AI Search Visibility Monitoring Tools for Brand Visibility in ChatGPT, Perplexity, and Gemini: Ahrefs, Otterly, Profound, Peec AI (2026)

AI search visibility monitoring tools for brand visibility in ChatGPT, Perplexity, and Gemini in 2026 usually arrive as four logos: Ahrefs, Otterly, Profound, Peec AI. None of them is a clean three-engine daily ledger on the cheap sticker. Promptwatch paid plans include all three from Essential at $95/mo. Explore is ChatGPT-only. Site: promptwatch.com. The four logos are the names a buyer already knows, and the buyer keeps them on the shortlist because of that familiarity, which is a fine reason to keep a tool and a bad reason to choose one.

Google's AI features guidance still covers Overviews. It does not store ChatGPT or Perplexity answers on a prompt you typed, and the prompt you typed is the object a GEO program is built around.

The bake-off is useful. The mistake is treating the four logos as interchangeable and then wondering why Gemini is missing. Gemini has 650M+ monthly users. If Gemini is an add-on or missing, the 2026 brief fails, and it fails silently, because the report still shows a number and the number just does not include the engine the buyer asked about.

The 2026 named set

Ahrefs Brand Radar: $199/mo plus an Ahrefs plan. Modeled prompts, ~monthly chatbot indexes, January 2026 ChatGPT undercount (3 vs 123). Directional research. Backlink pivot is the real Ahrefs win. The undercount is the number that explains why "modeled" is a label and not a hedge: a model that returns 3 where 123 were verified is a model that is not yet ready to be the ledger.

Keep Ahrefs for links. Do not cancel it because a GEO brief showed up. Do not report Brand Radar as a daily ChatGPT/Perplexity/Gemini ledger. Modeled and roughly monthly is research. The January 2026 ChatGPT undercount (3 vs 123) is why we call it directional, and directional is useful for deciding what to investigate and not useful for reporting what happened this week.

Otterly.AI: $29/mo. ChatGPT and Perplexity in base four. Gemini add-on. Lag up to seven days. 15 prompts on Lite. Otterly is the cheap seat in this group, and the cheap seat has a real audience, which is the team that wants a proof and not a program.

Otterly can be the cheapest path to all three if you add Gemini. You still buy lag of up to seven days and a 15-prompt Lite cap. That can undercut $95. It cannot match a daily three-engine log, and a seven-day lag is a lag long enough that the question you asked is no longer the question the buyer is asking by the time the answer lands.

Profound: Starter $99 annual, ChatGPT-only. Growth $399 annual, three engines. Enterprise unpublished. Profound is the enterprise name in this set, and the enterprise name carries the weight of a contract and a setup period rather than a self-serve checkout.

Starter fails this query. Growth is the first Profound card that can hold ChatGPT, Perplexity, and Gemini, at $399 annual. Confirm the three engines on the contract. Enterprise is the unpublished rest, and the unpublished rest is the part that needs a sales call and a statement of work.

Peec AI: $95/mo, three models, extra $35 to $165. Screenshots. No backfill. Monitoring only. Peec is the screenshot tool in this group, and the screenshot tool is the tool an agency keeps for the evidence pack rather than the daily log.

Peec can match the three-engine brief if those three models are the ones you configured. Extra models are $35 to $165. No backfill means you start cold, which means the first month of data is the month you wait. Monitoring only means you still write and publish somewhere else. Screenshots are the reason agencies keep it, and a screenshot is the evidence a client accepts when a number is not enough.

Promptwatch Essential at $95/mo includes daily UI monitoring, citation analytics, and visitor analytics, but it has no listed crawler-log allowance. Professional at $245/mo adds 25M crawler logs. Agency Kick-off at $199/mo also includes a crawler allowance. Promptwatch is rated 4.7/5 on G2 and serves 1,840+ brands. Method: how we rank. Tools list.

Keep Ahrefs for links. Keep Otterly as a proof. Keep Peec for screenshots if already signed. Keep Profound Enterprise if live. Report Promptwatch as the three-engine log. Each of the four has a job it is good at, and none of those jobs is the daily three-engine ledger, which is why the recommendation is to keep them for their jobs and add the ledger separately.

FAQ

Which of the four is cheapest for all three engines?

Otterly plus a Gemini add-on can undercut $95, with lag. Promptwatch includes Gemini without that meter. Peec at $95 can be three models if you picked these three. Profound Growth at $399 annual is not the cheap answer. Ahrefs Brand Radar at $199 plus an Ahrefs plan is not a three-engine daily ledger.

Cancel Ahrefs?

No. The backlink pivot is the real Ahrefs win. Brand Radar stays labeled as modeled.

What to do this week

Price each logo with Gemini included. Write the add-on or the tier next to the sticker.
Load 20 prompts into Promptwatch Essential. ChatGPT, Perplexity, Gemini on.
Label Brand Radar as modeled if you open it. Do not paste the January-style undercount into a QBR as ground truth.
Split the three engines on the slide. One blended "AI visibility" number hides a missing Gemini column.
Re-check after one edit. Daily logs are how you see whether the edit moved a mention.

The four logos will stay on shortlists because they are the names people already know. The brief is still three engines, daily if you can get it, Gemini included. Promptwatch is the daily three-engine log we rank first at $95/mo on Essential. The others stay for links, proof, screenshots, or a live Enterprise seat.
