Chapter Content

Upload from your device

The standard path for inserting an image from your computer.

1. Place your cursor in the chapter where you want the image to appear.
2. Click the `Image` button in the left sidebar.
3. In the small menu that opens, click `Upload Image`.
4. Pick a file from your computer. The image inserts at your cursor.
5. Drag the corner handles to resize.

Paste from clipboard

Faster for screenshots and copied web images. Click into the chapter where you want it, press `Cmd+V` (Mac) or `Ctrl+V` (Windows), and the image uploads and inserts in one step. No menu needed.

Good to know

• Drag the corner handles to resize after placing.
• Large images are auto-compressed on upload.
• Images are block elements (between paragraphs), not inline.
• Click an image once, press `Delete` or `Backspace` to remove.

Steps

Place your cursor where the image should go, click the `Image` button in the left sidebar, then pick `Generate Illustration` from the menu. The dialog shows the current chapter and your remaining quota.

Choose a style: Auto matches your book's genre, or pick a look such as Watercolour, Line art, Cinematic, Flat vector, Storybook, Photo, or Minimal.

The "What to show" field is optional: leave it blank to draw from the chapter's content, or describe a subject (e.g. "a runner at sunrise"). Click `Generate`; the illustration drops in at your cursor.

Cost and limits

Paid feature with a monthly account allowance plus credit overflow:

• Creator: 20 illustrations per month.
• Premium and AppSumo: 50 illustrations per month.
• Beyond your allowance: chapter credits cover extras (1 credit per image).

Steps

Select the text you want to format, then click the `Aa` Text button in the left sidebar. A formatting panel opens with bold, italic, underline, headings, bullet and numbered lists, alignment, font size, and font family. Click the option you want and it applies to your selection.

For the basics, keyboard shortcuts skip the panel entirely: `Cmd+B` / `Ctrl+B` for bold, `Cmd+I` / `Ctrl+I` for italic, `Cmd+U` / `Ctrl+U` for underline.

Steps

The colour applies only to the selected text.

1. Highlight the words, paragraph, or block you want to recolour. Use `Cmd+A` (Mac) or `Ctrl+A` (Windows) inside the chapter to select the whole chapter.
2. Click the `Aa` Text button in the left sidebar. The formatting panel opens.
3. Click `Text colour` in the panel. A small swatch grid opens with a `Custom` button for entering a hex code.
4. Pick a swatch or click `Custom` to enter a hex value. The change applies instantly.

Quote blocks

Add a styled pull-quote from the Text panel.

1. Place your cursor on the line you want to turn into a quote.
2. Click the `Aa` Text button in the left sidebar to open the formatting panel.
3. Click the Quote icon (next to the Numbered list button).
4. Click the Quote icon again to unwrap the quote.

Callout boxes (Tip, Note, Warning, Important)

Callouts are auto-styled at export time. No separate button in the editor. Start a paragraph with a trigger word and a colon; each colour maps to a trigger:

1. Start a paragraph with a trigger word and a colon. Example: "`Tip:` Always preheat the oven before baking."
2. Open the Export dialog, expand Decorations, and toggle Callout boxes ON.
3. Export your book. The paragraphs render as styled boxes; without the toggle they stay as plain text.

Recipe cards (Ingredients, Instructions)

Recipe cards are auto-styled at export time too.

1. Inside a chapter, add a heading (H2, H3, or H4) named one of: `Ingredients`, `Instructions`, Directions, Method, Preparation, or Recipe.
2. Immediately below the heading, add a bullet or numbered list (both live in the `Aa` Text panel) with your items.
3. Open the Export dialog, expand Decorations, and toggle Recipe cards ON.
4. Export your book. The heading + list pair renders as a bordered card with a coloured header bar.

• Items must be a bullet or numbered list from the `Aa` Text panel. Plain paragraphs with line breaks will not trigger the card.
• Each heading + list pair becomes its own card, so `Ingredients` and `Instructions` render as two cards.

