Our verdict

Wintermute lets you ask questions about a web page, PDF, custom text, or an image, then switch to generating SMM content, ads, blog posts, or personalized emails from templates, plus a beta Reddit research tool. It's aimed at marketers and researchers who want one assistant covering both analysis and content creation. Anthropic Claude and Google Gemini support are still coming rather than available now, using your own API key is required for the free-with-your-key path, and Reddit research is explicitly labeled beta.
