Comparison
Bikma and Otterly both track brand visibility in AI search, but on different levels: Otterly is a self-serve tool with transparent pricing and a very cheap entry point; Bikma pairs the platform with a university-validated method and an analyst-backed service. The choice depends on budget and on how much method matters compared with low-cost simplicity.
Choose Otterly if you want to start with a minimal budget, transparent pricing and an in-depth self-serve GEO audit. Choose Bikma if you want a validated method, Sentiment and Fact Checking as dedicated dimensions, Gemini and the Google surfaces among the standard models and an analyst-backed service.
Otterly is a self-serve tool with transparent pricing and an entry point of $29 a month with unlimited seats. It offers an in-depth GEO Audit (from 1,000 to 10,000 URLs a month), AI Prompt Research, a Brand Visibility Index, citation analysis, ChatGPT Ads and coverage in more than 50 countries. It provides API, MCP, Looker and Agent Analytics from the Standard plans, with an Agency Partner programme that includes unlimited workspaces, pitches and white-label reports. Base coverage is on four core engines (ChatGPT, AI Overviews, Perplexity, Copilot), while Claude, Gemini and AI Mode are paid add-ons. Prices range from $29 (Lite) to $189 (Standard) and $489 (Premium), with custom Enterprise pricing.
Bikma brings a scientific method with the Prompt Probability Index, born of research with the University of Pisa and the University of Insubria. Sentiment and Fact Checking are dedicated dimensions, within a framework of five dimensions. AI Overviews is included from the Starter plan, AI Mode and Gemini from the Basic plan: they are standard models, not add-ons. The data is paired with a service that includes a report reviewed by an analyst, with EU data.
