How to make a flowchart in LetDraw

From a blank canvas to a shareable flowchart in a few minutes, right in your browser.

  1. Open a canvas

    Start blank or pick the Flowchart template from the template gallery.

  2. Add the steps

    Drop start, process and decision shapes from the flowchart shape library, then type the labels.

  3. Connect them

    Draw arrows between shapes. They stay attached when you move things, and smart connectors route around other shapes.

  4. Share or export

    Send a link, edit together in real time, or export the flowchart as PNG, SVG or PDF.

Faster than drawing box by box

Flowcharts from code or a sentence

Already have a flowchart in Mermaid? Paste it and get real, movable shapes in the sketchy style, then export it back to Mermaid or D2 whenever you need code again. Or describe the process in plain words and let the AI draft the first version for you to edit.

  • Mermaid and D2 import, turned into editable flowchart shapes
  • Prompt to Diagram drafts a flowchart from a description
  • Smart connectors that route around shapes instead of crossing them

What people draw

A flowchart for every kind of process

The same canvas works for a two-step approval and a fifty-step operating procedure.

Business processes

Map how an order, a refund or an approval really moves through your team, and spot the bottlenecks.

Algorithms and logic

Sketch the branches of a function or a retry policy before you write the code.

User and onboarding flows

Lay out sign-up, onboarding and checkout screens as a flow everyone on the team can follow.

Decision trees

Turn support playbooks and troubleshooting guides into clear yes or no paths.

Standard procedures

Document recurring tasks once, keep them in a shared workspace and update them as the process changes.

Teaching and workshops

Draw live in front of a class or a room, then share the board so everyone keeps a copy.
