Best answer engine optimization (AEO) tools in 2026: free and paid

Answer engine optimization, or AEO, is the work of making your pages easy for search tools and AI assistants to quote. AEO tools help with the part you cannot see by looking at your website alone: what ChatGPT, Perplexity, Gemini, Copilot and Google's AI features actually say, and whether they use you.

What the tools do

They fall into four jobs:

• Check traffic and visibility. Which searches your pages appear for, and how often.
• Track AI answers. Whether your brand or pages are mentioned or cited for the questions you care about.
• Find questions. The questions people ask that your pages could answer.
• Audit your site. Whether crawlers can reach and read your pages.

What they cannot do

They cannot make an assistant recommend you. Nobody outside the AI companies controls that. Treat a tool as a thermometer, not a cure.

Google Search Console

Free, and the most important. It shows the searches your pages appear for, clicks, and which pages are indexed. Google counts visits from its AI features in the Performance report under the Web search type, together with normal results. Use the URL Inspection tool to check whether a page is indexed and request indexing for new ones.

Bing Webmaster Tools

Also free. It shows how Bing indexes your site, lets you submit your sitemap and URLs, and includes an AI Performance report, currently in public preview, that shows how often your site is cited in Microsoft's AI-generated answers, including Copilot.

The AI assistants themselves

The most direct test costs nothing. Ask ChatGPT, Perplexity, Gemini and Copilot the questions your customers ask, a few times each, in a private window. Note whether you are named, whether the facts are right, and which sources they cite. Our free AI visibility check does a version of this for you.

A tracking sheet

A spreadsheet with the date, the question, the tool and what it said is enough to see change over time. It is basic, and many businesses never need more.

Checking by hand gets slow once you have dozens of questions, several competitors or more than one location. Paid answer engine optimization tools automate that. Typical features include:

• Prompt tracking. You choose the questions, and the tool asks them again on a schedule.
• Visibility and share of voice. How often your brand appears compared with others.
• Citations and sources. Which pages and sites the AI tools cite in their answers.
• Sentiment. How the tools describe your brand.
• Reports and exports for clients or teams.

How to read the numbers

These tools sample a set of prompts, and AI answers change from run to run. A score of 40 does not mean you appear in 40 percent of everyone's searches. Use the numbers to spot direction and gaps, and test the important questions by hand too.

The table above reflects what Semrush, Ahrefs and Peec say about their products on their own websites at the time of writing. It is not a hands-on review, and we have no commercial relationship with any of them.

What each one says

• Semrush AI Visibility Toolkit reports an AI Visibility Score, prompt-level research, brand performance and sentiment, and includes a Site Audit check for whether AI crawlers can reach your site. It is one of Semrush's toolkits, so it suits teams already working there.
• Ahrefs Brand Radar shows how brands appear in AI answers, compares your AI share of voice with competitors and shows the pages AI tools cite most. Ahrefs describes AI platform data as an add-on on paid plans, with costs that rise with the number of platforms and prompts.
• Peec AI is a dedicated tool that measures visibility, position and sentiment across AI platforms, tracks cited sources and compares you with competitors. Its site lists no prices and points to a separate pricing page and a free trial.

Other tools exist

This is a fast-moving category with many newer products. If you try others, ask three questions: which AI platforms does it cover, how often does it run your prompts, and can you see the full answers it recorded, not just a score?

Stay free if

You have a small site, a handful of important questions and a monthly routine of checking them by hand. The free tools and a spreadsheet will tell you everything a paid tool would, only slower.

Consider a paid tool if

• You track more than a few dozen questions across several services or locations.
• You compete with several well-known brands and need to see where they are cited and you are not.
• You are an agency or in-house team that reports results to clients or managers.
• You already pay for Semrush or Ahrefs, and the AI add-on fits what you use.

Start small

Most paid tools offer trials or tiers. Begin with your twenty most valuable questions, run them for a month, and see whether the data changes what you do. If it does not, cancel.

It is tempting to buy a tool before fixing the content. Resist it. If your pages do not answer real questions directly, a dashboard will only show you that you are missing.

The steps that move results are the same ones in our guides: use customers' questions as headings, answer each in the first sentence, add specific details, keep your facts consistent, and make sure crawlers can read the page. Our guide on how to optimize your website for ChatGPT, Perplexity and AI search walks through them, and AEO vs SEO explains how the two fit together.

When to get help

If you have many pages, a technical site or no time to keep it up, an agency can do the fixing as well as the measuring. Our SEO and AI search service does exactly that, and we will tell you plainly if the free tools are enough for you.
