Generative engine optimization tools, by the job they do

Every roundup in this category lists the same monitoring products against each other. This one starts from the work instead, and the interesting result is which parts of it nobody sells a tool for.

Generative engine optimization is four jobs, and the tool category sells one of them well. Of the 12 products here, 12 measure whether you are named in AI answers, 1 is built to check whether engines can read your pages at all, 1 genuinely change the pages, and none earns the third party corroboration that most of what an assistant says about you comes from.

We are on this list, so read it that way

We sell a competing product, and in the table below ours is the only full mark in the retrieval column. That is the exact shape of a comparison written to flatter its author, so three things are worth saying plainly rather than in a footnote.

The four way split is our reading, not a measurement. Somebody else could reasonably divide this work into three jobs or five. What is not a reading is the data underneath it: the crawler blocking figures come from a published crawl of 1048 sites with the CSV attached, and the tool scores come from running our engine against each vendor's own page on a stated date.

The reasoning for every row is published, including ours. Each product gets one line saying why it is marked the way it is, so a vendor who disagrees has a sentence to argue with rather than a tick to resent.

The list is ordered by price, never by score. Cheapest first puts our row in the middle rather than at the top, which is where it belongs on a page we wrote.

The four jobs, in the order they have to happen

The order matters more than the list. Each job depends on the one above it, so buying for job 2 while failing job 1 is the most expensive mistake available in this category.

Retrieval

Can an engine fetch and read your pages at all?

Barely served

Crawler access per bot, whether the page survives without JavaScript, whether it is indexable, and whether the passage worth quoting is inside a directive telling engines not to quote it. Nothing later in the pipeline can recover from a failure here, because a page that was never fetched was never a candidate.

This is also where the failures actually are. When we crawled 1,048 of the most visited websites in August 2026, 28.3% blocked at least one AI crawler against 1.5% blocking Googlebot, and 145 of them blocked a crawler that feeds live answers rather than training. Most of those are accidents inherited from a robots file nobody has read in two years.

Measurement

Are you named in the answers, and who is named instead?

Well served

A fixed prompt set, put to each engine separately, rerun on a cadence, recording whether you were named, whether you were linked, and which competitors appeared in your place. Per engine rather than blended, because an average across four assistants hides the only finding worth acting on, which is that one of them cannot see you.

This is what the category is. Almost every product below is a monitoring product, and the good ones are genuinely good at it. It is also the job that tells you the least about what to do next, because knowing you are absent is not knowing why.

Fixing

Can the pages be changed so they can be quoted?

Thinly served

Restructuring so each section answers one question in a passage that can be lifted whole, adding the dates and the attribution that let a model tell how current a claim is, and making the mechanical repairs that retrieval turned up. Mostly editing rather than writing, and the highest return hour in the work.

A handful of products generate rewrite suggestions. Very few make the change on your live site, which is the part that costs time. Read carefully what a tool means by fixing: recommending an edit and shipping an edit are separated by everything difficult.

Corroboration

Do pages you do not own describe you correctly?

Not served at all

Assistants assemble most of what they say about a company from third party sources: directories, reviews, comparison pages, press. Being described wrongly on somebody else's page is a problem no amount of work on your own site fixes, and being described nowhere is worse.

Nothing in this category sells this, and it is not an oversight. It is people work, not software: getting listed, getting reviewed, getting written about. The tools that come closest report which sources an answer drew on, which tells you where the problem is without doing anything about it.

Job 1 is the one with numbers behind it. In our August 2026 crawl of 1048 of the most visited websites, 28.3% blocked at least one AI crawler against 1.5% blocking Googlebot, and 11 sites published an llms.txt while blocking an AI crawler in the same robots file. The study publishes the method and the data.

Which tool covers which job

Cheapest first. Prices were read on each vendor's own pricing page on 2026-08-06, and one row says "not published" because that is what the page said.

Why each row is marked that way

HubSpot AI Search Grader: A one off snapshot rather than a monitor, so it answers job 2 once and nothing else. Still the right first move at zero.
Visibility100x: Ours. Built on job 1, which is why it is the only full mark in that column, and on service plans the fixes get shipped. Read that column knowing who wrote it.
Rankscale: Tracking across eight engines with page audits bundled, so it reaches into jobs 1 and 3 without being built for either.
Otterly.AI: Prompt tracking across four engines, and deliberately nothing else. The cleanest single job product here.
Knowatoa: Citation and sentiment monitoring across every market. Sentiment is a genuine addition to job 2 rather than a fifth job.
Writesonic: Ten platforms tracked plus an agent that rewrites pages, which makes it one of the two products here that genuinely does job 3.
Profound: The enterprise end of monitoring, with agent analytics on top. Wider coverage of job 2, not a different job.
Semrush: AI visibility inside an SEO suite, so the site audit beside it covers some of job 1, though it was built for classic search.
Ahrefs Brand Radar: Measures against a large prompt database, and its backlink side is the closest anything here gets to job 4, though it reports rather than earns.
Athena: Nine models tracked with a content agent on top, so it recommends into job 3 without shipping the change.
Scrunch AI: Persona based monitoring across seven surfaces. Several prompt sets rather than one, which is depth in job 2.
Peec AI: Six engines with multi project reporting for teams running several brands. Monitoring, at agency shape.

