Overview

Mentions.so

Mentions.so launched as a dedicated AI brand tracking platform in 2024. It monitors how your brand appears across major AI models -- ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek, Meta AI, and Google AI Overview. The platform tracks mentions, analyzes sentiment, compares you to competitors, and provides recommendations for improving your AI visibility. It includes AI traffic attribution so you can see how much traffic comes from AI search results.

The tool is built around custom prompts. You can use AI-suggested prompts or write your own to monitor specific queries relevant to your business. Daily reports show where you're mentioned, where you're missing, and what to do about it.

Ahrefs Brand Radar

Ahrefs Brand Radar is a feature within the larger Ahrefs SEO platform, announced in late 2024. It tracks brand mentions across AI-powered search engines and traditional search results. The tool uses a fixed set of prompts to check how often your brand appears compared to competitors.

Brand Radar is not a standalone product -- you need an Ahrefs subscription to access it. That subscription includes all of Ahrefs' other tools: Site Explorer, Keywords Explorer, Site Audit, Rank Tracker, and Content Explorer. If you're already paying for Ahrefs, Brand Radar is a nice bonus. If you only want AI brand tracking, you're paying for a lot of features you might not use.

Side-by-Side Comparison

AI model coverage

Mentions.so explicitly tracks 8 AI models: ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), Perplexity AI, Grok (X/Twitter), DeepSeek, Meta AI, and Google AI Overview. That's comprehensive coverage of the models people actually use for search and research in 2026.

Ahrefs Brand Radar tracks "AI-powered search engines" but doesn't publish a full list. Based on their announcements and user reports, it covers ChatGPT, Google AI Overview, and a few others -- but the exact lineup is unclear. The lack of transparency here is frustrating if you need to know whether a specific model is monitored.

Verdict: Mentions.so wins on breadth and clarity. You know exactly which models you're tracking.

Custom prompts vs fixed prompts

This is the biggest functional difference between the two tools.

Mentions.so lets you add unlimited custom prompts. You can monitor any query that matters to your business -- "best CRM for small teams", "top project management tools for agencies", "how to choose a membership platform". The tool also suggests prompts using AI based on your domain and industry, which speeds up setup.

Ahrefs Brand Radar uses a fixed set of prompts. You don't control what gets tracked. Ahrefs decides which queries to monitor, presumably based on search volume and relevance. This works if their prompts align with your business, but it's limiting if you have niche use cases or want to track specific competitor comparisons.

Verdict: Mentions.so is more flexible. Custom prompts let you track what actually matters instead of hoping Ahrefs' fixed set covers it.

Sentiment analysis and insights

Mentions.so tracks sentiment for each mention -- positive, neutral, or negative. You can see trends over time and understand how AI models frame your brand. The platform also provides daily recommendations: "Add more case studies to your pricing page", "Competitors are mentioned for feature X -- consider highlighting it". These insights are specific and actionable.

Ahrefs Brand Radar shows whether you're mentioned and how often, but sentiment tracking is basic. The tool doesn't provide optimization recommendations -- it's a monitoring dashboard, not a coaching tool.

Verdict: Mentions.so gives you more context and tells you what to do next. Ahrefs shows you the data and leaves you to figure out the rest.

Traffic attribution

Mentions.so includes AI traffic attribution. You add a tracking snippet to your site (or integrate with Google Search Console), and the platform shows how much traffic comes from AI models. You can see which prompts drive clicks and which pages AI users land on.

Ahrefs Brand Radar does not track traffic. It monitors mentions in AI responses, but you won't know if those mentions translate to actual visitors.

Verdict: Mentions.so closes the loop. You can connect visibility to traffic and traffic to conversions.

Competitor tracking

Both tools let you compare your brand to competitors.

Mentions.so shows side-by-side visibility scores for each competitor across all tracked AI models. You can see who's winning for specific prompts and track changes over time. The interface is clean and the data updates daily.

