Marvlus
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.
Pros
- Combines AI-visibility auditing with conventional Google rank tracking in one product
- Free tier lets you run a real homepage audit before paying
- White-label option specifically built for agency resale
Cons
- Paid tiers cap prompts and topics tightly (80 prompts on the $29 plan)
- Built and apparently run by a single founder, a risk for long-term support
- AI-visibility scoring methodology is not independently verified
