| NextEO | Otterly.AI | |
|---|---|---|
| Scope | One connected system: buyer-conversation testing, technical and E-E-A-T audits, Hallucination Guard, open-web reputation, competitor benchmarking, AutoFix and a ChatGPT Ads manager, with EO, a built-in AI strategist, tying it together. | Prompt tracking with visibility analytics, content audits and optimization recommendations across engines like ChatGPT, Google AI Overviews, Perplexity and Google Gemini. |
| Methodology | Persona-driven buyer conversations that never name your brand, measuring whether AI surfaces you unprompted, the way real buyers actually ask and refine. | Tracks the specific prompts you choose, with plan quotas for how many you can watch (15 to 400 prompts depending on tier). |
| Accuracy layer | Hallucination Guard surfaces where AI states something false about you, with the exact prompt and response, so you fix facts, not just sentiment. | Reports mentions, position and sentiment rather than auditing what AI states as fact about you. |
| From insight to outcome | Turns findings into a prioritized fix list, applies the safe ones to your site with AutoFix, and tracks the trend so you can watch it improve. | Recommendations you implement yourself, elsewhere. |
| Pricing model | Flat per-website plans that include testing, fixing, reputation and reporting together, with a 7-day free trial. | Self-serve from about $29 a month for a small prompt quota; larger quotas cost more. |
