DrawSplat

DrawSplat is a free, browser-based workspace that collects small single-purpose tools for teaching. Teach with the collaborative whiteboard, or open a focused environment: GridSplat for spreadsheets, formulas and charts, ShowSplat for slides, WriteSplat for classroom documents, ListSplat for simple databases, plus a quiz and flashcard studio, image editor, chart builder, video editor and Markdown studio. Saved work and preferences live in the browser's local storage, and cloud save is opt-in.

What you can do with it

• Build a lesson artifact in the browser with no install and no account.
• Draw and annotate a diagram, then export it for a handout or slide.
• Make a concept map, chart or picture graph from classroom or CSV data.
• Build quizzes, team activities and printable flashcards.
• Anonymize or trim a video before sharing it with a class.

Who it is for

Teachers and students who need a tool quickly and cannot wait for a district license, and schools that want a low-friction alternative to a stack of subscriptions. The site publishes privacy and Accessibility statements, a district addendum and a Texas compliance page, which is the paperwork a school needs before it can approve a browser tool.

Notes

The product site names no individual author and routes requests to a project inbox; DrawSplat is built by Miguel Guhlin, whose site documents its launches. The code is free in the license sense, not only the price sense: the whiteboard is GNU AGPL-3.0-or-later and the SplatWorks apps are GPL-3.0-only, with no per-seat license on student devices. Tools that read your files run locally in the browser, while cloud save and any professional-learning request do send data, so check the storage inventory page before using it with student work.
