What is Otterly.ai?
Otterly.ai monitors brand mentions and citations across AI engines, with prompt research, GEO content audits (crawlability and AI-readiness), competitive benchmarking, an API and a Looker Studio connector. It markets to a broad audience — SMBs and solopreneurs through to enterprise — and its pricing is fully transparent, starting at $29/mo with unlimited seats.
Two caveats. The base plans include only four engines — Gemini, Claude and Google AI Mode are paid add-ons that inflate the real price — and the jump from the 15-prompt Lite plan to the $189/mo Standard plan is steep. It is built for ongoing subscription monitoring of a brand, not a per-location local-business audit, and the full product still requires signup (a few free standalone tools aside).
When Otterly.ai is the better fit
- You want the cheapest entry point for ongoing monitoring ($29/mo) with transparent pricing.
- You want GEO content/URL audits and a Looker Studio connector for reporting.
- You are an SMB or agency that wants continuous tracking rather than a one-off check.
When PromptRank is the better fit
- You want Claude and Grok included, not as paid add-ons on top of a four-engine base.
- You want an instant full audit with no signup, not a trial.
- You want city-anchored local-business prompts and a per-model knowledge test.
- You want a full report on the free tier, not a 15-prompt entry plan.
