Mentions.so vs Promptwatch (2026): Which AI visibility tool is better?

Key Takeaways

• Promptwatch is the more complete platform -- it tracks visibility, analyzes content gaps, generates optimized articles, and monitors AI crawler behavior. Mentions.so focuses purely on tracking mentions and sentiment.
• Mentions.so has a free tier ($0/mo for basic tracking), while Promptwatch starts at $99/mo but includes actionable optimization tools from day one.
• Content generation is Promptwatch-only -- its AI writing agent creates articles engineered to get cited by ChatGPT and Claude, grounded in 880M+ citation data points. Mentions.so doesn't help you create content.
• Crawler logs are a Promptwatch exclusive -- see exactly when ChatGPT, Claude, and Perplexity crawl your site, which pages they read, and errors they encounter. Critical for diagnosing indexing issues.
• Mentions.so is simpler and cheaper for pure monitoring -- if you just want to track mentions and sentiment without optimization features, it's a solid budget option.
• Promptwatch closes the loop -- find gaps, generate content, track results. Most competitors (including Mentions.so) stop at step one.

Overview

Mentions.so

Mentions.so launched as a straightforward brand mention tracker for AI search engines. It monitors how ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek, and Meta AI talk about your brand across custom prompts. The platform emphasizes sentiment analysis -- showing whether AI responses are positive, neutral, or negative toward your brand -- and competitor comparison dashboards. You can track AI-driven traffic with their analytics snippet and get daily performance reports.

The core value: know what AI says about you and how you stack up against competitors. Mentions.so positions itself as an accessible entry point for brands new to AI visibility tracking, with a free tier and pricing that starts lower than most competitors.

Promptwatch

Promptwatch is the market-leading AI Search Visibility and Generative Engine Optimization (GEO) platform, used by 7,000+ brands including Booking.com, Center Parcs, and Typeform. It tracks visibility across 10 AI models (ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews, Grok, DeepSeek, Meta AI, Mistral, Copilot) but goes further than monitoring -- it helps you fix visibility gaps.

The platform analyzes 880M+ citations to show exactly which prompts competitors rank for but you don't, then generates content engineered to get cited by AI models. You also get AI crawler logs (real-time tracking of when ChatGPT, Claude, etc. hit your site), Reddit and YouTube citation tracking, ChatGPT Shopping monitoring, prompt volume estimates, and page-level citation tracking. The goal isn't just to see where you're invisible -- it's to close the gap with actionable content and optimization.

Side-by-Side Comparison

Head-to-head feature deep-dive

AI model coverage

Mentions.so tracks 7 major AI platforms: ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek, and Meta AI. That covers the mainstream models most brands care about. The interface shows side-by-side responses from each model for your tracked prompts, making it easy to compare how different AIs talk about your brand.

Promptwatch monitors 10 models -- the same 7 plus Google AI Overviews (the AI snippets in Google search results), Google AI Mode (conversational search), Mistral, and Copilot. The Google coverage is significant because AI Overviews appear in billions of searches daily. Promptwatch also tracks ChatGPT Shopping (product recommendations in ChatGPT), which Mentions.so doesn't cover.

Verdict: Promptwatch has broader coverage, especially for Google's AI features and shopping recommendations. If you only care about conversational AI models, Mentions.so's 7-model lineup is sufficient.

Tracking and monitoring capabilities

Both platforms let you define custom prompts and track how AI models respond. Mentions.so shows you the full AI response for each prompt, highlights your brand mentions, and tracks sentiment (positive, neutral, negative) over time. You get daily performance reports and can compare your visibility to competitors on a shared dashboard.

Promptwatch does all that but adds layers of depth. You see not just whether you're mentioned, but which specific pages AI models cite, how often, and in what context. The platform breaks down citation sources into categories: corporate (your own site), organic (third-party articles), news, Reddit threads, and YouTube videos. You also get prompt volume estimates (how many people are asking this question) and difficulty scores (how hard it is to rank), so you can prioritize high-value, winnable prompts instead of guessing.

The Answer Gap Analysis feature is a game-changer: it shows exactly which prompts competitors are visible for but you're not, then tells you what content you're missing. Mentions.so doesn't have an equivalent -- you can see competitor visibility, but you're on your own to figure out why they're winning.

Verdict: Promptwatch gives you more actionable data. Mentions.so tells you what's happening; Promptwatch tells you what to do about it.

Content optimization and generation

Mentions.so doesn't help you create or optimize content. It's purely a monitoring tool. You track mentions, analyze sentiment, compare competitors, and get insights -- but the actual work of improving your visibility happens outside the platform.

Promptwatch has a built-in AI writing agent that generates articles, listicles, and comparison pages grounded in real citation data. The content is engineered to get cited by AI models -- it's not generic SEO filler. The agent analyzes 880M+ citations to understand what AI models want to see, then creates content that fills the gaps in your site. You can generate 5-30 articles per month depending on your plan, and the content is optimized for specific prompts, personas, and competitor analysis.

This is the core difference between a monitoring tool and an optimization platform. Promptwatch closes the loop: find gaps, generate content, track results. Mentions.so stops at step one.

Verdict: If you need help creating content that ranks in AI search, Promptwatch is the only option. Mentions.so assumes you'll handle content creation elsewhere.

AI crawler logs and indexing insights

Mentions.so doesn't track AI crawlers. You see the output (AI responses) but not the input (whether AI models are actually reading your site, which pages they access, how often they return).

