[Sound cue: coffee machine beeps]At 8:57, Sam was halfway out the door when the coffee machine beeped.
He turned back, found his keys beside the mug, and congratulated himself on a remarkably organized morning.
[Sound cue: mug clinks]His mug clinked onto the desk.
[Sound cue: phone chimes]Then his phone chimed.
The online meeting had started.
He took one careful sip, squared his shoulders, and joined the call with an expression of complete professionalism.
His camera was upside down.
Twelve coworkers were politely studying the ceiling.

Shape the delivery with expressive directions and vocal cues
Mark selected passages with expressive directions and add vocal cues where they belong, when supported by your selected narration engine.
Currently supported with xAI only. Performance varies; this recording is an illustrative example.
In the directed Orion example, the middle sentence is marked soft and slow, followed by a sigh before the final sentence. The sigh is a vocal cue, not an added sound effect.

The room grew quiet.
[Expressive direction: soft, slow] Take a quiet moment before we continue.
[Vocal cue: sigh] Now we can begin again.
Project Library
Keep your book's files in order
Keep shared reference, pronunciations, media, and effects together in Project Library, with file previews and folders to stay organized.
Project Settings helps keep typography, headings, and narration consistent across your project.
Move or rename files and optionally update supported references in current content. Manuscript prose and saved versions stay unchanged.
Continuity with context
Reference and Guidance lives beside the manuscript
Keep characters, places, terminology, and creative direction close to the work so collaborators and optional agents share the same context.
You approve every proposal
Agents suggest updates to Reference and Guidance. You decide which proposals to accept; agents cannot directly rewrite your manuscript.
Technical and educational writing
Set inline and display math without leaving the editor
Compose equations in context and keep mathematical notation with the surrounding manuscript for ebook output.
Equations are included in EPUB output. Audio previews do not narrate equations.
A workspace that grows with the book
Work independently or invite the right help
Focused collaboration
Organize projects, books, and manuscripts, then bring collaborators into the work you share.
Optional AI
Use agent assistance when it fits your process, or keep writing without it. Proposed changes remain reviewable.
Welcome Project
Explore the Project Library and try narrated examples with expressive directions and vocal cues in the Welcome Project. Follow the guide and help articles to get started.
