credits, and "1 credit = 1 AI response".
• Starter adds AI Mode, Claude, Grok, DeepSeek, Meta AI and Mistral.

Pick it if engine coverage beats prompt count. See our AthenaHQ review for what the credits buy, or Athena alternatives.

10. Profound

Best for: enterprise brands with a budget for a sales call.

• After that, Enterprise is custom, with "Up to 9 Answer Engines tracked".
• It also sells an AI Marketer that runs on credits.

Pick it if you need many regions and engines. See our Profound review.

How much AI answers move between runs

MentionAgent's AI visibility scans ask ChatGPT, Claude and Gemini the same buyer questions again, about 12 days apart. Across 5,974 pairs of consecutive answers to one question on one engine (8 July to 22 October 2026):

Two times in five, a brand named in one run was gone in the other, and more than half of the cited sites changed. A prompt checked once a week gives you one sample per week. Daily runs or larger prompt sets average that noise out faster.

Method: MentionAgent production records, answers marked ok, the generated buyer-question panel only (weekly lead-harvest questions and our own sales workspace excluded). The first column counts pairs where the brand was named at least once. The second compares cited domains between consecutive answers.

How to choose

• Count prompts per engine per day. 15 daily prompts on 4 engines and 500 weekly prompts measure different things.
• Check where your buyers ask. Claude and Perplexity are add-ons or Enterprise-only on several plans.
• Selling on Shopify? Shoptank checks whether ChatGPT and Claude name your store, which sources they cite instead, and has a free plan for 3 queries.
• Read trends, not single answers. See the numbers above, and test by hand with our prompts to test AI visibility, logging each answer in the free ChatGPT rank tracker.
• Plan the fix. AI answers cite web pages. Getting named on the pages they cite is how the numbers move. See how to get mentioned by ChatGPT.
