Everything happens in this tab. Your text and the key are never uploaded or stored, unless you save the key yourself.
How it works
Each detail found in your text is swapped for a label, and the same value always gets the same label, so the AI can still follow who did what: "[PERSON_1] emailed [EMAIL_1] about order [NUMBER_1]". The key, a list of labels and the real values, stays in this tab. When you paste the AI's reply back, every label it used is replaced with the real value again.
Keeping the key
The key disappears when you close or reload the tab. To finish later or to hide a follow-up message with the same labels, choose Save key; it downloads a small file to your device. Open it here next time and new details continue the numbering, so [PERSON_1] stays the same person. Keep that file private: it contains the real values.
Questions
What if the AI changes a label?
With the rewrite option on, labels written a little differently, such as [person 1], [PERSON 1] or PERSON_1, are restored too. Labels that aren't in the key are left as they are and listed, so nothing is guessed.
Will it find every name?
Email addresses, phone numbers, card and account numbers, ID numbers, IP addresses, API keys and long numbers are found by their patterns. Names and company names have no fixed pattern, so add them to the list. Always read the safe text before pasting it.
Does the AI see anything private?
Only what's left in the safe text. The labels carry no information about the real values.
How is this different from Redact text?
Redact text removes details for good. This tool keeps a key so you can put them back into the answer you get.
