Flowchart maker
A flowchart maker as fast as you think.
Flowcharts shouldn’t mean nudging boxes and redrawing arrows. In Builderii you add the next step from the keyboard, arrows find their own way around, and the chart lays itself out again whenever it gets messy. Or describe the process and let the AI draw it.

In short
Builderii is a free online flowchart maker built for speed. Select a step and press ⌥+Arrow to add the next one, connected; elbow arrows route around other shapes; one click lays the whole chart out top to bottom or left to right. Flowchart shapes cover start and end, process, decision, input/output, document, database and subprocess, and the AI can draw or change a chart from a sentence.

How it works
Make a flowchart without the mouse.
Start a step
Press R for a rectangle (or D for a diamond) and click.
Add the next one
⌥+Arrow adds a connected shape in that direction; a decision’s next step is a rounded step.
Label it
Type to name a step; double-click an arrow to label it “Yes” or “No”.
Tidy it
⇧⌥V lays it out top to bottom, ⇧⌥H left to right.
