Use the editor (2024) is a free and open source diagramming app that you can use online at, and offline ( desktop).

As a security-first diagramming app for teams, we provide the diagramming functionality, and you choose where to keep your diagram data. There are many different integrations with other platforms and applications, including Atlassian Confluence Cloud, Google Documents, GitHub, Microsoft Word.

Our diagram editor looks the same and offers the same main features no matter where you are using it. You can open a diagram created in one integration in another.

The editor

Like most diagramming apps, the items you see in the toolbar and the panels around the drawing canvas are context sensitive. Tools and options will be displayed depending on the type of element(s) you have selected on the drawing canvas.

If you have used diagramming tools before, you will be familiar with the diagram editor layout.

Tip: Hover your mouse over any button, tool or option in the editor to see a tooltip that says what it is used for.

Shapes and shape libraries

Shapes are arranged into logical groups, called shape libraries. Not all of the shape libraries are shown at once as there are simply too many of them.

Tip: Expand or collapse each shape library in the left panel by clicking on its name.

Enable/disable shape libraries

To make creating a diagram easier, enable only the shape libraries that you need for the particular diagram you are working on.

  1. Click on More Shapes at the bottom of the left panel.
  2. Scroll through the various shape libraries - these are arranged into useful categories for the different types of diagrams. Click on the checkbox next to a shape library’s name to enable or disable it.
    Use the editor (9)
  3. Click Apply.

See how to add shapes to the drawing canvas


The scratchpad is your personal shape library where you can add the shapes or groups of shapes that you use the most often.

  1. Drag one or more selected shapes from the drawing canvas onto the scratchpad.
  2. Click on one of the shapes or groups of shapes you have saved to the scratchpad to add another copy to the drawing canvas, just like you would a shape from the shape libraries.

Search shapes

There are so many shapes organised into so many libraries, that they can be hard to find. Type the name of a shape into the shape search field, and you’ll get a number of matches. This also finds matching clipart shapes if you are online.

Tip: If you don’t find the shape you are looking for, try searching for a related word.

Drawing canvas

Draw your diagram by placing, connecting and styling shapes on the drawing canvas in the middle of the editor. The drawing canvas displays a grid by default to help you align and space shapes neatly.

  • Pan the drawing canvas with the scroll bars, or right-click/middle-click in an empty area on the drawing canvas and drag to move the canvas around. Use the mouse scroll wheel to move the canvas vertically.
  • Zoom in and out using the Zoom In/Zoom Out tools in the toolbar, or hold down Ctrl on Windows, or Cmd on macOS and use the scroll wheel to zoom into and out of the drawing canvas. This does not change the size of your diagram.

Tip: Enable the rulers via the View menu.

Move the drawing canvas on touchscreens and in the outline panel

Page tabs

Organise complex diagrams into multiple pages.

  • Click on (vertical ellipses) underneath the drawing canvas to access the diagram page menu.
  • Click on the page tabs to view that page.
  • Add a new page by clicking on + (plus).

Format panel

The format panel on the right contains options and properties that you can change to arrange and style your shapes, connectors, text and diagram.

What you see is context sensitive. For example, when you click on a connector, you will see additional styling options that can only be applied to connectors. If you select only text and no shapes or connectors, you’ll see only the text styling options.

Style tab

When you have selected one or more shapes, you can change the fill and outline colour of shapes, edit styles, copy and paste styles in the Style tab in the format panel on the right. You can change how a selected connector is drawn - curved, straight or with sharp right-angles, if it is a broken line or solid, whether line jumps are used and which arrows are used at either end of the connector, and more.

Compare the different style options below when a shape is selected (left) and when a connector is selected (right).

To learn how to work with styles, follow our basic flow chart tutorial.

Text tab

Change the font, size and style of your labels using the Text tab of the format panel on the right. You can also change the vertical and horizontal alignment of the text, the writing direction, the font and background colour and opacity, and add spacing around the text.

Word Wrap and Formatted Text are enabled by default. This lets you style characters and words inside the label text as if it were HTML, which also supports hyperlinks.

Tip: Double click on text to edit the text and select part of a label. Then, only the Text tab is displayed (right) as you are not editing a shape.

Click Edit Data to manually edit the selected shape’s metadata, or Edit Link to add a hyperlink.

Note: The Arrange tab shows fewer options when you select a connector (right) than when you select a shape (left).
