Why this matters

A pasted document is a leaked document.

Once a contract, deal memo or client file lands in ChatGPT, Claude or Gemini, you have no recall, no audit trail, and no way to prove it stayed confidential.

The exposure
It doesn't stay in your chat.
Most AI providers retain prompts to train, debug, or moderate. Free tiers in particular can replay your text inside another user's session.
The obligation
Your NDAs still bind you.
Confidentiality clauses, client privilege, GDPR, and professional duty don't pause because the tool is ‘AI’. A leaked clause is still a breach.
The blind spot
You can't see the breach.
There's no log of who pasted what, where, when. By the time a client asks, the trail is gone — and the burden of proof is on you.
80% of employees use AI tools their company hasn't sanctioned.
38% have already pasted sensitive data into one without approval.
$4.2M average cost of a shadow-AI data breach in 2025.

Bound to the document.
Not to a policy.

Most tools block types of data — credit cards, secrets, anything that looks like PII. Arvane binds protection to the exact file you sent, to the exact person you sent it to, for as long as you want.
