Mask It Before It Goes Into an AI
"Is it okay to paste this document into ChatGPT?" — that hesitation is the signal.
Swap names, phone numbers and company names for pseudonym tokens before you paste,
then turn the AI's reply back into the originals. It all happens inside your browser.
"Please review the contract. Attn: Alex Hong, Garim Trading Inc. Contact: +1 555-000-0000."
"Please review the contract. Attn: [NAME_1], [COMPANY_1] Contact: [PHONE_INTL_1]."
* The AI only ever sees the line below. Tokens in its reply are restored back to the originals. Dashed (?) tokens are candidates — not auto-confirmed.
* This example uses a labeled format ("Attn: …") because English name and company detection needs a label or a legal suffix like "Inc." to fire — a plain, label-free sentence won't be flagged the same way. Korean text is detected more broadly.
When you need this
What you type into an AI service is handled under that service's own policy.
Not handing over the original in the first place is the surest defense.
Getting a contract or report reviewed
Swap out a phone number, or a labeled name and company (a legal suffix like 'Inc.' or a label like 'Attn:' helps English text get picked up),
and AI still reads the document's structure and clauses.
Polishing a reply to a customer
Draft the reply with the customer's name and contact details masked,
then restore them inside your browser before you send it.
Analyzing logs or data
Clean up a log full of emails, IPs and internal URLs
before you paste it in — the analysis quality doesn't change.
Deleting breaks context. Replacing keeps it.
Simply deleting personal information makes the AI lose track of how the document relates to itself.
A pseudonym token like [NAME_1] or [COMPANY_1] keeps the "who did what with whom" structure while hiding identity,
so summarizing, translating and reviewing keep their quality.
A token in the reply becomes the original again using a mapping table that only exists in this browser.
How to mask, then paste
Keep using the AI you already use — just add one step.
- Step 1
Paste your text
Paste the document or prompt you're about to send an AI
into Garimi's workspace first. - Step 2
Review and swap
Review what was found — phone numbers, emails and IDs are caught the same way in English and Korean text, but English name and company detection needs a label ("Attn:", "Contact:") or a legal suffix ("Inc.") to fire, while Korean prose is read more broadly.
Then swap what you approve for pseudonym tokens like [NAME_1]. - Step 3
Paste into the AI
Copy the replaced text and paste it as usual
into ChatGPT, Claude or whichever AI you use. - Step 4
Restore the reply
Paste the AI's reply back into Garimi
and the tokens turn back into the originals, using the mapping table kept in this browser.
Frequently asked questions
Doesn't masking personal information hurt the quality of the AI's answer?
Tokens like [NAME_1] and [COMPANY_1] preserve sentence structure and relationships, so summarizing, translating and reviewing barely notice the difference.
The less "who this is" matters and the more "what this is" matters, the more true that is.
Does this catch names and companies in plain English text as well as it does in Korean?
Not yet, and it's worth knowing before you rely on it. Phone numbers, emails and ID-number patterns are found the same way in English and Korean.
But English name and company detection today only fires next to a label ("Attn:", "Contact:", "Name:") or a legal suffix ("Inc.", "Ltd.") — a plain sentence like "Alex Hong from Garim Trading called about the invoice" won't be flagged. Korean prose is read more broadly.
Review the result yourself before you paste it in, especially for English text with no labels.
Does Garimi send my text to the AI for me?
No. Garimi isn't connected to any AI service.
You copy the replaced text and paste it yourself, then bring the reply back and restore it yourself.
That means there is no path for the original text to leave Garimi at all.
What if the AI changes a token in its reply?
An exact token is restored automatically. A slightly altered one is shown as a candidate for you to confirm before it's restored.
An ambiguous one is left as-is rather than exposing the original automatically.
Where is the mapping table stored?
Only in this browser tab's memory.
It is never saved to a server, and it disappears if you close the tab or refresh — so finish restoring in the same tab.
