FAQ

Is Notium an Excalidraw replacement?

Notium is best described as an Excalidraw alternative for users who also need notebooks, templates, Mermaid import, frame presentations, sharing, and AI-assisted diagram creation.

Can I import Excalidraw files into Notium?

Notium uses its own native file and document model. The product direction is inspired by familiar whiteboard workflows, but Notium is not built around Excalidraw files.
