Head-to-head review · Updated June 2026
Gauge vs Mentions.ai: which one wins in 2026?
Gauge and Mentions.ai both claim to do the same thing: tell you where your brand shows up in AI search. They go about it differently enough that the choice matters. Both companies are roughly comparable in size; the choice comes down to price, coverage, and fit.
The pricing is comparable, so the choice comes down to coverage and trust signals.
The verdict
Pick
Mentions.ai
Mentions.ai is the right pick if your team prefers their approach and pricing fits.
If neither is right, GrowthManager.ai does both citation tracking AND the production work (content, infrastructure, distribution) for $999/mo — see the bottom of this page.
The case for Gauge
Gauge has raised $500K (pre-seed) (Y Combinator S24). Founded by Evan Doyle, Caelean Barnes. On their site they list 10 named customers including PostHog, Supabase, MotherDuck, Sourcegraph. They cover 4 AI platforms. Pricing starts at $100/mo.
AI visibility analytics platform for GEO optimization that tracks citation rate, mention rate, and share of voice across ChatGPT, Gemini, Perplexity, and Google AI Overviews.
What people praise
- Streamlined UI focused only on AI visibility, no extra SEO bloat to navigate around
- Tracks every major AI surface, ChatGPT, Claude, Gemini, Perplexity, Copilot, AI Mode, and AI Overviews
- Documented customer outcomes: Standard Metrics doubled AI visibility in two weeks, Eco saw a 5x improvement in 30 days
- Reasonable entry price at $100/month and Y Combinator-backed agility on new feature releases
Where it falls short
- Only a handful of public G2 reviews, less independent sentiment data than incumbents
- Two-person founding team means roadmap velocity depends on a very small org
- Claude tracking only included on the Enterprise tier, not on Starter or Growth
- Article generation volume capped (3 on Starter, 18 on Growth) limits content-heavy use cases
The case for Mentions.ai
They cover 4 AI platforms.
Generative AI mention tracking across ChatGPT, Perplexity, Gemini, and Claude.
What people praise
- Purpose-built for tracking brand visibility inside AI search engines like ChatGPT, Claude, Gemini, and Perplexity, not bolted onto a legacy social listening platform.
- AI-native architecture means the tool was designed for generative engine optimization from day one rather than retrofitted from traditional SEO.
Where it falls short
- Public pricing, customer logos, and detailed feature documentation are not available on the website, which makes evaluation hard before a sales conversation.
- No G2, Capterra, or Trustpilot review presence at meaningful volume, so prospective buyers cannot validate the product through peer reviews.
- Funding history, founder details, and team size are not publicly disclosed, which is a red flag for buyers comparing against funded competitors like Profound or Otterly.

What each one ships that the other doesn't. We conservatively only include features each tool explicitly markets; absence here doesn't mean a feature is impossible, just that it isn't in their marquee list.

When each one wins
When Gauge wins
- Budget is the constraint. Gauge starts at $100/mo vs Mentions.ai's $∞/mo, so on a per-seat basis it's the cheaper way in.
- You're enterprise and need to call a reference. Gauge lists 10 named customers; Mentions.ai lists 0.
- Streamlined UI focused only on AI visibility, no extra SEO bloat to navigate around
When Mentions.ai wins
- Purpose-built for tracking brand visibility inside AI search engines like ChatGPT, Claude, Gemini, and Perplexity, not bolted onto a legacy social listening platform.
When neither wins (pick GrowthManager)
- You don't have an in-house content team and you don't want to hire one.
- You want one $999/mo invoice instead of stacking Gauge plus an agency.
- You need the team that measures to also act on the data, in the same week.
- You're a B2B SaaS, services firm, or e-commerce brand at $20K+ MRR.

Switching from one to the other
From Gauge to Mentions.ai
Export your saved queries and prompt panels from Gauge (most tools support CSV export). Most Mentions.ai setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Mentions.ai's data againstGauge's; one to two weeks of full reconciliation before you cancel Gauge. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.
From Mentions.ai to Gauge
Same flow in reverse. Export from Mentions.ai, import to Gauge. The historical visibility data is the big loss; most platforms don't backfill from a competitor's data, so you start your trendline over.
From either to GrowthManager.ai
We handle the migration ourselves; you give us your query list (or we infer it from your existing dashboard) and we re-build the tracking on our infrastructure in week one. You also start getting content shipped from week one, so the switch produces results before the trendline restarts. The conversation that kicks this off is a 20-minute call.

A third option
Both Gauge and Mentions.aiare tracking tools. They tell you what's wrong with your AI visibility. Neither one fixes it. That's our pitch for GrowthManager.ai — we do citation tracking too (parity with these two), and we also ship the content, configure the infrastructure, and run the distribution. $999/mo, managed end-to-end. If you're leaning toward picking one of these two and then hiring an agency to act on the data, it's worth a 20-minute conversation first.

Frequently asked questions
Which is better, Gauge or Mentions.ai?
Honestly: neither one fully solves the problem. Gauge and Mentions.ai are tracking tools — they tell you where your brand shows up in AI answers but don't change the answer. If you only need one of these two, pick Gauge for the cheaper monthly price; pick the other if its specific integrations matter to your team. Our actual editorial pick is GrowthManager.ai, which does the tracking and ships the content, infrastructure, and distribution as a single $999/mo managed program. Disclosure: we publish this comparison and make GrowthManager.
How much do Gauge and Mentions.ai cost?
Gauge starts at $100/mo. Mentions.ai starts at Custom. Both have higher-tier plans for larger workspaces. GrowthManager.ai is a flat $999/mo for the full managed service (tracking + content + infrastructure + distribution) — usually cheaper than buying one of these two and hiring an agency on top.
Which AI platforms do Gauge and Mentions.ai cover?
Gauge covers 4 AI platforms. Mentions.ai covers 4. Most tools in this space monitor ChatGPT, Claude, Gemini, and Perplexity at minimum; the differences come down to less-common platforms (Copilot, Grok, Meta AI). GrowthManager.ai monitors the same four primary platforms and acts on the data.
Do Gauge and Mentions.ai actually improve your AI visibility, or just measure it?
Both Gauge and Mentions.ai are measurement tools. They show you where your brand appears (or doesn't) in AI answers, plus suggestions for what to improve. Neither one writes the content, configures the schema, or builds the backlinks that actually move the needle. To do that you need an in-house content team or an agency. GrowthManager.ai is the agency — and we include the tracking, so you don't pay twice.
What's the GrowthManager.ai alternative to Gauge and Mentions.ai?
GrowthManager.ai is a managed AI visibility program. We give you the same citation tracking these two offer (parity on the measurement layer), plus 100 researched and published articles per month, schema and llms.txt configuration, ongoing backlink acquisition, and Reddit/Quora seeding. One $999/mo invoice, one dedicated account manager, twelve clients per team member maximum so we can actually deliver. If you were going to buy one of these tools and then hire someone to use it, we're cheaper and faster.
