Overview

Promptwatch

Promptwatch is an end-to-end AI search visibility and optimization platform used by 7,000+ brands including Booking.com, Center Parcs, and Yelp. It doesn't just show you where your brand appears in AI responses -- it helps you fix the gaps. The platform combines monitoring across 10 AI models (ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews, Grok, DeepSeek, Meta AI, Mistral, Copilot) with Answer Gap Analysis that shows exactly which prompts competitors rank for but you don't, plus a built-in AI writing agent that generates content engineered to get cited by AI models. You also get AI crawler logs (see which pages ChatGPT and Claude are actually reading on your site), Reddit/YouTube insights, ChatGPT Shopping tracking, and traffic attribution to connect visibility to revenue.

The core difference: Promptwatch is built around an action loop -- find gaps, create content, track results. Most competitors stop at step one.

Mentions.so

Mentions.so is a brand mention tracking tool for AI search engines. It monitors how ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek, and Meta AI talk about your brand, with sentiment analysis and competitor comparison features. The platform offers a free tier (25 prompts across 3 LLMs) and paid plans starting at $249/mo. You can track custom prompts or use AI-suggested ones, compare your visibility to competitors, and get daily performance reports. Mentions.so also includes traffic tracking to see how much traffic comes from AI models.

The tool positions itself as a way to "dominate AI conversations" with actionable recommendations, though the depth of those recommendations isn't as clear as Promptwatch's content gap analysis and generation features.

Side-by-Side Comparison

Feature deep-dive

Monitoring coverage

Promptwatch tracks 10 AI models including Google AI Overviews and Mistral, which Mentions.so doesn't cover. Both track the major players (ChatGPT, Claude, Gemini, Perplexity), but Promptwatch's broader coverage matters if you're trying to capture the full AI search landscape. Google AI Overviews alone drives significant traffic for many brands.

Mentions.so's 7-model coverage hits the most popular LLMs, which is enough for most use cases. The free tier limits you to 3 models, so you'll need to pick your priorities.

Verdict: Promptwatch wins on breadth. If you need comprehensive coverage including Google's AI features, it's the only option.

Content optimization and generation

This is where the two tools diverge completely.

Promptwatch includes a built-in AI writing agent that generates articles, listicles, and comparison pages grounded in real citation data from 880M+ analyzed citations. The Answer Gap Analysis shows you exactly which prompts competitors rank for but you don't, then helps you create content to fill those gaps. You're not just monitoring -- you're actively improving your visibility.

Mentions.so gives you "practical recommendations" and daily reports with "clear strategies," but there's no content generation tool. You get insights about what's working or not working, but you're on your own to fix it.

Verdict: If you want to actually improve your AI visibility instead of just watching it, Promptwatch is the only choice here. Mentions.so is monitoring-only.

AI crawler visibility

Promptwatch's AI crawler logs show you in real-time when ChatGPT, Claude, Perplexity, and other AI bots hit your website -- which pages they read, errors they encounter, how often they return. This is critical for understanding whether AI models can even discover your content in the first place. If Claude is getting 404s on your key pages, you'll see it immediately.

Mentions.so doesn't offer this. You can see whether AI models mention your brand in responses, but you can't see whether they're successfully crawling your site.

Verdict: Promptwatch. Crawler logs are table stakes for serious AI SEO work.

Competitor analysis

Both tools let you compare your visibility to competitors.

Promptwatch shows competitor heatmaps across LLMs -- who's winning for each prompt and why. The Answer Gap Analysis specifically highlights prompts where competitors appear but you don't, with prompt volume estimates and difficulty scores so you can prioritize high-value opportunities.

Mentions.so shows competitor visibility percentages over time (e.g. "Kajabi 67%, Thinkific 59%") and lets you track how you stack up. The interface looks clean, but it's less clear how deep the analysis goes or whether you get actionable next steps beyond "competitor X is ranking higher."

Verdict: Promptwatch's gap analysis is more actionable. Mentions.so shows you the scoreboard, Promptwatch shows you how to win.

Traffic attribution

Promptwatch offers three ways to track AI-driven traffic: code snippet, Google Search Console integration, or server log analysis. You can connect visibility to actual revenue and see which pages are driving traffic from AI search.

Mentions.so includes traffic tracking to see how much traffic comes from AI models, but the implementation details are less clear. The website mentions "track AI traffic and see what's driving results," but doesn't specify the tracking method.

