Quick Verdict
Both Promptmonitor and Radix tackle the same problem: tracking how often AI models mention your brand or cite your content. But they take completely different approaches to get there. Promptmonitor focuses on being a comprehensive, budget-friendly solution that covers 8+ LLMs right out of the box, while Radix emphasizes precision testing and deeper analytics integration.
The choice comes down to whether you want broad coverage at a known price point or specialized benchmarking capabilities. Promptmonitor gives you immediate visibility across ChatGPT, Claude, Gemini, Grok, DeepSeek, and Perplexity for $29/month. Radix offers more sophisticated prompt testing and competitor analysis, but keeps its pricing behind closed doors.

Feature Comparison
Promptmonitor covers more ground with less complexity. You get tracking across 8+ major LLMs, plus unique features like publisher contact extraction from AI-cited sources and an llms.txt generator. The platform includes unlimited team seats even on the starter plan, which is rare in this space. Their AI crawler analytics help you understand which bots are indexing your content for AI training. Radix takes a different approach with prompt testing and brand recommendation counting. Instead of just monitoring mentions, they actively test how often AI models recommend your brand compared to competitors. Their citation tracking connects to existing analytics platforms, so you can see AI visitors alongside traditional traffic sources. The competitor benchmarking feature lets you see exactly how you stack up when users ask for product recommendations in your category.
Pricing Comparison
Promptmonitor's pricing is straightforward: Starter at $29/month, Growth at $39/month, and Pro at $129/month. You know exactly what you're paying upfront, and even the cheapest tier includes all major LLM tracking. The unlimited team seats on every plan means you won't get hit with per-user fees as you scale. Radix keeps their pricing private, requiring a demo call to get quotes. This typically signals enterprise-focused pricing that's significantly higher than Promptmonitor's transparent tiers. Without published rates, it's impossible to budget accurately or compare value per dollar.
Best For
Promptmonitor works better for smaller teams and agencies that need immediate AI visibility tracking without breaking the bank. The broad LLM coverage means you won't miss mentions across different platforms, and the publisher contact extraction actually helps you build relationships with sites that cite your content. If you want to start tracking AI mentions next week without a sales call, Promptmonitor gets you there faster. Radix fits teams that already have sophisticated analytics setups and need AI data to integrate with existing dashboards. The prompt testing approach gives you more control over what you're measuring, and the competitor benchmarking provides strategic insights beyond just mention counting. If you're comparing AI visibility as part of a broader competitive intelligence program, Radix offers more depth.
The Verdict
Promptmonitor wins for most use cases because of transparent pricing and immediate value. You get comprehensive LLM tracking for $29/month with features you can't find elsewhere, like publisher contact extraction. Radix might offer more sophisticated analytics, but hidden pricing and limited feature transparency make it harder to justify. Start with Promptmonitor's free tier and test their tracking across your target keywords — you'll know within a week if their coverage meets your needs.
