Otterly.AI is one of the most affordable AI-search monitoring tools (from around $29/month) — it tracks how your brand appears in ChatGPT, Perplexity and Google AI Overviews. It's a good lightweight monitor. Here's how it compares to running a free check + one-time report instead.
Otterly (~$29/mo): ongoing prompt monitoring, link & brand mention tracking, alerts. Subscription pricing scales with prompts monitored.
AI Visibility Checker (free + $49 one-time): free 30-second check of whether AI names your brand; the $49 Full Report adds 8 buyer-question tests, competitor share-of-voice, a full GEO site audit with prioritized fixes, an Agent-Readiness score, and a 30/60/90-day action plan. No recurring charge.
Monitors tell you what is happening over time. The report tells you why you're invisible and exactly what to change — entity clarity, citable facts, schema, AI-crawler access. Most brands need the diagnosis once, then a monitor only if AI visibility becomes a tracked KPI.
