The whiteboard is the canvas you reach for when talking through the diagram isn't enough — when the client needs to see their thoughts mapped out, or watch the window of tolerance widen as you draw it, or move sticky notes around until the formulation clicks. It opens from the Share Screen button in a session. Your client sees it in the same place they'd see a shared screen, so the experience is familiar from day one. When you want them to draw too, you flip Two-way ON and they can annotate without needing an account or an app. ## The basics A shared editable canvas inside the session, used the way you'd use a paper pad in-room. Share Screen → Whiteboard. What your client sees the moment you do. Pen, eraser, text, shapes, color, and how Apple Pencil pressure shows up. ## Drawing together + saving the result The Two-way toggle — what the client sees, what they can and can't do, how to wipe their marks before export. Six colors of Post-it for capturing thoughts, homework prompts, and affirmations. Copy to clipboard, save as PNG, or save a vector PDF for the chart. ## The 29 therapy presets Nine categories, what's in each one, and when to reach for a preset versus a blank canvas.
