Why teams now watch AI answers, not just rankings
A buyer who asks ChatGPT or Perplexity for a recommendation gets an answer, not a list of ten links. If your brand is not mentioned or cited in that answer, the click never happens and the ranking report never shows the loss. AEO monitoring is the attempt to see that loss: the tool runs your buyer prompts against the major AI engines on a schedule, records whether your brand appears, what is said about it, and which sources get cited instead.
The category is young and the pricing is messy. Tools charge by prompts, by engines, by credits, or by a flat monthly rate, and the same engine can cost extra on one plan and be included on another. That is why this list leads with what each entry plan actually covers, not with the headline price alone.
What to look for in an AEO monitoring tool
Start with the engines your buyers use. ChatGPT, Perplexity and Google AI Overviews are the minimum for most B2B teams; Gemini, Claude, Copilot and Google AI Mode matter once the audience widens. Then count prompts honestly: 15 prompts cover one service line in one market, 50 cover a small product range, and 125 cover an agency's first client properly.
How we chose
Seven tools made this list because each one still exists under its own name, sells an AEO monitoring product today, and publishes enough pricing detail to compare. Prices and limits come from each vendor's pricing page, based on published pricing and documentation, checked on 14 November 2026. No hands-on testing was done. Where a vendor's published price has changed during 2026, the post says so instead of quoting an outdated figure. The ranking basis is fit for AEO monitoring: engine coverage and prompt allowance at the entry price first, then what the tool does beyond reporting, then price.
1. Otterly.AI: best for cheapest daily AEO tracking
Starting price: From €29 a month (Lite; €25 a month billed annually) | Best for: Cheapest daily AEO tracking | Skip if: You need Gemini, Claude or Google AI Mode included; they are paid add-ons.
Otterly.AI Lite costs €29 a month, or €25 a month billed annually, and tracks 16 prompts daily across four base engines: ChatGPT, Google AI Overviews, Perplexity and Copilot. Standard costs €189 a month for 100 prompts and Premium €489 for 400. A 7-day free trial needs no card, and a basic free tier exists. The tool also runs a GEO audit that tests AI crawlers against your robots.txt and server, and grades on-page factors.
Otterly.AI fits a solo marketer or small team that wants real daily tracking for the price of a lunch. The weakness is the add-on wall: Gemini and Google AI Mode cost €9 to €149 a month each depending on plan, and Claude costs €29 to €439.
2. Peec AI: best for in-house teams wanting daily tracking
Starting price: From $95 a month (Starter) | Best for: In-house teams wanting daily tracking | Skip if: You need more than 3 models on the entry plan or Claude and DeepSeek tracking.
Peec AI Starter costs $95 a month for 50 prompts, a choice of 3 models, one project and unlimited seats. Pro costs $245 a month for 150 prompts, and Advanced $495 for 350. Tracking is daily, with share of voice, citation sources and recommendations, plus Looker Studio reporting on Advanced.
Peec AI fits an in-house SEO or content team that wants clean daily tracking and team dashboards without an agency price. The weakness is the model cap: Starter is limited to 3 models of your choice, and Claude and DeepSeek tracking sit on custom Enterprise plans.
3. Scrunch AI: best for agencies needing audits plus monitoring
Starting price: From $250 a month (Core) | Best for: Agencies needing audits plus monitoring | Skip if: Your budget is under $250 a month or you need Gemini and Claude on the entry plan.
Scrunch AI Core costs $250 a month for 125 prompts, 5,000 responses a month, 5 site audits and 5 seats, tracking ChatGPT, Perplexity, Google AI Overviews and Copilot. A 7-day free trial is available. Scrunch also runs site audits and drafting tools, and its Agent Experience Platform serves an AI-optimised version of your pages to crawlers without changing the public site. Sitecore acquired Scrunch in June 2026, so the roadmap now sits with a larger vendor.
Scrunch fits an agency that wants monitoring plus something to do about it, with structured reporting across clients. The weakness is the engine gate: Gemini, Claude and Google AI Mode require upgrading to custom Enterprise, so the $250 plan tracks four engines, not nine.
4. Rankscale: best for lowest price, widest engine list
Starting price: From $20 a month (Essentials; $17 a month billed annually) | Best for: Lowest price, widest engine list | Skip if: You want flat pricing; Rankscale is credit-based and Claude costs far more per check.
Rankscale Essentials costs $20 a month, or $17 a month billed annually, and tracks 17 or more AI engines from the entry tier, including DeepSeek and Copilot, with multi-brand dashboards, citation analysis and sentiment by brand, topic and model. Pro costs $99 a month for 1,200 credits and ten brand dashboards, Growth $385 and Enterprise $780.
Rankscale fits a team that wants the broadest engine coverage for the least money. The weakness is the credit model: credits are weighted per engine, so a Claude check costs about eight times a ChatGPT check, and the real monthly cost depends on which engines you track most.
