Automated customer feedback analytics that reveals why customers feel what they feel
ClientZen aggregates, cleans and applies consistent semantic tags to every piece of customer feedback automatically, so tagging stays uniform at scale.
Surface contact reasons, recurring issues, main questions, top feature requests and the real drivers of negative sentiment from one dashboard.
Mantra AI answers specific customer experience questions using your own feedback and context, so ad-hoc research becomes as simple as asking.
Track feedback trends, detect anomalies such as feedback spikes, and get personalized notifications before issues escalate.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
