Best AI Visibility Tools (2026): 10 Options Compared

What Are the Best AI Visibility Tools in 2026?

The best AI visibility tool depends on whether you need ongoing tracking or a one-time audit. In a Radar test on 14 September 2026, the AI search visibility tools that Perplexity and Gemini named most were Profound, Peec AI, Otterly.AI, Semrush and Ahrefs Brand Radar. Radar by Pixelmojo is the pay-per-audit option in this list: a free technical readiness audit, then $5 for a full 13-tool audit.

Disclosure: Pixelmojo makes Radar. That is why this page shows its method, dates every price, and lists Radar last.

AI visibility tools measure whether AI answer engines such as ChatGPT, Perplexity, Claude and Gemini mention and cite your brand when people ask questions in your category. As of 14 September 2026, most tools in this comparison are subscriptions that run a set of prompts every day or week. A few, including Radar, sell audits instead.

How Did We Choose and Check These 10 Tools?

We chose tools that AI engines and AI-cited roundups already associate with this category, then checked each one against its own website on the same day. The list is not a ranking.

The selection came from two sources, both captured in a Radar audit of pixelmojo.io on 14 September 2026:

1. Brands the engines named. Radar's Prompt SOV tool asked ChatGPT, Claude, Perplexity and Gemini five buyer questions about AI visibility audit platforms and recorded every brand in the answers.
2. Roundups the engines cited. Radar's Source Influence tool recorded the pages Perplexity cited for the same category, including third-party comparison articles.

For every tool, we fetched the vendor's pricing page and main product pages on 14 September 2026 and recorded plans, prices, engines, free options and technical checks as published. Where two pages from the same vendor disagreed, we say so. Plans change often, so check the vendor page before buying.

What we did not do: rank tools by quality or claim outcomes for any vendor. The "best for" notes below are our judgment, labeled as such.

Which Tools Do AI Engines Name for AI Visibility Audit Platforms?

When we asked four AI engines about AI visibility audit platforms, the most-mentioned brand held only 5.6 percent of weighted mentions. No tool dominates the answers, and half of the top ten were not AI search tools at all.

The split followed the engines. Perplexity and Gemini named AI search visibility tools: Profound, Peec AI, Otterly.ai, Semrush and Ahrefs Brand Radar. ChatGPT and Claude named tools that monitor machine learning models in production: Fiddler AI, Arthur AI, Weights & Biases, IBM Watson OpenScale and Google Cloud AI Platform. In total, the answers named 116 brands.

Our take: "AI visibility" is an ambiguous phrase. To some engines it means watching how a machine learning model behaves, not how a brand appears in AI answers. If you are researching this category with an AI assistant, say "AI search visibility" to get the right shortlist.

Limits of this data: it is one run of 5 prompts through each engine's API on one day. Answers vary between runs, so read it as a dated observation, not a market share figure.

How Do the 10 AI Visibility Tools Compare?

Most AI visibility tools are monthly subscriptions priced by prompt volume, and most now include some technical checks. The table shows each tool's lowest published plan and the engines that plan covers. Prices are as of 26 September 2026; engine lists are as of 14 September 2026.

Do AI Visibility Tools Check AI Crawler Access and llms.txt?

Yes, most of them do now. As of 14 September 2026, 7 of the 10 tools in this comparison describe AI crawler, robots.txt or llms.txt checks on their own pages.

Correction: an earlier version of this page, last updated in June 2026, said that no other tool audited AI crawler access. That is not accurate as of 14 September 2026, and this version replaces it.

Here is what the vendors say, in their own words:

• Otterly.AI offers a GEO Audit to "test 19 AI crawlers against your robots.txt and your live server."
• Peec AI documents that it "checks the domain's robots.txt against 40+ AI bots from 20+ vendors."
• Profound lists "AI crawlability diagnostics" and names pages blocked in robots.txt and missing or misconfigured llms.txt files among the issues it surfaces.
• Semrush Site Audit reports whether AI crawlers are blocked by robots.txt and raises an "Llms.txt not found" notice.
• AthenaHQ includes managing "AI crawler access with a smart robots.txt and llms.txt."
• Gauge runs "a nightly audit across 9 criteria," including crawlability gaps and structured data problems.

“Find and fix the technical issues preventing AI from accessing your pages.”

Profound, AI crawlability diagnostics page, fetched 14 September 2026

We did not find an AI crawler or llms.txt check on the Ahrefs Brand Radar, Ahrefs Site Audit or SE Ranking pages we reviewed. Ahrefs does offer Bot Analytics, which shows when AI crawlers visit, and lists it as free while in beta. Visiblie includes an entity and schema audit in its managed service.

Our take: the useful question is no longer "does this tool check crawlers?" It is how deep the check goes, whether it covers the specific bots you care about, and whether it tells you what to change. For background on why this layer matters, see AI monitoring vs AI technical readiness and what AI technical readiness means.

