cloakup
A private place to chat with AI. Personal and business details are removed on your own device before your message is ever sent — so the AI helps you without seeing who it's about.
Private by default
Emails, phone numbers, card numbers and common personal names are swapped for stand-ins on your device before sending.
Just chat normally
No setup, no jargon. Ask a question the way you'd ask a colleague — the answer comes back with the real details filled in.
See the proof
Every answer comes with a receipt you can check yourself — proof the private bits never left your computer.
Structured details (emails, phone numbers, cards, IBANs, ID and card numbers) are removed reliably, on your device. Common personal names are caught too, using an on-device name list — but this part is best-effort, not perfect: an uncommon or non-dictionary name, or a name in a non-Latin script, can still slip through. Always review anything highly sensitive before sending.
