How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- Most AI visibility tools can tell you whether ChatGPT or Perplexity mentions your brand. Fewer tell you which topics and prompts you are missing, so check how each tool surfaces gaps before you buy.
- Scrunch is the only tool here where we could confirm a full price from the vendor's own page: $250 per month billed annually for Starter, or $300 month-to-month, with a 7-day free trial.
- Peec AI and Otterly.AI suit small teams that want tracking and competitor comparison without an enterprise contract. Profound and Scrunch lean toward larger teams that want help acting on the gaps.
- Semrush and Ahrefs make sense if you already pay for one of them, because the AI data sits next to your keyword and backlink research.
- Prompt limits, AI engine coverage and add-on fees change the real cost more than the headline price. Several vendors change plans often, so confirm numbers on the pricing page.

The best AI brand visibility software for content gaps
A content gap in AI search is a question your buyers ask an AI assistant where your brand is absent and a competitor is cited. The tools below monitor prompts across assistants such as ChatGPT, Perplexity, Gemini and Google AI Overviews, then show where you are missing. They differ in how far they go past the report.

Scrunch is the easiest tool in this list to price. Its own page lists Starter at $250 per month on annual billing ($300 monthly), Growth at $417 annually ($500 monthly), and custom pricing for Enterprise. Starter includes 350 custom prompts, 1,000 industry prompts and 3 personas.
What stands out for gap work is the pairing of an Insights view, which the vendor says is meant to surface content gaps, with page audits that check how well a specific page is set up for AI agents. You can follow a gap from "we are missing on this prompt" to "this page needs these changes" inside one product. Coverage includes ChatGPT, Claude, Gemini, Perplexity, Google AI Mode and AI Overviews, and Meta.
The catch is scale. Starter allows five audits, so a site with hundreds of pages will hit the ceiling quickly. Extra seats cost $25 per month each, and support is email only below Enterprise. The 7-day trial on Starter needs no credit card, which is enough time to load your core prompts and judge the insights.
What we like- Insights feature built to spot opportunities and content gaps
- Page audits on every plan
- Unlimited key topic monitoring
Watch out for- Seats are capped (3 on Starter, 5 on Growth)
- Only 5 page audits on Starter
#2Peec AI

Peec AI is a Berlin-based tool aimed at marketing teams that want to see brand performance across AI assistants without a long sales process. Its own materials describe a Starter plan in the roughly $85 to $103 per month range, with unlimited team seats, a choice of three AI engines, and data export. Treat those as approximate and confirm on the pricing page, since the figure depends on billing and currency.
The strength is clarity. You set up prompts, choose competitors, and see visibility, position and the sources the assistants cite. For gap work, the cited-source view is the useful part: it shows which domains the assistants trust on topics where you are missing, so you know where your content needs to appear or be matched.
The honest weakness is that Peec says it does not generate content by design. It shows the gap and hands the writing back to your team. If you want drafts or briefs from the same product, look at Profound or Goodie. If you already have writers and an editor, that restraint may be a plus.
What we like- Low entry price compared with enterprise tools
- Unlimited team seats on the entry tier per the vendor
- Clear competitor benchmarking
Watch out for- Does not write or publish content
- Fewer workflow tools than larger platforms

Profound is one of the best-known names in AI visibility and is built mainly for brands with big content operations. Its pitch goes beyond monitoring into recommended actions and content creation on higher tiers. For a team with a content calendar and several markets, that makes the step from gap to brief shorter.
Pricing is the sticking point. Third-party reviews report that the low-priced self-serve plans were withdrawn in September 2026, and that enterprise tiers are custom. We could not confirm current plans from the vendor's page, so ask for a quote and ask what prompts, regions and engines are included.
A small business with a handful of products will probably pay for capacity it does not use. Mid-size and larger teams, especially in regulated or multi-country settings, are the better match. Ask for a trial on your own prompts before you sign anything long.
What we like- Broad engine coverage aimed at enterprise needs
- Content recommendations on higher tiers
- Strong fit for multi-region brands
Watch out for- Pricing has shifted and is often quote-based
- Likely more than a small team needs
#4Otterly.AI

Otterly.AI is a good starting point if you want to watch 15 to 100 prompts and see which brands appear. Public reviews describe three tiers (Lite, Standard and Premium) priced from the high twenties per month up to a few hundred, with extra charges for some AI models. Check the live page, because add-ons change the total.
For content gaps, you will use it mostly as a monitor. Track the questions your buyers ask, note where competitors are cited and you are not, then take that list to your writers. It will not plan the content for you.
The risk is that a cheap plan looks adequate until you add the engines you care about. Price your real prompt list and engine mix before comparing it to anything else here.
What we like- Low entry pricing reported by reviewers
- Simple prompt tracking setup
- Useful for spot checks on a few key topics
Watch out for- Prompt counts are small on lower plans
- Extra AI engines can cost more

If your team already lives in Semrush, the AI Visibility Toolkit is the low-friction option. You can compare where you rank in classic search with where you appear in AI answers, which helps you spot topics where you rank well on Google but are absent from AI summaries. Those are often the cheapest gaps to close, because you already have a page.
Reviewers describe an entry add-on around $99 per month for 25 prompts, and a Semrush One bundle that combines the SEO toolkit with AI visibility. We could not verify these from the vendor's page, so see the website for current plans.
The weakness is depth of AI-specific work. Prompt allowances are small compared with the tracking-first tools, and the total bill includes your base Semrush subscription. It rewards teams that will use the whole platform.
What we like- AI data sits beside keyword and site audit tools
- Familiar interface
- Useful for linking AI gaps to organic search gaps
Watch out for- Prompt allowances are modest at entry level
- Costs add up on top of a Semrush plan

