Empti streams each file to the app that asks for it, encrypted the whole way, so there's nothing to copy over and nothing to wait for.
Empti fetches only the parts an app reads, so a 52 GB master starts as fast as a small clip.
Sign in on another Mac and your files are already there. Changes reach the others in about 30 seconds.
Finder, QuickTime, DaVinci Resolve and Terminal treat it like any disk. No plug-ins, no import step.
Point Claude Code, Codex or your own scripts at /Volumes/Empti, or use the empti command when the drive isn't mounted.
Restore an earlier save or a deleted file from any of your Macs, or fork a whole drive without copying a byte.
Files are encrypted on your Mac with a random key that only your passphrase unlocks. We can't read them.
Search from any app, keep collections, switch drives and move big files off your Mac, all from one panel.
One drive for your footage, your projects and everything you'd rather not carry around.
Your editor reads only the frames it plays, so a 52 GB master scrubs like a small clip. Nothing is copied to your Mac first.
Your photo editor opens each RAW from Empti as you reach it. The rest of the library stays in the cloud.
Your DAW streams each stem as it plays, and the session opens where you left it on any of your Macs.
Scenes, 8K textures and scans live on Empti. Your 3D app reads them like any local folder.
Right-click, Copy share link. They open it in a browser, decrypted on their screen; set it to expire or add a password.
Claude Code, Codex, shell scripts and the empti command read and write it like any folder, and every Mac sees the result.
Comments, @mentions and activity sit beside each file, and what people write is encrypted like the files.
Every file is encrypted on your Mac before it leaves, with a random key that only your passphrase unlocks. We can't open your files, so we can't hand them to anyone.
Your other cloud drive keeps files somewhere else. Empti is the one built so they never have to come down.

Empti keeps the file in encrypted storage and shows it in Finder. When an app opens it, Empti fetches only the parts the app reads and keeps recent ones up to the limit you set.
Files you marked Keep on this Mac open as usual, and so do recently opened ones. Everything else opens again when you reconnect.
You do. Your files are locked with a random key, and your passphrase locks that key. We keep only the locked copy, so your other Macs can unlock it and we can’t.
Use the recovery key you saved at setup. Without either one, nobody can decrypt your files, including us.
Yes. Copy a share link and send it. They open it in any browser, and the file is decrypted there. We store the link's settings, never its key.
Use the empti command. It signs in with your account, unlocks with your passphrase and reads or writes the drive without mounting it.
