Why NoteGen

Capturing should not force you to organize immediately.

When an idea appears, you rarely know which folder it belongs in or whether it will become a report, article, or project note. NoteGen captures it first and organizes it when you actually need it.

Powerful when needed

AI, canvas, and Markdown in one workflow.

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