Calculator chat
Try one of these:
How it works
- Type your question in plain English — gauge, dimensions, yarn weight, whatever you have.
- AI picks the right Stitchsums calculator and extracts your inputs.
- The deterministic calculator runs the math — the AI never does arithmetic directly. You get the same answer every time for the same inputs.
- The answer card shows the worked explanation and links to the full calculator page.
What it can answer
Anything covered by the 23 Stitchsums calculators: cast-on counts, gauge conversion, yardage substitution, raglan shaping, hat decreases, yarn held together, stripe sequence yardage, and more. If the question needs a calculator we don’t have yet, the chat will say so.
Accuracy
Every answer is stamped “Verified by Stitchsums math” because the calculation runs through the same deterministic code as the individual calculator pages — not generated by the language model. Gauge-dependent answers assume your stated gauge; always measure from a washed, blocked swatch.
