Chapterra

Translate Your Manuscript, Then Polish It

Machine translation alone reads like machine translation. Chapterra translates your book and then applies a real editing pass, proofread, copyedit, or line edit, so the result reads naturally and keeps your tone and voice across languages.

Upload a DOCX, EPUB, or TXT. No account needed to start.

Translation plus editing, in one pass

Upload your manuscript and select Translate mode, then pick the editing level you want applied to the translated text. The output is a translation that has actually been edited, not a raw dump.

Check quality first

Generate your Beta Read Report before translating to confirm the book is in good shape. Then translate and polish, chapter by chapter or all at once.

Frequently asked

Is my manuscript private?

Yes. Your manuscript is processed in your browser and sent directly to the AI provider you choose (OpenAI, Anthropic, or Google). Chapterra never stores your content on its servers.
