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