Describe what you want to do with your font in your
natural language. The assistant will generate Python
code using the context library and
run it.
adjustContext matters: Work either on
the font directly (Font Context), or on a
user-made script in the script editor (Script
Context)
syncAuto-retry: If code fails, the
assistant will fix and retry
keyPrivacy: Your font data never
leaves the browser. The assistant simply
generates Python code which is run locally like
a user-made script.
visibilityTransparent: Click "Show Code"
to see what was generated
boltAuto-Run: Decide whether to run
the generated code right away or wait and review
before running
warningWarning: The assistant makes
mistakes both in handling your data as well as
in generating code. Use at your own risk.
Examples: "List all glyph names", "Make glyphs 10%
wider", "Add 50 units to left
sidebearings"
