Feature Comparison
Authoritas stands out with its AI Composer for prompt discovery and negative prompt framing capabilities. You can create custom prompts to test specific scenarios and monitor how AI systems respond to reputation-damaging queries about your brand. The platform tracks citations across Google AI Overviews, Bing Copilot, SearchGPT, ChatGPT, Gemini, and Claude with multi-language support. Otterly AI covers the major platforms — ChatGPT, Google AI Overviews, Perplexity, Gemini, and Copilot — but adds useful integrations like Looker Studio connectors and Semrush App Store availability. Their GEO Audit tool shows location-based variations in AI responses, which Authoritas doesn't explicitly offer. Otterly also provides weekly link tracking and brand sentiment analysis as standard features. The biggest difference is customization depth. Authoritas lets you build complex monitoring scenarios with custom prompts, while Otterly focuses on comprehensive out-of-the-box tracking that requires minimal setup.
Pricing Comparison
Authoritas starts free with comparison tools against 100+ AI search platforms, making it easier to evaluate before committing to paid plans. Their enterprise heritage shows in the pricing structure — you'll likely pay more for advanced features, but the free tier gives you substantial testing capabilities. Otterly AI starts at $29 monthly after their free trial period. For agencies, they offer white-label capabilities and partner programs, which Authoritas doesn't prominently advertise. If you're running an agency that needs to present AI monitoring under your own brand, Otterly's partnership structure provides more flexibility.
Best For
Authoritas works better for enterprise brands with technical teams who want granular control over AI monitoring scenarios. The custom prompt capabilities and negative framing features are particularly valuable for companies dealing with reputation management or complex competitive landscapes. Their London base and enterprise focus also appeal to European companies wanting local support. Otterly AI suits marketing teams and agencies who need comprehensive AI monitoring without technical complexity. The 20,000+ user base suggests they've nailed the ease-of-use formula. Their Vienna headquarters and Semrush integration make them attractive for agencies already using Semrush workflows.
The Verdict
Choose Authoritas if you need advanced customization and don't mind a steeper learning curve. Their prompt engineering capabilities and enterprise features justify the complexity for brands with sophisticated monitoring needs. But Otterly AI wins for most marketing teams who want comprehensive tracking that works immediately. Start with Otterly's free trial to see if their pre-built monitoring covers your needs, then consider Authoritas if you hit limitations with custom scenarios.
