Open questions on each side, from the same rendered pages. Ahrefs: claude and DeepSeek absent from the AI lineup; google rank updates are weekly on every tier; aI prompt tracking metered small on core plans.

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.
