When people talk about "AI visibility" they often mean two different things. One is brand presence in conversational LLMs like ChatGPT, Claude or Grok, where users ask open-ended questions. The other is brand presence in AI-powered search engines like Perplexity, Google AI Mode or ChatGPT Search, where the user experience looks like search but the answer is AI-generated.
Both matter, but the tools, prompts and tactics differ. This guide focuses on the second category: AI search visibility tools, the trackers built specifically for AI search engines.
If you also need to track conversational LLMs (ChatGPT, Claude, Grok), see our broader comparison of the best AI visibility tools.
What counts as an AI search engine in 2026
Not every AI tool is an AI search engine. The category covers products where users formulate a search query (a question or keyword) and get an AI-generated answer, typically with sources cited. The major players:
- Google AI Overview: AI-generated summary at the top of standard Google SERPs. Now active on roughly 30% of US queries (May 2026).
- Google AI Mode: Standalone conversational search interface from Google, launched in 2024. Replaces traditional SERPs for users who opt in.
- Perplexity: Pure-play AI search engine with citation-first design. Strong growth in technical and academic audiences.
- ChatGPT Search: ChatGPT's built-in web search (tested in 2024 as SearchGPT). ChatGPT triggers it on its own when a question needs fresh information.
- Microsoft Copilot (in Bing): AI search integrated into Bing and Microsoft 365. Largest enterprise install base.
The behavioral pattern: users type a query, the engine surfaces an AI answer with 3 to 8 source citations. Your visibility on these platforms is about whether your domain ends up cited.
Conversational LLMs (the regular ChatGPT chat, Claude, Grok) work differently: users have multi-turn conversations and ask open-ended questions where citations are optional or absent. The tracking discipline is similar but the prompt design and measurement metrics shift.

The 5 AI search visibility tools worth knowing in depth
1. Mentionable
Mentionable covers AI search engines and conversational LLMs in one tool. It tracks Google AI Mode, Google AI Overview, Perplexity, ChatGPT, Claude, Gemini and Copilot every day, with a single dashboard plus a public MCP server (Pro and Agency plans).
What sets it apart in 2026 is that it does not stop at measurement. For any tracked prompt where the engines answer without mentioning your brand, Mentionable writes the page that closes the gap: a full markdown draft plus JSON-LD, built from the pages those engines cite instead, with the facts only you can supply flagged rather than invented. You review it, publish it on your own site, paste the URL back, and from the next scan on Mentionable reports whether the engines start citing it. Few tools in this list close that loop. It costs 150 credits per page and works on every plan, which makes it usable by brands with no writer on hand, not just by consultants.
The second strength is the public MCP server, on the Pro and Agency plans: your AI agent (Claude Desktop, Cursor, n8n) queries the tracking data directly, so briefs, audits and status checks run with real data instead of guesses.
Every plan, the free trial included, also comes with an AI assistant built into the dashboard: ask it which engine stopped citing you and it answers with your own numbers and a link to the page where you act, without using credits.
Pricing: €79/month (Growth: up to 115 prompts, all 7 AI engines, 1 project). €149/month (Pro: up to 231 prompts, all 7 AI engines, 3 projects). €299/month (Agency: 5,000 credits, unlimited projects, all 7 AI engines including Claude, white-label and one-shot GEO audit). MCP available on the Pro and Agency plans. 7-day free trial.
Best for: Brands, solo founders, consultants and in-house teams who want a single tool for AI search engines plus conversational LLMs, and who want the missing pages written rather than a report to interpret.
Trade-off: Generated pages are drafts, not publications. Mentionable never touches your site: you review the draft, fill in the flagged facts and publish it yourself.
2. ZipTie
ZipTie started with Google AI Overviews and now tracks 7 engines: Google AI Overview, Google AI Mode, ChatGPT, Perplexity, Copilot, Gemini and Bing AI Overview. Their angle is multi-country coverage (tracking AI answers in different regions and languages), usage-based pricing, and content optimization recommendations on top of tracking. If your business depends heavily on AI Overview placement (e-commerce, local SEO, multi-country brands), ZipTie's depth on the Google side is a real advantage.
