Zilch currently serves the owner's accounts and invited testers. This website provides product, privacy and support information. It does not provide access to anyone's mailbox or offer public account registration.

Google sign-in lets the installed app connect the Gmail account you choose. A browser connects separately through a private pairing flow. Optional AI processing requires its own sharing choice in the app.
