AI Nail Design Preview: See the Manicure on Your Own Hand (2026)

The salon-trip regret loop

Nail decisions are weirdly high-stakes for a small thing. You commit two weeks to a color you saw on TikTok; ten minutes in, the tech is already painting the second hand and you realize the shade reads completely wrong against your skin. Or you ask for "kind of an almond, but not too pointy" and end up with stilettos.

AI nail design preview removes the loop. You see the exact manicure on your exact hand, before the polish bottle is open.

What the AI is doing

The model receives your hand photo and four picker values: shape, color, design, finish. It treats everything in the photo except the nail beds as immutable — your skin tone, knuckle creases, ring, lighting, and background all stay exactly as captured. Inside the nail beds it renders fresh polish that respects:

• Shape geometry. A square nail isn't an almond with a flat tip — it has crisp corners and the right wall angle. The shape picker actually changes the nail outline, not just the paint color.
• Color physics. Glossy nail enamel reflects light off the curve of the nail; the AI renders specular highlights based on the photo's existing light direction. Matte and chrome finishes apply different reflectance models, so a matte black reads matte and a chrome silver mirror-reflects.
• Design layout. A French tip is rendered as a curve following the natural smile-line of the nail bed. Glitter accent goes on one finger only (typically the ring) so the result looks like an actual salon decision, not a wallpaper.

The four axes

| Axis | Options | Why it's a separate picker | |---|---|---| | Shape | oval, almond, square, squoval, coffin, stiletto | Most consequential. Different shapes lengthen or shorten the visual proportion of the hand. | | Color | 14 (nude → milky white → red → burgundy → soft pink → hot pink → coral → lavender → sage → navy → black → chrome silver → gold → French white) | The single biggest source of regret. Free to A/B. | | Design | plain, French, glitter accent, marble, minimal line, floral art | Personality layer. "Plain" with a strong color often reads more polished than busy art. | | Finish | glossy, matte, chrome | Changes the entire mood. Same red, glossy vs matte = completely different. |

Mixing freely matters. A coffin shape + sage green + marble + matte is a specific manicure that no one preset captures — and it's two seconds to render the preview.

Reading the result

A few things to look at when the preview lands:

• Hand-color contrast. Does the shade pop or disappear against your skin? Sage green flatters cool undertones; warm corals flatter warm. The preview is the cheapest way to test.
• Length proportion. Square nails on small hands can read stubby; almonds elongate. The shape picker tells you instantly.
• Daily-life fit. Stilettos look stunning in the preview; they also break against keyboards. Your call — but having the visual is what makes the call honest.

How it fits the rest of the app

Nails sit in the same try-on family as hairstyle, makeup, bandana, and outfit. The five studios share one design principle: see it on you, then decide. The free tier covers nails, hair, and outfit (one preview per day each). Makeup and bandana are Premium because their per-render cost on the AI side is meaningfully higher.
