Available in six colors with basic formatting and adjustable text size. Notes are colored cards for short, standalone pieces of information. They're useful for quick reminders, temporary information, or anything that doesn't need the structure of a full document. Notes on canvas in different colors Your AI cofounder creates notes when something is worth capturing but doesn't warrant a document. You can also create notes yourself using the + button at the bottom of the canvas. ## Notes vs documents Use notes for brief, self-contained information. A key insight from a conversation, a reminder about something to revisit, a quick reference you want visible on the canvas. Use [documents](/documents) when you need structure, length, or rich formatting. Product specs, research findings, competitor analysis, feature descriptions. Documents support headings, lists, task lists, code blocks, and more. If you're unsure, lean toward documents. Notes are best when brevity is the point. ## Colors Notes come in six colors: yellow, green, peach, pink, blue, and purple. Yellow is the default. Click a note to select it, then use the color picker in the toolbar to change its color. Colors are purely visual, so use them however makes sense for your project. You might color-code by topic, by status, or just by preference. ## Formatting Notes support basic text formatting: * **Bold** for emphasis * *Italic* for softer emphasis * ~~Strikethrough~~ for crossing things out Text in notes is centered. For more formatting options like headings, lists, or code blocks, use a document instead. Note selected with toolbar showing color picker and text size You can also adjust the text size. Click a note to select it, then use the size picker in the toolbar to choose from a range of sizes. Larger sizes work well for notes that serve as headers or labels on the canvas. ## Editing and resizing Click a note once to select it, which reveals the toolbar. Click again to start editing the text. Drag the left or right edge of a note to adjust its width. Notes have a minimum height, but they expand automatically as you add content. Changes save automatically as you type. ## Downloading Export any note in the format you need: Word, PDF, Text, or Markdown. Access download options from the note's menu.
