API Keys

Anthropic — used for layer detection

Replicate — used for transparent-bg extraction (optional)

Both keys are stored locally in this browser only. The Anthropic key calls api.anthropic.com for box detection. The Replicate key runs SAM-2 (precise prompted mask) and falls back to RMBG-2.0 (saliency cutout) per detected region for clean transparent foregrounds. Without a Replicate key, layers are plain rectangle crops. Neither key is saved into templates.
