Before you begin
Stay curious.
Is Knotly free?
Yes, it is! We are currently in public beta and plan to keep Knotly free for the foreseeable future. We may introduce paid plans as we add more advanced tools and features, but the core functionality will remain free for all users.
Is Knotly suitable for beginners?
Yes! Knowing basic crochet stitches and how to read a pattern will help, but you can start small and learn as you go. Explore the gallery for examples, then follow the Quick Start guide to try your first project.
Do I need an account?
You can browse the gallery and explore example projects without signing in. To create and save your own projects, you will need to sign in.
Do I need to install anything?
No installation is required! Knotly runs in all modern browsers — just open your browser and start creating. You can also add Knotly to your home screen on iOS or Android to use it as a standalone app, or install it as a Progressive Web App (PWA) through your desktop browser.
Can Knotly catch mistakes in my pattern?
Yes. Knotly can flag syntax errors and stitch-count problems as you edit while the 3D preview helps you identify unexpected shaping issues. Previewing small sections as you work is usually a good way to detect issues early.
Can I use Knotly to test AI-generated patterns?
Yes, absolutely! AI-generated patterns can be frustrating because they often contain errors. Knotly helps you visualize and test them in 3D before you pick up your yarn, so you can spend less time unraveling and redoing your work.
Which crochet notation systems does Knotly support?
Knotly supports U.S. crochet terminology and XVA notation. Choose whichever feels more familiar. You can also use the built-in notation controls to convert between the two.
Will my finished project look exactly like the preview?
Yes, most likely so, but with some variations due to yarn type, hook size, tension, and individual technique.
