Quick Verdict
The AI visibility tracking space heated up in 2025 as businesses realized their brands were being referenced (or ignored) in ChatGPT, Claude, and Google's AI Overviews. Two new platforms emerged to solve this problem: Promptwatch from Amsterdam and Mentions.so with its team-first approach.
Both track your brand mentions across major AI platforms, but they take fundamentally different approaches. Promptwatch leans technical with crawler log analysis and source attribution, while Mentions.so prioritizes team collaboration and actual traffic measurement from AI referrals.

Feature Comparison
Promptwatch covers more ground with tracking across ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews. Their crawler log analysis digs into how AI models discover your content, plus they attribute sources across YouTube and Reddit — useful if you're creating content on multiple platforms. The technical depth shows in their approach to understanding why certain content gets picked up by AI models. Mentions.so focuses on the business impact rather than the technical mechanics. Their standout feature measures actual visitor numbers referred from AI platforms, not just mentions. If you're running client campaigns, their white-label reporting on the Agency plan saves hours of manual report creation. Every plan includes unlimited team seats, which gets expensive fast on other platforms. The core difference: Promptwatch tells you what's happening and why, Mentions.so tells you what's driving actual traffic and revenue.
Pricing Comparison
Mentions.so starts at $49/month with no free tier, while Promptwatch offers a free tier before jumping to $89/month for Essential. But that price difference disappears when you factor in team size. Promptwatch likely charges per seat (though they don't specify), while Mentions.so includes unlimited users on every plan. For agencies, Mentions.so's $399/month Agency plan with white-label reporting competes directly with Promptwatch's $499/month Business tier. The $100 difference matters when you're managing multiple client accounts, especially since Mentions.so throws in bulk client management tools.
Best For
Promptwatch wins for technical SEOs and content strategists who need to understand the mechanics of AI visibility. If you're optimizing content specifically for AI platforms or need to track performance across YouTube and Reddit, their source attribution and crawler analysis provide actionable insights you won't find elsewhere. Mentions.so works better for agencies and marketing teams focused on ROI rather than technical details. The unlimited seats, white-label reporting, and actual traffic measurement make it easier to manage client expectations and demonstrate real business impact from AI visibility efforts.
The Verdict
Choose Promptwatch if you're a solo practitioner or small team that needs deep technical insights into AI platform behavior. The free tier lets you test their approach, and their funding from Arches Capital suggests they'll keep innovating on the technical side. Pick Mentions.so if you're running a team or agency where collaboration matters more than technical depth. Start with their $49 Starter plan and upgrade to Agency if you need client reporting — the unlimited seats alone justify the switch for most teams.
Our verdict
For features, promptwatch leads. On a budget, go with mentions-so.
