Zhisu

A design workspace for makers.

Zhisu helps small sewing and garment studios visualize designs, manage materials and estimate costs — all in one place. It's the first step in our mission, and it's currently in public preview.

Design workspace

Visualize designs · Manage materials · Estimate costs

Visualize. Organize. Estimate.

Three jobs most studios juggle across spreadsheets, scraps and screenshots — brought into one workspace.

Visualize designs

Turn an idea into something concrete and buildable before you cut a single piece.

Manage materials

Keep fabrics, trims and inventory organized so production stays on schedule.

Estimate costs

See a clear cost picture for every piece, so you can price your work with confidence.

Built for small studios

Zhisu is shaped around the way small teams actually work: a few people, limited time, and no appetite for enterprise software.

  • Small sewing and garment studios
  • Independent makers and pattern cutters
  • Studios moving their design work into the browser
