About

Slate Composer builds delivery slates with live canvas preview, reusable local projects, tab-based slate variations, and high-bit-depth export formats.

Core Workflow

• Set canvas, background, typography, title/subtitle, date, and block/image positions in the left controls.
• Edit slate text in the composition editor under preview (supports syntax directives below).
• Use project tabs for per-version slates, then export one slate or all tabs.
• Toggle Guides to show position guides and snap X/Y controls.

Keyboard Hotkeys

• Cmd/Ctrl + Shift + Z or Cmd/Ctrl + Y: Redo

• Double-click any range slider: Reset to its default value
