Open-source novel writing software with character and scene planning tools
Bibisco is novel-writing software rather than an AI service. It organises a book into chapters and scenes, and gives each character, place and object its own structured profile so you can track relationships, motivations and timeline without a separate notes file. Several of its most useful features are interviewing tools: it asks guided questions about a character and stores the answers, which writers use to break through planning stalls. The project is open source, and a paid version adds cloud sync and a portable install. AI features are minimal, so treat it as a planning and drafting environment.

The free edition is open source and covers planning and drafting a full novel, which is why many writers never upgrade. The paid version mainly adds cloud sync and conveniences such as a portable install, so check which of those you actually need.
Yes, that is where the structured profiles pay off: characters, places, objects and timeline notes stay attached to the project, so continuity across several books is easier to maintain than in a plain text file.
