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.
