Best LLM Brand Monitoring Tools (2026): Track Mentions in ChatGPT

The best LLM brand monitoring tools in 2026 are Mentionova, Peec AI, Otterly.AI, Semrush, SE Ranking, Surfer and Ahrefs Brand Radar. Mentionova is #1 because it goes past “were we mentioned”: it scores the sentiment of every answer that names you, checks claims against brand facts you set, and alerts you when an engine gets something wrong. Starter is $99 per month billed annually.

Sources: official pricing and product pages, fetched October 4, 2026. “Not listed” means the feature was not on the pages we fetched, not that it does not exist.

How did we pick these brand monitoring tools?

We looked for tools that monitor what large language models say about a brand: mentions, sentiment, competitors named beside you and the sources behind each answer. Then we ranked them on engine coverage, whether they flag inaccurate claims, and price. All facts come from vendor pages fetched on October 4, 2026.

Our rules:

1. Brand monitoring first. The tool must track named-brand mentions in AI answers on a schedule.
2. Official pages only. Every price and feature is from the vendor’s own site.
3. Ranking is editorial. We did not run the same prompt set through every tool, so the order is our judgment of fit.
4. Gaps are labelled. If a feature was not on the fetched pages, the table says “Not listed”.

What are the best tools to track brand mentions in ChatGPT and other LLMs?

The seven picks below are ordered by how well they cover the full monitoring job.

1. Mentionova: best LLM brand monitoring tool overall

Why it’s #1: Mentionova’s brand monitoring reads every answer that mentions you across six engines, scores the sentiment, checks the claims against your brand facts and alerts you when something is wrong, such as an engine quoting last year’s pricing. Its tracker logs who got named, where your page placed among the cited sources, and who was named instead.

• Best for: brands where a wrong AI answer about pricing or features costs deals.
• Price: Starter $99/mo billed annually ($125 monthly; 25 prompts, 3 engines), Scale $320/mo billed annually ($400 monthly; 100 prompts, 6 engines), Enterprise $799/mo billed annually ($999 monthly; 250 prompts).
• Engines: ChatGPT, Perplexity, Claude, Gemini, Google AI Overviews and Reddit on Scale and Enterprise.
• Trade-off: tracked questions run weekly, and Starter covers 3 engines.

2. Peec AI: best for daily tracking with unlimited users

Verdict: Pick Peec AI if you want a daily view of visibility, position, sentiment and share of voice against competitors. Starter is $95/mo with 50 prompts, 3 models and unlimited users.

• Accuracy features: Peec lists “prompts fact-checked”, where tracked answers are checked against facts you set, plus an Objections view of recurring arguments AI raises against your brand.
• Price: Starter $95/mo, Pro $245/mo, Advanced $495/mo, Enterprise custom.
• Trade-off: 3 models per plan unless you pay for more.

3. Otterly.AI: best low-cost brand tracker

Verdict: Pick Otterly.AI if you need daily brand tracking for less. Lite is $29/month for 15 prompts on ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot, with a Brand Visibility Index and link citation analysis.

• Price: Lite $29/mo, Standard $189/mo, Premium $489/mo, Enterprise custom.
• Trade-off: 15 prompts is a small sample for most brands, and Claude and Gemini are add-ons.

4. Semrush AI Visibility: best for sentiment inside an SEO suite

Verdict: Pick Semrush if you want brand sentiment next to your SEO data. Its AI toolkit benchmarks the positive and negative sentiment of your brand mentions and shows gaps in how each AI platform perceives you. AI Visibility Base is $99/mo per domain billed annually with 25 custom prompts.

• Engines: mentions from ChatGPT, Google AI, Gemini and Perplexity.
• Trade-off: 1 domain for Brand Performance analysis on Base.

5. SE Ranking AI Search: best add-on for SE Ranking users

Verdict: Pick SE Ranking’s AI Search add-on if you already use SE Ranking. It costs $89/mo ($71.20 billed annually) for 200 prompts across AI Overviews, AI Mode, Perplexity and ChatGPT, and includes SE Visible, a dashboard for brand mentions, citations and sentiment trends.

• Trade-off: it is an add-on, so you also need an SE Ranking plan (Core from $129/mo, or $103.20 billed annually).

6. Surfer AI Search Analytics: best for content teams

Verdict: Pick Surfer if your content team wants mention gaps it can write against. AI Search Analytics is 82 USD per month billed yearly for 50 prompts refreshed daily, with Mention Gap and Brand Sentiments and 5 brand spaces.

• Trade-off: it tracks ChatGPT, Gemini, AI Overviews and other models, but the pricing page does not list every engine by name.
