GeoSonar vs OtterlyAI
Claude coverage, content audit, free plan, and pricing: which should you choose?
OtterlyAI is one of the most complete AI search monitoring tools with integrated content audit, public case studies, and an entry plan at $29/month. But Claude is still listed as coming soon on OtterlyAI's pricing page, while GeoSonar includes Claude in its standard monitoring, adds a permanent free plan, and summarizes AI visibility with a 0-100 GEO Score.

Quick answer
GeoSonar
Choose GeoSonar if you need Claude monitoring included by default, a permanent free plan, a clear 0-100 GEO Score, and an Action Center that turns visibility gaps into prioritized work.
OtterlyAI
Choose OtterlyAI if you need content audits, content briefs, crawlability checks, GEO URL audits, and API/MCP access from a paid Standard plan.
Content audit vs GEO Score: two optimization philosophies
OtterlyAI is a Content Intelligence Platform: it goes beyond monitoring to offer content audits, crawlability checks, content briefs, and GEO URL audits to optimize existing content. Its public pricing page lists Lite at $29/month, Standard at $189/month, Premium at $489/month, and Google AI Mode plus Gemini as paid add-ons. GeoSonar starts from a different question: what is your GEO Score today and what do you need to do to improve it? The 0-100 score is deterministic and comparable over time. The Action Center turns every gap into prioritized tasks. And the free plan is permanent, no credit card needed. Most importantly, GeoSonar monitors Claude, while OtterlyAI lists Claude as coming soon.
Methodology
We compared public product and pricing pages, monitored engine coverage, plan prices, add-ons, API/MCP availability, content-audit claims, free-trial/free-plan wording, and case-study/social-proof claims. OtterlyAI's pricing page was treated as authoritative for current plan prices and feature availability.

Who should choose which?
GeoSonar
GeoSonar is the right choice if you want to monitor Claude (essential in many B2B sectors), start for free without a credit card, have a clear GEO Score 0-100, and an Action Center with prioritized tasks. It's designed for brands, SMBs, and marketing teams that want to start GEO optimization immediately.
OtterlyAI
OtterlyAI is the choice for teams that want a more complete content-side workflow: content audit, crawlability analysis, content briefs, and GEO URL audits for page-level optimization. It is also a fit if API/MCP access from the Standard plan is a requirement.
Our verdict
OtterlyAI is a strong content intelligence tool, with public case studies and advanced content-audit features. But its pricing page lists Claude as coming soon, the cheapest paid plan starts at $29/month, and API/MCP access starts from the Standard plan. GeoSonar monitors Claude, has a permanent free plan, and uses a deterministic GEO Score to synthesize AI visibility into one number. If Claude coverage or a no-cost starting point matters, GeoSonar is the better fit.
