Profound vs Otterly.AI vs Gauge: Which GEO Tool Wins in 2026?
A three-way breakdown of Profound, Otterly.AI, and Gauge on engine coverage, pricing, evidence quality, and who each platform actually fits in 2026.
Profound, Otterly.AI, and Gauge keep showing up in the same shortlist because they're all answering the same question, how does a brand actually appear across ChatGPT, Perplexity, Gemini, and the rest of the AI answer engines, but they answer it in genuinely different ways and at genuinely different prices. The price spread alone is worth noting before you read the feature lists: Otterly.AI starts at $29/mo while Gauge starts at $599/mo, and neither number tells the whole story once you configure real coverage.
Profound is the category's reference platform on paper, but the $99 sticker is bait, the real product lives in a sales-gated Enterprise tier. 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.

| Category | Enterprise GEO platform | AI visibility tracker | AI visibility tracker | Full-stack AI visibility / GEO platform |
| Engine coverage | Up to 10 engines on Enterprise; Starter is ChatGPT-only, Growth covers 3 | 4 base engines (ChatGPT, AI Overviews, Perplexity, Copilot); Gemini/Claude/AI Mode cost extra | 6 engines, 600 prompts run daily (~108,000 answers/mo), the highest volume in this list | 10+ engines incl. ChatGPT, Gemini, Claude, Perplexity, Copilot, Grok; daily refresh on paid plans |
| Evidence / trust signal | Directional citation sampling; G2 reviewers report gaps versus manual ChatGPT checks | Gartner Cool Vendor 2025, but users report data lagging up to 7 days | Visibility scored against Gauge-generated synthetic prompts, not logged user queries | Citation analytics (page, domain, Reddit, YouTube); live AI crawler logs begin on Professional at $245/mo; 4.7/5 on G2 |

Where Profound wins
Profound's case rests on unmatched engine depth (up to 10 on Enterprise, including Grok, Meta AI, and DeepSeek), a unique Prompt Volumes query-demand dataset, and Agents that turn findings into drafted content. G2 4.6/5, Winter 2026 category leader, $1B valuation after a Feb 2026 Series C. The trade-off: everything it's actually known for sits behind an unpublished Enterprise price reportedly running $2,000 to $5,000+/mo, and setup realistically takes one to three months.
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?
This is where the three genuinely split. Profound (Agents that draft and execute content) and Gauge (a content engine that ships 18 articles/mo plus nightly content-health audits) both go beyond pure measurement, while Otterly.AI stays 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. Profound: $99/mo Starter (ChatGPT only, 50 prompts), $399/mo Growth (3 engines, 100 prompts), Enterprise custom (reportedly $2,000 to $5,000+/mo) for the full 10-engine, Prompt Volumes, Agents stack. 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 Profound if you're an enterprise team with the budget and a dedicated analyst to run the deepest dataset in the category.
- 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?
Profound has the strongest independent review signal of the three: g2 4.6/5, Winter 2026 category leader, $1B valuation after a Feb 2026 Series C. 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?
Profound (via Agents that draft and execute content) and Gauge (via a content engine that ships 18 articles/mo plus nightly content-health audits) do; Otterly.AI doesn't, Otterly.AI is 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.
