Your way of writing
StoryBook can help you write. But it doesn’t stop there.
Some writers want help drafting. Others want to write every word themselves.
StoryBook supports both — and everything in between.
Writing the words is one part of the work. Understanding what you’ve written is another.
StoryBook helps with both.
Think with AI
When you need a sounding board.
Brainstorm, interview characters, explore your world and ask questions about ideas you are considering.
Let AI read
When the words should remain yours.
Write every sentence yourself, then use StoryBook to proofread, analyze, check continuity and discuss the manuscript you actually wrote.
Yours to keep
Your stories are yours.
Your writing tools should be too.
StoryBook AI is free, open source and local by design. No subscription is required to keep writing, and your manuscript stays on your own computer.
