AI Search Changed the Game. These Tools Help You Track It.
AI search engines now influence how millions of people discover businesses, products, and information. When someone asks ChatGPT, Perplexity, or Claude for a recommendation, the answer comes with citations -- links to the sources the AI trusted enough to reference.
The question every website owner should be asking: is my site one of those citations?
Traditional SEO tools cannot answer that question. They track Google rankings, not AI citations. A new category of tools has emerged specifically to monitor whether AI search engines cite your website -- and who they cite instead.
We tested and compared the best AI citation tracking tools available in 2026. Full disclosure: llmstxt.studio is one of them. We built it, so we obviously think it is good. But we are going to be honest about where each tool excels and where it falls short, including our own.
Quick Comparison: AI Citation Tools at a Glance
Here is the summary before we go deep on each tool.
| Tool | Starting Price | Free Tier | AI Engines Tracked | Best For |
|---|---|---|---|---|
| llmstxt.studio | Free / $19/mo | Yes | 1 | Small businesses, solopreneurs |
| Otterly | $29/mo | No | Multiple | Budget-conscious teams |
| AIclicks | $49/mo | No | Multiple | Mid-market, click attribution |
| Promptwatch | $99/mo | No | Multiple | Agencies, enterprise |
| Peec AI | $99/mo | No | Multiple | Enterprise, deep analytics |
What to Look for in an AI Citation Tracking Tool
Before we break down each tool, here is what actually matters when choosing one.
Query generation
Does the tool generate relevant queries automatically, or do you have to write every prompt yourself? Manual query writing is a hidden time cost that most comparison articles ignore. See how Smart Query Generation works in llmstxt.studio.
Competitor visibility
Knowing you are not cited is useful. Knowing who is cited instead is actionable. The best tools show competitor domains alongside your own results.
Trend tracking
A single snapshot tells you where you stand today. Trend data tells you whether your efforts are working. Look for tools that track citation rates over time.
Multi-engine coverage
ChatGPT, Perplexity, Claude, and Gemini each cite differently. Some tools track multiple engines; others focus on one. More coverage costs more.
Generation + measurement
Most tools only measure. A few also help you improve your AI visibility through content generation or optimization features. This closes the loop between diagnosis and action.
1. llmstxt.studio
Pricing: Free ($0), Pro ($19/mo), Premium ($49/mo)
Full disclosure -- this is our tool. We are listing it first because it is our blog, but we will be straightforward about what it does well and where it has limitations.
llmstxt.studio is the only tool on this list that connects AI content generation to citation measurement. It generates a spec-compliant llms.txt file for your website, monitors your site for changes, and then runs AI citation checks to see whether your site is being recommended.
The citation check works by automatically generating queries based on your actual llms.txt content -- brand discovery queries, topic authority queries, and competitive landscape queries. You do not have to write prompts manually. It queries an AI search engine, checks whether your domain appears in the citations, and shows you which competitors appeared instead.
Strengths
- -- Free tier available (3 lifetime citation checks)
- -- Cheapest paid plans in the category
- -- Auto-generated queries from your actual content
- -- Only tool that generates llms.txt + measures citations
- -- Competitor domain visibility in results
- -- Sitemap monitoring for content freshness
- -- Trend tracking with baseline comparisons
Limitations
- -- Queries one AI search engine, not multiple
- -- Smaller query volume than enterprise tools
- -- No click-through attribution
- -- No white-label or agency reporting
- -- Newer tool with a smaller user base
Bottom line: Best value for small businesses and solopreneurs who want the full lifecycle -- generate, monitor, measure -- without spending $100+/month. If you need multi-engine tracking or agency features, look further down this list.
2. Promptwatch
Pricing: Essential ($99/mo), Professional ($249/mo), Business ($579/mo)
Promptwatch is one of the more established players in AI visibility monitoring. It positions itself as an enterprise-grade solution for tracking how brands appear across multiple AI search engines.
The platform tracks mentions across ChatGPT, Perplexity, Gemini, and other AI assistants. It offers detailed reporting on brand sentiment, competitor share of voice, and citation frequency. The dashboard is polished and the analytics are deep.
