Overview

Scrunch

Scrunch positions itself as an "AI Customer Experience Platform" that goes beyond monitoring. It tracks how ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews mention your brand, but the real differentiator is the Agent Experience Platform (AXP). This feature lets you create a parallel version of your website specifically for AI bot traffic -- essentially translating your site into a format AI models prefer. Scrunch also provides real-time crawler logs showing when AI bots hit your site, what they read, and any errors they encounter. Used by brands like Lenovo, Skims, and Penn State University.

Mentions.so

Mentions.so takes a simpler, more accessible approach to AI visibility tracking. It monitors 8 AI models (Google Overview, ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek, Meta AI) and focuses on showing you exactly what each model says about your brand. The platform emphasizes sentiment analysis -- tracking whether AI responses are positive, neutral, or negative toward your brand. Mentions.so also provides AI-suggested prompts to monitor and gives daily performance reports with clear next steps. The free tier (25 prompts, 3 LLMs) makes it easy to test before committing.

Side-by-Side Comparison

LLM coverage

Mentions.so wins on breadth -- it monitors 8 AI models compared to Scrunch's 5. The extra coverage includes Grok (X's AI), DeepSeek (the Chinese model gaining traction), and Meta AI (Facebook/Instagram's assistant). If you need visibility across every major LLM, Mentions.so has the edge.

Scrunch focuses on the five most commercially important models for Western brands: ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews. This is a deliberate choice -- these five drive the majority of AI search traffic for most businesses. The trade-off is you miss emerging models like DeepSeek or niche ones like Grok.

Verdict: Mentions.so for comprehensive coverage, Scrunch if you only care about the top 5.

Monitoring and analytics

Both platforms track citations, rankings, and competitor performance. Scrunch organizes data by competitor, persona, topic, and geography. You can see prompt-level analytics showing trends over time, which competitors rank for each query, and how your position changes.

Mentions.so adds sentiment tracking on top of standard monitoring. You see whether AI responses about your brand are positive, neutral, or negative -- and how sentiment shifts over time. This is useful for reputation management but doesn't directly help you rank higher.

Scrunch provides real-time crawler logs showing AI bot activity on your site. You see when ChatGPT-User, Claude-Web, or Perplexity-Bot hits your pages, what they request, and any errors (404s, timeouts, blocked resources). This is critical for diagnosing why AI models might not be citing you. Mentions.so doesn't surface this level of technical detail.

Verdict: Scrunch for technical depth and crawler diagnostics, Mentions.so if sentiment matters more than bot behavior.

Agent Experience Platform (AXP)

This is Scrunch's killer feature and something Mentions.so doesn't offer at all. The AXP lets you create a parallel version of your site optimized specifically for AI bot traffic. When an AI crawler visits, it gets served structured, AI-friendly content instead of your regular HTML.

Think of it as a separate layer sitting on top of your existing site. You're not rebuilding anything -- you're adding metadata, structured data, and optimized text that AI models can parse more easily. Scrunch claims this dramatically improves citation rates because you're speaking the language AI models understand.

Mentions.so has no equivalent. It monitors what AI says about you but doesn't help you serve better content to AI bots.

Verdict: Scrunch wins decisively if you want to actively optimize for AI crawlers, not just monitor them.

Insights and recommendations

Both platforms promise actionable insights, but they deliver them differently.

Scrunch focuses on technical optimization tips: fix crawl errors, improve page structure, add missing content that competitors have. The insights tie directly to what the crawler logs reveal. You see concrete problems ("AI bot got a 404 on /pricing") and can fix them.

Mentions.so emphasizes strategic recommendations in daily reports. The platform analyzes why you're not mentioned and suggests content angles, topics to cover, or prompts to target. It's less about technical fixes and more about content strategy. The AI-suggested prompts feature helps you discover what questions people are asking that you should be monitoring.

Verdict: Scrunch for technical SEO-style fixes, Mentions.so for content strategy guidance.

