Since 2025 it also ships an AI Search Analytics module that tracks brand and page visibility inside ChatGPT, Perplexity and Google AI answers. Used by content teams, agencies and freelance SEOs planning and optimizing articles at scale.

Typical jobs: Optimizing blog articles against top-10 competitors; Agency content production at scale; Tracking brand mentions in AI answer engines.
Worth knowing: No permanent free tier; 7-day money-back guarantee requires card and paid signup, not a true free trial. Prices shown in EUR (Surfer's default currency).
What users complain about: Expensive compared to competitors, with platforms like Frase and Scalenut offering much better value for money. (searchatlas.com review)

Where it wins

- Added a standalone AI Search Analytics product to track visibility in ChatGPT/Perplexity/Google AI
- Deep integrations (WordPress, Google Docs, Surfer AI writer) and active feature releases since 2017
Where it falls short

- Users report unused AI writing credits being non-refundable when plans change or lapse
- Heavy reliance on the optimization score can push writers toward keyword-stuffed, less readable copy, per Reddit discussion
