Artists need generative exploration that preserves their sketch and clearly separates suggested variations from the original. On a phone, the person also needs to capture information quickly, understand where an answer came from and return to the original material without navigating through a dense desktop interface.

• Keep sketch canvas and variation lab connected within a short mobile flow.
• Make sketch-guided variation correctable when the model misreads the input.
• Explain reference retrieval through visible references or user-selected preferences.
• Keep changes, sharing and data retention under explicit user control.

The design begins with an edge-to-edge sketch canvas with floating tool puck, using large touch targets, short task sequences and contextual sheets. Generate exploratory treatments from the artist's chosen drawing. Suggest colors from a reference photo for manual adjustment. The companion views keep drafts, original material and accepted decisions distinct. A ink, ultramarine and warm white visual system gives this app its own character within the collection.

• Generate exploratory treatments from the artist's chosen drawing.
• Suggest colors from a reference photo for manual adjustment.
• Find related studies within the user's own sketch archive.
• Turn a short creative direction into editable variation controls.
