Chapterra

Your Personal AI Writing Coach

Ask questions about the selected chapter, explore a character decision or discuss a scene. The current chat includes bounded selected-chapter text; it does not automatically know every detail of your whole book.

Opens the app. Check the selected mode, account access and job estimate.

Ask a specific question

Point to a scene or decision and say what troubles you. Ask for evidence from the chapter rather than a generic list of writing tips.

Choose the right access mode

Chapterra has provided-access modes and a separate own-API-key option. If it asks for a provider key, check which mode you selected. Smart access depends on the account or own-key configuration; check the app before starting.

Frequently asked

Can the tools help with an unfinished draft?

You can use chat to discuss a selected chapter and explore revision notes. Cowrite is a separate workflow still being refined. Neither feature guarantees a finished book in your voice.
