Deckname — Data anonymizer for Mac. It swaps names, companies, emails, and other personal details for placeholders like [PERSON_1] before you paste text into an AI chat. Get your answer, paste it back, and every placeholder turns into the original. Everything runs offline, so your data stays on your Mac.
Ask AI about a contract safely
Summarize meeting notes privately
Rewrite emails without sharing names
Hide client details in AI prompts
Deckname features
Protect, paste, restore
Three steps, no learning curve. Protect your text, send it to any AI assistant, then paste the answer back into Deckname to bring the real details home.
Catches the personal stuff
Deckname finds names, companies, places, email addresses, phone numbers, IBANs, card numbers, and IP addresses. Then it swaps them for neat placeholders.
You make the final call
Review every match before anything leaves your Mac. If something can stay visible, just uncheck it.
Favorites and custom terms
Give your boss or key clients their own placeholder, like [BOSS], so it stays the same every time. Add project code names, product names, or internal words too.
Quick access from the menu bar
Open the panel in a click, or use the shortcuts: ⌃⌥⌘D to protect and ⌃⌥⌘R to restore.
Private by design
Deckname works fully offline. The placeholder list lives in memory only, so nothing is stored once you’re done.
