Desktop recommended

Read on phone, write on desktop.

The editor needs more space than a small screen can give. Keep exploring here, then open Chart Mage on your laptop to start drawing.

Why it feels fast

Three cards, one promise.

Less flicker, more certainty. The product stays quiet while the syntax and canvas do the work.

No layout fiddling

Type the relationships, not the geometry. Chart Mage resolves spacing, arrows, and hierarchy for you.

Smart autocomplete

Participants, arrows, notes, loops, and fragments stay close at hand, so the editor keeps up with your typing cadence.

Syntax you can read aloud

User ->> API: checkout says exactly what it does. You can learn it in ten seconds and keep it in muscle memory.

Built for crisp handoff

A clean canvas, not a clean slate.

Charts stay local, export as PNG, and remain easy to version because the source is still just text. Draft quickly, share cleanly.
