Why it’s different Every other whiteboard was made for business decks and sticky notes. We built ours for the exact moment you need to test if your game mechanic actually works, before your session starts.

We’re actively developing & we listen New features ship every week, directly inspired by feedback from creators like you. You’re literally shaping PlaySesh as we grow.

Built by game creators Our team shipped games and products at major studios. We felt the pain of clunky prototyping tools, so we built the one we always wanted and we’re making it better every week based on how you use it.