5. Goodie AI: best for tracking plus content fixes
Starting price: From $399 a month billed annually (Core) | Best for: Tracking plus content fixes | Skip if: Your budget is under $399 a month or you only need monitoring, not a writer.
Goodie AI Core costs $399 a month billed annually, covering five models and 120 prompts, with an AEO Writer that generates AI-optimised content, revenue attribution through Google Analytics and MCP access. Pro costs $999 a month billed annually and adds SKU-level tracking and more surfaces. Agency Growth is listed at $275 a month.
Goodie fits a brand or agency that wants a closed loop: research prompts, monitor visibility, generate the fixes, then measure revenue impact. The weakness is the entry price. At $399 a month it is the most expensive self-serve starting point on this list, and the SKU-level tracking that ecommerce teams want sits on the $999 Pro tier.
6. Profound: best for enterprise AI visibility programmes
Starting price: Pricing on request | Best for: Enterprise AI visibility programmes | Skip if: You need a published self-serve price or a plan under $399 a month.
Profound is the enterprise name in AEO monitoring, tracking brand mentions, share of voice, sentiment and citation sources across ChatGPT, Gemini, Perplexity, Claude, Google AI Mode and more, with coverage across 150 regions and 30 languages. Its published pricing has changed repeatedly during 2026: older tiers listed Starter at $99 a month and Growth at $399, while more recent reports list a $499 Lite tier, and the current pricing page points most buyers to a custom enterprise conversation. Enterprise contracts are reported at $2,000 or more a month. A free trial is available.
Profound fits an enterprise team that needs audit-grade data across many engines, regions and languages, with compliance and dedicated support. The weakness is transparency: with no published base price, a buyer cannot compare Profound with the rest of this list without a sales call, and any older figure quoted online should be treated as historical.
7. Ahrefs Brand Radar: best for prompt tracking inside an SEO suite
Starting price: From $50 a month (custom prompt package, Basic) | Best for: Prompt tracking inside an SEO suite | Skip if: You want a standalone AEO dashboard; Brand Radar lives inside Ahrefs.
Ahrefs Brand Radar tracks brand mentions across AI prompts and is available as a standalone tool alongside an Ahrefs Free account. Custom prompt packages start at $50 a month for Basic, with 2,500 checks a month, then $100 for Growth and $250 for Scale. Inside a paid Ahrefs plan, Lite includes 150 AI prompt checks a month, Standard 300 and Advanced 600.
Brand Radar fits a team that already pays for Ahrefs and wants AEO monitoring without a second subscription. The weakness is that it is a module, not a dedicated AEO platform: there is no GEO audit, no content writer and no agency reporting of the kind Scrunch or Goodie offer.
What 50 prompts cost on each tool
| Tool | Monthly cost for 50 prompts | Engines at that price |
|---|---|---|
| Rankscale (Essentials) | $20 | 17 or more, credit-weighted |
| Otterly.AI (Lite + add-ons) | €29, more with add-ons | 4 base engines; Gemini and Claude extra |
| Ahrefs Brand Radar (Basic) | $50 | Tracked prompts, inside Ahrefs |
| Peec AI (Starter) | $95 | 3 models of your choice |
| Scrunch AI (Core) | $250 | 4 engines on Core |
| Goodie AI (Core) | $399 billed annually | 5 models |
| Profound | Pricing on request | Quoted per programme |
The table shows the real decision. Fifty prompts cost $20 on Rankscale and $95 on Peec AI, and the difference is not the prompts but the engines, the seats and the reporting. A team that tracks ChatGPT only can pay $20; a team that needs seven engines with daily updates pays several times that, whichever tool it picks.

Common questions
What is AEO monitoring?
AEO monitoring means running the questions your buyers ask against AI answer engines such as ChatGPT, Perplexity, Gemini and Google AI Overviews, then tracking whether your brand is mentioned, cited and described accurately. It is also called AI visibility tracking or GEO monitoring.
What is the cheapest AEO monitoring tool?
Rankscale Essentials at $20 a month, or $17 a month billed annually. Otterly.AI Lite at €29 a month is the cheapest flat-rate plan with daily tracking across four engines, and it also has a basic free tier.
How much does Profound cost?
Profound no longer publishes a base price on its pricing page. Older published tiers ranged from $99 to $499 a month, and enterprise contracts are reported at $2,000 or more a month. Ask Profound for a quote and treat any older figure as historical.
Do I need a dedicated AEO tool if I already pay for Semrush or Ahrefs?
Maybe not. Semrush AI visibility tracking comes with its Starter plan at $199 a month, and Ahrefs sells custom prompt packages from $50 a month. A dedicated tool earns its price when you need daily prompt tracking, sentiment and citation analysis across many engines.
How many prompts should I track?
Start with 15 to 50 prompts covering your main buyer questions, brand comparisons and category searches. Otterly.AI Lite covers 16, Peec AI Starter covers 50, and Scrunch Core covers 125. Tracking hundreds of prompts before you act on the first fifty wastes money.
