The tools at a glance
Radarkit
AI brand monitoring across ChatGPT, Claude, Gemini, and Perplexity with API access
Radarkit monitors brand mentions and citations across 4 AI engines: 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. The 4-platform scope is the defining feature: teams that prioritise Claude and Gemini coverage alongside the two biggest first-party AI search engines often shortlist Radarkit.
Where Radarkit stands out is on price and API access. The Lite plan at $29/month is the lowest paid entry point in the AI visibility category for a tool that includes API access across all four paid tiers. The Growth tier at $79/month unlocks competitor benchmarking and citation source analysis, and the Pro tier at $139/month adds unlimited historical data. For developers and analysts building custom reporting stacks, this combination is the deciding factor in this AI visibility tool comparison.
The gaps to plan around are scope and delivery. Radarkit does not currently track Google AI Overviews or Google AI Mode, which matters for SEO teams whose audiences are asking questions in Google search. There is no white-label delivery or branded client view on any tier, so agencies delivering AI visibility reports to clients would need a separate reporting layer. For internal Generative Engine Optimization (GEO) tracking on a tight budget, Radarkit is a credible option.

Visiblie
AI search visibility tracker with GEO recommendations and alerts across 5 platforms
Visiblie monitors brand visibility across five AI platforms: ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews. It tracks where your brand appears in AI-generated answers, how sentiment around those mentions shifts over time, and how your performance compares to competitors. The Google AI Overviews inclusion is notable for SEO teams whose audiences ask questions in Google search.
The platform goes beyond monitoring by adding GEO (generative engine optimization) recommendations. Rather than just showing you that your visibility dropped, Visiblie tries to explain why and suggests specific content changes that could improve citation rates. This makes it more useful for content teams who want something actionable alongside the dashboard data. The recommendations point to specific topic areas or content formats that could close citation gaps.
Visiblie is a self-serve product aimed primarily at in-house marketing and SEO teams, priced in euros starting at €79/month on Starter and scaling to €199/month on Scale, with Enterprise on custom pricing. It does not offer API access or client-sharing features, which limits its utility for agencies. For teams that want a contained AI visibility workflow with alerts, scoring, and optimization hints all in one place, Visiblie covers that use case well.
