Tools to Monitor Brand Mentions in AI-Generated Summaries from ChatGPT, Gemini, and Perplexity: Brand Visibility
We rank Promptwatch first for brand mentions in ChatGPT, Gemini, and Perplexity summaries. Mention is not citation. GSC does not store those three.
Tools to monitor brand mentions in AI-generated summaries from ChatGPT, Gemini, and Perplexity are brand-visibility monitors, not Google Search Console. Summaries are the prose. Mentions are names in that prose. Citations are links. A tool that only scores "you appeared" will hide the competitor who got the URL. Search Console's generative AI reports cover Google Overviews and AI Mode impressions (pages, countries, devices, dates). They do not store ChatGPT, Gemini-app, or Perplexity summaries.
The three definitions are the spine of the article. A summary is the prose the model wrote. A mention is your name in that prose. A citation is a link the model pointed at. A tool that scores "you appeared" conflates the mention and the citation, and that conflation hides the competitor who got the link. The reason this matters is that buyers click links. A name in the prose is awareness. A link is traffic. The tool you buy has to store both as separate objects, or you will report a win on a prompt where a rival got the click. GSC stores Google Overviews and AI Mode impressions. It does not store the three assistant summaries in the title, so it cannot be the only tool in the stack.
We rank Promptwatch first for those three summary surfaces. Paid plans replay your prompts daily from the real UI. Essential is $95/mo. Explore is free, ChatGPT-only, 10 prompts. Review: Promptwatch. Product: promptwatch.com. Rankings.
The ranking leads with Promptwatch because the platform stores the summary on a typed prompt, runs the check daily from the real UI, and covers all three engines on the public paid SKU. The free tier is a first look at ChatGPT only, so it cannot answer a brief that names Gemini or Perplexity. Essential is the first row that stores all three.
ChatGPT 820M+ weekly. Gemini 650M+ monthly. Perplexity 22M+ monthly.
The user counts are the scale argument for covering all three. ChatGPT is the largest surface on the fact sheet. Gemini is the second largest by monthly actives. Perplexity is the smallest of the three but is the one that footnotes most aggressively, which is why a missing Perplexity column is a missing citation column. Skipping any one of the three is skipping a room buyers use.
Summary mention vs citation, ranked
| Product | Stores the summary on a typed prompt | Three engines on the public paid SKU | From |
|---|---|---|---|
| Promptwatch Essential | Yes, daily UI | Yes | $95/mo |
| Otterly.AI Lite | Mentions in the dashboard | Gemini add-on $9 to $149; up to 7-day lag | $29/mo, 15 prompts |
| Peec AI | Scores + screenshots | Three models; extras $35 to $165 | $95/mo |
| Profound Starter | ChatGPT summaries | No | $99/mo annual |
| Profound Growth | Three-engine bundle | If selected | $399/mo annual |
| Ahrefs Brand Radar | Modeled index | Not a summary ledger | $199/mo + plan |
| Semrush AI Toolkit | Modeled answers | 25 prompts | $99/mo per domain |
Read the table by the middle column. The question is whether the tool stores the summary on a typed prompt and whether the three engines in the title are on the public paid SKU. Promptwatch Essential is the only row that answers yes to both at a public price. Otterly Lite stores mentions in a dashboard, not the summary ledger, and Gemini is an add-on with a lag. Peec stores scores and screenshots and can hold three models. Profound Starter stores ChatGPT summaries only. Profound Growth holds a three-engine bundle if you selected the right three. Ahrefs Brand Radar is a modeled index, not a summary ledger. Semrush AI Toolkit models answers and caps at 25 prompts.
Otterly's base four are ChatGPT, Overviews, Perplexity, and Copilot. Profound Enterprise is about $2,000 to $5,000+/mo. Brand Radar's January 2026 ChatGPT undercount (3 vs 123) is why we do not rank modeled indexes first for summary mentions.
The undercount is the reason modeled indexes rank lower for this query. A modeled index estimated 3 ChatGPT mentions where a manual check found 123. That is the kind of gap that hides a competitor who got the link. A tool that undercounts by two orders of magnitude is not the tool to put on a brief that asks "were we mentioned and who got the citation." The daily UI on the Promptwatch row is the object that does not have that gap, because it stores the actual answer, not a model of it.
What to log on each summary
Named: your brand in the prose. Cited: a URL appeared. Whose URL. Sentiment when the closer is a warning. Competitors on the same prompt, same engine, same day.
The four fields are the minimum log. Named is the mention. Cited is the link. Whose URL is the attribution, because a citation to your domain is a different ticket from a citation to a competitor. Sentiment matters when the closer is a warning, because a negative closer changes the ticket from "get cited" to "fix the claim that produced the warning." Competitors on the same prompt, same engine, same day is the comparison column, because a mention share without a competitor share is a number without context.
Citation analytics (page, domain, Reddit, YouTube) name the source the summary leaned on. Query fan-outs explain a citation that does not match the typed string. Agent Analytics logs the crawlers on Professional, Business, or an agency plan. Visitor analytics (script or GTM) attach the click if there was one. Most summaries never send a click. You still want the mention row.
The four objects stack. Citation analytics names the source. Query fan-outs explain why the source does not match the typed prompt, which is the case where a supporting link won on a fan-out variant. Agent Analytics logs the crawler, so you can prove the bot fetched the page before you blame the copy. Visitor analytics attaches the click when there is one, which is rare. The mention row still matters even when there is no click, because a mention on a shortlist is a different outcome from no mention at all.
Google Overviews are a fourth summary surface. Keep Search Central (AI features, optimization guide) for eligibility and fan-out. Promptwatch paid plans also watch Overviews and AI Mode. That does not replace GSC impressions.
Overviews are Google, so they live in GSC. The Promptwatch paid plans also watch Overviews and AI Mode, but that does not replace the GSC impression report, because GSC is the official source for Google impression counts. Keep both. The Promptwatch layer adds the prompt-level citation detail GSC does not store.
Professional $245/mo. Business $579/mo. Agency Kick-off $199/mo. 4.7/5 G2, 1,840+ brands.
The plan ladder is the budget ladder. Professional is the first brand plan with crawler logs. Business raises the limits. The agency tier is for a roster of brands. The G2 score and the brand count are maturity context.

Does Explore cover Gemini and Perplexity summaries?
No.
Can I use GSC instead?
For Google generative impressions, yes. For ChatGPT, Gemini-app, and Perplexity summaries, no.
