A minimal, privacy-focused notepad for quick math, currency conversions, and everyday calculations. Just type naturally and get instant results.
Write “Rent: $1,200 + Utilities: $150” and type “sum” to get the total. Convert currencies with live rates (”$500 in EUR”), handle percentages naturally (“20% off $80”), do date math (“christmas - 30 days”), or convert units (“5 km to miles”).
Features include multi-tab support, spotlight search (⌘K), focus mode, per-note themes, and variables for reusable values. Everything runs locally in your browser—no accounts, no tracking, no server-side processing.
