Best AI Search Monitoring Tools in 2026: 15 Tools Compared

An AI search monitoring tool asks ChatGPT, Perplexity, Claude, Gemini or Google's AI answers the questions your buyers ask, records whether your brand is mentioned and cited, and repeats that on a schedule so you can see the trend. Most lists rank these tools on features. This one compares the numbers that decide what you actually get each month: which engines the entry plan checks, how often it re-checks, how many prompts it allows, and what it costs. Every figure below was read off the vendor's own pricing or product page on November 4, 2026.

The monitoring table

Prices are the lowest paid plan that includes AI monitoring, billed monthly unless marked. Euro prices are printed as each vendor showed them to our checker; check the dollar price at checkout. "Not stated" means we could not find the figure on the vendor's own site. Profound's trial and Athena HQ's free tier are free ways to start, and are covered on their cards.

How often each tool re-checks, and why it matters

An engine can give a different answer to the same question on different runs. A tool that asks once a week sees one sample of that answer; a tool that asks daily sees seven. More samples make the trend steadier and catch a drop sooner. They also cost the vendor more, which is why cadence and prompt count trade against each other on every pricing page above.

The tools fall into four groups:

• Daily by default: Profound, Peec AI, Otterly, SE Visible, Semrush prompt tracking, Surfer AI Search Analytics, Frase, Analyze AI and Nightwatch.
• You choose: Rankscale (hourly to monthly, paid in credits) and Ahrefs Brand Radar custom prompts (daily, weekly or monthly per platform).
• Weekly or slower: Rankwise (7 or 14 days by engine), LLMrefs (at least weekly), Surfer's Standard content plan (weekly, ChatGPT only) and the Ahrefs Brand Radar index (monthly).
• Not stated on the vendor's site: Athena HQ and Scrunch.

Rankwise sits in the slower group on purpose. Its scheduler re-checks Perplexity, Claude and Google AI Overviews every 7 days and ChatGPT and Gemini every 14, because citation rates move slowly week to week and the two slower engines cost three to four times as much to query. That keeps the entry plan at $59 a month for 50 questions. If you need to see a change the day after you publish, pick a daily tool. If you want a steady weekly trend and the plan, drafts and fixes that follow it, Rankwise is built for that.

What to monitor, whichever tool you pick

1. Citation rate per question. The share of checks where the engine links to your site.
2. Mentions without a link. Being named without a citation is a separate result, and worth tracking on its own.
3. Which of your URLs get cited. If engines cite one old page for everything, that page is your leverage point.
4. Who gets cited instead of you. The competitor and the source (a review site, a forum, a list) tell you what to write or where to get listed.
5. Whether AI crawlers can read your site. If robots.txt blocks an engine's crawler, that engine can be stopped from reading the pages you want cited. Our free AI crawler checker tests this in one step.

Which tool fits your team

Agencies tracking many brands should compare prompt allowances first. Scrunch (350 custom prompts), SE Visible (75 prompts across 5 projects on Basic) and LLMrefs (unlimited projects) give the most room per dollar. Rankwise's agency plan is $299/month for three client workspaces, each with 100 questions per domain re-checked weekly, then $99/month per extra client. Rankwise sets agency accounts up by hand, so contact the team to start one.

In-house SEO teams already paying for a suite can start with the add-on they own: Semrush's toolkit at $99/month or SE Ranking's daily prompts in Core. Move to a dedicated tool when you need more engines or more prompts than the add-on allows.

Founders with no SEO team need the tool to do something after it measures. Rankwise turns uncited questions into a month of planned articles and publishes them to your CMS. Otterly at $29/month is the cheapest way to watch daily if you will do the writing yourself.

How we built this list

We read each vendor's pricing page and, where the pricing page left a number out, its product or help pages, on November 4, 2026. We recorded engines, re-check cadence, prompt limits and the entry price exactly as stated, and wrote "not stated" where the vendor does not publish a figure. We did not buy every plan, so the cards describe what each vendor says it sells. Screenshots are each vendor's homepage on the date shown under it.

Rankwise publishes this page and lists itself first. Its card states the same four numbers as every other card, and its cons name where it is behind: a slower re-check cadence than the daily trackers, three engines on Starter, and no prompt-volume data. Rankwise's cadence comes from its own scheduler code; its prices come from its live pricing page.
