This page contains lists of software that are replacements or alternatives to proprietary counterparts or are only available on other platforms (Windows, Mac).
CAS (Computer Algebra System)
FOSS alternatives to Mathematica and Maple (without an equation editor):
- Xournalpp (rewrite of Xournal in C++. Very active, but not quite there yet in terms of features to OneNote) AlphaCubed personally recommends this one.
- Trilium (Very active project. has a different type of way to organize your notes. Need your own server to sync. Uses the Electron library - you might not like this.) AlphaCubed personally recommends this one.
- Joplin (Sort of active project. Markdown, desktop application annoying to use because of no WYSIWYG capabilities (yet). Syncs with Nextcloud/Owncloud/WebDAV servers. Has mobile applications (yay!) Uses the Electron library - you might not like this.)
- Bakoma-TeX (If you like LaTeX for note-taking, this includes a WYSIWYG editor. Probably no WYSIWYG drawing capabilities. Handwritten math only on Windows because it uses its math writing input thingy. Has Linux version, but costly.)
- Turtl (Recently had a big update. More like sticky notes with limited text input capabilities. Has mobile applications (yay!) Uses the Electron library - you might not like this.)
- µPad (basically a clone of Onenote's note organization, but with no rich text or drawing color (yet). Paid sync service - probably can self-host.)
- CherryTree (has hierarchy, like a binder)
- Old, no longer being maintained (probably): Xournal (for handwriting/text anywhere on page)
