Open Project Settings immediately above Project library in the Explorer. It starts collapsed. Choose General, Typography, Headings & contents, or Voices to edit in the main workspace. Switching sections keeps your drafts and scroll position. Save changes saves all changed sections and keeps the page open. In nested editors, Apply changes adds edits to the project draft; save the project afterward. Leaving with unsaved edits offers keep or discard. Book and manuscript settings remain in their own dialogs; they can override inherited project defaults where supported. Provider secrets are never retained after leaving the project settings session.
Provider keys appears only for users approved to use their own provider keys (BYOK). Silence at the edges of synthesized speech is trimmed automatically; there is no toggle. Authored pauses and heading/block timing are unchanged.
General contains only the project chat toggle. Put project background and author guidance in Project library > Reference and Guidance, not a description field. Existing description metadata is preserved; saving settings neither migrates it nor overwrites the reference document.
Reference material is separate: open Project library > Reference and Guidance. Update with agent proposes changes for your approval; it never replaces accepted text without confirmation.
Expand Project library in the Explorer. Reference and Guidance comes first, then Pronunciations, Images, Audio, Files, and Effects. Pronunciations apply to the entire project and save directly. Its overview offers Upload but no file lists. Choose Images, Audio, or Files beneath Project library to browse files in the work area. Actions depend on your permissions.
Audio reuse is an advanced setting. Group reusable audio by shows heading levels with their configured names; a level is not necessarily a chapter. Pause narration pauses the voice while a sound cue plays. Sound effects add sounds to the story; voice effects change narration.
