Writesonic

Semrush started in 2008 as an SEO tool. It launched its AI search offering, AI Visibility Toolkit, in September 2025. The AI Visibility Toolkit is an add-on to Semrush's suite of SEO products. It covers a wide range of AEO use cases related to monitoring and auditing. Users can also use the Semrush Content Toolkit to produce AI-generated content.

Writesonic is a generative AI platform with over 5 million users. AI Search Visibility (GEO) tracks how often a brand appears in AI-generated answers across ChatGPT, Google AI Overviews, Perplexity, Gemini, Claude, and other platforms. Powered by 120M+ real AI conversations.

Worth noting

As an extension of Semrush's core SEO platform, the AI Visibility Toolkit focuses on keyword-focused reporting versus prompt-level analysis.

Worth noting

Writesonic is a content platform first, with GEO as a secondary feature. Best for teams that need a steady stream of marketing copy across multiple formats. Requires 30 days of data collection before insights become reliable.