Promptwatch includes real-time AI crawler logs for ChatGPT, Claude, Perplexity, and other models. You see exactly when they hit your site, which pages they read, HTTP status codes, errors they encounter, and how often they return. This is critical for diagnosing indexing issues -- if AI models aren't citing your content, the logs show whether they're even seeing it. You can also identify pages that AI models read frequently but don't cite, which signals content quality or relevance issues.

No other AI visibility tool (including Mentions.so, Otterly.AI, Peec.ai, AthenaHQ) offers crawler logs at this level of detail.

Verdict: Promptwatch wins decisively. Crawler logs are essential for understanding why you're not getting cited, and Mentions.so doesn't have them.

Competitor analysis

Mentions.so shows competitor visibility in a side-by-side dashboard. You can see how often competitors are mentioned for the same prompts, compare sentiment, and track changes over time. It's a clean, visual way to benchmark your performance.

Promptwatch offers competitor heatmaps that show who's winning for each prompt across all LLMs. You see not just whether a competitor is mentioned, but which specific pages they're getting cited from, what content angles they're using, and how their visibility changes over time. The Answer Gap Analysis also highlights prompts where competitors dominate but you're invisible, then suggests content topics to close the gap.

Both platforms handle competitor tracking well, but Promptwatch gives you more granular data and actionable next steps.

Verdict: Tie for basic competitor tracking. Promptwatch pulls ahead if you want to understand why competitors are winning and how to catch up.

Traffic attribution and analytics

Mentions.so includes an analytics snippet you can add to your site to track AI-driven traffic. The dashboard shows how much traffic you're getting from AI models and which prompts are driving visits. It's straightforward and works.

Promptwatch offers three methods for traffic attribution: a JavaScript snippet (like Mentions.so), Google Search Console integration (for AI Overviews traffic), and server log analysis (for deeper insights). You can see which specific pages are driving traffic, which AI models are sending visitors, and how that traffic converts. The page-level tracking connects visibility to revenue, so you're not just optimizing for mentions -- you're optimizing for business outcomes.

Verdict: Promptwatch has more robust attribution options, especially for connecting visibility to conversions. Mentions.so's snippet works fine for basic traffic tracking.

Pricing and value

Mentions.so has a free tier (details not fully specified on their site, but they advertise "$0/month" for basic tracking). Paid plans start at $99/mo (Starter) and go up to $599/mo (Agency). Annual billing saves 16%. The Starter plan likely includes limited prompts and basic features, while higher tiers add more prompts, team seats, and advanced analytics.

Promptwatch starts at $99/mo (Essential: 1 site, 50 prompts, 5 AI-generated articles). Professional is $249/mo (2 sites, 150 prompts, 15 articles, crawler logs, state/city tracking). Business is $579/mo (5 sites, 350 prompts, 30 articles). Annual billing saves 25%. All plans include the full feature set -- tracking, gap analysis, content generation, crawler logs, Reddit/YouTube tracking, ChatGPT Shopping, and traffic attribution. The main differences are scale (sites, prompts, articles).

At the $99/mo entry point, Promptwatch gives you significantly more functionality than Mentions.so's Starter plan. You're not just tracking mentions -- you're getting content gap analysis, AI-generated articles, and crawler logs. Mentions.so's free tier is appealing if you're on a tight budget and only need basic monitoring, but you'll quickly hit limits.

Verdict: Promptwatch offers better value at every price point if you need optimization tools. Mentions.so is cheaper if you only want monitoring and have a very limited budget.

Who should pick which tool

Choose Mentions.so if:

• You're on a tight budget and need a free or low-cost monitoring tool
• You only want to track brand mentions and sentiment across AI models
• You have a content team that handles optimization separately and just needs visibility data
• You're new to AI visibility tracking and want a simple, focused interface
• You don't need crawler logs, content generation, or deep citation analysis

Choose Promptwatch if:

• You want to actively improve your AI visibility, not just monitor it
• You need content gap analysis to understand why competitors are winning
• You want AI-generated articles engineered to get cited by ChatGPT and Claude
• You need to diagnose indexing issues with AI crawler logs
• You care about Reddit, YouTube, and ChatGPT Shopping citations
• You want to connect visibility to traffic and revenue with page-level tracking
• You're serious about AI search as a revenue channel and need a complete optimization platform

If you're also exploring how to improve your overall AI search presence beyond just brand mentions, Promptwatch is worth a closer look -- it's built around the action loop of finding gaps, generating content, and tracking results, which most monitoring-only tools skip entirely.

Final verdict

Promptwatch is the better choice for most brands. It does everything Mentions.so does (tracking, sentiment, competitor comparison) plus content gap analysis, AI-generated articles, crawler logs, Reddit/YouTube tracking, and prompt intelligence. At $99/mo, the Essential plan gives you a complete optimization platform, not just a monitoring dashboard. You're not left wondering what to do next -- the platform tells you which content to create and helps you create it.

Mentions.so makes sense if you're on a very tight budget and only need basic mention tracking. The free tier is a real advantage for startups or solopreneurs who can't justify $99/mo yet. But once you're ready to actually improve your AI visibility (not just watch it), you'll need to layer on other tools or manual work -- at which point Promptwatch's all-in-one approach becomes more cost-effective.

The deciding factor: do you want to monitor or optimize? If you just want to know what AI says about you, Mentions.so works. If you want to shape what AI says and drive traffic from it, Promptwatch is the only platform that closes the loop.
