Do I need to know how to code to build a custom mode?

No. You describe the workflow in plain English — the Sleeve Studio mobile app (ships before your sleeve on a small monthly subscription) generates a valid mode from your voice or text, and you send it to the sleeve over Bluetooth with no programming required. Today's live browser preview at garmentgui.com/studio/ lets you browse all 50 mode profiles, preview them on the simulated 8x32 canvas, or use the Step 1 prompt template and send v1 profiles over Web Bluetooth.

Can I keep multiple custom modes and switch between them?

Yes. Sleeve Studio stores your named profiles and the sleeve can hold several, so you can load a different saved mode over Bluetooth—double-tap Pad 3 in this profile cycles to the next one.

Will my custom mode keep working if a website goes offline?

The rules you send are stored on the sleeve's controller and run locally, so your mode keeps playing on the 8×32 matrix whether or not any app or site is open; Sleeve Studio is only needed when you want to author or send a new profile.

Mode #51 is yours: describe any 5-pad, 8×32 LED workflow in plain English, preview it, and send it over Bluetooth in about 30 seconds — $199.

Why Every Other Wearable Ships a Fixed Menu You Cannot Change

No locked menus: Most wearables freeze the handful of gestures they shipped; here you author the rules and own the profile.
Only limited by your words: The sleeve does whatever workflow you can describe in a sentence — and keeps running it offline.
Peer-reviewed textile roots, shipping hardware: The Oct 2026 NUS Nature paper reported a lab-prototype fibre touchscreen (not for sale) that inspired the category; our shipping $199 sleeve uses 5 sewn conductive-fabric pads and a removable 8×32 LED core for gentle cold hand-washing.
