A free K-16 interactive whiteboard. Here's how to get started:
Reading file…
PPTX and ODP imports extract text and images only — for full slide fidelity, export your deck to PDF and import that.
DrawSplatTM is a free, open-source K–16 whiteboard for teaching, learning, and visual thinking. Draw, annotate images, add sticky notes, record audio and video notes, build diagrams, and organize your work into pages.
Save editable boards on your device and export PNG or PDF. Connect Google Drive for personal storage, or use a district-hosted MariaDB/MySQL service for account-based saving, classrooms, assignments, and student turn-ins. Districts can manage school Google sign-in and import class rosters.
Self-host DrawSplat and SplatWorks with Docker or a native installation. Start with the district installation guide, or open the Teacher Quick Start.
DrawSplat is licensed under AGPL-3.0-or-later; SplatWorks apps use GPL-3.0-only. See the license and component notices.
Created and maintained by DrawSplat Developer(s). Visit DrawSplat Wiki for help. Optional district setup and professional learning services are listed on the pricing page.
Productivity hides classroom-only controls. Choose Education Tools to reveal class, student, answer-key, turn-in, and moderation features.
Simple focuses on the core drawing tools. Advanced reveals the full toolkit.
Google setup, room defaults, and classroom sharing settings are managed on the Teacher Admin page so students never see provider settings.
Deletes every panel and starts with a blank single panel. Undo or the saved recovery checkpoint can bring your work back.
The script stores board JSON and PNG exports in Drive and logs saves in the Sheet. It can also store shared room states for cloud collaboration.
Select two or more images, then create a single mosaic image.
Select two or more images, then choose a collage layout with a text banner.
