Audits how ChatGPT, Gemini, and Claude describe your site, alongside normal SEO tracking.
Marvlus scans a website the way an AI system would and reports what ChatGPT, Gemini, and Claude are likely to say about it, then tracks whether the business actually gets mentioned across a set of prompts over time. It pairs that AI-visibility audit with conventional keyword rank tracking, so a team can watch both Google position and AI-answer presence from one dashboard. It also offers a white-label version agencies can embed on their own sites as a lead-generation audit tool. Marvin Russell, a Chicago-based SaaS founder, built it after running an SEO agency and repeatedly being asked what a client should actually fix next.
$29/month (Website Owner tier) covers a full site audit across 10 topics and 80 tracked prompts; the free tier covers one topic only.
Use tool ↗Marvlus sits in the fast-growing AI-visibility-tracking category, and the free tier is enough to run one real audit before deciding if the $29/month plan is worth it. Its edge over a plain SEO tracker is watching AI-answer mentions specifically, but that also means its core promise depends on how consistently AI models actually cite anything at all for a given niche.
