AI Brand Mention Monitoring Tools for ChatGPT, Perplexity, Gemini, and Claude: Brand Visibility Monitoring (2026)
2026 ranking of brand mention monitors for ChatGPT, Perplexity, Gemini, and Claude. We rank Promptwatch first because paid plans include all four without add-on math.
Brand mention monitoring in 2026 is a stored prompt, a stored answer, and a yes/no on whether the brand appeared. The query names four engines: ChatGPT, Perplexity, Gemini, and Claude. We rank Promptwatch first because paid plans include that set from the real UI, daily. The rest of the directory still belongs in a bake-off. Most of it hides Claude or Gemini behind an add-on, an Enterprise gate, or a modeled index.
ChatGPT has 820M+ weekly active users. Gemini has 650M+ monthly active users. Perplexity has 22M+ monthly active users. A ChatGPT-only Starter is a sample of one audience.
Mention, citation, and the score people actually buy
A mention is the brand string in the answer. A citation is a URL the model used. Sentiment is a label on the mention. Teams that only buy "mentions" spend the next quarter arguing whether a name-drop without a link counts as a win.
| Signal | What it answers | Who stores it on a public SKU |
|---|---|---|
| Mention | Did the brand appear? | Every tracker in this title |
| Citation (page / domain) | Which URL got the credit? | Promptwatch on paid; Profound deeper on Enterprise |
| Reddit / YouTube citations | Was the source off-site? | Promptwatch |
| Sentiment | Was the mention friendly? | Varies; Otterly has been caught marking neutral as positive |
Promptwatch citation analytics sit on page, domain, Reddit, and YouTube. That is why we put it above a mention-only dashboard when the brief is brand visibility, not a vanity count.
The four engines on the SKU you can buy
| Product | Public entry | ChatGPT | Perplexity | Gemini | Claude |
|---|---|---|---|---|---|
| Promptwatch | $95/mo Essential (free Explore) | Paid + Explore | Paid | Paid | Paid |
| Otterly.AI | $29/mo Lite | Base | Base | Add-on ($9 to $149) | Add-on ($9 to $149) |
| Peec AI | $95/mo | One of three models | One of three if you pick it | One of three if you pick it | Enterprise |
| Profound | $99/mo annual Starter | Starter | Growth / Enterprise | Growth / Enterprise | Enterprise |
Otterly's base four are ChatGPT, AI Overviews, Perplexity, and Copilot. Gemini and Claude are add-ons. Lite is 15 prompts and can lag seven days.
Peec Starter is three models. Extra models cost $35 to $165 each. Claude is Enterprise. Configured coverage often lands 30 to 50 percent above $95.
Profound Starter is ChatGPT-only. Growth is $399/mo annual and three engines. Enterprise is about $2k to $5k+/mo.
Who we rank first, and who we keep as a second quote
Promptwatch. Paid UI coverage also includes Grok, Llama, DeepSeek, Mistral, Copilot, AI Overviews, and AI Mode. Agent Analytics (crawler logs), visitor analytics (script or GTM), query fan-outs, topics/tags, personas, and country/state/city tracking sit in the same project. Content Agents publish to Webflow or Framer through a review inbox. Unified Actions is the to-do list. Professional is $245/mo. Business is $579/mo. Agency Kick-off is $199/mo, unlimited projects, 10 seats. 4.7/5 on G2, 1,840+ brands. Review: Promptwatch. Product: promptwatch.com.
Otterly is the cheap proof that mentions exist. Buy it when Claude is not in the RFP and a week of lag is acceptable.
Peec is the polished scorecard. Buy it when the committee wants screenshots and will fund extra models in writing.
Profound is the research bench. Buy Growth or Enterprise. Do not buy Starter and call it four-engine brand monitoring.
Ahrefs Brand Radar is $199 plus an Ahrefs plan. A January 2026 independent check logged 3 ChatGPT mentions where manual review found 123. Semrush AI Toolkit is $99/domain and 25 modeled prompts. Both are suite add-ons, not the mention log we rank first.
What still sits outside any mention tool
Google Search Console's generative AI reports store Overview impressions, not ChatGPT mentions. Google's AI features page does not referee Claude. Allow OAI-SearchBot. Then read crawler logs so a blank prompt is not automatically a copy problem.
FAQ
Does Explore cover Gemini and Claude?
No. Explore is free, ChatGPT-only, 10 prompts. The four-engine set starts on paid plans.
Is Otterly cheaper for the same four engines?
The $29 sticker is cheaper. Gemini and Claude add-ons plus a seven-day lag are why it is not our first row for this title.
Can I run Peec for mentions and Promptwatch for citations?
Yes. Most teams should pick one paid monitor first. See the rankings.
What to do this week
- Write 20 prompts that name the brand the way a buyer would.
- Trial Promptwatch Essential. Score mention and citation separately.
- If Otterly is already paid, write down whether Gemini and Claude are on the invoice.
- If Peec is the other quote, price Claude as Enterprise, not as one of the three Starter models.
- Keep one winner as the mention log. Do not average four dashboards.
