Feature Comparison
Promptmonitor's standout feature is publisher contact extraction — when an AI cites a source that mentions your brand, you get the contact details to build relationships with those publishers. That's genuinely useful for PR and link building. They also include an llms.txt generator and AI crawler analytics, plus unlimited team seats across all plans. Mentions.so takes a different angle by measuring actual visitor traffic from AI referrals rather than just tracking mentions. Their auto-generated insights and branded reports are designed for agencies managing multiple clients. The white-label reporting on their Agency plan ($399/mo) lets you rebrand everything for client delivery. Both track the major models like ChatGPT, Claude, and Gemini, but Promptmonitor covers more emerging LLMs. Mentions.so focuses on the traffic impact rather than breadth of coverage.
Pricing Comparison
Promptmonitor starts at $29/mo with a free tier available, making it significantly cheaper for getting started. Their Growth plan at $39/mo and Pro at $129/mo still undercut Mentions.so's entry point. Plus unlimited team seats on every plan means no per-user costs. Mentions.so starts at $49/mo with no free tier, making it 70% more expensive at the entry level. However, their Agency plan at $399/mo includes white-label reporting and bulk client management that agencies need. If you're managing multiple clients, that pricing makes sense.
Best For
Promptmonitor works better for content creators, small agencies, and anyone wanting comprehensive LLM coverage without breaking the budget. The publisher contact extraction is perfect for link builders, and the free tier lets you test before committing. If you need to track mentions across newer AI models or want unlimited team access cheaply, this is your pick. Mentions.so suits agencies and larger teams who need to prove actual traffic impact from AI mentions. The visitor tracking and branded reporting justify the higher price if you're billing clients or need to show ROI numbers to stakeholders. The white-label option is essential for agencies.
The Verdict
Promptmonitor wins on value and feature breadth — you get more LLM coverage, unique publisher tools, and unlimited seats for less money. But Mentions.so delivers better insights for agencies who need to track actual business impact rather than just mentions. Start with Promptmonitor's free tier to test the waters, then consider upgrading to Mentions.so if you need visitor tracking and client reporting features.
