Questions people ask when choosing
New to this? Start with what AI search visibility is and how it's measured.
What are AI search visibility tools?
Tools that ask AI answer engines such as ChatGPT, Perplexity, Gemini and Google's AI Overviews the questions your buyers ask, then record whether the answers name your brand, which pages they cite and how you compare with competitors. Some also show AI crawlers reading your site, and a few help you change the result.
Which AI search visibility tool is best?
Letter scores highest overall (8.4 of 10) because it tracks citations, exposes everything through an API and MCP on every plan, publishes its prices and ships fixes as pull requests. If you want a no-code dashboard instead, Peec AI and Otterly.AI fit better; if you already use Ahrefs, Brand Radar is the strongest research tool.
Can I track AI citations for free?
You can start without paying: AthenaHQ has a free plan, Letter gives 1,000 free tokens with no card, SE Ranking a 14-day trial with no card, Profound a 7-day trial, and Peec AI, Otterly.AI, Scrunch and Writesonic offer free trials. Semrush's standalone toolkit lists no free trial. Terms change, so check each pricing page linked in the reviews.
How much do AI search visibility tools cost?
Published entry prices checked for this ranking run from €29 a month (Otterly.AI Lite) and $25 a month (Letter Hobbyist) to $295 a month (AthenaHQ Starter); Profound lists no paid price. Plans differ in prompts, engines and whether the API is included, so compare like for like in the comparison table.
Which answer engines should I track?
The ones your buyers use. For most teams that is ChatGPT, Google AI Overviews and AI Mode, Perplexity and Gemini; add Claude, Copilot or regional engines if your audience uses them. Check whether the engines you need are in the base plan or an add-on.
Do these tools show real people finding me through AI?
Mostly no. Prompt tracking measures sampled answers to questions the tool asks, not what real users saw. To see real visits from AI answers and AI crawlers reading your pages, you need data from your own site: Letter, Profound, Peec AI, Scrunch and Writesonic report crawler or AI-referral traffic in some form.
Which tools have an API or an MCP server?
Letter has API, CLI and MCP on every plan. Peec AI has MCP on every plan and an API from Pro; SE Ranking lists both with MCP on all plans; Otterly.AI from Standard; AthenaHQ has MCP with the API as an add-on; Profound and Scrunch on Enterprise. See the API & MCP column on the comparison table.
How do I check a score for myself?
Every review lists the official pages its facts came from and the date they were checked. Each criterion on the criteria page says what to look for on those pages. If a vendor's page now says something different, the page wins until the next review.
