Otterly.ai is a Vienna-based, bootstrapped AI-search monitoring tool that launched in late 2024 and is known for two things: being genuinely easy to use and being the cheapest real entry point in the category at $29/mo. It tracks brand mentions, share of voice and citation sources across four core engines, with detailed categorization of which kinds of sites the AI engines cite. A Semrush technology partnership adds credibility.

Key features of Otterly.ai

  • Citation-source detail: breaks down which domains and types of sites (news, competitor, blogs) the AI engines cite.
  • Four core engines: ChatGPT, Google AI Overviews, Perplexity and Copilot on every plan, with Google AI Mode, Gemini and Claude as paid add-ons.
  • Brand Visibility Index: a share-of-voice metric with average position and a “Likelihood to Buy” score.
  • GEO audit: flags crawlability, content-readiness and structured-data gaps to fix.
  • Unlimited team members: on every plan, with white-label reports and Looker export.
  • Top-rated ease of use: strong G2 ease-of-use and support scores.

Who Otterly.ai is best for

Otterly.ai suits marketers and agencies that want an affordable, easy AI-search monitor for a handful of brands across the core engines, with clear citation-source detail. It is less suited to teams that need accurate sentiment, many per-engine add-ons, or automated fix recommendations, since it stays diagnostic and costs scale with add-ons. For a built-in action layer, compare Frase or AthenaHQ; for deeper metrics, Peec AI. See where it ranks in our best AI visibility tools guide.

What is Otterly.ai?

Otterly.ai is a Vienna-based AI-search monitoring tool, launched in late 2024 and bootstrapped, that tracks how brands appear in AI answers. It covers four core engines (ChatGPT, Google AI Overviews, Perplexity and Copilot), reports share of voice, average position and detailed citation sources, and is known for being one of the easiest and most affordable tools in the category.

How can I check the AI visibility of my website?

You can check AI visibility with a tool like Otterly.ai by adding your brand and a set of prompts, which it runs against the AI engines to show where and how often you appear, your share of voice versus competitors, and which sources are cited. Otterly’s low $29 entry plan and 7-day trial make it an easy, affordable way to start; free checkers from SE Ranking and Semrush are another zero-cost option.

Which AI engines does Otterly.ai track?

Otterly.ai includes four core engines on every plan: ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot. Google AI Mode, Google Gemini and Anthropic Claude are available as paid add-ons, so full seven-engine coverage costs extra.