Verdict: Promptwatch's multiple attribution methods give you more flexibility and precision.

Unique features

Promptwatch has several features Mentions.so doesn't match:

• Reddit & YouTube insights: Surface discussions that influence AI recommendations. AI models cite Reddit threads and YouTube videos constantly -- Promptwatch tracks this, Mentions.so doesn't.
• ChatGPT Shopping tracking: Monitor when your brand appears in ChatGPT's product recommendations and shopping carousels. Huge for e-commerce brands.
• Prompt Intelligence: Volume estimates, difficulty scores, and query fan-outs that show how one prompt branches into sub-queries. Helps you prioritize.
• Citation & Source Analysis: See exactly which pages, domains, and content types AI models cite. Know where to publish.

Mentions.so's unique angle is the free tier, which is genuinely useful for small brands or solo founders who want basic monitoring without paying. The AI-suggested prompts feature is also nice -- you don't have to brainstorm every query yourself.

Verdict: Promptwatch has more depth. Mentions.so's free tier is its standout feature.

User experience

Promptwatch is feature-dense, which means a steeper learning curve. You're getting a full optimization platform, not just a dashboard. The interface is built for marketers and SEO teams who want granular control.

Mentions.so looks cleaner and simpler based on the screenshots. The "3 simple steps" positioning (add brand, pick prompts, get insights) suggests a more streamlined onboarding. Good for people who want to get started fast without a lot of configuration.

Verdict: Mentions.so is probably easier to start with. Promptwatch is more powerful but requires more setup.

Multi-language and regional tracking

Promptwatch explicitly supports multi-language and multi-region monitoring with customizable personas that match how your actual customers prompt. You can track AI responses in any language from any country.

Mentions.so doesn't mention this capability on their site. The interface shows a US flag in the workspace setup, but it's unclear whether you can track other regions or languages.

Verdict: Promptwatch if you operate internationally.

Pricing comparison

Promptwatch's pricing is more transparent and granular. You know exactly what you're getting at each tier. The $99/mo entry point is reasonable for small businesses, and the jump to $249/mo adds meaningful features (crawler logs, more sites, more prompts).

Mentions.so's free tier is a real differentiator -- 25 prompts across 3 LLMs is enough to get a sense of your visibility without spending anything. But the jump from $0 to $249/mo is steep, and we don't know what you get at that paid tier beyond the free limits. The lack of pricing transparency on the website is a downside.

Verdict: Mentions.so wins on entry barrier (free tier). Promptwatch wins on value and transparency at paid tiers.

Who should pick which tool

Pick Promptwatch if:

• You want to actively improve your AI visibility, not just monitor it
• You need content generation tools to fill gaps in your AI search coverage
• You're serious about AI SEO and want the most comprehensive feature set
• You need AI crawler logs to diagnose technical issues
• You track competitors closely and want detailed gap analysis with prompt volumes and difficulty scores
• You operate internationally and need multi-language/region tracking
• You're an e-commerce brand that needs ChatGPT Shopping tracking
• You want to connect AI visibility to actual traffic and revenue with attribution
• You have budget for a proper tool ($99-$579/mo depending on scale)

Pick Mentions.so if:

• You want basic brand mention monitoring without paying anything (free tier)
• You're a small brand or solo founder testing the waters with AI search
• You prefer a simple, clean interface over feature depth
• You don't need content generation -- you just want to track what AI says about you
• You're okay with monitoring-only and will handle optimization yourself
• You only care about the top 3-7 AI models and don't need comprehensive coverage
• You want to get started in minutes without a learning curve

Final verdict

Promptwatch and Mentions.so serve different audiences. Mentions.so is a monitoring dashboard with a generous free tier -- good for small brands who want basic visibility tracking without spending money. Promptwatch is a full optimization platform that helps you find gaps, generate content, and actually improve your AI search rankings.

If you're serious about AI visibility and want to treat it like a real channel (not just a curiosity), Promptwatch is the better investment. The content generation alone justifies the price -- you're not just watching your competitors win, you're building the content to compete. The AI crawler logs, Reddit/YouTube tracking, and ChatGPT Shopping features are all things you can't get elsewhere.

Mentions.so's free tier is legitimately useful for testing the waters or for very small brands with limited budgets. But once you outgrow it, the jump to $249/mo without clear feature transparency makes the value proposition murky.

Bottom line: Promptwatch is the platform for brands that want to win in AI search. Mentions.so is the free tool for brands that want to watch.
