Safe Paste

Paste into an AI app without handing over the details it doesn’t need.

People paste emails, logs, invoices and customer records into AI chat apps and coding assistants all day. Most of it contains an address, a phone number or a key that the question never needed. Pocketry can swap those details for placeholders on the way in, and put them back when you copy the answer.

How it works

You copy something, open Pocketry, and paste into an AI app as usual.
Pocketry spots the emails, phone numbers, card numbers, bank accounts, ID numbers, keys, passwords written as “password: …”, login codes and long numbers it recognises, and swaps each for a placeholder such as [EMAIL_1]. The same value always gets the same placeholder, so the AI can still follow who is who.
A small note shows what was masked, for example “Masked 2 emails, 1 card number”, with buttons to replace the paste with the original or copy the original instead.
When you copy the AI’s answer back, a small panel offers a Restore button and the real details return in one click. You can also choose Restore from the entry’s right-click menu, or turn on “Restore automatically” in Settings under Privacy to skip the click. Restored text pastes with the real details, once, even into an app set to mask. It is saved in your history like any other entry, encrypted on your Mac. Restore automatically is off by default.

Screenshots too

When you paste a screenshot into an app with Safe Paste on, Pocketry reads the text in it on your Mac and covers the emails, numbers and keys it recognises with solid black boxes, then pastes the covered picture. If it finds nothing it tells you so, so you know to look. If the check fails, it doesn’t paste until you say so.

You decide where it applies

When text with private details is about to go into a supported AI app, it asks once: mask, or paste as is. Nothing is masked until you say yes. You can also pick any app in Settings, or hold ⌥ while pressing Return to paste masked in any app, including a web page.

What stays on your Mac

Masking text is pattern matching on your Mac. It uses no network connection. Reading the text in a screenshot uses the text recognition built into macOS, also on your Mac.
The list that remembers what each placeholder stands for lives in your Mac’s memory. It is never written to disk, never added to your history and never included in a problem report. It is forgotten after a few hours (you choose how many), when your Mac sleeps or locks, when the Touch ID lock closes, and when you quit.
What an AI app does with the text you paste is up to that app. Masking changes what it receives.

What it can’t do

Safe Paste finds what it has patterns for. Names are off by default. You can turn on “Also mask names” in Settings; it uses Apple’s language tools on your Mac, finds many but not all names, and can mask an everyday word that is also a name. Street addresses, company names and unusual secrets are still not recognised. Look at what you’re about to send. If you need it to catch more, tell us what it missed.
