What both leave out
Open questions on each side, from the same rendered pages. Semrush: aI visibility is one metered module inside a big suite; grok and DeepSeek absent from the published list; white-labeling is a $20/mo add-on. Surfer: claude, Grok and DeepSeek absent from the engine list; no local surface of any kind; workflow ends at the graded draft.
Rank.ai is built for the loop that usually falls between these two products. It puts your market’s buying questions to seven AI engines every day, ChatGPT, Claude, Gemini, Perplexity, Grok, Google AI Overviews and DeepSeek, three samples per engine, and records every answer with the brands named and the sources cited. It checks your Google rankings daily on every plan and scans a geo-grid of your Google Maps rank across your service area. And it finishes the job: the article pipeline researches, writes and publishes the missing pages into WordPress, Webflow, Shopify or WordPress.com with your approval, 10 a month included on the $0 plan.
