Capsulla is still in development and opens soon.

Pasting into AI tools

The assistant is useful. The paste is the problem.

Banning AI assistants moves the work to someone's phone. Capsulla takes the other route: the tools stay, and what people put into them is checked in the browser, at the moment of the paste.

Clipboard rules
[AWS_KEY]Access keysBlock
[CARD]Card numbersMask
[EMAIL]Email addressesAllow
Three answers to the same paste, chosen per rule.
At the moment of the paste

Checked before it lands in the page

A rule can block the paste outright, warn the person and let them decide, or mask the sensitive part so the rest of the paste still works — a support agent can still ask about an order without the card number travelling with it.

  • Typing is covered too, because somebody who cannot paste will type it out instead.
  • The check runs on the device, so it makes no difference which assistant it is, or whether it launched last week.
How clipboard rules work
The tool you do allow

Whitelist the assistant you chose

Most companies end up approving one AI tool and tolerating the rest. Put the approved one on the whitelist and Capsulla stays out of it entirely — nothing checked, nothing recorded — while everything else stays under the rules.

Whitelisted domains
assistant.yourcompany.comcrm.yourcompany.com

Nothing checked, nothing recorded, on those hosts.

The assistant you approved is not the one you are worried about.
Afterwards

A week of this tells you what to do next

Every match leaves a row: which rule, which action, which site, whose browser. Not the text. That log is what turns “people are probably pasting things” into a conversation with names and numbers in it.

What the log holds

Worth knowing

  • Capsulla protects web interfaces in Chrome on managed browsers. A desktop app or a phone is outside it, and we would rather say so than let you find out later.
  • The matched text never leaves the device, so the console cannot show you what somebody pasted — only that a rule matched.

Other things people move

Stop the next leak before it leaves the browser.

Try it free for 14 days, no card needed. Start with one team and see what Capsulla catches in the first week.
