Guide reviewed 23 September 2026. The live Chrome Web Store listing for TriageBox is 2.02. See the changelog for what shipped.
Desktop Chrome extension · Gmail, in your browser
Copy a Gmail verification code from the card
When the subject already contains exactly one sign-in code, TriageBox puts that code on the card and a Copy code button next to it. Spaces and dashes come off. No AI key for that path. No TriageBox mailbox server.
This is not an SMS reader, and it is not a phishing checker, waiting for reply, bulk unsubscribe, or deleting old emails.
Free on the Chrome Web Store · no account · desktop Chrome only
Gmail already shows the mail
Open the message if you want the thread. Use TriageBox if the digits are the whole job.
Gmail will open the email. That is enough, and it is free. TriageBox is for the narrower chore: the subject already says the code, and you want it on the clipboard without opening Gmail. The card replaces that subject line with the code itself. A sign-in code is treated as a chore, not as spam. Review Google's sign-in and permission prompts before connecting.
Same mailbox, different job
Opening Gmail vs TriageBox Copy code
Facts from the current extension documentation for TriageBox and from how the popup actually copies a code. No invented ratings.
| What you need | Gmail | TriageBox |
|---|---|---|
| The digits, on the clipboard | Open the thread, select the code, copy | Copy code on the card. Spaces and dashes stripped, so a field that rejects “123 456” still gets the characters. |
| When the button appears | Always, once you have opened the mail | Immediately if the subject has exactly one code. If the subject only names a code, the digits wait until that message is read and the same characters are found in the body. |
| Several numbers in the subject | You can see which one is the code | No Copy code from the subject. Guessing the wrong token is worse than no button. |
| SMS or authenticator codes | Not in Gmail | Not read. This is Gmail only. |
| A code you did not request | The mail is still just mail | Don’t enter it. The card’s note is to change that account’s password. This page is not a phishing verdict — that is the phishing checker. |
| On your phone | Gmail app | Desktop Chrome only |

How Copy code actually runs
Add to Chrome installs this product. These are the steps on a signed-in Gmail account you are authorised to use.
- Install and connect Gmail. Desktop Chrome or another Chromium browser. Google shows the account and permissions you are authorizing; verification warnings depend on the release and account. No TriageBox account.
- Leave the code email in the queue. TriageBox looks at the subject for wording like verification code, sign-in code, one-time code, OTP, and the common French, Spanish, German, and Italian equivalents.
- One candidate, or nothing. A single 4–8 digit number that is not a year, or one mixed letter-and-digit token. Two numbers means no button from the subject.
- Copy code. The clipboard gets the characters only. Paste it yourself into the site that asked. If you did not request the code, do not enter it.
The code is the subject line
The row shows the code large, not a subject that only says a code exists. Gmail’s own subject stays on hover.
Copy, don’t guess
Exactly one candidate from the subject, or the same characters later found in the body. Never a made-up code.
Not SMS, not a password manager
Your Gmail, this computer, the clipboard. Nothing is typed into the other site for you.
Phishing is a different page
Sender checks live on Gmail phishing checker. This page does not call a verification email spam.
The digits, then you paste them
Copy the code. Don’t open Gmail for a subject that already has it.
Desktop Chrome extension. No TriageBox account. Data stays in your browser.
Limits, stated
What this page does not claim
- It does not read SMS, WhatsApp, or an authenticator app.
- It does not type the code into the site that asked, and it does not bypass 2FA.
- It does not invent a code. Several numbers in the subject means no Copy code from the subject.
- It does not copy a code from Sent mail you wrote. That code is someone else’s.
- It does not appear instantly when the code is only in the body. That waits until the message is read and the same characters are found there.
- It does not decide the mail is safe. A code you did not request should not be entered. Sender checks are Gmail phishing checker.
- It does not list unanswered sent mail. That is Gmail waiting for reply.
- It does not unsubscribe senders. That is bulk unsubscribe Gmail.
- It does not delete old mail. That is delete old emails in Gmail.
- It does not run on your phone.
- It does not send the code through a TriageBox server.
- It is not for anyone else’s mailbox.
Quick answers
Gmail verification code
How do I copy a Gmail verification code without opening the email?
TriageBox is a Chrome extension. When a message in your own Gmail is a sign-in or verification code and the subject already contains exactly one code, the card shows that code large, with a Copy code button. Copy strips spaces and dashes. This does not read SMS, and it does not type the code into another site for you.
Does copying the code need an AI key?
No, when the code is already in the subject and there is exactly one candidate: a single 4 to 8 digit number that is not a year, or one mixed letter-and-digit token. If the subject only says a code exists, TriageBox waits until that message is read and the same characters are found in the body. It will not invent a code it did not find. A wrong clipboard guess is worse than no button, so several numbers in the subject means no Copy code from the subject.
Is this the Gmail phishing checker?
No. The phishing checker reads Gmail’s SPF, DKIM and DMARC plus reply path and attachments on the card you are looking at. This page is only the copy-the-code chore. A code you did not request is still a reason not to enter it, and to change that account’s password. Use Gmail phishing checker for that job, Gmail waiting for reply for unanswered sent mail, bulk unsubscribe Gmail to stop lists, and delete old emails in Gmail to clear by age.
Does my mail go through a TriageBox server?
No. There is no TriageBox mailbox backend. The separate public support service counts anonymous likes; it receives no Gmail content. Processing runs in your browser; Gmail data is not sent to the publisher. The code is copied to your clipboard on this computer.
