Otterly AI to Monitor Brand Mentions in ChatGPT, Perplexity, and Gemini
Otterly monitors ChatGPT and Perplexity in the $29 base four. Gemini is an add-on. We rank Promptwatch first for daily mentions of all three without add-on math.
Otterly.AI will monitor brand mentions in ChatGPT and Perplexity on Lite at $29/mo. Those two sit in the base four engines with AI Overviews and Copilot. Gemini is not in that box. Gemini (and Claude, and AI Mode) are paid add-ons at $9 to $149 depending on tier. We still rank Promptwatch first when the brief is daily mentions across ChatGPT, Perplexity, and Gemini on one invoice. See the directory. The reason is the add-on math. A $29 base that charges extra for the third engine is not a $29 three-engine program, and the brief that names three engines is the brief that the $29 card does not cover.
Lite is 15 prompts and can lag up to seven days. That is a real mention proof. It is not a three-engine daily log. The distinction between a mention proof and a daily log is the one to keep. A mention proof answers "do we show up at all." A daily log answers "did we show up today, and did the number move since we changed the page." Otterly Lite does the first. It does not do the second.

The table reads as a story about two different products. Otterly Lite gives you two engines on a seven-day clock for $29. Promptwatch Essential gives you the full engine set on a daily clock for $95. The price gap is real. So is the coverage gap, and the coverage gap is the one that matches a three-engine brief.
Otterly Standard is $189/mo (100 prompts, API, Looker). Premium is $489/mo. Extra prompts on Lite-class usage run $99/mo per 100. Unlimited seats. No PDF export. No traffic or revenue attribution. Sentiment has been caught marking neutral mentions positive. No-card trial exists. The sentiment point is the one to remember when you read an Otterly mood chart. A neutral mention scored positive is a positive number that is not positive, and a program that reports sentiment without checking it is a program that reports a mood it did not verify.
ChatGPT 820M+ weekly. Gemini 650M+ monthly. Perplexity 22M+ monthly. A Gemini-shaped mention program that never pays the add-on is a two-engine program. The three user counts are the scale argument for why the third engine matters. A program that skips Gemini is a program that skips 650M monthly users, and that is a choice, not a saving.
Why we still send Promptwatch first
Essential includes Gemini without a second line item, plus Claude, Grok, Llama, DeepSeek, Mistral, Copilot, AI Overviews, and AI Mode, from the real UI, daily. Citation analytics (page, domain, Reddit, YouTube) turn a mention into a URL. Visitor analytics is available through a script or GTM. Essential also has topics/tags, personas, country targeting, query fan-outs, and 5 AEO articles. Professional adds Agent Analytics with 25M crawler logs plus state and city targeting. Promptwatch also offers Unified Actions. The citation analytics step is the one that changes the value of a mention. A mention is a name. A citation is a URL. The URL is what sends the visit, and the URL is what you can optimize for, so the platform that stores the URL is the platform that lets you act.
Professional $245/mo. Business $579/mo. Kick-off $199/mo, unlimited projects, 10 seats. 4.7/5 G2, 1,840+ brands. Review: Promptwatch. Product: promptwatch.com.
Use Otterly when you need a cheap ChatGPT + Perplexity screenshot this week and Gemini can wait. Use Promptwatch when Gemini is in the sentence you typed into Google to find this post. The sentence the buyer types is the better guide than the sticker price, because the sentence tells you which engines the program has to cover.
Other mention tools people add to an Otterly bake-off
Peec AI at $95 can hold ChatGPT, Perplexity, and Gemini if you spend the three Starter model slots on them. Extra models are $35 to $165. Claude is Enterprise. The three-slot constraint is the thing to price. Three engines at $95 sounds like a deal until you need a fourth, and the fourth is where the model slots run out.
Profound Starter at $99 annual is ChatGPT-only. Growth at $399 annual is three engines. Enterprise is about $2k to $5k+/mo. Profound sits below the dedicated AI-search platforms on this directory because the self-serve tier is narrow and the full product is Enterprise, and a three-engine brief on Profound means Growth, not Starter.
Scrunch AI from $250 annual refreshes weekly. Semrush AI Toolkit is $99/domain and 25 modeled prompts. Ahrefs Brand Radar is $199+plan; a January 2026 check logged 3 ChatGPT mentions vs 123 manual. The Ahrefs undercount is the reason we do not treat Brand Radar as a mention log, and the Semrush modeled-prompt count is the reason we do not treat the Toolkit as a daily log. Both are useful for different jobs and neither is the three-engine daily program.
Search Console generative reports are Overview impressions. They do not monitor Gemini-app mentions. GSC is the Google appendix, not the assistant log, and a program that reports Overviews impressions as AI visibility is reporting one engine as if it were the category.
FAQ
Is Gemini included in Otterly's $29 plan?
No. ChatGPT and Perplexity are. Gemini is an add-on, priced $9 to $149 depending on tier. A three-engine brief on Lite is a brief that pays the add-on or stays a two-engine program.
Should I keep Otterly after buying Promptwatch?
Optional as a second glance. Report Promptwatch as the mention log if Gemini and daily refresh are required. A second glance is fine. A second source of record is not, because two mention counts on the same prompt produce a meeting about which count is right, not a decision.
Is Otterly's lag a problem for mentions?
It is a problem if you changed a page on Monday and the dashboard still shows last week's miss. Fine if you are proving that mentions exist at all. The lag is a feature for the proof job and a bug for the iteration job, and which one you are doing decides whether the lag matters.
What to do this week
- Take Otterly's no-card trial if you have never seen a mention dashboard. Use 15 ChatGPT + Perplexity prompts.
