Jiraiya Split View Editor
WHY JIRAIYA

You have something to say. Where do you start?

More chapters can make the flow harder to follow. Planning can interrupt drafting. Rereading can miss awkward phrasing.
Keep your outline beside the text, move chapters as the story develops, and listen back with built-in voices. You can try all three with one book for free.

FEATURES

Keep the whole book in view as you write.

Create a book with a working title. Add a few headings and write one short section.
Change the order when you need to. You do not need a finished plan to begin.

📚

Split View Editor

Outline on the left, detail editor on the right. Get the big picture while focusing on one chapter. Freely resize panel widths to match your workflow.

🗂️

Structure Panel

See your heading hierarchy at a glance. Drag and drop to rearrange chapters, collapse and expand to show only what you need. Try a different order without moving the text by hand.

✍️

Markdown Editor

AUDIO · MAC

Hear what you might miss on the page.

Hear the rhythm of your manuscript with the voices built into your Mac. Read-aloud is free. Exporting a chaptered M4B requires Pro.

Read aloud with built-in voices

No additional voice software needed. Listen to a section or the whole book, adjust speed, pause, and follow the highlighted paragraph. Your manuscript is not sent to an external service.

Export a chaptered audiobook

With Pro, create an M4B locally using a built-in Mac voice, then listen in Apple Books. Images and tables are excluded from narration.

Choose another voice

VOICEPEAK requires a licensed compatible product and a helper on the same Mac. ElevenLabs requires your own API key and approval to send the narration text. Its fees and usage allowance are separate from Pro. Using Voice Library voices through the API requires a paid ElevenLabs plan.

Writing does not automatically send your manuscript to ElevenLabs. Once sent, storage and use follow its terms and your settings. How audio features handle your data

APPLE INTELLIGENCE

Gather material on iPhone and iPad, then write on Mac. Availability varies by device and OS. Sage Mode requires an Apple Intelligence capable device.
