Why NoteGen

You don't need to decide where a note belongs before writing it down.

Capture an idea without sorting it immediately. When writing a report, article, or project document, select the records you need.

Powerful when needed

AI, canvas, and Markdown in one workflow.

Daily capture stays simple; advanced tools appear when you need them.
