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.

Radarkit
AI brand monitoring across ChatGPT, Claude, Gemini, and Perplexity with API access
Radarkit monitors brand mentions and citations across ChatGPT, Claude, Gemini, and Perplexity. The platform tracks how often your brand appears in AI-generated answers, which sources the AI models cite, and how your visibility compares to competitors over time.
Where Radarkit stands out is its pricing accessibility. At $29/month for the Lite plan, it is one of the cheapest ways to get structured AI visibility data with API access included. Most tools at this price point are either read-only dashboards or restrict API use to higher tiers.
The platform is self-serve and does not require a sales call. You can sign up, connect your brand, and start seeing citation data within a day. The citation source identification feature is particularly useful: it tells you which websites and content pieces AI models are using when they mention your brand, giving you a starting point for content strategy decisions.
