Review and make

Read through the generated pattern, check your gauge and adjust the details that matter to your project.

Built for crochet — still made with your judgement

purlJam starts with structured craft templates rather than a blank prompt. It uses the project details you provide to build the materials, gauge, stitch counts, shaping and instructions. Yarn, tension and fit vary from maker to maker, so read the pattern before starting and make a swatch where sizing matters.

Frequently asked questions

Is the crochet pattern generator free?

You can create patterns with a free purlJam account. Standard and Pro plans add more monthly generations and extra creative tools.

Can an AI crochet generator make an accurate pattern?

purlJam uses structured templates and maths checks to make patterns more consistent, but yarn, gauge and fit vary. Read the pattern first and make a swatch where sizing matters.

Can I use UK or US crochet terms?

Yes. Choose UK or US terminology before generation. purlJam keeps stitch names and abbreviations consistent with that choice.

What kinds of crochet patterns can I create?

You can describe amigurumi, hats, scarves, blankets, bags, cardigans, tops, shawls, home accessories and other custom projects.

Can I use my own yarn, measurements or colours?

Yes. Include them in the description and choose a yarn weight. For fitted garments, check the finished measurements and gauge before starting.

Can I create a crochet pattern from an image?

Standard and Pro members can attach a reference image to guide a pattern. Only upload images you own or have permission to use.
