Show HN: Taiyaki – AI-generated 3D jewelry from photos and sketches

Hey HN! I’m Elena, one of the co-founders of Taiyaki. My co-founder and I are both ex-Stanford mechanical engineers who worked on consumer electronics (iPads) and materials at Apple.

We built Taiyaki because most “custom” product platforms stall at 2D (like Etsy) or require complex CAD software. So we created a new pipeline: upload a photo, sketch, or idea, and we turn it into a 3D jewelry design in seconds, then make it in sterling silver, gold vermeil, or 14k gold.

We design with manufacturing in mind: things like minimum wall thickness, castability, and engraving depth are all baked into the output so the pieces can actually be made.

Would love feedback. Happy to answer questions!
