What Tricolab does

🧶

Hands-free counter

One very big + button, a screen that stays on, and your voice: say "next" or "back" without putting your needles down.

📖

A pattern that keeps your place

Import a PDF, photograph a paper pattern or paste its text. Your current line is highlighted and abbreviations are explained in plain words.

🧢

36 original patterns

Six styles: Classic, Modern, Rustic, Emoticon, Crop circle and Clothing. A drawing of the finished item, a measured schematic and sizes that recalculate the instructions.

🛸

Motif generator

30 chart motifs — crop circles, fishing, construction, leaves, racing, knight — in your size and colours, with the rows written out automatically.

🧪

The Lab

Step-by-step techniques, materials, chart examples, an abbreviation dictionary and calculators for gauge, sizing and yarn.

🎀

Share and stay motivated

A finished-project card to share, a monthly challenge, badges and your year in review.

👗

Clothing, from S to 2XL

Sweater, hooded cardigan, jacket, sleeveless vest, skirt, headrest cover and car seat pad, with optional body fit.

🕶️

Your piece in 3D and augmented reality

See it at real size on your table or wall. While you knit, finished rows show in colour and the rest faded.

📰

Magazine-style export

Turn a finished project into a magazine cover: big headline, pattern, yarn, time, rows and a QR code, ready to share.
