thinking,
out loud,
privately.
Erys is a personal AI that runs entirely on your device. Nothing leaves your phone. No accounts, no cloud, no eavesdropping. Just a quiet companion for thinking, writing, and remembering - yours alone.
everything you need.
nothing you don't.
erys is designed to be powerful yet simple. advanced AI that anyone can use, with privacy that everyone deserves.
truly private
your AI runs entirely on your device. no server ever sees your conversations, your files, or your thoughts.
remembers everything
a personal brain that grows with you. it remembers what you tell it, learns your preferences, and connects your ideas.
sees and understands
show it photos, documents, receipts, or screenshots. on-device vision reads and understands everything you share.
effortless setup
download. open. done. no accounts, no configuration, no technical knowledge required. the simplest AI you'll ever use.
works offline
no wi-fi? no problem. your assistant is always available, anywhere you go. on a plane, in the countryside, underground.
sync across devices
optionally sync your brain across devices with end-to-end encrypted cloud sync. your data is always encrypted, even to us.
your data stays on your device.
most AI assistants send everything you say to distant servers. erys is different. your conversations, your memories, your personal brain - it all lives on your phone. we can't see it. we can't sell it. it's yours.
data sent to servers
on-device processing
if you choose cloud sync

just talk
chat naturally about anything. erys learns what matters to you over time.
it remembers