Pricing: Usage-based, depending on prompt slots and scan frequency: Starter from $42.75/month, Professional from $659.59/month, Enterprise from $3,137.09/month. API and MCP as a $10/month add-on. 7-day free trial.
Best for: SEO teams whose primary AI search visibility concern is Google AI Overview and AI Mode, especially in multi-country setups.
Trade-off: No Claude tracking. If Claude matters to your audience, you need a second tool.
3. RankScale
RankScale has the widest engine coverage in this list: 17+ AI engines, including ChatGPT, Claude, Perplexity, Gemini, Copilot, Google AI Mode, Google AI Overview, Grok, DeepSeek and Mistral. The Pro plan costs $99/month for 1,200 credits (about 4,800 AI responses). Credit-based pricing means you pay for what you scan.
Pricing: $20/month (Essentials, entry plan), $99/month (Pro, 1,200 credits), $385/month (Growth, 5,500 credits), $780/month (Enterprise, 12,000 credits). 7-day free trial of Pro. MCP on Growth and Enterprise.
Best for: Teams that want the broadest engine coverage and are comfortable with credit-based pricing.
Trade-off: Credit math. If you scan often or run audits, credits run out faster than expected. Mentionable Growth at €79/month also runs on credits (1,500 a month, up to ~115 prompts), with any overage capped by a spending limit you set.
4. Otterly.ai
Otterly combines AI search visibility tracking with deep on-page GEO audits (25+ factors). Four engines are included (ChatGPT, Perplexity, Copilot, Google AI Overviews); Google AI Mode, Gemini and Claude are paid add-ons. Their analytics go deeper than most: sentiment analysis on AI search results, citation context, competitor positioning. The Lite plan at $29/month is the cheapest entry point for serious tracking, though it caps at 15 prompts on 1 workspace.
Pricing: $29/month (Lite, 15 prompts), $189/month (Standard, 100 prompts, unlimited workspaces, API and MCP), $489/month (Premium, 400 prompts).
Best for: Marketing teams that want detailed analytics and don't mind investing time to learn the platform.
Trade-off: Learning curve is real. If you just want a quick answer on AI search visibility, the feature density can feel overwhelming. Lite plan limits to one workspace.
5. Profound
Profound positions itself as competitive intelligence for AI search visibility. Rather than just tracking whether you appear, it analyzes the competitive landscape: who gets cited for which queries, how brand positioning shifts across AI search engines, market-level dynamics. It tracks up to 9 engines: ChatGPT, Perplexity, Google AI Mode, Gemini, Copilot, DeepSeek, Claude, Google AI Overviews and Exa Search. Profound raised a $180M Series D at a $1.8B valuation in September 2026.
Pricing: Free 7-day trial (50 prompts a day on ChatGPT, Gemini and Google AI Overviews), then Enterprise on quote. Profound also ships an MCP server.
Best for: Enterprise brands and agencies that need SOC 2 Type II compliance and category-level competitive intelligence.
Trade-off: No public price beyond the trial, so you go through sales. Overkill for individual practitioners.
AI search optimization tools: the other half of the loop
AI search visibility tools tell you where you stand. AI search optimization tools help you do something about it. The two categories work together. Most teams need both.
Surfer SEO
Surfer's content editor scores drafts on AI readability, structured data, and answer-format opportunities (FAQ, How-To). Their AI Tracker closes the loop by monitoring which of your pages get cited in AI answers. Pricing starts at $99/month (Standard).
Frase
Frase surfaces People Also Ask questions for your target keywords, generates answer-first drafts, and tracks featured snippet placement. The Solo plan at $14.99/month is the cheapest serious AI search optimization tool. Best for solo founders writing 1 to 5 pieces per month who want one tool for questions, briefs and snippet tracking.
Clearscope
Clearscope's NLP-driven approach surfaces semantic terms your draft needs to include. Less about questions, more about comprehensive coverage. Pricing starts at $129/month (Essentials), and Clearscope now also tracks brand mentions in ChatGPT, Gemini and Claude. Best for high-budget editorial teams.
