Client data doesn't belong in ChatGPT.
PasteLens warns you the moment secrets or client data are about to be pasted into an AI assistant or web app. Everything runs on your device, and nothing you paste ever leaves your browser.
Works across the major AI tools, including ChatGPT, Claude, Gemini, Copilot, Perplexity, Grok, Meta AI, DeepSeek and Mistral Le Chat, in Chrome, Edge and Brave, with Firefox coming.

01
Why this matters
The risk is already in your browser.
Your team is almost certainly pasting sensitive data into AI tools already. For a regulated firm, a single paste can become a reportable breach.
Client emails, case notes, financial records, credentials and source code get pasted into chatbots and web apps that sit outside your control. Once it leaves the browser you cannot pull it back, and you may never know it happened. For firms bound by GDPR, HIPAA, CCPA or DPDP that is not just risky, it is a compliance failure that can trigger investigations, mandatory breach notifications and heavy fines. PasteLens stops the paste before it happens, on the device, so the data never leaves in the first place.

02
One paste is all it takes.
Staff at careful firms paste client emails, case notes and financials into AI assistants because it's fast. One pasted secret or client record can become a reportable incident. Written policies don't stop muscle memory. Tooling does.
Confidential by obligation
law, healthcare and finance firms owe their clients a duty of care, and that includes their data.
Invisible until it happens
a risky paste doesn't announce itself. No trace, no warning, until it's a problem.
Policy ≠ protection
a line in the handbook can't catch a paste in the moment. Software can.
