Head-to-head review · Updated June 2026

Gauge vs SISTRIX: which one wins in 2026?

An honest editorial comparison from the team at GrowthManager.ai. We make a competing product, which is disclosed in full at the bottom.

Gauge and SISTRIX 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. Gauge has raised $500K (pre-seed), SISTRIX has raised Bootstrapped; Both companies are roughly comparable in size; the choice comes down to price, coverage, and fit.

Gauge is cheaper out the gate, but that's not the only thing that matters. The right pick depends on which dimension matters most for you.

The verdict
★ Our pick
Pick

Gauge

Pick Gauge if you want the cheaper option ($100/mo vs $119/mo); and you need broader AI platform coverage (4 platforms vs 0).

Pick

SISTRIX

Pick SISTRIX if you want the cheaper option ($119/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.

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 SISTRIX

SISTRIX has raised Bootstrapped. Founded by Johannes Beus, based in Bonn, Germany. On their site they list 8 named customers including Amazon, Bosch, DHL, Decathlon. Pricing starts at $119/mo.

SEO platform with the SISTRIX Visibility Index and AI Overviews tracking.

What people praise

  • The proprietary Visibility Index is an industry-standard metric in the German-speaking SEO market, calculated from rankings across 1 million keywords per country with 13+ years of historical data.
  • Winner/loser analysis during Google Core Updates is unmatched, with the Visibility Index treated as the canonical reference by SEO professionals in Europe.
  • Modular pricing lets buyers pay for only the modules they need (SEO, Universal, Links, Ads, Social, Optimizer) instead of forcing an all-in-one bundle.
  • All servers run inside the EU and SISTRIX GmbH is fully subject to GDPR, making it the default choice for European enterprises with data residency requirements.

Where it falls short

  • Data depth is heavily skewed toward DACH (Germany, Austria, Switzerland) and Western Europe; US and APAC coverage is materially weaker than Ahrefs or Semrush.
  • Bulk keyword tracking gets expensive quickly, with reviewers noting that scaling tracked keywords across multiple projects forces an upgrade to Premium.
  • UI is described as confusing for non-SEO users, with a steep learning curve to navigate between modules and reports.
  • Exports slow down significantly on larger sites, frustrating agencies pulling data for client reports.

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.

Only on Gauge
  • Prompt Tracking. Monitors AI responses across platforms over time so brand presence is trended, not snapshot
  • Brand Coverage and Citation Rate. Measures what % of tracked answers mention the brand and what % cite the brand's website

  • Content Engine. Generates AI-optimized articles tuned for both AI search and traditional search
  • Ask Gauge. Agentic AI assistant that recommends and executes visibility improvements
  • ChatGPT Ads Tracker. Monitors ad performance inside ChatGPT
Only on SISTRIX
  • Visibility Index. Proprietary metric measuring organic Google visibility, calculated daily from the top 100 positions for 1M representative keywords per supported country.

  • Links Module. Backlink profile audit and link gap analysis against competitors.
  • Optimizer. On-page audit tool that crawls websites and flags technical SEO issues.
  • Ads Module. Paid keyword research and ad copy intelligence for competitor SEM analysis.
  • SISTRIX for Amazon. Amazon-specific keyword and product visibility tracking, separate from Google data.

When each one wins

When Gauge wins
  • Budget is the constraint. Gauge starts at $100/mo vs SISTRIX's $119/mo, so on a per-seat basis it's the cheaper way in.
  • Platform coverage matters. Gauge monitors 4 AI platforms; SISTRIX covers 0.
  • Streamlined UI focused only on AI visibility, no extra SEO bloat to navigate around
When SISTRIX wins
  • The proprietary Visibility Index is an industry-standard metric in the German-speaking SEO market, calculated from rankings across 1 million keywords per country with 13+ years of historical data.
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 SISTRIX

  1. Lower entry price. Gauge starts at $100/mo vs SISTRIX's $119/mo.
  2. Broader AI platform coverage. Gauge tracks visibility across 4 AI engines vs SISTRIX's 0.
  3. Built for the LLM era. Gauge was founded in 2024, built around AI search from day one; SISTRIX dates back to 2008 and is retrofitting.
  4. What users praise most. Streamlined UI focused only on AI visibility, no extra SEO bloat to navigate around

Reasons to pick SISTRIX over Gauge

  1. More plan flexibility. SISTRIX offers 4 pricing tiers vs Gauge's 3, so there's a better chance one fits your team size.
  2. More verified reviews. SISTRIX has 20 G2 reviews vs Gauge's none on file, so the average rating carries more weight.
  3. Faster product velocity. SISTRIX has shipped 5 public launches in the last year vs Gauge's 0.
  4. More mature platform. SISTRIX (founded 2008) has had more time to harden the product than Gauge (2024).
  5. What users praise most. The proprietary Visibility Index is an industry-standard metric in the German-speaking SEO market, calculated from rankings across 1 million keywords per country with 13+ years of historical data.

Switching from one to the other

From Gauge to SISTRIX

Export your saved queries and prompt panels from Gauge (most tools support CSV export). Most SISTRIX setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate SISTRIX'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 SISTRIX to Gauge

Same flow in reverse. Export from SISTRIX, 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 SISTRIXare 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 SISTRIX?

Honestly: neither one fully solves the problem. Gauge and SISTRIX 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 SISTRIX cost?

Gauge starts at $100/mo. SISTRIX starts at $119/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 SISTRIX cover?

Gauge covers 4 AI platforms. SISTRIX 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 SISTRIX actually improve your AI visibility, or just measure it?

Both Gauge and SISTRIX 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 SISTRIX?

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.
