Colorize: Batch-Color Your Pages with AI

The Colorize tab (API mode) works just like Sketch’s Make tab: press Run Rest, and every page without a colored version is queued and generated using its Color Prompt from the plan.

Toolbar Reference

Control	What it does
Import images (icon button)	Bring in externally colored images instead of generating.
Cost / Quality toggle	Generation quality tier for coloring, independent of the Sketch toggle. In most cases Cost already produces satisfying results; switch to Quality when a page deserves the best possible pass.
Run Rest	Colors only the pages that don’t have a colored version yet — never re-bills finished pages. Your default button.
Run All	Colors every page with a valid prompt. Skips nothing, so use it deliberately.
Stop	Appears during a run; aborts the queue. Queued pages return to empty; pages already generated are kept.

Working the Grid

Cards move through the same states as Sketch: In Queue → Generating… → done, with a red Retry state on failure.

• Click an empty card to color just that page.
• Hover a finished card for two buttons: edit (opens the edit dialog below) and retry (regenerate from scratch).
• Amber warning triangle on an empty card — that page has no Color Prompt. It can still generate (the AI picks colors on its own), and the app will ask first: “This page has no color prompt — the AI will choose colors on its own. Generate without one?” with Write a Color Prompt (jumps to the plan) or Continue Anyway.
• Right-click any card → Show in Explorer to find the file on disk.

Editing a Colored Page

The Edit Image with AI dialog works exactly like the Sketch one: describe changes in Additional requirements (e.g., “make the colors more vibrant, change the sky to sunset”) to refine the current image, or unlock and rewrite the Color Direction to regenerate from scratch. # mentions of Image Pool characters are supported in both fields.

Local Mode

When Coloring is routed to Local AI, this same Colorize tab runs the model on your own GPU instead of the cloud — Run Rest and Run All behave exactly as above, but generate on-device with no per-image API cost. The first local run checks that the model is present and offers a one-time Start Download (~7.4 GB, three files); after that the grid, states, and editing are identical to API mode.

Local AI is the zero-cost default. For a cover or preview you’ll sell, the API still gives the cleanest reproduction of your line-art — see the stage overview for how to route each pass.
