| Quick answer |
|---|
| The best answer optimization tools for improving AI visibility are Semrush AI Visibility Toolkit at $99 a month, which pairs prompt tracking with an AI Search Site Audit, and Scrunch AI for diagnosing missing or misrepresented content. Surfer SEO from $49 and Frase from $39 do the page work. |
| How we compare |
|---|
| Tools are ranked on whether they produce an instruction you can act on rather than only a chart, on published pricing, and on what each plan includes at its stated unit. Prices were checked on vendor pricing pages in September 2026; several vendors quote rather than publish. Every price was re-checked against the vendor’s own pricing page in September 2026, and figures available only from third-party trackers are marked as reported. No vendor paid for placement. We ran no head-to-head lab test — every figure here is public and re-checkable. |
Table of Contents
Measuring is not optimising
Most products marketed as answer optimisation tools are measurement tools with an optimisation label. Separate three jobs before you spend anything.
- Measure. Are you named in the answer, how often, and with a link. Otterly, Peec and most of the category.
- Diagnose. Which pages and which gaps explain the absence. Semrush’s AI Search Site Audit, Scrunch’s missing and misrepresented content reports.
- Change. Rewrite the page so it can be extracted. Surfer SEO, Frase, and a person who can write.
Only the third one moves anything, and it is the one no subscription performs for you. The strategy behind it sits in our guide to generative engine optimisation, and ranking inside ChatGPT specifically narrows it to the single engine most teams start with. A monitoring tool bought without page capacity produces a very precise record of your absence.

What actually changes an AI answer
The page work is unglamorous and consistent across engines.
- Answer in the first 60 words. Put a direct, specific answer above the preamble. This is the block that gets extracted.
- Make each section self-contained. A chunk that depends on the paragraph before it cannot be quoted on its own.
- Be specific enough to quote. Prices, dates, named limits and version numbers survive summarisation. Adjectives do not.
- Render without JavaScript. If the answer only exists after hydration, assume it is not read.
- Match your schema to the visible text exactly. Hidden or mismatched markup is a policy problem, not a shortcut: Google’s structured data general guidelines require marked-up content to be visible to the user.
None of that requires a subscription. It requires knowing which pages to fix, which is the one thing the diagnostic tools genuinely provide.
What one unit of work actually costs
Every tool here bills in a different unit — prompts, articles, credits, domains — which is why the sticker prices look interchangeable when they are not. Dividing each published price by the quantity that vendor publishes with it gives a figure none of them prints:
| Plan | Published price | Unit the vendor includes | Cost per unit (our calculation) |
|---|---|---|---|
| Surfer SEO Discovery, billed yearly | $49/mo | 120 documents a year | $49 × 12 ÷ 120 = $4.90 per document |
| Surfer SEO Standard, billed yearly | $99/mo | 360 documents a year | $99 × 12 ÷ 360 = $3.30 per document |
| Semrush AI Visibility Toolkit | $99/mo | 25 tracked prompts, 1 domain | $99 ÷ 25 = $3.96 per prompt |
| Semrush + the 50-prompt top-up | $99 + $60 = $159/mo | 75 tracked prompts | $159 ÷ 75 = $2.12 per prompt |
| AthenaHQ Starter | $295/mo | 3,600 credits, 3 seats | $295 ÷ 3,600 = $0.082 per credit; $295 ÷ 3 = $98.33 per seat |
| Profound Starter / Growth | $99 / $399/mo | 50 / 100 tracked prompts | $1.98 / $3.99 per prompt |
| Frase Starter, billed yearly | $39/mo | 10 articles | $39 ÷ 10 = $3.90 per article |
Two things fall out of that column. First, the top-up is cheaper than the base plan: Semrush’s extra 50 prompts cost $60 ÷ 50 = $1.20 each, against $3.96 for the 25 bundled into the subscription, so the marginal prompt is roughly a third of the price of the first one. Second, Surfer counts documents per year, so a Discovery document costs $4.90 — more than a bundled Semrush prompt, and the unit to watch if you rewrite in volume.
The $100-a-month decision therefore has an arithmetic answer, not a taste one: $99 a month on Surfer Standard buys 360 documents a year, 30 a month at $3.30 each, while $99 on Semrush buys 25 tracked prompts at $3.96 each plus one site audit. For the measurement half of the market on its own, our pillar comparison of AI search monitoring platforms covers the trackers this list deliberately downgrades.
Every unit in the table is the one the vendor prints on its own pricing page, so you can re-run the division when prices move.
