top 8 ai visibility platforms ranked
The best AI visibility platform is the one that measures enough to point you at the right strategy. AI models are non-deterministic, so the same question asked twice can come back differently. A small sample does not just produce a noisy number, it points you at the wrong problem. These are entry-level plans at their lowest published rate, ranked by how many AI answers one complete measurement collects.

Google AI means Google AI Mode and Google AI Overviews counted as one search surface, since vendors split them inconsistently.
1 Ahrefs Brand Radar Ahrefs sells checks rather than a prompt count: one check tracks one prompt on one platform in one location. The $100 Growth package covers 7,000 a month, which Ahrefs sizes as “100 prompts daily on 2 platforms.” Its own 475M-prompt database is sold separately, at $199 per platform or $699 for all five.
2 Semrush Semrush prices its AI visibility plan per domain, and the Base plan covers one domain for Brand Performance analysis.
3 Peec AI Peec includes three engines on Starter, chosen from its menu of five. Additional engines are $30 per month each. Claude is Enterprise-only and Grok is not offered on any tier.
4 Otterly.AI Otterly’s cheaper Lite plan is $25 per month billed annually but covers only 15 prompts. Standard is shown here as the more comparable tier. Claude, Gemini, and Google AI Mode are paid add-ons on every Otterly plan.

how to choose an ai visibility platform
Six things to check before you buy, and how Centium compares on each. Every one of them is answerable from a published pricing page or a short demo. The things that decide how accurate your numbers are can all be verified up front.
Measure the total prompts you receive. Multiply the unique prompts by the number of AI models to get the true size of one measurement. AI models are variable in how they answer, so a larger sample produces a more accurate visibility percentage. Centium delivers 720 total AI responses per report, the highest volume in this comparison. We prioritize deeper measurement, done less often.
Verify how many models you are tracking. Each one uses a different search index, so they all behave a little differently and a missing model is a blind spot rather than a rounding error. Centium measures the six leading AI models, representing over 95% of AI usage.
Ask whether you have to name your competitors up front. Most platforms make you configure a list, so you only ever learn about the rivals you already knew. Centium captures every brand the models raise on their own, ranked by how often they appear, up to 100 per category.
See what features your plan includes. Many platforms withhold their best work for premium accounts, query fan-out among them. Centium provides the full platform to every user. The only thing that changes between plans is how often your data refreshes.
Check the seat limits. Caps turn a shared measurement into one person’s login, and most entry plans are tight. Centium provides unlimited seats plus shareable encrypted links. Bring your team, your agencies, and your board into the dashboard without restrictions.
Ask whether the data is yours. A platform you cannot export from is a platform you cannot leave. Centium allows full export access across every dashboard feature, and archives your past results so earlier reports stay available.
what buyers ask.
Centium ranks first among entry-level plans, measured by how many AI responses each plan collects in one complete measurement. Centium runs 120 prompts across six AI models starting at $99 per month, producing 720 responses. Every Centium plan includes the full platform and all features, with unlimited seats.
Centium is the only major platform that includes Claude in all plans. Otterly.AI offers Claude as a paid add-on. Profound, Peec AI, Scrunch AI, Semrush, HubSpot, and Ahrefs Brand Radar do not cover Claude at their entry tiers.
Entry-level plans in this comparison range from $50 to $250 per month. HubSpot AEO is $50 per month, Peec AI Starter is $80 per month billed annually, Centium is $99 per month billed annually, Profound Starter is $82.50 per month billed annually, Ahrefs' Growth prompt package is $100 per month, Semrush's AI Visibility Base plan is $99 per month per domain billed annually, Otterly.AI Standard is $160 per month billed annually, and Scrunch AI Core is $250 per month.
Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) describe the same practice: improving how a brand is represented when AI models answer questions. AEO frames the work around the answer a model gives. GEO frames it around the generative system producing that answer. Most platforms in this category use the terms interchangeably.
Not at the entry tier. All eight platforms compared here sell an entry-level AI visibility plan that can be bought on its own, including Semrush and Ahrefs, which both also sell broader SEO suites. The constraints to check are elsewhere: Semrush prices per domain and its Base plan covers one, Ahrefs sells prompt tracking as a usage-based package, and Profound Starter includes a single seat.
Enough that one unusual answer does not move the result. Entry plans in this comparison range from 25 prompts to 125 prompts per measurement. AI models are variable, so the same question asked twice can come back differently. The number that matters is prompts multiplied by models, because that is how many AI responses stand behind your visibility percentage. A larger sample is simply a more accurate one. Centium runs 720 responses per measurement at its entry plan, the highest in this comparison.
An AI visibility platform measures how AI models describe and recommend a brand. It runs a set of prompts against models like ChatGPT, Claude, Gemini, Perplexity, and Grok, then reports how often the brand comes up, which competitors appear alongside it, and which sources the models cite. The category is also called AEO (Answer Engine Optimization) or GEO (Generative Engine Optimization) tooling, and vendors use the three terms interchangeably. Centium runs 120 prompts across six AI models on every plan.
