About

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.

• 🎯 Context matters: Work either on the font directly (Font Context), or on a user-made script in the script editor (Script Context)
• 🔄 Auto-retry: If code fails, the assistant will fix and retry
• 🔑 Privacy: Your font data never leaves the browser. The assistant simply generates Python code which is run locally like a user-made script.
• 👁️ Transparent: Click "Show Code" to see what was generated
• 👁️ Auto-Run: Decide whether to run the generated code right away or wait and review before running
• ⚠️ Warning: 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"
