COMPARISON
Piuma vs. Antinote
Both cost around $5, both live as a notepad on the Mac. The difference is philosophy: Antinote is built for quick, throwaway notes with a built-in calculator. Piuma is built for text that comes back — and that needs to arrive clean from ChatGPT & co.
| Feature | Antinote | Piuma |
|---|---|---|
| Price | $5 once (trial available) | $4.99 once (Pro) |
| Philosophy | Throwaway notes, cleared quickly | Persists; with Pro the time machine keeps earlier states |
| Calculating in text | Yes — core feature | Yes (Pro), basic arithmetic: select + right-click or “=” (opt-in) |
| Markdown views | No — plain text with simple Markdown syntax | Yes — Plain / Markdown / Formatted; Markdown and Formatted editable |
| Cleaning up formatting from ChatGPT & co. | Yes — pasting strips formatting, bullets and indentation | Yes — core feature |
| Sync across devices | Yes, optional via your own iCloud (end-to-end encrypted) | Yes (Pro), via your own iCloud (up to 1 MB of text) |
| Keywords / timers | Yes — keywords at the start of a note (e.g. “timer”: stopwatch, countdown, pomodoro) | No — deliberately not built |
| Platform | Mac (iOS in development, per the vendor) | Mac |
Honest verdict
If you want notes you deliberately throw away, and a calculator built into the notepad, Antinote ($5) is built for exactly that. If you want a notepad that shows Markdown as readable text, detoxes links, and keeps earlier states (Pro), Piuma ($4.99) is the alternative.
