Steps

  1. Get your own manuscript out of Kakuyomu (official export, or copy the text from the editor). Official help (Japanese)
  2. In BunCho, open Import in the work list and choose the TXT, Markdown, DOCX or EPUB file (up to 2 MB / 200 sections). Check the chapter preview and save a private draft. Importing uses no AI credits.
  3. Write and revise with Tab completion, ⌘K rewrites and Agent edits; every AI change is shown as a diff before you accept it.
  4. Use "Export for posting" and paste each episode back into Kakuyomu. Ruby notation on Kakuyomu: 漢字《るび》、漢字以外を含むときは ｜親文字《るび》（親文字は20文字・ルビは50文字まで）. Notation help (Japanese)
  5. If you used AI, follow Kakuyomu's AI disclosure rules. Official AI policy (Japanese)
