How it works

Pasting a client email or a contract into an AI chatbot can put names, addresses and account numbers into someone else's system. ALIAS swaps those details for placeholders, using the same placeholder every time a name appears, so the masked text still makes sense. Send the masked version to the AI, paste its answer back, and ALIAS puts the real details back in. The key stays on your device.
