Overview
Mentions.so

Mentions.so is a brand mention tracking platform focused on AI search engines. It monitors how ChatGPT, Claude, Gemini, Perplexity, and other AI models talk about your brand, tracks sentiment, and compares your visibility against competitors. The interface is clean and the setup is fast -- add your domain, pick some prompts, and start getting daily reports on where you show up.
The core value is visibility: you see exactly what AI says about you, how often you're mentioned, and whether the sentiment is positive or negative. Mentions.so positions itself as "AI SEO" -- helping brands get recognized by AI platforms. It's built for marketers who want to know their AI footprint without digging into complex optimization workflows.
Gauge
Gauge takes a different angle. It's not just tracking mentions -- it's built around improving them. The platform monitors the same AI engines (ChatGPT, Claude, Gemini, Perplexity, Copilot, AI Overviews) but adds layers of competitive intelligence, content gap analysis, and actionable recommendations. Gauge tells you what's missing from your site, why competitors are getting cited instead of you, and what to do about it.
The standout feature is the built-in content generation. Gauge doesn't just show you the gaps -- it writes articles to fill them, grounded in citation data and prompt analysis. You're not stuck with a dashboard full of problems and no solutions. The platform is aimed at teams that want to own their category in AI search, not just monitor it.
Side-by-Side Comparison
| Feature | Mentions.so | Gauge |

Monitoring capabilities
Both platforms cover the major AI engines that matter in 2026. Mentions.so explicitly lists ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek, Meta AI, and Google AI Overview. Gauge covers ChatGPT, Claude, Gemini, Perplexity, Copilot, AI Mode, and AI Overviews. The overlap is nearly complete -- you're not missing critical models with either choice.
Mentions.so emphasizes real-time tracking and daily performance reports. You get a dashboard that shows mention frequency, sentiment trends over time, and side-by-side competitor comparisons. The interface leans visual -- charts showing sentiment shifts, bar graphs comparing your visibility to competitors, and a feed of actual AI responses mentioning your brand.
Gauge takes a more analytical approach. It tracks the same data but layers on competitive intelligence -- which content is being cited, what's being left out, and where your competitors are winning. The focus is less on sentiment and more on citation patterns. Gauge wants you to understand why you're not being mentioned, not just that you're not.
Verdict: Mentions.so wins on simplicity and sentiment tracking. Gauge wins on depth and competitive context.
Content optimization and gap analysis
This is where the platforms diverge sharply.
Mentions.so doesn't do content optimization. It shows you the data -- here's what AI says about you, here's how often you're mentioned, here's the sentiment -- but stops there. You're expected to take that information and figure out what to do with it yourself. The platform gives "practical recommendations" according to its marketing copy, but the live site data doesn't detail what those look like or how actionable they are.
Gauge is built around closing the loop. It identifies content gaps by analyzing what competitors are getting cited for that you're not. Then it generates articles to fill those gaps -- 3 articles per month on the Starter plan, 18 on the Growth plan. The content is grounded in citation data and prompt analysis, not generic SEO filler. Gauge also provides onsite and offsite recommendations -- specific actions to improve your AI visibility.
This is the core difference. Mentions.so is a monitoring tool. Gauge is an optimization platform. If you just want to track your brand, Mentions.so is enough. If you want to actually improve your rankings in AI search, Gauge gives you the tools to do it.
Verdict: Gauge by a mile. The content generation and gap analysis are the reason to pick Gauge over a pure monitoring tool.
Pricing comparison
| Plan | Mentions.so | Gauge |
|---|---|---|
| Free tier | Yes (limited features) | Freemium (limited) |
| Starter | $99/mo (all models, basic tracking) | $99/mo (100 prompts, ChatGPT only, 3 articles) |
| Mid-tier | Not listed | $599/mo (600 prompts, all models, 18 articles) |
| Agency/Enterprise | $599/mo | Custom pricing |
| Annual discount | 16% | Not mentioned |
Mentions.so has a simpler pricing structure. The $99/mo Starter plan gives you access to all AI models, which is a strong value proposition. The $599/mo Agency plan presumably adds more prompts, users, or workspaces, but the exact details aren't clear from the live site data. Annual billing saves 16%.
Gauge's pricing is more tiered by capability. The $99/mo Starter plan only covers ChatGPT, which feels limiting in 2026 when Claude, Gemini, and Perplexity are just as important. You need the $599/mo Growth plan to monitor all models and get 18 articles per month. That's a big jump.
For pure monitoring across all models, Mentions.so is cheaper. For optimization with content generation, Gauge's $599/mo Growth plan is the real entry point -- and at that price, you're paying for the content creation and gap analysis, not just the tracking.
Verdict: Mentions.so wins on price for basic tracking. Gauge is more expensive but includes content generation that justifies the cost if you need it.
User interface and setup
Mentions.so emphasizes simplicity. The setup is three steps: add your workspace (domain), set up prompts (AI-suggested or manual), and start getting daily reports. The interface shown on their site is clean and visual -- charts, graphs, and a feed of AI responses. It's designed for marketers who want to check a dashboard and move on.
Gauge's interface isn't detailed in the live site data, but the positioning suggests a more complex tool. The "complete toolkit" language and the emphasis on competitive intelligence, gap analysis, and content generation imply more layers and settings. That's not a weakness -- it's a trade-off. More power means more complexity.
Both platforms offer daily reports and custom prompts. Both let you track competitors. The difference is what you do with that data once you have it.
Verdict: Mentions.so is likely easier to get started with. Gauge requires more setup but gives you more control.
Traffic attribution and analytics
Mentions.so explicitly mentions tracking AI traffic and showing where it's coming from. The live site data includes a section titled "Track AI Traffic and See What's Driving Results" -- you can see how much traffic you're getting from AI models and which prompts or mentions are driving it. This is valuable for connecting visibility to actual business outcomes.
Gauge doesn't emphasize traffic attribution in the live site data. The focus is on visibility, citations, and content optimization. It's possible the feature exists but isn't highlighted, or it's a gap in the platform.
Verdict: Mentions.so has a clearer story on traffic attribution. Gauge might have it but doesn't lead with it.
Competitor analysis
Both platforms track competitors, but the depth differs.
Mentions.so shows side-by-side visibility comparisons -- bar charts showing your mention rate vs competitors over time. You can see who's winning for specific prompts and track sentiment trends. It's straightforward and visual.
Gauge goes deeper. It analyzes what content competitors are getting cited for, identifies gaps where they're visible and you're not, and gives you a roadmap to close those gaps. The competitive intelligence is tied directly to action -- here's where they're beating you, here's what to do about it.
Verdict: Gauge's competitor analysis is more actionable. Mentions.so's is easier to scan.
