The Tool

Not a chat wrapper. A patch design engine.

Three things separate us from a generic AI: production guidance baked into the model, a configurator that handles the technical decisions, and a direct line to manufacturing.

Generic AI chat

A pretty picture, then what?

Raw model output. No knowledge of thread density, real palettes, or stitch geometry. You email a vendor a screenshot and start over translating it into manufacturing.

PatchDesign.AI

A design that's manufacturable on day one.

Production constraints baked into every prompt. Configurator choices tune the output to the chosen material. Quote, review, and shipment in one flow.

1 · The model

Production guidance baked into the model

We don't ship raw Gemini output. The system prompt is crafted with manufacturing constraints so the design lands production-ready, not just visually appealing.

  • Thread-density limits for embroidered patches so designs don't request impossibly fine details.
  • Color palette restrictions — real thread colors, not arbitrary RGB.
  • Stitch-direction logic for shapes that read cleanly when sewn.
  • Edge handling and border thickness rules that keep the patch durable.
  • Backing-compatible content rules that match iron-on, velcro, or sew-on choices.
  • Output is design-ready for manufacturing, not just a render.
2 · The interface

The configurator handles the technical decisions

Generic AI chats make you describe everything in words — and skip the technical decisions altogether. The configurator surfaces the choices that matter and feeds each one back into the prompt.

  • Patch type: embroidered, PVC, iron-on, velcro, woven, chenille — each tunes the prompt.
  • Size, shape, quantity: set up front so the design respects the canvas.
  • Backing & finish: hot-cut vs. merrowed border, sew-on vs. velcro, glow-in-the-dark thread.
  • Material reality: each choice tunes the AI's prompt context.
  • Brand auto-detection: type "YMCA" or "Boy Scouts" and we include the official mark, current year, and approved colors.
  • Live preview: revisions show immediately, no round-tripping with a vendor.
3 · The pipeline

Direct line to production

The design isn't an end product — it's the first step. Skip the screenshot-and-email-a-vendor stage entirely.

Design → review by our human team → vetted manufacturers → patches shipped. The quote your vendor receives includes the design image, sampled colors (hex + thread names), and the full conversation history so the manufacturer sees how the design evolved — not just the final pixels.

4 · Try On

See it before you commit

Real product mockups with proportional patch overlay so the patch size on the product matches what you'd actually receive.

  • Real garments: jacket, big bag, t-shirt back, hat, small bag.
  • Proportional sizing: a 3" patch reads as 3", not full-frame.
  • Pick the right size first: avoid the "it arrived too small" surprise.
  • Surface-aware: jacket, big bag, and back-shirt only show when the patch is large enough.
5 · The economics

Free AI design + free expert human review + free revisions

You only pay if you turn your design into physical patches. The free tier isn't crippled — it's the full tool. No watermarks, no credit card, no signup required to design.
