The best crochet pattern checkers and AI designers
To check a pattern you already have, CrochetPatternGen is free and unlimited, and Craftuary adds the fix for each flagged round on Pro. To get a new amigurumi pattern from an idea or photo, try Craftuary's Designer or Crochets.site. To write your own and watch it build, use Crochet 3D or AmiLab.

CrochetPatternGen
Free browser checker that recomputes each round and shows the arithmetic. It also has an amigurumi generator with a 3D preview, built from shapes you arrange.

Craftuary (our site)
A checker that reads a written US-terms pattern round by round and flags counts that don't match and lines it could not read. The Designer writes an original amigurumi pattern from a sentence or photo.
Suits: Getting a pattern from an idea or photo, then seeing the fix for a flagged round. Watch out for: The free plan is one check a day. The Designer is amigurumi only.
Crochet 3D
A round-by-round editor with live 3D preview and stitch count checks as you type.
Suits: Designers writing their own patterns and watching them take shape. Watch out for: You write the pattern yourself. Multi-piece projects start on the Designer plan.
AmiLab
Sculpt a shape in 3D and it writes the round-by-round instructions.
Suits: People who think in shapes more than in stitches. Watch out for: Paid prices were not published when we checked.
Crochets.site
Describe an idea and an AI writes a pattern with row-by-row instructions, stitch counts and a 3D preview.
Suits: Quick AI drafts of many item types. Watch out for: We could not confirm its prices.
CrochetPop
Turns a photo into a chart with row-by-row instructions for filet, granny, C2C, pixel and amigurumi. It says its patterns come from algorithms and not a language model.
Suits: Photo to chart projects. Watch out for: It makes charts from photos. It is not a checker for a pattern you already have.
Stitch Fiddle
A long-running chart editor for crochet, knitting, cross stitch and more.
Suits: Colorwork and chart design across crafts. Watch out for: It edits charts. It does not check a written pattern's counts.
How did we compare them?
We read each tool's own site and pricing page on 2026-11-09, without an account. We did not run the same test pattern through every tool, so this page compares what each one offers and does not score accuracy. A tool we could not confirm was left out.
Questions
Is there a free tool that checks crochet stitch counts?
Yes. CrochetPatternGen's checker is free and unlimited in your browser, and Craftuary's Checker gives one free check a day. Both recount each round and compare it with the printed number.
Can ChatGPT check a crochet pattern?
It can try, but a chatbot can miscount. A checker built for this recomputes each round by rule, so use one for the arithmetic and read the pattern yourself for everything else.
Does a passing check mean a pattern will work?
No. A check shows the counts agree. It can't tell you whether the shape, the sizing or the assembly will turn out as pictured.
