Padlet Sandbox vs Scribble Together

Padlet Sandbox is a collaborative digital canvas for drawing, writing, and adding media. People can contribute together and see one another’s additions in real time. Add cards and play them in sequence as a slideshow for a lesson, presentation, or storybook, or connect card content to build branching activities, interactive documents, and games. The product page describes more than 25 tools, including breakout rooms, keyboard shortcuts, object linking, granular permissions, and automatic content moderation. Sandbox supports diagramming, workshop templates, guest collaboration, presentation mode, and voting, but it is not an infinite canvas. It runs on Android, iOS, macOS, Windows, and the web, with support for major browsers. Google options include sign-in, Classroom sharing, and Drive files; Padlet also supports importing Jamboards. The Free plan is free and includes 3 padlets, 20MB uploads, 1 user, 2-minute videos, and 5-minute audio. After June 30, 2026, free accounts are limited to 3 total Sandboxes and boards; additional Sandboxes become read-only unless the user upgrades.

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.
