We've all been there — mid-project and the numbers don't add up

The yarn you love is discontinued. You found something beautiful but it's a completely different weight. You want to use what's in your stash. All of these are the same problem: gauge maths, applied to every single stitch count.

Most of us either skip it (and frog on row 40), spend forever with a calculator, or post on Ravelry and hope someone answers before we lose momentum. There has to be a better way.

Tools that actually understand how crafters think

🔢

Zero AI guessing in the maths

A deterministic JavaScript calculator computes every ratio to 4 decimal places before AI touches your pattern. The AI writes the instructions. The code does the numbers. Every time.

📐

Measurement-first sizing

Enter your bust, body length, and arm length. StitchPlus reads the size table and tells you which size to make — then calculates every stitch count precisely for your measurements and ease preference.

📷

Photo to pattern

See a jumper you love in a store? Photograph it. AI identifies the construction, neckline, sleeve type, and stitch pattern — then generates a full pattern sized to your measurements.

Real makers, real projects, zero frogging

★★★★★

"I had 8 skeins of Drops Karisma that didn't match anything on Ravelry. Scanned the pattern, entered my gauge, got the full recalculated instructions in 2 minutes. I would have given up on this project."

"As a pattern designer I used to spend hours answering 'can I use X yarn instead?' Now I put the widget in every pattern PDF. My customers self-serve and my inbox is quiet."
