Scribble Together vs Whimsical

Scribble Together is an online whiteboard for handwriting equations, drawing diagrams and annotating PDFs. Users can import PDF files, add marks and export the annotated documents. Boards provide an infinite canvas, and users can create unlimited whiteboards. Owners can allow guests to scribble and navigate on a shared board; guests join by link or temporary four-digit code without registration or passwords. Background choices include graph, lined, dot-grid and music staff paper. A Zoom app gives meeting participants access to whiteboards created in the meeting. The help guide describes PDF import and export through Google Drive using the iOS file picker and PDF export feature. Its Free plan provides an offline personal notebook for iOS, unlimited whiteboards and guest joining. The Member plan costs $4.16 a month and includes web board creation, access across devices and unlimited guests. First-time web sign-ins receive a three-day trial; memberships include 14 or 30 free days depending on monthly or annual membership. The project began in 2017.

Whimsical is a collaborative whiteboard for product builders, with tools for diagrams, wireframes, flowcharts, mind maps, and planning on an infinite canvas.
