Peec AI vs Otterly.AI vs Gauge: Which AI Visibility Tracker Wins in 2026?
A three-way breakdown of Peec AI, Otterly.AI, and Gauge on engine coverage, pricing, evidence quality, and who each platform actually fits in 2026.
Put Peec AI, Otterly.AI, and Gauge side by side and the differences show up fast: same category, same basic premise (track how AI engines talk about your brand), but different engine lists, different evidence standards, and a price range wide enough that "which one" is really "which one for your budget." Budget is usually the first filter here, Otterly.AI opens at $29/mo, Gauge at $599/mo, but the bigger differentiator once you dig in is what each platform does with the data after it's collected.
Peec AI is an excellent tracker with an earned reputation, as long as you budget for model add-ons rather than the sticker price. Otterly.AI is the best first tool to prove GEO matters, as long as you read past the sticker before scaling on it. Gauge is the raw-volume value play, but the bet is on an unreviewed, thinly-funded vendor rather than the product itself.

Where Peec AI wins
Peec AI's case rests on the most polished tracking UX in the category, a screenshot-backed audit trail on every data point, unlimited seats, and daily refreshes that agencies build client reporting around. $10M ARR in about 16 months, $29M raised, and a 4.9/5 average on G2. The trade-off: the sticker price only covers 3 models per tier, so realistic coverage runs 30 to 50% above list, and there's no historical backfill or action layer.
Where Otterly.AI wins
Otterly.AI's case rests on the fastest, cheapest on-ramp into GEO, a genuine no-card free trial, a working dashboard inside an hour, and a $29/mo entry point nothing else in this list undercuts. A Gartner Cool Vendor pick (2025) with a large SMB user base, though no G2 score is on record in our data. The trade-off: the advertised engine list is really 4 base engines (Gemini, Claude, and AI Mode are paid add-ons), and monitoring data can lag up to 7 days.
Where Gauge wins
Gauge's case rests on unmatched raw volume, 600 prompts run daily across six engines, roughly 108,000 answers a month, plus a content engine that ships 18 articles a month in the same subscription. Zero reviews on G2, Capterra, TrustRadius, or Trustpilot, and only about $500K raised (YC S24) versus rivals' eight-figure war chests. The trade-off: there are zero third-party reviews anywhere, the $99 starter tier was quietly removed mid-2026, and the company has raised a fraction of what its rivals have.
Action layer: who does something with the data?
Gauge is the only one of the three that acts on the data, via a content engine that ships 18 articles/mo plus nightly content-health audits. Peec AI and Otterly.AI stay deliberately monitoring-only. If someone on your team is ready to act on findings without a separate tool, weight that over raw tracking depth.
Pricing: sticker price vs configured price
Sticker prices rarely survive contact with a real configuration. Peec AI: $95/mo Starter (50 prompts, 3 models only, extra models cost $35 to $165/mo each), Agency from $245/mo, Enterprise custom for Claude/DeepSeek. Otterly.AI: $29/mo Lite (15 prompts, 4 base engines), $189/mo Standard (100 prompts, API), $489/mo Premium (400 prompts); Gemini, Claude, and AI Mode are $9 to $149/mo add-ons. Gauge: 1-week free trial, then $599/mo Growth (600 prompts/day across 6 engines, 18 articles/mo); Enterprise custom for Claude, Grok, and API. Price your actual engine list, prompt volume, and seat count against each of these before treating any single number as the real cost of ownership.
Who should pick which
- Pick Peec AI if you're a marketing team or agency that wants the category's cleanest tracking dashboard and will price out model add-ons before signing.
- Pick Otterly.AI if you're an SMB or first-time GEO buyer that wants the cheapest credible entry point and can live with weekly-ish data.
- Pick Gauge if you're a team that wants maximum daily answer volume plus content production in one tool, and accepts the vendor risk.
FAQ
Which of the three is cheapest for a small team?
Otterly.AI has the lowest entry price at $29/mo, and that tier includes 15 prompts, 4 base engines, 1 workspace. Gauge's $599/mo entry point buys considerably more out of the gate, so "cheapest" and "best value" aren't always the same tool.
Which one has the most trustworthy data?
Peec AI has the strongest independent review signal of the three: $10M ARR in about 16 months, $29M raised, and a 4.9/5 average on G2. Otterly.AI: A Gartner Cool Vendor pick (2025) with a large SMB user base, though no G2 score is on record in our data. Gauge: Zero reviews on G2, Capterra, TrustRadius, or Trustpilot, and only about $500K raised (YC S24) versus rivals' eight-figure war chests. Treat every AI-tracking vendor's accuracy claims as directional rather than exact, and cross-check a sample of results manually before reporting them upward.
Do any of these three help me fix visibility gaps, or just report them?
Gauge (via a content engine that ships 18 articles/mo plus nightly content-health audits) does; Peec AI and Otterly.AI don't, they're deliberately monitoring-only.
Do I need all three, or should I pick one?
Running two overlapping trackers rarely earns its keep, pick the one whose category (tracking-only, action-oriented, or research-grade) matches how your team actually works, and revisit the others only if that gap becomes obvious.
