BetaDrawing symbol charts by hand or in illustration software takes hours, phone apps are cramped, and you always end up with a chart and no written pattern, or the other way round.
Draw the chart in your browser with standard US symbols, in rows or in real rounds, and the written instructions are generated from it, with each row’s stitch count checked against the one below.

Symbol charts come in two kinds: rows, and real rounds where every ring has its own stitch count. This real screenshot shows a flat circle in single crochet, with the written rounds generated beside it and the chart check confirming every count.

A symbol chart in rows, or in the round with your number of rounds and first-round stitches, or start from a flat circle.
Chains, slip stitches, sc, hdc, dc, tr, increases, decreases, popcorns, puffs, bobbles and post stitches. Mark repeats with a selection.
Rows and rounds are written from the chart, like “Rnd 3: (sc, inc) x 6 [18]”, with repeats as “*…*, rep from * to *”.
Most chart tools only draw grids, so doilies, mandalas and amigurumi rounds get squeezed into squares. Here a round chart is drawn as rings, each with its own stitch count, spaced evenly around the circle.
Because the chart knows which stitch sits where, the written pattern comes from it rather than being typed separately, so the two can’t drift apart. The chart check compares each row or round with the one below and tells you when it needs more or fewer stitches, and by how many.
Symbols look like the stitch: a chain is an oval, a slip stitch a dot, single crochet an X or plus, and taller stitches are posts with a crossbar per yarn-over. Increases fan out from a point; decreases meet at the top.
Rows are read from the side you start, alternating each row (the same as in the chart maker’s colorwork charts); rounds are read counterclockwise from the center for right-handed crocheters. If a round chart ruffles in real life you are adding too many stitches per round; if it cups, too few. More tools are on the crochet tools page.
Yes, for rows and rounds, including repeats and the stitch count at the end of each line.
Yes. Use the in-the-round chart type: each ring is one round, so the chart looks like the finished piece.
Yes. Each row or round is compared with the one below, and mismatches are flagged with how many stitches you are over or short.
