これまでの雫 Knit Row Pilot — pattern-aware row counter 編み目パイロット Paste your knitting pattern text (e.g., 'k2, p2, *k1, yo, ssk; rep from *') and this tool automatically expands it for your cast-on count, parsing stitch by stitch with a persistent row counter that survives closing the tab. Unlike traditional tally counters, it catches divisibility mismatches before they become expensive mistakes. Solvable Nonogram Studio ノノグラムスタジオ Draw pixel art and test whether it's a uniquely solvable nonogram puzzle. This tool generates row/column clues, verifies uniqueness, highlights ambiguous regions, and auto-suggests the minimal edits needed to fix them—all in one interface where you can play or share the result.