Brand Radar comes from Ahrefs and works differently from prompt-list trackers. It draws on a large index of AI answers and brand mentions, so you can explore how often brands in your market appear without entering every prompt by hand. For gap hunting, that wide view is the point: you find topics you had not thought to track.
Ahrefs lists a free AI visibility checker on its site, which is a quick way to get a first look. The paid Brand Radar is reported by reviewers as an add-on to an Ahrefs subscription, priced per AI platform or as a bundle. Prices vary across reviews, so confirm on the vendor page.
If you are not an Ahrefs customer, the total cost can be hard to justify for a small team. If you are, it is probably the most natural place to start.
What we like- Large index of AI prompts and mentions
- Fits alongside Ahrefs keyword and backlink data
- Good for market-level research
Watch out for- Reviewers report it is priced as an add-on to an Ahrefs plan
- Per-platform costs add up

Rankscale is a Vienna-built platform that describes itself as an AI visibility platform for agencies and enterprise teams. It says it monitors 17 or more AI engines, including ChatGPT, Perplexity, Gemini and Google AI Overviews, and its homepage invites visitors to start a free trial. The vendor also adds new engines quickly; the homepage was announcing support for Meta Muse Spark when we checked.
It fits agencies that need a separate dashboard per client and want to report across many brands. For a content gap review, the wide engine coverage helps if your buyers use less common assistants.
Pricing is the part to verify. Third-party listings mention a low-priced entry tier, but the vendor's own pricing page did not load for us, so see the website. A single-brand business will likely pay for agency features it does not use.
What we like- Built for agencies and enterprise teams
- Covers 17 or more AI engines per the vendor
- Offers a free trial
Watch out for- Positioning favors agencies, so solo owners may find it more than they need
- Pricing needs checking on the live page

Goodie describes itself as an AI search visibility and answer engine optimization platform. It tracks brand presence, runs competitor analysis, and offers content optimization recommendations from a central hub. That puts it closer to Profound than to pure monitors like Otterly.AI.
For content gaps, the draw is having the finding and the recommended fix in one workflow. A small marketing team without a dedicated analyst may get more from that than from a dashboard of charts.
The caution is cost clarity. Reviewers say some engines are gated by tier and cost extra on lower plans, and we could not confirm current prices from the vendor, so request a written quote that lists engines and prompts.
What we like- Combines monitoring with content optimization recommendations
- Competitor analysis
- Designed around answer engine optimization
Watch out for- Engine coverage can vary by tier per reviewers
- Pricing is not clear from public sources
How we chose
We built this list from vendor websites and pricing pages, product documentation, and public reviews on sites such as G2 and Capterra, plus discussion on Reddit and independent review blogs. We did not run these products ourselves, and nothing here is a hands-on test result. We compared what each tool says it tracks, how it surfaces missing topics, which AI engines it covers, and how it fits different company sizes.
Where a vendor's pricing page was available to us, we used it. Where it was not, or where third-party numbers disagreed, we wrote "See website" rather than guess. This category changes fast, with plans and limits revised often, so check the live page before you budget.
How to pick a tool for content gap work
Start with the gap you need to find
There are two kinds of gap. The first is a prompt gap: a specific question where you are not mentioned. The second is a source gap: sites the assistants cite that never mention you. Prompt-list trackers like Peec AI, Otterly.AI and Scrunch are strong on the first. Index-style tools like Ahrefs Brand Radar are better for discovering topics you had not thought of.
Decide who writes the fix
If you have writers and an editor, a tool that only reports gaps is enough, and it will cost less. If you have no content team, favor tools that propose briefs or page changes, such as Profound, Goodie or Scrunch with its page audits. Be sceptical of any recommendation you cannot trace back to a prompt and a cited source.
Count prompts and engines before you compare prices
A plan with 25 prompts on two engines is not comparable to one with 350 prompts on seven. List 30 to 50 questions your buyers ask, mark the engines they use, and ask each vendor to price that exact setup. Check add-on charges for extra engines, regions and seats.
Check contracts and exports
Ask whether billing is monthly or annual, what happens when you hit a prompt limit, and whether you can export your data. Scrunch publishes a 17 percent discount for annual billing and says it will contact you rather than block you at limits. Get similar commitments in writing from others.
Run a 30-day test on your own prompts
AI answers vary from run to run, so a single snapshot proves little. Load the same prompt set into two tools if possible and compare the gaps they report. The gaps both agree on are the ones to write about first.
Frequently asked questions
What is a content gap in AI search?
It is a question or topic where AI assistants name competitors or cite other sites but do not mention your brand. Closing it usually means publishing or improving a page that answers the question clearly, and earning mentions on sources the assistants already trust.
Do I need a dedicated tool, or can I check ChatGPT by hand?
Manual checks work for a dozen prompts. They fall apart when answers change daily and you need to compare competitors across several engines. A tool gives you repeatable tracking and a history, which is what you need to show whether your fixes worked.
Which tool is best for a small business?
Peec AI and Otterly.AI are the usual starting points for small teams because of their lower entry pricing. If you already pay for Semrush or Ahrefs, check their AI add-ons first. Confirm each price on the vendor page, since plans change.
How much should I expect to spend?
Entry plans from the tools here run from under $100 per month to a few hundred, and enterprise tiers are quoted individually. Scrunch's published Starter plan is $250 per month on annual billing. The real total depends on prompts, engines, seats and add-ons.
How long until content changes show up in AI answers?
It varies by assistant and topic, and no vendor can promise a timeline. Plan to track the same prompts for several weeks after publishing a fix, and look at trends rather than single results.
