Quick Verdict
Otterly AI and Semrush AI Toolkit both track your brand's visibility across AI search platforms, but they target different audiences. Otterly built their entire business around AI monitoring since 2023, while Semrush launched their toolkit in 2024 as an add-on to their existing SEO suite.
The core difference isn't subtle — Otterly costs $29/month and includes a free tier, while Semrush charges $99/month per domain with no free option. That pricing gap reflects different philosophies: Otterly wants to democratize AI monitoring for smaller brands, while Semrush targets enterprise clients already paying for their SEO tools.

Feature Comparison
Otterly AI covers six AI platforms (ChatGPT, Google AI Overviews, AI Mode, Perplexity, Gemini, and Copilot) with their GEO Audit tool that tracks location-based visibility differences. Their weekly link tracking catches new citations as they appear, and the Looker Studio connector lets you build custom dashboards. The platform also includes brand sentiment analysis and a Semrush App Store integration that ironically works alongside Semrush's own data. Semrush AI Toolkit focuses on three core platforms (ChatGPT, Google AI Mode, and Perplexity) but integrates deeply with Semrush's existing SEO tools. Their AI prompt tracking feature lets you see exactly which queries trigger your brand mentions, and they identify technical website errors that prevent proper LLM crawling. The My Reports feature unifies AI monitoring with traditional SEO metrics in a single dashboard. Both tools offer competitive share of voice tracking and brand perception insights, but Otterly's coverage is broader while Semrush's integration is deeper. Semrush wins on technical SEO connections — their crawler error identification helps fix issues that hurt both traditional and AI search visibility.
Pricing Comparison
Otterly starts at $29/month with a free tier that covers basic monitoring across all six platforms. Their paid plans scale based on keyword volume and reporting frequency, making it accessible for small agencies and individual consultants. Semrush charges $99/month per domain on top of your existing Semrush subscription. If you're already paying $120+ monthly for Semrush Pro, adding AI monitoring nearly doubles your bill. But if you're a heavy Semrush user, the unified reporting and shared data sources eliminate tool switching overhead.
Best For
Otterly AI works better for agencies managing multiple clients, smaller brands testing AI monitoring for the first time, or anyone who needs broader platform coverage. The white-label capabilities and agency partner program make it the obvious choice if you're selling AI monitoring services to clients. I've seen agencies use Otterly's free tier for prospect demonstrations before upgrading client accounts. Semrush AI Toolkit makes sense if you're already deep in the Semrush ecosystem and need AI data to flow into existing workflows. Enterprise marketing teams who rely heavily on Semrush's other tools will appreciate the unified interface, and the technical crawler insights help SEO teams fix issues that impact both traditional and AI search.
The Verdict
Choose Otterly AI unless you're a committed Semrush enterprise user. The $70 monthly savings buys a lot of other tools, and Otterly's broader platform coverage catches mentions Semrush misses on Gemini and Copilot. Start with Otterly's free tier to test AI monitoring for your brand, then upgrade based on your actual usage patterns.
