Free means free.
StoryBook AI is free and open source. No subscriptions, no StoryBook AI credits and no premium feature tier.
StoryBook AI is free, open source and runs on your own computer. There is no subscription to maintain, no monthly StoryBook AI credit allowance and no StoryBook service that has to remain online for you to keep writing. Your manuscript and your writing environment remain yours.
Use it
Write without a recurring StoryBook fee.
Inspect it
The source is public, so the application can be examined rather than treated as a black box.
Modify it
Under GPLv3, the code can be modified and redistributed under the licence terms.
Privacy you can verify.
StoryBook's local-first architecture is visible in the source. You can inspect how manuscripts are stored, how the local AI endpoint is used and whether the application sends analytics or telemetry.
Open source turns the privacy promise into something technically inspectable.
Built in the open.
You do not need to write code to contribute. Use StoryBook, report bugs, suggest improvements, improve documentation, help with translations or share the project with other writers.
Support StoryBook.
Using StoryBook costs nothing. If it is useful to you and you want to support continued development, voluntary donations can help — without changing what features you receive.
