A crochet chart maker built for symbol diagrams

What it does

• Standard stitch symbols. Eleven symbols from the Craft Yarn Council set: chain, slip stitch, single crochet, half double, double, treble, dc2tog, dc3tog, a five-dc shell, picot and a magic ring.
• Two layouts, both first-class. In-the-round charts get concentric guide rings, numbered from the center out, and symbols that rotate to point outward the way real stitches lean. Row charts get numbered rows with optional direction arrows.
• Fill a round evenly. Say "round 3, 24 stitches" and the symbols distribute around the ring at the right spacing and the right angles. This is the tedious part of drawing a round chart by hand, and it is one click here.
• Group, rotate, mirror. Select a run of stitches, group it so it moves as one unit, then rotate it by a chosen number of degrees or mirror it horizontally or vertically.
• Radial repeat. Chart one wedge of a doily, select it, set a repeat count, and the wedge is copied around the center at exact angles. Eight wedges of a twelve-symbol wedge is one operation, not ninety-six placements.
• 100 levels of undo, and autosave. Every change is undoable, and your chart is saved to your own browser after each edit, so a closed tab is not a lost afternoon.
• Real project files. Save a chart as a small .chart.json file and reopen it later, on any machine, in any browser.
• Vector export. SVG for Illustrator, Affinity, Inkscape or Canva, and a true-vector PDF at real physical size. Both stay crisp at any zoom and at any print resolution.

What designers have been asking for

Two kinds of tool exist already, and neither covers symbol charts properly.

The grid tools — the ones built for colorwork, tapestry crochet and pixel charts — are good at what they do. But a grid of colored squares cannot express a doily. Stitches in the round are not on a grid, they radiate; symbols have to rotate; a shell is five posts sharing one foot, not five squares in a row.

The desktop symbol programs that could draw real diagrams are, for the most part, a decade or more without maintenance. Designers keep old machines running to use them, or lose access entirely when an operating system moves on. Software you install can be abandoned; a web page cannot be, in the same way.

So the requests that come up again and again in designer forums are pretty specific, and they are what this tool was built around: group a run of stitches and move it as one; rotate and mirror motifs instead of redrawing them; lay out genuinely circular charts rather than faking them; and export something that drops into a pattern PDF without a trip through a screenshot and an image editor.

What it does not do

Worth knowing before you spend an evening on it:

• The symbol set is eleven symbols. Post stitches, popcorns, bobbles, puff stitches and back-loop-only markers are not in it yet.
• It does not generate written pattern text from your chart, and it does not check your stitch counts for you. It is a drawing tool, not a pattern validator.
• It does not do colorwork or pixel grids. If you need a tapestry crochet chart, a grid tool is the right thing and this is not.
• It wants a real pointer. It works on a tablet, but placing symbols precisely is much easier with a mouse or trackpad on a desktop browser.

How to draw your first chart

1. Pick a layout. "In the round" for a doily, mandala, motif or granny square; "Rows" for a flat piece worked back and forth.
2. Set the rounds and spacing. Rounds are the concentric guide rings; spacing is how far apart they sit. You can change both later without losing work.
3. Fill round 1. Choose a symbol in the palette, set the round number and stitch count, and click "Fill round evenly". The symbols land at even angles, already rotated outward.
4. Draw one wedge of the next round. Place symbols by clicking on the canvas. Snapping to the guide rings keeps them tidy.
5. Repeat it around. Select the wedge, set the repeat count, press Repeat. The motif comes out symmetric because the math is doing it, not your eye.
6. Export. Turn the guide rings off if you do not want them in the finished chart, then download SVG or PDF.

Free and Pro

The whole editor is free: every symbol, both layouts, grouping, rotation, mirroring, radial repeat, undo, autosave and project files. Free exports cover charts up to 30 stitches and carry a small corner note.

Pro is $39, once. No subscription. It removes the stitch limit and the corner note, so exports are clean at any chart size, and it includes symbols and features added later. If it does not work out for you, there is a 14-day refund — see the terms.

Your work stays on your computer

The editor is a static web page. There is no account, no upload, and no server holding your designs — charts autosave into your own browser’s storage and project files save to your own disk. That is a deliberate design choice, and it is also why the tool keeps working offline once the page has loaded.
