Best AEO tools in 2026: answer engines covered, and what each one costs

Answer engine optimization is measured on one thing: whether an assistant names you when someone asks it a buying question. This page compares the tools that measure it, on facts each vendor publishes, read on 2026-08-18.

Epovest is one of them. The table is ordered by published entry price, ascending, and carries no score: on a subject where every vendor grades itself, the only defensible order is a number the vendor published before we read it.

What counts as an AEO tool here

The tools listed are the platforms the six engines name or cite when our panels ask this market's buying questions, measured weekly in English and French, every answer archived (the method is here). They are not a hand-picked shortlist, which is why some names below are unfamiliar and some famous ones are absent.

An AEO tool, as the vendors themselves use the category, does three things in some proportion: it asks engines the questions your customers ask, it counts who gets named and from which sources, and it points at what to change. The table separates the first two, which are measurable, from the third, which every vendor words differently.

The comparison

"Not specified" describes the vendor's public pages on the read date, and nothing about what the product does. A vendor who publishes the missing fact gets the row updated, with the date.

Reading the engine count

A count is a list, not a guarantee. Two things sit behind it, and both are in the rows above.

Which engines a plan actually runs. AEO Vision names five and tracks one at its $9 tier. Ayzeo includes ChatGPT and Google AI Overviews at $39 and sells Claude, Perplexity, Gemini, DeepSeek and Grok at $29 per month each. Profound's published tiers restrict coverage below the enterprise plans.

How the answers are obtained. An engine can be queried through its official API, or approximated some other way. Epovest states the first for its six engines, which is what makes an answer reproducible and archivable with its sources.

What each tool is, per its own pages

Epovest asks your market's questions to six engines through their official APIs, at your rhythm from daily to monthly, and archives every answer with its cited sources, so any rate traces back to raw text. There is no subscription: credits are debited only by the surveys that run, at $0.10 per prompt, per engine, per survey, with a $10 minimum top-up and no expiry. The Atlas ranks the sources those answers lean on, which is the part of AEO that says where to appear rather than how you scored. The REST API and MCP server ship with every account, so your own assistant can read and drive all of it.

Siftly publishes a free tier at 100 tracked responses per month, then counts everything in tracked responses rather than prompts, up to $599.

Ayzeo prices per project, one included at $39 per month, and sells engines as add-ons at $29 each.

Omnia publishes from EUR 63 per month with credit packs sold separately, and pushes optimised content to your CMS.

Peec AI and Geneo run on subscriptions whose amounts were not published on the pages read on 2026-08-18.

Three questions before you pick one

Which engines answer your customers? Coverage counts only where your buyers ask. A European market where Mistral answers, or a developer market where Claude does, is not served by a tool watching ChatGPT alone.

Can you show the answer behind the number? An AEO rate is an aggregate of individual answers. Where those answers are kept, the rate can be checked, and so can a change over time.

Who reads the tool? If your own assistant is meant to read the data and act on it, look at where each vendor puts API and MCP access: some ship both to every account, others place them in upper tiers.

Method

Selection: the platforms named or cited by ChatGPT, Claude, Gemini, Perplexity, Mistral and Grok on this market's buying questions, measured on our own panels, weekly, in English and French, every answer archived with its sources. No tool was added or removed by hand.

Facts: read on each vendor's public pricing and product pages on 2026-08-18. Base prices only; promotional discounts are ignored. "Answer engines named" counts the engines a vendor names on those pages; where a plan restricts them, the restriction is in the row.

Order: published entry price, ascending, at its nominal amount in the currency the vendor publishes, then the tools whose price is not published. The page contains no score and no ranking.

Corrections: a vendor who publishes a missing or changed fact gets the row updated with the read date, logged here.