Add a section break

Place your cursor on a new empty line inside the chapter. Type three dashes (`---`) then press Enter. The dashes are replaced with a thin horizontal line that separates the sections above and below it. The line survives PDF, EPUB, and DOCX exports.

Remove a section break

Click on the line once to select it (you will see a thin highlight around it), then press `Delete` or `Backspace`. Your cursor returns to the previous line so you can keep writing.

Find and replace text

Open Tools (the wrench icon in the editor sidebar) and use Find & Replace. Type the text to find and what to replace it with. On a book with more than one chapter you can switch the scope between This chapter and Whole book, and a live count shows how many matches will change. Turn on Match case or Whole word for precise matches, then click Replace all.

Rename a character everywhere

To change a character’s name, put the old name in Find and the new name in Replace, set the scope to Whole book, and click Replace all. If the name matches one the AI already knows for this book, a checkbox appears: "Also update this book’s character list (recommended)". Leave it ticked so the AI keeps using the new name, including if you regenerate a chapter later.

Change the case of selected text

Select the text you want to convert. Open `Tools` (the wrench icon in the editor sidebar), then click `Change case`. Pick UPPER for ALL CAPS, lower for all lowercase, Title Case for capitalised words, or Sentence case for capital-first-word only. The transformation applies to your selection and the highlight stays in place, so you can apply a different case immediately if it is not what you wanted.

Check the readability of a chapter

Open Tools (the wrench icon in the editor sidebar) and click Readability. You will see three things for the current chapter: a Flesch reading-ease score, an approximate US grade level, and a plain-English label (e.g. "Easy", "Fairly easy", "Standard", "Difficult"). The score updates as you edit the chapter, so you can shorten sentences or pick simpler words and watch it move.

Most commercial non-fiction aims for a Flesch score of 60-70 (around US grade 8-9). Self-help and broad-audience books usually target 70-80. Technical and academic writing often lands at 30-50, which is harder but appropriate for the audience. The score is a guide, not a rule.

It is per-chapter, not whole-book

The score reflects only the chapter currently open. Switching chapters re-scores against the new one. Whole-book readability is not displayed because each chapter typically has a different purpose (introduction vs reference vs reflection) and a single average would hide useful variation.

Turn spellcheck on or off

Open `Tools` (the wrench icon in the editor sidebar). At the top is a `Spellcheck` switch. Flip it on to get the browser's native red-underline spellcheck across the chapter. Flip it off to hide all squiggles, which is useful when an AI-generated draft is full of names, places, or invented terms the dictionary does not know.

Your setting is remembered on this device. Switching devices will use that device's last choice. There is no global account-level setting today.

Apply a font choice to every chapter

Open the `Aa` menu (the Text icon in the editor sidebar). At the bottom under Typography there are two controls: font size and font family. Each has its own `Apply to all chapters` checkbox directly beneath it. Tick the relevant box, then pick the size or font you want, and the change propagates across every chapter in one go.

The two toggles are independent. You can apply a font family across the whole book while leaving font sizes per-chapter, or vice versa. The toggles only fire on the next selection, so changing your mind is just a matter of un-ticking and picking again.

When this is useful

Most books read better with a single body font and size throughout. When you import a draft or generate with AI, individual chapters can end up with mixed sizes from copy-paste artifacts. One pass with "Apply to all chapters" ticked is the fastest way to make the whole book consistent before exporting.

Insert a page break inside a chapter

Click in the chapter where you want the break (anything after the cursor will start on a new page). Open the `Aa` menu (the Text icon in the editor sidebar) and scroll to the `Insert` section. Click `Page break`. A dashed divider appears in the editor so you can see where the break is. In the PDF export, the divider becomes an actual page break and the content after it starts on a fresh page.

When to use it

Page breaks are handy at the end of a long section, before a recipe or worksheet you want on its own page, or before a closing thought you want isolated. Chapters already start on a new page automatically, so you only need a page break inside a chapter, not between them.