MarketMuse
MarketMuse (owned by Siteimprove since 2024) scores drafts on topic depth, which correlates with AI Overview placement. The platform identifies content gaps and recommends entities to mention. Pricing is no longer listed publicly (free plan, then demo-based Optimize, Research and Strategy plans). Best for content engines producing 10+ pieces per month.
The pattern: AI search visibility tools measure result. AI search optimization tools shape what you publish. The most cost-effective stack pairs one of each, scaled to your monthly content volume.
How to measure AI search visibility (the metrics that matter)
Five metrics matter for AI search visibility, in order of importance:
- Citation rate: How often your domain appears as a source in AI answers, expressed as a percentage of total relevant queries. Target: 25%+ on your priority prompts within 6 months.
- Citation position: Where your link appears in the AI answer (first cited, last cited, mentioned in passing). First-cited sources receive 60%+ of clicks.
- Brand mention rate: How often your brand name appears in the AI answer text, independent of whether your domain is linked. Important when audiences read AI answers without clicking through.
- Sentiment: Whether the AI describes you positively, neutrally or negatively. Most tools score this on a -1 to +1 scale.
- Competitor share of voice: How your citation rate compares to your top 3 competitors on the same prompts.
A good AI search visibility tool tracks all 5 automatically. Most free or one-shot checkers handle 1 and 2 only. If you only see "citation count" without breakdown by competitor or sentiment, your tool is incomplete.
Building your AI search visibility stack
Three scenarios cover most teams.
Solopreneur on $50/month or less
- AI search visibility tracker: Otterly Lite at $29/month (15 prompts, 4 engines) or Mentionable Growth at €79/month (7 engines, MCP on the Pro and Agency plans)
- AI search optimization: Free schema generator + manual prompt research
- Total: $29 to $79/month
This stack tracks where you stand and gives you free optimization. Skip paid optimization tools until your tracking shows real movement.
Growing business on $150 to $300/month
- AI search visibility tracker: Mentionable Pro at €149/month (up to 231 prompts, all 7 engines) or Otterly Standard at $189/month (100 prompts)
- AI search optimization: Frase Pro at $44.99/month or Surfer Standard at $99/month
- Total: $200 to $280/month
This stack closes the feedback loop: track what AI says, shape what you publish, re-measure.
Agency or content engine on $500+/month
- AI search visibility tracker: Mentionable Agency at €299/month (7 engines, 5,000 credits, white-label, one-shot GEO audit) or Profound (Enterprise, on quote)
- AI search optimization: a higher Surfer plan (about $182 to $299/month) and Clearscope Essentials at $129/month
- Schema and llms.txt: Free Mentionable tools or Yoast/Rank Math integration
- Total: $600 to $1,000/month
This stack supports 10+ pieces of content per month, multiple client accounts, and the kind of consistent execution that compounds over 6 to 12 months.
What gets confused with AI search visibility
Three concepts come up often. Worth clearing up before you evaluate tools.
AI search visibility vs AI observability. AI observability tools (Datadog, Arize, LangSmith) monitor the internal performance of AI models for engineers (latency, errors, drift). AI search visibility is a marketing concern about whether AI engines cite your brand. Different category, different buyers.
AI search visibility vs GEO. GEO (Generative Engine Optimization) is the broader practice of getting your brand to show up in AI answers. AI search visibility tools are the tracking part of GEO. See our best GEO tools guide for the full GEO stack (tracking + content + schema + llms.txt).
AI search visibility vs AI SEO. AI SEO is the umbrella term used by traditional SEO platforms (Semrush, Ahrefs, Moz) for their AI features. The substance overlaps with AI search visibility but the framing is "SEO with AI features bolted on" rather than "GEO-native". See our best AI SEO tools comparison for the SEO-platform view.
The fastest way to clear the confusion: name the engines you want to track. If your list is Perplexity, Google AI Mode, AI Overview, ChatGPT Search and Copilot, you need AI search visibility tools. If your list also includes ChatGPT conversation, Claude and Grok, the broader AI visibility tools category covers both.
