Koiden is the product-development workspace for apparel and fashion brands. Styles, tech packs, fabrics, suppliers and deadlines usually live in scattered spreadsheets, chat threads and folders. Koiden brings them together in one clean library, organized by season. TECH PACKS, DONE FOR YOU Fill in the details once and Koiden produces clean, print-ready tech pack PDFs: header info, colorways and quantities, fabrics, trims, secondary processes and size charts with grading. Each tech pack is generated in English, Traditional Chinese and Simplified Chinese, ready to send to your factory. MARK UP EVERY DETAIL Add custom pages for washes, embroidery or prints, then circle an area, point to a stitch, add dimension lines and text labels right on the page. NEVER MISS A DEADLINE Every step from tech pack to pattern and sample, bulk production, shipping and delivery is laid out on one calendar. Overdue items stand out instantly, and you can add your own events like photo shoots. EVERY SEASON AT A GLANCE A dashboard shows total spend, style status, styles per category and colors in use, for one season or all of them. BUILT FOR THE WHOLE DEVELOPMENT CYCLE - Supplier directory, organized by category - Base patterns you can reuse as size-chart templates - Cross-season fabric library with color swatches - Sampling log and cost estimation for every style - Import photos, design files, patterns and care labels into each style's folder YOUR FILES, YOUR FOLDER Koiden stores everything in a folder you choose, on your Mac, in iCloud Drive or on a shared drive. Open it in Finder anytime, hand it to a factory, or share it with your team. WORKS ACROSS YOUR DEVICES Available on Mac, iPad, iPhone and Apple Vision Pro.