Prices, tiers, the exact URL we scored and the checks each vendor's own site failed are on the priced comparison, which is the same dataset sorted for a buyer rather than for the work. One finding from it belongs here too: all 11 of the 11 vendor pages we scored failed the freshness signals check, on sites selling AI visibility. The wider evidence base for all of this, with samples and dates attached, is on the statistics page, and if you are still deciding which acronym you are buying, AEO against GEO is the short answer.

The job nobody sells, and why that is not an oversight

Only 1 product here does anything about corroboration, and the one that comes closest reports where your mentions are rather than earning any. That looks like a hole in the market until you notice what the job is: getting listed in the directories your buyers are compared in, getting reviewed where reviews are read, and getting written about by somebody who is not you. None of that is software.

It also happens to be the half that decides most outcomes. Roughly 85% of the brand mentions we see in AI answers come from pages the brand does not own, which means a company can fix every page it controls and still be described by whatever a stale comparison article said about it in 2024.

The practical version: measure it with the tools, because they do tell you which sources an answer drew on, then act on it with people. If a vendor tells you their platform does job 4, ask which specific third party page they will get you onto and by when.

Choosing, in the order that saves the most money

01
Check retrieval before buying anything
Free, about a minute, and it decides whether any subscription could work. The AI crawler checker and the render gap checker cover the two failures that account for most of it.
02
Establish that you have a problem, at zero
A free snapshot tells you whether assistants name you today. If they do, and you are retrievable, you may not need a monitoring subscription this quarter at all.
03
Buy monitoring for the engines your buyers use
Entry tiers start at $20 a month. Count engines and seats before comparing headline prices: one plan here tracks a single engine, and another includes unlimited team members on its cheapest tier.
04
Separate recommending a fix from shipping one
Two products here generate rewrites. Whether anyone applies them to your live site is a different question, and it is the one that determines whether the subscription changes anything.
05
Budget for job 4 as people, not software
Whatever you spend on monitoring, the corroboration work is the half that moves the outcome and no tool on this page does it.

Questions people ask about GEO tools

What are generative engine optimization tools?

Software for getting a brand named in AI generated answers. In practice the category is overwhelmingly monitoring: 12 of the 12 products reviewed here put a fixed prompt set to the assistants and report whether you were mentioned. The other three jobs GEO consists of, checking that engines can read your pages at all, changing the pages, and earning third party corroboration, are served much more thinly or not at all.

What is the best generative engine optimization tool?

The question has no single answer because these products do different jobs. If you have not established that you have a problem, start with a free snapshot and spend nothing. If you need ongoing monitoring, the entry tiers begin at $20 a month. If your pages cannot be fetched or rendered in the first place, no monitoring product fixes that, and it is the most common failure by a wide margin.

Do I need a GEO tool at all?

Not to start. The first job is mechanical and free to check: whether the AI crawlers are allowed in, whether your pages survive without JavaScript, whether the passage worth quoting is indexable. Those decide whether anything else can work, and they need a checker rather than a subscription. Buy monitoring once you know you are retrievable and want to watch what happens.

How much do generative engine optimization tools cost?

Entry tiers run from free to $300 a month across the 11 vendors here, with the enterprise tiers mostly quoted rather than published. Read what an entry tier covers before comparing two of them: one $99 plan on this list tracks a single engine, and the comparable plan against the rest of the category is four times that.

What is the difference between GEO tools and AI visibility tools?

Mostly the name. The same products are sold under both labels and the vendor usually picks the phrase their buyers type. Where the two genuinely diverge is scope: AI visibility describes the outcome being measured, and generative engine optimization describes the whole discipline including the work that changes the outcome, which is why a page listing only trackers under the GEO name is describing a quarter of the field.

Can a GEO tool get me into ChatGPT answers?

No product places you in an answer, and any that says it does is selling something that does not exist. What tools do is measure whether you appear, and in a few cases suggest edits. The placement itself comes from being retrievable, being the clearest available answer to a narrow question, and being corroborated on pages you do not own.

How were these tools scored?

We ran our own audit engine, the same 36 checks the free audit runs, against each vendor's own product page on 2026-08-06. The score describes that one page rather than the quality of the product behind it, and the exact URL scored is published on our AI visibility tools comparison so any of it can be rerun, including against us.

Start with the job that costs nothing to check

The free audit runs 36 checks on your live pages, including per bot crawler access and what a crawler without JavaScript receives. That is job 1, and it is the one that decides whether the rest is worth buying.
