The core difference: monitoring vs optimization
Otterly.ai is an AI visibility monitoring tool. You set up prompts, it queries ChatGPT, Perplexity, and Gemini, and tells you whether your brand appears in the answers. It's a tracking dashboard — valuable for ongoing measurement.
WriteSEO's GEO Checker is a content optimization tool. You paste a URL or text, and it analyzes the page against 7 GEO signals from Princeton research — telling you specifically what's making AI systems skip your content and exactly what to fix. It's a diagnostic tool with an action plan.
