Annotations

Highlight text and add notes to your sources.

Annotations let you highlight important passages and attach notes directly to your sources. They work on PDFs and text-based content (web pages and text sources).

Creating a highlight

Select text in a PDF or article. A small toolbar appears above your selection with five color swatches: yellow, green, blue, pink, and purple. Click a color to create the highlight instantly.

Adding a note to a highlight

When the highlight toolbar appears, click the message icon next to the color swatches. A text area opens below the toolbar where you can type your note. Press Cmd+Enter (Mac) or Ctrl+Enter (Windows/Linux) to save, or click the Save button.

Standalone notes

Click the + Note button at the top of the Annotations tab to add a note without highlighting any text. Choose a color, write your note, and click Save Note.

Viewing annotations

Open the Annotations tab in the source detail sidebar to see all your highlights and notes. Annotations are sorted by their position in the source (by page for PDFs, by location for text). Click any annotation to scroll to its location in the viewer.

Each annotation card shows:

• A color dot and icon (highlighter for highlights, sticky note for standalone notes)
• The page number (for PDF annotations)
• A timestamp showing when it was created
• The highlighted text (if any), shown in italics
• Your note (if any)

Editing annotations

Click the three-dot menu (···) on any annotation card in the sidebar to:

• Add Note or Edit Note - add or update the note text
• Change Color - pick a different color from the five options
• Delete - permanently remove the highlight and any attached note

Highlight colors

Five colors are available for organizing your annotations:

• Yellow (default)
• Green
• Blue
• Pink
• Purple
