Head-to-head review · Updated June 2026
Gauge vs Topic: which one wins in 2026?
Gauge and Topic 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.
Topic is cheaper out the gate, but Gauge tracks more AI platforms. The right pick depends on which dimension matters most for you.
The verdict
Pick
Topic
Pick Topic if you want the cheaper option ($99/mo vs $100/mo).
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.

- 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 Topic
Founded by Ryo Chiba, Nikhil Aitharaju, based in Toronto, Canada. On their site they list 9 named customers including Magoosh, Quizlet, BiggerPockets, Amerisleep. Pricing starts at $99/mo.
Content optimization platform that turns research into briefs and outlines.
What people praise
- Cuts content research time 45-50% by auto-parsing the top 30 Google results for headings, questions, and keyword targets.

- Pricing changes infrequent and no free trial beyond the $7 intro pack.
- Acquired by CafeMedia/Raptive in September 2021; roadmap pace has slowed compared to standalone Surfer or Clearscope.

Feature parity
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
- Platform coverage matters. Gauge monitors 4 AI platforms; Topic covers 0.
- Streamlined UI focused only on AI visibility, no extra SEO bloat to navigate around
When Topic wins
- Budget is the constraint. Topic starts at $99/mo vs Gauge's $100/mo, so on a per-seat basis it's the cheaper way in.
- Cuts content research time 45-50% by auto-parsing the top 30 Google results for headings, questions, and keyword targets.
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.
Reasons to pick one over the other
Reasons to pick Gauge over Topic
- Broader AI platform coverage. Gauge tracks visibility across 4 AI engines vs Topic's 0.
- Wider integration ecosystem. Gauge integrates with 11 tools; Topic ships 3.
- What users praise most. Streamlined UI focused only on AI visibility, no extra SEO bloat to navigate around
Reasons to pick Topic over Gauge
- Lower entry price. Topic starts at $99/mo vs Gauge's $100/mo.
- More plan flexibility. Topic offers 4 pricing tiers vs Gauge's 3, so there's a better chance one fits your team size.
- What users praise most. Cuts content research time 45-50% by auto-parsing the top 30 Google results for headings, questions, and keyword targets.
Switching from one to the other
From Gauge to Topic
Export your saved queries and prompt panels from Gauge (most tools support CSV export). Most Topic setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Topic'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 Topic to Gauge
Same flow in reverse. Export from Topic, 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 Topicare 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 Topic?
Honestly: neither one fully solves the problem. Gauge and Topic 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 Topic 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 Topic cost?
Gauge starts at $100/mo. Topic starts at $99/mo. 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 Topic cover?
Gauge covers 4 AI platforms. Topic covers an undisclosed number of. 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 Topic actually improve your AI visibility, or just measure it?
Both Gauge and Topic 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 Topic?
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.