The tools in detail
Semrush AI Visibility Toolkit
The Semrush $99 a month add-on is one of the few that ships a diagnostic rather than only a dashboard: an AI Search Site Audit runs alongside Prompt Research, Competitor Research and Brand Performance. Covers one domain and 25 prompts, with 50 more at $60, each extra domain at $99 and extra users at $45.
Scrunch AI
Scrunch AI is built to identify where your content is missing, misrepresented or cited less often than a competitor, which is diagnosis rather than measurement. Acquired by Sitecore for about $225 million in June 2026 and now sold as part of a digital experience suite, and it lists Starter at $300 a month, or $250 billed yearly, for 350 prompts and three seats, with Growth at $500 ($417 yearly).
Profound
Starter is $99 a month covering ChatGPT only and Growth is $399 adding Perplexity and Google AI Overviews, with Enterprise custom up to nine engines. Goes further than most trackers into recommendations, but the useful engine coverage sits above the entry tier.
AthenaHQ
Starter is $295 a month with 3,600 credits, eight platforms, three seats and one country. Content creation workflows with deep research sit on the Enterprise tier alongside SAML SSO and API access, so the optimisation half of the product is the part you have to negotiate for.
Surfer SEO
Surfer SEO does page-level content optimisation rather than AI tracking. Its pricing page lists Discovery at $49 a month billed yearly, Standard at $99 and Pro at $182, with document allowances counted per year, plus a separate AI Search Analytics product at $82 for 50 daily-tracked prompts. Useful because extractable structure and on-page coverage are what AI answers actually quote.
Frase
Frase is the cheapest way to work on answer structure at scale, and prices in articles you can count: Starter is $39 a month billed yearly for 10 articles, Professional $103 for 40 and Scale $239 for 100.
How to spend the budget
If you have $100 a month, spend it on Semrush AI Visibility Toolkit or on Surfer SEO — not half on each. The audit tells you which twenty pages matter; the editor helps you fix them. If you already know which pages are failing, skip straight to the editor, and Frase does the same job for a fraction of the price.
If you have $400 a month and multiple brands, Profound Growth or AthenaHQ Starter become reasonable, but check what sits behind the Enterprise wall first: at AthenaHQ the content workflows do, and content workflows are the reason you were buying.
Our guide to answer engine optimisation covers the discipline itself, answer engine optimization tools covers the wider tooling market, and how to rank in Google AI Overviews covers the page mechanics in detail. If the rewriting lands with a marketing team rather than an SEO, our roundup of AI tools built for marketers covers the production side.
Frequently Asked Questions
What are the best answer optimization tools for improving AI visibility?
Semrush AI Visibility Toolkit at $99 a month is the best all-round pick because it pairs prompt tracking with an AI Search Site Audit, and Scrunch is the strongest at diagnosing where your content is missing or misrepresented. Surfer SEO from $49 and Frase from $39 handle the page-level work that actually changes the answer.
Which answer engine optimization tools work best for AI visibility?
The ones that tell you what to change, not just what happened. Semrush ships an AI Search Site Audit, Scrunch flags content that is missing or misrepresented, and Profound and AthenaHQ add recommendation layers on their higher tiers. Pure trackers such as Otterly and Peec are cheaper and excellent at measurement, but they will not produce a single page edit.
What’s the best AI optimization tool for visibility?
It depends which half of the problem you have. If you do not know where you stand, buy measurement — Otterly from $29 or Peec from EUR 85. If you already know you are absent from answers your competitors appear in, buy diagnosis and page tooling instead: Semrush at $99 for the site audit, plus Surfer SEO from $49 or Frase from $39 for the editing itself. Most teams buy measurement twice and page tooling never.
Which pages should you optimise first for AI answers?
The ones on prompts where competitors are named and you are not. Semrush’s AI Search Site Audit and Scrunch’s missing-content reports produce that list. Without either, take your twenty most commercial pages, check each against the prompt it should answer, and rewrite any whose answer is not in the first 60 words.
How long after a rewrite does an AI answer change?
Allow two to four weeks. After you rewrite a page the engine has to recrawl it and your tool has to refresh — weekly on entry plans, daily on higher tiers, with the cadence rarely published — so judging a change sooner mostly measures noise. Ask for the refresh figure in writing during the trial.
Conclusion
Buy diagnosis and page tooling, not another dashboard. Semrush AI Visibility Toolkit at $99 is the most complete single subscription because the AI Search Site Audit turns a visibility gap into a page list, and Scrunch does the same job at enterprise scale inside Sitecore.
Then put the second $100 into content optimization rather than a second tracker. Surfer SEO from $49 or Frase from $39 will not tell you where you rank in AI answers — they will help you write the paragraph that gets quoted, which is the part every tool in this category measures and none of them does.
