Adobe Target is Adobe's testing and personalization solution within Adobe Experience Cloud, used to tailor web, mobile and app experiences at scale.

Unlike most tools in this category, Clarity has no paid tiers, session caps, or feature gates behind a paywall; every feature, including AI-generated session summaries powered by Microsoft Copilot, is available at no cost.
