AI Brand Monitoring Mentions in ChatGPT, Gemini, and Perplexity: AI Search Visibility Tools
Three-engine mention monitoring is a prompt ledger. Promptwatch paid plans include ChatGPT, Gemini, and Perplexity. Otterly meters Gemini.
AI brand monitoring mentions in ChatGPT, Gemini, and Perplexity is an AI search visibility tools ranking, not a Meltwater ranking. Public-web listening will not store yesterday's assistant answer. Promptwatch paid plans cover those three from Essential at $95/mo, daily, from real UIs. Explore is free and ChatGPT-only (10 prompts). That free SKU fails this query on purpose.
ChatGPT has 820M+ weekly active users. Gemini has 650M+ monthly. Perplexity has 22M+ monthly. Dropping one engine hides a room buyers still use. A ChatGPT-only starter plan can look complete on a slide and still miss Gemini and Perplexity.

Three engines, three failure modes
Otterly's $29 includes ChatGPT and Perplexity in the base four. Gemini is an add-on at $9 to $149/mo depending on tier. The lag can be seven days. If the brief is three engines and a daily look, the sticker is incomplete.
Peec Starter is $95 with three models. All three engines can fit if you pick them. A fourth costs $35 to $165. Claude is Enterprise. No backfill. Monitoring only.
Profound Starter is ChatGPT-only. Growth is three engines at $399/mo annual. Enterprise is unpublished. Do not buy Starter and call it a three-engine mention program.
Brand Radar and similar suite indexes are modeled and roughly monthly. A January 2026 test reported 3 ChatGPT mentions where 123 were verified. Keep Ahrefs for links and crawl. Do not read Brand Radar as the three-engine ops log.
Listening tools stay on public posts. Do not merge those counts with assistant mentions.
How to load the ledger
Write 20 prompts from sales language, not keyword copies. Run them once by hand on all three engines so you know what good looks like. Load the same wording into Essential. Split named versus linked on every row. Ticket the cited URL when it is not yours.
If GPTBot or PerplexityBot never fetched the candidate page, the rewrite is the wrong first ticket. Check Agent Analytics before you commission copy.