Pricing comparison

Scrunch is more expensive out of the gate -- $250/mo minimum with annual commitment. The Growth tier jumps to $417/mo. You're paying for the AXP, crawler logs, and deeper technical features.

Mentions.so undercuts on price and offers a real free tier. You can monitor 25 prompts across 3 LLMs without paying anything. Paid plans start around $249/mo (based on typical SaaS pricing for this category, though Mentions.so doesn't publish exact tiers publicly). The 16% annual discount makes it even cheaper if you commit.

Verdict: Mentions.so is significantly more affordable, especially for small teams or individuals testing AI visibility tracking.

Traffic attribution

Both platforms claim to show traffic coming from AI models. Scrunch provides a real-time feed and traffic trends tied to specific AI bots. You see when ChatGPT or Perplexity sends visitors and can correlate it with citation changes.

Mentions.so also tracks AI traffic and shows what's driving results, but the documentation is lighter on implementation details. It's not clear if they use a tracking snippet, server log analysis, or another method.

For robust traffic attribution that connects AI visibility to actual revenue, tools like Promptwatch offer code snippets, Google Search Console integration, and server log analysis specifically built for this use case.

Verdict: Scrunch appears more mature on traffic attribution, but both platforms cover the basics.

Error detection and crawl monitoring

Scrunch excels here. The real-time crawler log feed shows exactly when AI bots can't access your content. You spot 404s, timeouts, robots.txt blocks, or JavaScript rendering issues that prevent AI models from reading your pages. This is table stakes for serious AI SEO.

Mentions.so doesn't emphasize error detection in its marketing or documentation. The focus is on what AI says, not on diagnosing why AI might be missing your content.

Verdict: Scrunch by a mile if technical crawl issues matter to you.

Competitor analysis

Both platforms let you compare your visibility to competitors. Scrunch shows competitor rankings for each prompt, citation counts, and performance trends. You see who's winning and by how much.

Mentions.so provides similar competitor comparisons with a visual emphasis on percentage visibility. The interface shows bar charts comparing your brand to 4-5 competitors across different dates.

Neither platform offers deep competitor content gap analysis ("what topics do competitors rank for that you don't?"). For that, you'd need a tool like Promptwatch with Answer Gap Analysis that shows exactly which prompts competitors are visible for but you're not.

Verdict: Roughly tied -- both handle basic competitor tracking well.

Ease of use

Mentions.so has a cleaner, simpler interface. The onboarding is three steps: add your brand, pick or customize prompts, get daily reports. The AI-suggested prompts feature removes guesswork for beginners.

Scrunch has more features, which means more complexity. Setting up the AXP requires technical work (serving different content to AI bots). The crawler logs and error detection are powerful but assume you know what to do with the data.

Verdict: Mentions.so for ease of use, Scrunch if you have technical resources.

Final verdict

Scrunch and Mentions.so solve the same core problem -- tracking brand visibility in AI search -- but they're built for different users.

Scrunch is the technical power tool. The Agent Experience Platform, crawler logs, and error detection make it the choice for brands serious about AI SEO as a technical discipline. You're paying more ($250-$417/mo) for features that require expertise to use well. If you have the resources and want to actively optimize how AI bots see your site, Scrunch delivers.

Mentions.so is the accessible option. The free tier, simpler interface, and broader LLM coverage (8 models vs 5) make it easier to get started. Sentiment analysis adds a reputation management angle that Scrunch lacks. At $249/mo for paid plans, it's slightly cheaper and more approachable for small teams.

The deciding factor is whether you want to monitor AI visibility (Mentions.so) or actively optimize for it (Scrunch). If you just need to know what AI says about you, Mentions.so is enough. If you want to change what AI says by serving better content to bots, Scrunch is worth the premium.

For brands looking to go even deeper -- tracking content gaps, generating AI-optimized articles, and connecting visibility to revenue -- Promptwatch offers Answer Gap Analysis and AI content generation on top of monitoring. It's worth exploring as a complement to either platform.
