Mercer (formerly Cala) vs Super T

Generate garment and product concepts from text prompts or reference imagery, refine them with text-to-image, product variations and an AI Paintbrush editing tool.

Train a custom fine-tuned model on your own collection and inspiration imagery so new development stays on-brand and visually consistent.

Store, organize and update images, video, 3D files and spreadsheets in one place instead of tracking them across drives and inboxes.

Comment and add measurements directly on files, assign tasks with notifications, and keep production timelines on track with checklists and reviews.

Describe your idea in ordinary language — a phrase, a theme, a style reference — and the generator produces full-colour T-shirt artwork, with no illustration or design software required.

A 'hot designs' feed shows recently generated shirts alongside the exact prompts behind them, so you can buy a finished design or copy a prompt as a starting point for your own.

Preview the artwork on apparel and check a published size chart with length, width and sleeve measurements for every size from S through 3XL before ordering.

Super T prints and ships the finished shirt through its production and worldwide delivery network, emailing tracking and an estimated delivery time after payment.
