Writing

Real pages, laid out as they’ll print.

Set the paper, font, spacing and margins once. Running heads and page numbers are added for you. Start from a template such as Standard Manuscript or 50,000 in November.

Characters & Locations

Keep track of everyone.

Sonetia finds the names in your manuscript. See how often each character appears, who they share scenes with, and how they’re related.

Plot Board

Plan on index cards.

Every chapter becomes a card. Drag the cards to try a new order. Your manuscript doesn’t change until you move the chapters yourself.

Everything else a novel needs.

Notebooks

Collect notes, images and research outside the manuscript. Photograph a handwritten page and Sonetia turns it into text.
