Otterly.ai is an excellent European entry point for monitoring mentions in AI answers, with a Lite plan at $29/month and daily tracking. But it is a monitoring tool, with no page audit module or prioritized action plan, and native coverage limited to 4 engines (Gemini and Google AI Mode as paid add-ons). If you want more engines, a free plan, or a platform that turns diagnostics into actions, here are the best Otterly alternatives in 2026. Hikoo leads as the complete European alternative.

Methodology
We compared each Otterly alternative on feature depth, ease of use, value for money and support, favoring engine coverage without add-ons, the presence of a free plan, depth (audit and action plan beyond plain monitoring) and a GDPR-compliant European footprint.
Conclusion
Otterly remains a good low-cost European monitoring tool, but it plateaus quickly if you want more engines or an action plan. Hikoo stands out as the most complete alternative, with a free plan, up to 9 engines, GDPR compliance and four modules from audit to action. Peec AI and Profound fit if you mainly want analytics or enterprise coverage. See also our comparisons of the best alternatives to Peec AI, Profound and HubSpot.
