What Does an AI Visibility Checker Measure?
An AI visibility checker measures whether a brand gets mentioned, linked, or recommended inside answers generated by tools like ChatGPT, Gemini, Perplexity, and Google AI Overviews. Most checkers track the same core set of signals, even though they package them differently.
- Mentions: The brand name appearing somewhere in the AI’s answer text
- Citations: A linked source the AI pulled from to build that answer
- Share of Voice: How often a brand appears against named competitors for the same set of questions
- Sentiment: Whether the AI’s answer frames the brand positively, neutrally, or negatively
Checkers also record whether an answer came from a live web search or straight from the model’s training data, since that detail changes how fixable a visibility gap actually is.
Prominent Orange, Semrush AI Visibility Toolkit, Ahrefs Brand Radar, and Otterly.AI are the top AI visibility checker tools for 2026, with Prominent Orange as the best choice for agencies that need a shareable, client-branded buyer-question audit.

Top 4 AI Visibility Checker Tools for 2026
1. Prominent Orange: Best for Agency Client Audits
Prominent Orange is a white-label AI visibility audit tool built for agencies. You paste in a business website, and the tool pulls dozens of real buyer questions from that site and its market, then runs around 200 live queries across ChatGPT, Claude, Gemini, Perplexity, and Google AI. The questions are grouped by buying stage, so the report shows where the brand gets named as buyers move closer to a purchase. A walkthrough of how Prominent Orange tracks AI citations explains how each report is built.
Each full report opens with a head-to-head competitor comparison, then shows real AI answers, a share-of-voice ranking, a six-month citation index, and sentiment scores for how AI describes the brand. It checks questions that use the brand’s own name separately, maps the website’s topics against what buyers actually ask, and ranks each gap by buying intent. It groups and counts name variants, such as a company name and its domain, as one brand.
On the Agency plan, reports carry the agency’s logo, byline, subdomain, and booking or payment link, with 12 full reports and 750 prospect teasers a month. Solo and Growth plans are tracking-only, without that branding. Each report is a point-in-time snapshot of sampled questions, so trends only appear when you compare saved reports month over month.
2. Semrush AI Visibility Toolkit: Best for Existing Semrush Users
Semrush’s AI Visibility Toolkit sits within its larger marketing platform and includes Visibility Overview, Brand Performance, Competitor Research, Prompt Research, and Position Tracking.
Visibility Overview benchmarks a brand using Semrush’s prompt database, and Brand Performance reviews branded and unbranded prompts across five AI platforms each week. Position Tracking checks a chosen list of keywords and prompts daily.
The toolkit suits teams already using Semrush for search. Because each report uses its own data source and refresh schedule, new users need time to learn which report answers which question.
3. Ahrefs Brand Radar: Best for Prompt Index Plus Custom Prompts
Ahrefs Brand Radar works in two modes: AI Visibility Index and Custom Prompts. The Index searches pre-collected answers from search-backed prompts across AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini, and Copilot, with question sets retested monthly. Custom Prompts runs questions the user writes on a daily, weekly, or monthly schedule, per platform and location.
The Index suits brands and topics with meaningful search demand, while newer or niche brands may find its coverage thin and do better with Custom Prompts. The two modes use different datasets and schedules, so you shouldn’t read their numbers as a single measurement.
4. Otterly.AI: Best for Daily Prompt Monitoring
Otterly.AI monitors a defined prompt list daily through four tools: AI Prompt Research, AI Search Analytics, Content Audit, and GEO Optimization. Together, they cover question research, answer tracking, and content recommendations, along with brand visibility, sentiment, citation sources, and brand profiles.
Self-serve plans track ChatGPT, Google AI Overviews, Perplexity, and Microsoft Copilot by default, while Claude, Google AI Mode, and Gemini are available as add-ons. Otterly.AI works best for teams that want daily monitoring with citation and competitor reporting, as long as their plan covers the assistants their buyers actually use.

Frequently Asked Questions (FAQs)
What is the difference between AI visibility and search rankings?
Search rankings show where a page appears on a results page for a typed keyword. AI visibility shows whether a brand is mentioned, linked, or recommended in a conversational answer from tools like ChatGPT or Gemini. Those answers can draw on different signals than a results page, so the two need separate checks.
Can I check my brand’s AI visibility manually?
Yes, you can ask the same buyer-style question in a few AI assistants and note the date, location, and settings used. Record brand mentions, linked sources, and competing brands for each answer. Repeat the check on a schedule, since a single response never gives the full picture.
Do mentions and citations mean the same thing?
No, a mention is your brand name appearing in the AI’s answer text, while a citation is a linked source the AI pulled information from. A brand can be mentioned without being cited, or cited without being named in the visible answer.
How often should I check AI visibility?
The right schedule depends on your goal, and a quarterly or one-time audit works well for reporting to clients or leadership. Brands actively closing visibility gaps benefit from weekly or daily tracking, though you still need to measure website visits separately.
How does AmpiFire help after an AI visibility audit?
At AmpiFire, we start with the buyer questions an audit flags and research the topics buyers search before they purchase. Our AmpCast AI platform then turns each topic into answers in various formats before automatically publishing them across hundreds of sites, including your website and connected social channels. A comparable audit run later shows how your brand’s presence in AI answers has changed.
