The best AI SEO tools depend on the job: drafting content, optimising it against what ranks, researching topics, or tracking whether AI search mentions you. No single tool does all four well. Below are 11 tools sorted by the job they’re actually good at, with who each suits and where it falls short.

Disclosure: we make one tool on this list (the Keyword Rank Checker AI Visibility Checker). AI tools change quickly, so check each vendor’s site for current features and pricing; we’ve avoided quoting prices that may be out of date.

AI tools for drafting content

1. ChatGPT

The general-purpose assistant most SEOs already use for outlines, first drafts, meta descriptions, FAQ ideas and rewriting. It’s flexible and cheap for what it does. It doesn’t know your rankings or the current results page unless you give it that context, so pair it with real search data and edit for accuracy.

Best for: anyone who writes. Watch out for: confident mistakes and generic phrasing.

2. Copy.ai

An AI writing platform built around marketing workflows: blog drafts, product descriptions, social posts, with team collaboration and brand-voice settings. Useful when several people produce content and need consistency.

Best for: marketing teams. Watch out for: SEO depth is lighter than dedicated optimisation tools.

3. KoalaWriter

An AI article writer that uses the current search results for a keyword to shape a long-form, SEO-oriented draft. Popular with bloggers and affiliate sites that need a structured first draft quickly.

Best for: bloggers. Watch out for: drafts still need first-hand experience added before they’re worth publishing.

4. Contentpen.ai

An AI content platform that combines keyword research, drafting and on-page SEO checks in one place, aimed at marketers who don’t want to switch between tools.

Best for: small teams wanting one workspace. Watch out for: compare its research data with a dedicated tool before relying on it.

5. ContentShake AI

Semrush’s content writing app. It suggests topics, drafts articles and checks them for SEO using Semrush data, which makes its keyword suggestions more grounded than a general chatbot’s.

Best for: teams already using Semrush. Watch out for: it’s priced as a separate app.

AI tools for optimising content against what ranks

6. Surfer

Surfer analyses the pages ranking for your keyword and scores your draft on terms, structure and length, with integrations for Google Docs and WordPress. It’s one of the most widely used content optimisation tools.

Best for: content teams publishing regularly. Watch out for: chasing the score can make pages read like everyone else’s.

7. Clearscope

Clearscope grades drafts against top-ranking content and lists the related terms and questions to cover. Its reports are simple, which makes it easy for writers to use.

Best for: editorial teams who want clear briefs. Watch out for: it’s at the premium end for small sites.

AI tools for research and analysis

8. Semrush Copilot

Semrush’s AI assistant surfaces insights from your Semrush projects: ranking changes, site audit issues and competitor moves, so you see what needs attention without digging through reports.

Best for: existing Semrush users. Watch out for: it’s only as useful as the projects you’ve set up. Only use Semrush for rankings? See our Semrush alternative page.

9. Perplexity

An AI answer engine that cites its sources. For SEO it’s useful two ways: as a fast research assistant, and as a window into which sites AI answers trust for your topic.

Best for: topic research and checking AI citations by hand. Watch out for: answers vary between runs.

AI tools for tracking visibility in AI search

10. AthenaHQ

A platform for generative engine optimisation (GEO) that tracks how a brand appears across AI answer engines and suggests where to improve. Aimed at brands treating AI visibility as an ongoing programme.

Best for: brands that want continuous AI visibility monitoring. Watch out for: it’s a subscription product.

11. Keyword Rank Checker AI Visibility Checker

Our AI visibility checker sends your prompts to ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews and reports mentions, citations, share of voice and the sources each engine cites. It runs on your own DataForSEO account, so there’s no subscription, just a small cost per answer.

Best for: one-off audits and small budgets. Watch out for: no scheduled tracking; you re-run checks yourself. For more options, see our comparison of the best AI visibility tools.

How to choose an AI SEO tool

  • Start from the job, not the tool. If your problem is drafting speed, a writer helps. If your pages don’t rank, an optimiser or better research helps more.
  • Check where its data comes from. Tools built on live search data give better keyword and SERP advice than a chatbot working from memory.
  • Look at integrations. Google Docs, WordPress and Search Console connections save the most time.
  • Measure the result, not the score. Track rankings with a rank checker and AI mentions with the AI visibility checker after you publish.

Our take

AI tools make SEO faster, not easier. The posts that rank and get cited still contain something only you can add: your data, your experience, your opinion. Use AI to draft and optimise, then spend the time you saved making the piece worth citing. And measure the outcome in rankings and AI answers, not in content scores.

FAQ

What is an AI SEO tool?

Software that uses AI to help with SEO tasks: drafting content, optimising it against ranking pages, researching topics, auditing sites or tracking visibility in AI search.

Google says it rewards helpful content however it’s produced. It acts against content made mainly to rank at scale with little value, whether written by people or AI.

ChatGPT for drafting plus a free SERP checker to see what ranks is a low-cost start. Add an optimiser like Surfer or Clearscope when you publish regularly.
