16 AI tools for SEO across content, suites, technical fixes and AI visibility, with every price read from the vendor's own pricing page and the date attached.

Updated 26 September 2026Prices read on 26 September 2026

We built one of the tools in this table, CoreCited, so weigh our opinion on which is best accordingly. What you can check is the data: every price below was read from the vendor's own pricing page on 26 September 2026, every tool has real strengths listed as well as limits, and where a vendor does not publish a price, we say so instead of guessing.

Key takeaways

1"AI SEO tool" covers four different jobs: writing content, running an SEO suite, deploying technical fixes, and tracking AI visibility. Pick the job first.

2Entry prices range from $20 to $299 a month, and 2 vendors publish no price at all.

3The headline price often buys a narrow slice: few prompts, one engine or one seat. Compare what the entry plan includes.

43 tools have a free plan and 12 offer a free trial, so you can test most of them before paying.

Price tells you little on its own. A $29 plan with 15 prompts on four engines and a $129 plan with unlimited users are different products. Open each row in the table above for what the entry plan actually buys.

How to choose an AI SEO tool

“AI SEO” means two things: using AI to do SEO work, and doing SEO so AI engines cite you. Our AI SEO guide explains both. Whether a vendor calls itself AI SEO software, an AI SEO platform or one of the new SEO AI tools, start from the job you need done:

Look at the content optimisation tools: Surfer, Frase, Clearscope, MarketMuse, Scalenut, Jasper, Writesonic. They grade drafts against what already ranks and suggest topics and terms to cover. Several now add AI visibility tracking.

Try two on the same article during their trials; the one whose suggestions you would actually follow is the right one.

Best AI tools for SEO content

Content tools are the oldest AI SEO category. They compare your draft with the pages that already rank and tell you what is missing. Surfer has the most mature editor and bundles AI prompt tracking from its Standard plan. Frase is the cheapest way to get research, writing, publishing and AI visibility together, and includes tracking on every plan. Clearscope is the simplest to adopt across a team, with unlimited users. MarketMuse is for topic-level strategy, and has a free plan. Jasper and Writesonic lean towards generation, and Scalenut combines writing, clustering and basic tracking at a low price.

Best SEO suites with AI features

If you already pay for a suite, check its AI features before buying anything else. Semrush adds AI visibility reports to its SEO plan and sells daily prompt tracking in its Semrush One bundles. Ahrefs includes a handful of tracked AI prompts from its Lite plan up and sells market-wide Brand Radar AI data as an add-on. SE Ranking is the lowest-cost full suite here, with a 200-prompt AI Search add-on.

Best AI visibility tools

These track the other half of AI SEO: whether AI engines name you. Rankscale and Otterly.AI are the cheapest ways in, Rank Prompt has a real free plan, and Profound is the enterprise option with no published price. CoreCited, ours, is built around one question the others do not answer: whether you hold a durable place in the answer or rotate through it (Core vs Carousel), with honest error bars on share of voice.

Free AI SEO tools

You can do a surprising amount without paying. MarketMuse, CoreCited, Rank Prompt have free plans, and most other tools offer a trial. These free tools of ours need no account at all:

AI SEO Checker: 31 checks on any page, including answer-first structure and crawlability.
AI Visibility Checker: whether AI engines name your brand, with the real answers.
Schema Markup Generator: valid JSON-LD for FAQ, Article, Product and more.
Robots.txt Generator: allow or block each AI crawler, and test any URL.
llms.txt Generator: a file built from your real sitemap.

What no AI SEO tool can tell you

Be sceptical of these numbers, whoever shows them

Clicks from Google's AI Overviews and AI Mode. Search Console counts them as ordinary organic clicks and no API separates them, so any tool showing that traffic has modelled it. A “rank” in an AI answer. AI answers change their sources weekly; a single position is noise. Exact prompt volumes. Nobody can measure how often people ask AI a question without a licensed consumer panel; figures derived from keyword data are estimates.

Questions people ask

What is the best AI SEO tool?

There is no single best one, because AI SEO tools do different jobs. For writing and optimising content, look at Surfer, Frase or Clearscope. For an all-in-one SEO suite with AI features, Semrush, Ahrefs or SE Ranking. For deploying technical fixes automatically, Alli AI. For tracking whether AI engines like ChatGPT and Gemini mention your brand, a dedicated AI visibility tracker. Choose by the job, then compare price and limits within that group.

Are there free AI SEO tools?

Yes. In our table, MarketMuse, CoreCited, Rank Prompt have a free plan, and most others offer a free trial. There are also free single-purpose tools that need no account, such as our AI SEO Checker, AI Visibility Checker, Schema Markup Generator, llms.txt Generator and Robots.txt Generator.

What do AI SEO tools actually do?

Two different things. Some use AI to help you do SEO work faster: keyword clustering, briefs, drafts, optimisation scores, meta tags and technical fixes. Others track SEO for AI: whether ChatGPT, Gemini, Perplexity and Google's AI features mention and cite your brand. Several tools now do a little of both.

Is AI-generated content bad for SEO?

Not in itself. Google's guidance is that it rewards helpful content however it is produced, and that using automation primarily to manipulate rankings breaks its spam policies. AI writing tools are useful for drafts; the risk is publishing generic text with no original insight, which is where editing by someone who knows the subject matters.

Which AI SEO tools track ChatGPT and AI Overviews?

Most tools in the AI visibility category track both, and several content tools now include some tracking: Surfer's AI Tracker, Frase's AI visibility, Clearscope's query tracking on ChatGPT and Gemini, and Writesonic's daily prompt tracking. Engine coverage varies by plan, so check which engines the plan you would buy includes, not the vendor's maximum.

How much do AI SEO tools cost?

Entry prices in this table run from $20 to $299 a month for the cheapest paid plan, and 2 vendors do not publish a price at all. The headline price often buys a narrow slice: few prompts, one engine, one seat. Read what the entry plan includes before comparing numbers.

Is Semrush or Ahrefs better for AI SEO?

Both now include AI visibility features on top of their SEO data. Semrush sells an AI Visibility Toolkit for $99 a month and bundles AI tracking into its Semrush One plans; Ahrefs includes a few tracked AI prompts from its Lite plan up and sells its market-wide Brand Radar AI data as an add-on from $199 a month. If you already use one of them, start there.

Do I need an AI SEO tool at all?

Not to start. You can ask ChatGPT and Perplexity the questions your buyers ask and write down who is named, and you can run free checks on your pages. A paid tool earns its place when you need to do that repeatedly, across many questions and engines, and keep the history.
