Lionote

Lionote is a note-taking software that supports all platforms, allows handwriting, has AI Q&A, and protects privacy. You can freely use a variety of information forms for recording and creation (text, handwritten whiteboard, mind map, flowchart, sequence diagram (UML), Markdown, AI Q&A, recording, pictures, files, etc.). It is based on notes but goes beyond them. It offers local storage, can be used offline, automatically encrypts and synchronizes across all devices, and no one else can see your notes. It meets the needs of scenarios such as learning, work, encrypted diaries, teaching, presentations, memos, and to-do lists. The core functions are permanently free.
