Write plain text, get live results per line. English + Russian, units, live currency rates with crypto, percents, dates and timezones, bitwise ops, variables and sheet totals. Tauri 2 + TypeScript engine + CodeMirror 6; daily backups and a deleted-sheets bin. Inspired by Numi for macOS (numi.app); built from scratch for Windows.