Strengths
- -- Multi-engine tracking (ChatGPT, Perplexity, Gemini)
- -- Deep analytics and reporting
- -- Brand sentiment analysis
- -- Competitive share of voice
- -- Established platform with strong documentation
Limitations
- -- Expensive entry point ($99/mo minimum)
- -- No free tier
- -- Measurement only -- no content generation
- -- Manual query setup required
- -- Overkill for solo operators or small sites
Bottom line: Promptwatch is a serious tool for serious budgets. If you are an agency managing multiple client brands or an enterprise marketing team, the depth of analytics justifies the price. For smaller operations, the cost is hard to justify when cheaper alternatives cover the basics.
3. Otterly
Pricing: Starts at $29/mo (scales to $489/mo)
Otterly positions itself as an AI search analytics platform with a focus on tracking brand visibility across AI-generated answers. It offers a relatively affordable entry point compared to enterprise-focused competitors.
The tool monitors how your brand and competitors appear in AI search results, with dashboards for tracking changes over time. Otterly covers multiple AI platforms and provides alerts when your visibility changes significantly.
Strengths
- -- Affordable entry point ($29/mo)
- -- Multi-engine AI monitoring
- -- Change alerts and notifications
- -- Clean, intuitive interface
- -- Good mid-market positioning
Limitations
- -- No free tier
- -- No content generation features
- -- Higher tiers get expensive quickly ($489/mo)
- -- Manual query configuration
- -- No llms.txt integration
Bottom line: Otterly is a solid middle-ground option. Affordable enough for growing teams, capable enough for meaningful insights. If you want multi-engine tracking without enterprise pricing, Otterly is worth evaluating. Just know that you are paying for measurement only -- there is no content generation or optimization side.
4. AIclicks
Pricing: Starts at $49/mo (scales to $299/mo)
AIclicks differentiates itself by focusing on the click-through side of AI citations. While most tools track whether you are cited, AIclicks aims to measure whether those citations actually drive traffic to your website.
The platform combines AI citation monitoring with click attribution, helping you understand not just visibility but actual impact. This is a meaningful distinction -- being cited is good, but driving traffic from those citations is what matters for revenue.
Strengths
- -- Click-through attribution from AI citations
- -- Revenue impact measurement
- -- Multi-engine tracking
- -- Competitive citation analysis
- -- Reasonable pricing for mid-market
Limitations
- -- No free tier
- -- Click attribution requires additional setup
- -- No content generation or optimization
- -- Manual query management
- -- Attribution accuracy depends on user behavior
Bottom line: AIclicks is the right choice if proving ROI from AI citations is your primary goal. The click attribution angle is genuinely useful for marketing teams that need to justify AI SEO budgets. If you just need to know whether you are being cited, simpler tools will do.
5. Peec AI
Pricing: Starts at $99/mo (scales to $530/mo)
Peec AI takes a comprehensive approach to AI visibility, combining citation tracking with content analysis and optimization recommendations. The platform analyzes how AI systems interpret your content and suggests specific improvements.
Where Peec AI stands out is in the depth of its content analysis. It does not just tell you whether you are cited -- it explains why or why not, based on how AI systems process your content structure, authority signals, and topical coverage.
Strengths
- -- Deep content analysis and recommendations
- -- AI content interpretation insights
- -- Multi-engine tracking
- -- Comprehensive competitor analysis
- -- Strategic optimization guidance
Limitations
- -- Expensive ($99/mo minimum)
- -- No free tier
- -- Steep learning curve for the analytics
- -- No llms.txt generation or hosting
- -- Better suited for teams with existing AI SEO knowledge
Bottom line: Peec AI is a strong choice for teams that want strategic guidance alongside their tracking data. The content analysis features go beyond simple citation counting. But the $99/mo entry price and complexity make it a poor fit for small businesses just getting started with AI visibility.