How Much Do AI Visibility Tools Cost in 2026?

As of 26 September 2026, the lowest paid subscription plans in this comparison run from $29 per month to $599 per month. The price mostly tracks how many prompts you monitor and how many engines you include.

Two things are easy to miss when you compare these prices. First, the engine list changes by plan: the Profound trial covers ChatGPT, Gemini and Google AI Overviews while Enterprise covers up to 9 engines, and Otterly.AI lists Claude, Google AI Mode and Gemini as extra add-ons. Second, the Semrush $99 per-domain price is billed annually, and some vendors discount annual plans, so confirm monthly versus annual billing before comparing totals.

Which AI Visibility Tools Track Claude and Google AI Overviews?

Most subscription trackers include Google AI Overviews, and fewer include Claude on their entry plans. Radar is the reverse: it includes Claude in every paid audit but does not track Google AI Overviews, AI Mode or Microsoft Copilot.

As of 14 September 2026, Claude appears on the Visiblie Starter plan and the AthenaHQ Starter plan. Otterly.AI offers it as an extra add-on. Profound and Peec AI list it on Enterprise, and Gauge lets you add it on any plan with your own Anthropic API key. SE Visible says Claude "will be added soon," and Ahrefs supports it through Custom Prompts.

If Google AI Overviews drives your category, choose a tracker that includes it. If your buyers use Claude, check which plan includes it before you compare prices.

Radar by Pixelmojo

Disclosure: Pixelmojo makes Radar. Radar is an audit, not a tracker. It runs 13 tools on one domain and returns a single report.

Pricing: a free technical readiness audit on any domain with no card. A full audit costs $5, or $12 for 3 and $40 for 10. Pro Retainer is $199/month for 40 audits.

What it covers: six technical readiness tools (AI crawler access across 17 user agents, robots.txt rules for 20 named bots, llms.txt validation, schema audit, AEO page audit and an AI Readiness score), plus seven AI answer tools, including citation, share of voice, source influence and hallucination checks across ChatGPT, Claude, Perplexity and Gemini. You can watch a domain for a weekly re-scan and get an email when the score moves.

Limitations: Radar does not track Google AI Overviews, AI Mode or Microsoft Copilot, and it does not run prompts daily.

Best for: Finding out why AI engines are not citing you before you pay for a monthly tracker. See a sample report and how Radar scores.

Should You Choose a Tracking Subscription or a Pay-Per-Audit Tool?

Choose a tracking subscription if you need to report the same prompts every month. Choose a pay-per-audit tool if you need to diagnose a problem, audit a client, or check a competitor once.

Our take: the two models complement each other. An audit tells you what to fix. A tracker tells you whether the fix worked across the prompts you care about.

How Do You Choose an AI Search Visibility Audit Tool?

Start with the engines your buyers use, then decide between tracking and auditing, then compare prompt volume and price. Four steps keep the decision short.

1. Pick the engines. List the AI tools your buyers actually use. If that includes Google AI Overviews, Radar is not enough on its own. If it includes Claude, check which plan includes it.
2. Decide between tracking and auditing. Ongoing reporting needs a subscription. A one-off diagnosis or client audit fits a pay-per-audit tool.
3. Check technical access first. Run a free crawler and llms.txt check before you pay for tracking, so you are not measuring a site AI crawlers cannot reach.
4. Size the plan. Count the prompts you need, the seats, and whether the published price assumes annual billing.

For a guide to the free options, see our free AI visibility tools guide.

What Can You Check for Free?

You can check a lot for free, but no free option covers ongoing multi-engine tracking. As of 14 September 2026, these are the free options in this comparison:

1. AthenaHQ Essential: a free plan with 300 credits across ChatGPT, Perplexity, AI Overviews, Gemini and Copilot.
2. Radar free technical readiness audit: crawler access, robots.txt, llms.txt, schema, AEO page and AI Readiness score on any domain, with no card.
3. Ahrefs Bot Analytics: shows AI crawler visits, listed as free while in beta.
4. Free trials: Otterly.AI, Peec AI, Gauge (1 week), SE Visible (10 days) and SE Ranking (14 days).
5. Manual prompts: ask ChatGPT, Claude, Perplexity and Gemini the questions your buyers ask. It is free but slow, and answers vary between runs.

What Should You Do Next?

Check whether AI crawlers can reach your site, then choose the tracker that covers your buyers' engines.

1. Run a free technical readiness check. It takes about a minute and shows crawler access, robots.txt, llms.txt and schema issues.
2. Fix what blocks AI crawlers. Do it first, so tracking measures your content rather than your access settings.
3. Pick a tracker by engine coverage. Use the comparison table above and confirm the price on the vendor page.
