Second brains

Helps writing quick drafts. Ignore the V2 version. V3 is stable and much better.

FLOSS "second brain" application. Unlike most alternatives it doesn't use the 'md files in folders' format internally. But in practice it's hardly a con because it feels the same, only quicker (faster performance, faster UX).

Helps writing fiction with characters, scenes, etc.

Helps writing both fiction and non-fiction.
