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.

AI performance reviews grounded in your team's actual work
An in-Slack agent that runs check-ins, collects peer input, and drafts performance reviews from evidence it gathered during the quarter.
Agendas are assembled from the week's actual work, with space for the employee to add what is on their mind before the meeting.
Windy notices when two people finish something together and asks how it went, so feedback arrives in days rather than six months later.
Committee members get a bias-flagged pre-read and a rating grid where every placement can be traced back to supporting evidence.
