AI visibility monitoring tools: a 2026 review and comparison

2025 was the year the AI visibility tooling market exploded. In 2023 there was no dedicated tool for tracking share of voice in ChatGPT or Perplexity; today more than 30 products compete in the category. The problem is no longer a lack of choice - it is finding your way through the thicket to a tool that matches your needs and budget.

This guide compares tools by model coverage, data quality, language support, price and fit. If you want to establish the scope first, use our benchmark qualification. Full measurement is part of a Snapshot or an audit.

What should an AI visibility tool monitor?

Before the tools themselves, it is worth setting the assessment criteria. A good AI visibility tool should monitor at least:

• Share of Voice - what percentage of AI answers to your keywords name your brand. This is the core AI visibility metric.
• Citation frequency rate - how often your site is cited as a source, particularly in Perplexity and ChatGPT Search where links are visible.
• Sentiment analysis - whether mentions are favourable, neutral or unfavourable. You can be cited often but in a negative context.
• Competitor comparison - your share of voice alone says little. What counts is relative: if you are at 30% and the market leader at 70%, there is room to improve.
• Model coverage - the tool should monitor at least ChatGPT, Perplexity, Google AI Overviews and Gemini. Monitoring one model gives an incomplete picture.
• Alerts and trends - notifications when share of voice falls significantly or a new competitor appears in AI answers.

A comparison table

Profound - the most mature enterprise option

Profound is currently the most comprehensive tool on the market. It monitors five AI systems at once - ChatGPT, Perplexity, Gemini, Claude and Bing AI - and offers detailed share-of-voice reports broken down by query category, with competitor comparison. Its prompt-testing module stands out: you can add your own questions that the model asks regularly, and measure the answers.

Strengths: the widest monitoring coverage, a good API, exportable reports and support for European languages. Weaknesses: price - the enterprise plan starts at USD 199 a month, which can be a barrier for smaller companies. The interface is extensive and takes learning. For agencies managing several clients, the agency plan is justified.

Otterly.AI - the most accessible for small companies

Otterly.AI focuses on simplicity and affordability. The entry plan at USD 29 a month covers brand monitoring in ChatGPT, Perplexity and Gemini, email alerts on significant changes and a basic dashboard with trends. The interface is intuitive and can be running in 15 minutes.

Limitations: no advanced competitor analysis - it tracks your own brand only. For companies just starting to measure AI visibility, it is a good starting point.

AthenaHQ - for enterprise with demanding requirements

AthenaHQ is designed for large organisations with dedicated marketing teams. What distinguishes it is deep analysis of the reasons for citation - the tool tries to explain why AI names particular brands, analysing credibility and topical-fit factors.

The USD 199 monthly entry price is a barrier. AthenaHQ suits environments where AI visibility is already an established board-level metric and detailed reports for stakeholders are needed.

ZipTie.dev - the Google AI Overviews specialist

ZipTie occupies a distinctive niche: it specialises in monitoring Google AI Overviews. If your priority is visibility in Google results with an AI summary, ZipTie is the dedicated tool. It tracks whether your page is cited in an AI Overview for given keywords, and shows which passage is cited.

The limitation: ZipTie monitors only ChatGPT and Google AIO - not Perplexity, Gemini or Claude. For companies focused mainly on Google presence, where AI Overviews are increasingly common, it is a good complement to standard SEO tooling.

Language coverage matters more than the feature list

Most tools were built for English-language queries first. If your buyers search in another language, check three things before subscribing: whether the tool handles queries in that language accurately, whether its source coverage includes local publications, and whether the reporting distinguishes results by language. A tool with excellent English coverage can produce misleading numbers for a market it barely indexes.

How to choose - a decision framework

The choice should follow from a few specific questions:

• Do you need monitoring in a language other than English? Check source coverage for that market before committing.
• What is your budget? Under USD 50 a month: Otterly.AI, Peec AI or ZipTie. Above that: Profound or AthenaHQ.
• Is Google AIO your priority? ZipTie, or Profound with the Google module.
• Do you run an agency managing several clients? Profound's agency plan or an Otterly.AI team plan.
• Do you need an API to integrate with your own dashboard? Profound or AthenaHQ.
• Are you just starting and want to understand what AI visibility is? Otterly.AI's entry plan has the gentlest learning curve.

The alternative: manual monitoring with no tooling

If budget is tight, you can build a simple monitoring system by hand. It will not replace dedicated tooling, but it gives a baseline at no cost:

1. 1Create a spreadsheet listing 20 to 30 category questions related to your offer
2. 2Once a month, ask each question in ChatGPT (without browsing), Perplexity and Gemini
3. 3Record whether your brand appears, whether competitor X appears, and the context of the mention
4. 4Calculate a simple share of voice: answers containing your brand divided by all queries, times 100
5. 5After three months you have a trend - rising, falling or flat

The drawbacks of the manual approach: it is labour-intensive at around three to four hours a month, it does not provide real-time alerts, and it has no competitor comparison. But before you invest in a tool, it is a good way to verify whether AI visibility is a problem for your company at all.

Newer entrants: Nightwatch, Keyword.com and Scrunch

The AI visibility tooling market changes quickly. Several new products have gained traction among SEO teams:

Nightwatch is particularly interesting for SEO managers who want to track conventional Google positions and AI visibility in one dashboard. Combining both metrics in one place shows the correlation: whether a rise in SEO position translates into improved AI share of voice. Keyword.com is a good choice for teams already using it for rank tracking who want to add AI tracking without changing workflow.