Pricing Comparison: What You Actually Pay
Pricing in this category varies dramatically. Here is what each tool costs at its entry and top tiers, so you can compare apples to apples.
| Tool | Entry Tier | Mid Tier | Top Tier | Annual Cost (Entry) |
|---|---|---|---|---|
| llmstxt.studio | Free | $19/mo | $49/mo | $0 |
| Otterly | $29/mo | -- | $489/mo | $348 |
| AIclicks | $49/mo | -- | $299/mo | $588 |
| Promptwatch | $99/mo | $249/mo | $579/mo | $1,188 |
| Peec AI | $99/mo | -- | $530/mo | $1,188 |
The price gap is significant. At the entry level, llmstxt.studio's free tier costs literally nothing. Even our Premium plan at $49/mo is cheaper than the entry-level plans at Promptwatch and Peec AI. Over a year, the difference between a free tool and a $99/mo tool is $1,188.
That said, cheaper is not always better. If you need multi-engine tracking across ChatGPT, Perplexity, and Gemini simultaneously, you will need to pay for it. The question is whether the additional coverage is worth 2-10x the cost for your specific situation.
What Makes llmstxt.studio Different
Every other tool on this list is measurement-only. They tell you whether AI cites your website. That is valuable, but it leaves you with a follow-up question: what do I do about it?
llmstxt.studio is the only tool that handles the full lifecycle:
Generate
Create a spec-compliant llms.txt file from your website content
Monitor
Track sitemap changes and flag when your content goes stale
Enhance
AI-powered descriptions that make your content more citable
Measure
Run citation checks with auto-generated queries and track trends
With measurement-only tools, you get a report that says "AI is not citing you." Then you have to figure out what to do on your own. With llmstxt.studio, the generation and enhancement features give you a direct path to improving the measurement results.
The tradeoff is clear: we track one AI engine, not multiple. If multi-engine coverage is critical for your use case, one of the other tools on this list is a better fit. But for most small and mid-sized businesses, understanding whether AI cites you is more important than checking five different engines simultaneously.
Which Tool Is Right for You?

Start with llmstxt.studio. The free tier gives you 3 citation checks to see where you stand. If the data is valuable, the Pro plan at $19/mo is the cheapest way to keep tracking.

Look at Promptwatch or Peec AI. The enterprise features, multi-engine coverage, and detailed reporting justify the higher cost when you are managing multiple brands or reporting to stakeholders.
You want the full lifecycle, not just measurement
llmstxt.studio is the only option that generates AI-readable content, monitors your site, and measures citation impact in one platform. If you want to improve your AI visibility, not just measure it, this is the tool to start with.
Frequently Asked Questions
What is AI citation tracking?
AI citation tracking monitors whether AI search engines like ChatGPT, Perplexity, and Claude cite your website when answering questions related to your industry. These tools query AI engines with relevant prompts and check whether your domain appears in the sources or citations.
How much do AI citation tracking tools cost?
Pricing varies widely. llmstxt.studio starts free and goes up to $49/month. Otterly starts at $29/month. AIclicks starts at $49/month. Promptwatch and Peec AI both start at $99/month. Enterprise plans at some tools exceed $500/month.
Do I need an AI citation tracking tool if I already do SEO?
Traditional SEO tools track Google rankings, not AI citations. AI search engines decide independently which sources to cite, and their criteria differ from Google's ranking factors. If potential customers use AI search to find businesses like yours, you need visibility into whether AI recommends you or your competitors.
Which AI citation tracking tool is best for small businesses?
For small businesses and solo operators, llmstxt.studio offers the best value with a free tier and Pro plan at $19/month. Otterly is another affordable option starting at $29/month. Tools like Promptwatch and Peec AI, which start at $99/month, are better suited for agencies and enterprises.
What is the difference between AI citation tracking and traditional rank tracking?
Traditional rank tracking monitors your position in Google search results for specific keywords. AI citation tracking monitors whether AI assistants cite your website when generating answers. There are no "positions" in AI search -- either your site is cited as a source or it is not. AI citation tools track this binary outcome across different query types and over time.
