Free crochet pattern checker: find the mistake before you start

Craftuary's free crochet pattern checker counts the stitches in every round of a written pattern (US terms) and shows which printed stitch counts match, which don't, and which lines it couldn't read. Paste the pattern, and in a few seconds you'll know whether it adds up, instead of finding out 40 rounds in. Pattern in UK terms (dc, htr, tr)? Convert it to US terms first.

What you get back, for example:
✓ Rnd 3: (sc, inc) x 6 makes 18, the pattern says (18)
✗ Rnd 4: (2 sc, inc) x 6 makes 24, but the pattern says (23). One of the two is a mistake.
One free check a day with a free account.

How it works: the checker reads written patterns in US crochet terms and does the stitch arithmetic round by round, the same way you would with a pencil. When a line is worded in a way it can't read for certain, it says so instead of guessing. It does not read charts or photos. Your pattern is checked and discarded, never stored.