Ahrefs Brand Radar also tracks competitors and shows comparative mention rates. The data integrates with Ahrefs' broader competitive analysis tools, so if you're already using Ahrefs for SEO competitor research, this fits naturally into your workflow.

Verdict: Tie. Both tools handle competitor tracking well. Mentions.so is more visual, Ahrefs integrates with its existing ecosystem.

Ease of use

Mentions.so is straightforward. Add your domain, pick or create prompts, add competitors, done. The dashboard is focused entirely on AI brand tracking, so there's no clutter. Daily email reports keep you updated without needing to log in constantly.

Ahrefs Brand Radar lives inside the Ahrefs platform, which is powerful but dense. If you're new to Ahrefs, the learning curve is steep -- Brand Radar is just one feature among dozens. If you already use Ahrefs, adding Brand Radar to your workflow is easy.

Verdict: Mentions.so is simpler for newcomers. Ahrefs is easier if you're already an Ahrefs user.

Pricing comparison

Mentions.so is cheaper if you only want AI brand tracking. The $99/mo Starter plan covers one workspace with custom prompts and full model coverage.

Ahrefs is more expensive but includes the entire Ahrefs SEO suite. If you need keyword research, backlink analysis, site audits, and rank tracking on top of AI brand monitoring, Ahrefs is a better value. If you only care about AI mentions, you're overpaying.

Verdict: Mentions.so wins on price for dedicated AI tracking. Ahrefs wins on value if you need a full SEO platform.

What each tool is missing

Neither Mentions.so nor Ahrefs Brand Radar helps you fix the underlying problem: why aren't you being mentioned?

Both tools show you where you're invisible, but they don't tell you what content is missing or help you create it. You're left to guess what AI models want to see on your site.

If you're serious about improving your AI visibility -- not just tracking it -- tools like Promptwatch fill that gap. Promptwatch combines monitoring with content gap analysis and an AI writing agent that generates articles optimized for AI citations. It also tracks AI crawler logs so you know if models are even reading your site in the first place.

Mentions.so and Ahrefs Brand Radar are monitoring dashboards. Promptwatch is an optimization platform. Different use cases.

Who should pick which tool

Pick Mentions.so if:

• You want a dedicated AI brand tracking tool without paying for a full SEO suite
• Custom prompts matter -- you need to track specific queries relevant to your niche
• You want sentiment analysis and daily recommendations on how to improve
• Traffic attribution is important -- you need to connect AI mentions to actual site visitors
• You're starting fresh and don't already use Ahrefs
• Budget is tight and you want a free tier to test before committing

Pick Ahrefs Brand Radar if:

• You already pay for Ahrefs and want to add AI brand tracking as a bonus feature
• You're comfortable with a fixed prompt set and don't need custom queries
• You value integration with Ahrefs' broader SEO and competitive analysis tools
• You're more interested in monitoring than optimization
• Brand reputation and established tooling matter to your team

Consider Promptwatch if:

• You want to go beyond monitoring and actually improve your AI visibility
• Content gap analysis matters -- you need to know what's missing from your site
• You want AI crawler logs to see if models are even reading your pages
• Built-in content generation would help you create articles optimized for AI citations
• You're tracking AI visibility as part of a broader SEO and content strategy

Final verdict

Mentions.so is the better standalone AI brand tracking tool. It's cheaper, more flexible, and provides actionable insights instead of just data. Custom prompts, sentiment analysis, and traffic attribution make it a complete monitoring solution.

Ahrefs Brand Radar makes sense if you're already an Ahrefs customer and want basic AI mention tracking as an add-on. It's not worth subscribing to Ahrefs just for Brand Radar -- the fixed prompt set and lack of optimization features limit its usefulness as a standalone tool.

For most teams focused on AI visibility, Mentions.so is the smarter pick. For teams already invested in the Ahrefs ecosystem, Brand Radar is a nice bonus but not a reason to switch.
