Answer engine optimization tools: feature & pricing matrix

Answer engine optimization (AEO) tools measure and improve how AI assistants — ChatGPT, Perplexity, Claude, Gemini, and Grok — cite and recommend a brand when they answer buyer questions. As of August 2026 the category has real money and real spread behind it: Profound raised a $96M Series C at a $1B valuation in February 2026, and published self-serve pricing runs from $39/month (Frase Starter, accessed August 2026) to $800/month (Evertune Pro, accessed August 2026). This is a structured feature-and-pricing matrix for buyers comparing the main options — Profound, Evertune, AIClicks, Frase, and Data for AI Search — across price, model coverage, methodology, and whether the tool only measures visibility or also does the work to change it. Every figure is sourced to the vendor's own page with an access date, because a comparison matrix is only useful if its cells are verifiable.

What are answer engine optimization tools?

Answer engine optimization tools track whether AI assistants name and cite a brand, and most add some workflow to improve it. The measurement job is consistent across the category: submit a defined set of prompts to each AI model, then record whether the brand is cited as a source and named in the answer — two axes that come apart, as the 10-Point AI Citation Framework details. Where the tools diverge is everything around that measurement: how many models they cover, how deeply they sample, what they charge, and whether they stop at a dashboard or carry the buyer into content, entity, and authority work. The category overlaps with AI visibility and generative engine optimization; the terminology is disambiguated in AEO vs SEO vs GEO.

How do the leading AEO tools compare on price?

Published self-serve AEO pricing in 2026 spans roughly $39 to $800 per month, with every vendor reserving a custom-quoted enterprise tier. The matrix below lists each vendor's published entry price and top self-serve tier, sourced to the vendor's pricing page as of August 2026.

Enterprise pricing at Profound and Evertune is not published; third-party reviews estimate Profound enterprise deals in the low thousands per month, but the vendor does not state a figure, so it is an estimate rather than a fact.

Which AI engines does each tool track?

Model coverage clusters around a shared core — ChatGPT, Perplexity, Gemini, and Claude — with Grok, Copilot, and Google AI Overviews as the differentiators. The count matters less than which specific assistant matters to a given audience, and coverage is frequently gated by pricing tier.

Evertune tracks eleven models but does not list Grok (accessed August 2026), while AIClicks lists ten surfaces including Grok yet limits lower tiers to three or four models (accessed August 2026). The lesson for buyers: read the tier, not the marketing page.

How do the tools differ on methodology?

The methodology gap that most affects data quality is sampling depth — how many times a tool asks each model the same question before recording a result. Generative models return different answers to identical prompts, so a single sample reports variance as signal. Evertune samples each prompt 100 times across every model (accessed August 2026); Data for AI Search runs a multi-sample scan (K3 by default) and separates a confirmed citation from a one-off. AIClicks states it queries AI platforms through the consumer interface rather than APIs (accessed August 2026, vendor claim). Frase runs its AI-visibility checks daily on tracked prompts with alerts on movement (accessed August 2026). A tool that samples once per prompt, or does not disclose its sampling, should be read with that limitation in mind.

Which tools only measure, and which also do the work?

Most AEO tools measure visibility; a subset also carries the buyer into the work that changes it. This is the distinction that most explains the price spread, and it is unpacked fully in AI visibility trackers vs. a system that gets you cited.

Frase positions itself as "the content operating system for AI search" (accessed August 2026): its AEO tracking is real but bundled into a content-production workflow rather than sold as a standalone monitoring platform. Profound and Evertune layer content and advertising modules on top of enterprise-grade monitoring.

How should a buyer read this matrix?

A buyer should start from budget and the specific outcome wanted, then narrow by model coverage and whether the tool does the work or only reports it. A $59/month prompt tracker and an $800/month platform are not competing for the same job: one watches a number, the other bundles monitoring with content and optimization. The deeper segmentation — by budget tier and company size — is covered in the AI visibility tools buyer's guide, and the narrative head-to-head of the monitoring specialists is in Evertune vs Profound vs Frase vs AIClicks. The single question that cuts through the matrix: when the score is bad, does the tool do anything about it, or only tell you it is bad?

Frequently asked questions

What is the cheapest answer engine optimization tool? Among tools with published self-serve pricing in 2026, Frase starts lowest at $39/month (Starter, billed yearly), followed by AIClicks at $59/month and Profound at $99/month. Data for AI Search offers a free 10-point audit before any paid tier. Cheaper prompt trackers exist but typically cap model coverage and prompts sharply.

Which AEO tool covers the most AI engines? Evertune lists the most models at eleven, though it does not include Grok. AIClicks and Profound both cover Grok. Model coverage is often gated by pricing tier — AIClicks limits lower tiers to three or four models — so the tier matters more than the top-line count.

Do AEO tools do the optimization work or just measure it? It varies. Frase is content-first with tracking bundled in; Profound and Evertune add content and advertising modules on top of monitoring; Data for AI Search adds off-site authority, entity, and content work. Lightweight prompt checkers measure only. The distinction is the main driver of price differences across the category.

How do AEO tools get their data? Most submit a defined set of prompts to each AI model on a schedule and parse the responses for brand mentions and cited sources. They differ on sampling depth (Evertune samples each prompt 100 times; Data for AI Search runs multi-sample K3), on API-versus-interface querying, and on how many models they cover.

Is a feature matrix enough to choose an AEO tool? No. A matrix narrows the field on price, coverage, and capability, but the deciding factor is usually fit — budget, which assistant matters to the audience, and whether the buyer needs measurement only or measurement plus the work. Pair this matrix with the buyer's guide segmentation and a free audit before committing.
