The tools at a glance
AI Search Watcher
Free AI visibility monitoring for brand mentions across ChatGPT, Perplexity, Gemini, and Google AI
AI Search Watcher is a feature within the Mangools platform that monitors brand mentions across ChatGPT, Perplexity, Gemini, and Google AI Overviews. Mangools is best known for KWFinder, its keyword research tool, but the platform has expanded to cover AI search as a natural extension of its SEO product suite.
Access is included with existing Mangools subscriptions, which start at $15.60 per month on annual billing. This makes AI Search Watcher effectively free for the large number of SEO professionals already using Mangools for keyword research, SERP analysis, or backlink tracking. There is no separate subscription to manage and no additional cost to activate the feature.
The trade-off versus dedicated AI visibility platforms is feature depth. AI Search Watcher covers the essential monitoring workflow: track your brand, get alerted when it appears, see how you compare to competitors. What it does not provide is API access to pull that data into external tools, white-label views for client delivery, or the granular prompt-level tracking that dedicated platforms offer.

Otterly.AI
Track brand visibility across 7 AI engines from $29/month with API and MCP support
Otterly.AI is an AI search monitoring platform that tracks how and where your brand appears across ChatGPT, Google AI Overviews, Google AI Mode, Perplexity, Microsoft Copilot, Claude, and Gemini. It positions itself as a generative engine optimization (GEO) tool, meaning it goes beyond showing you where you appear and actively recommends changes to improve your citations.
The platform launched with one of the most competitive price points in the category. At $29/month for the Lite plan, you get real tracking across all 7 AI models, answer ranking monitoring, and citation link analysis. That is significantly cheaper than most dedicated AI visibility tools, which tend to start at $79 to $99/month for comparable coverage.
The tradeoff is that workflow integration requires the Standard plan at $189/month. The Lite plan gives you a solid monitoring dashboard but no API access and no MCP integration. Teams who want to pull data into their own tools or connect Otterly to an agent stack will need to upgrade.
