52.32 GB in Finder0 bytes on this Mac

Stop moving files around.

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.

Opens in a second

Empti fetches only the parts an app reads, so a 52 GB master starts as fast as a small clip.

The same drive on every Mac

Sign in on another Mac and your files are already there. Changes reach the others in about 30 seconds.

Your apps need nothing new

Finder, QuickTime, DaVinci Resolve and Terminal treat it like any disk. No plug-ins, no import step.

Ready for any AI agent

Point Claude Code, Codex or your own scripts at /Volumes/Empti, or use the empti command when the drive isn't mounted.

Every version, for 30 days

Restore an earlier save or a deleted file from any of your Macs, or fork a whole drive without copying a byte.

Only you hold the key

Files are encrypted on your Mac with a random key that only your passphrase unlocks. We can't read them.

Made for big files, and the people who make them.

One drive for your footage, your projects and everything you'd rather not carry around.

Talk about the file, on the file.

Comments, @mentions and activity sit beside each file, and what people write is encrypted like the files.

Only you hold the key.

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.

Questions.

Something missing? Write to us and someone who builds Empti will reply.

How can terabytes take no room on my Mac?

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.

What happens when I'm offline?

Files you marked Keep on this Mac open as usual, and so do recently opened ones. Everything else opens again when you reconnect.

Who holds the key?

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.

What if I forget my passphrase?

Use the recovery key you saved at setup. Without either one, nobody can decrypt your files, including us.

Can I send a file to someone without Empti?

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.

Can I use my drive from a script or a server?

Use the empti command. It signs in with your account, unlocks with your passphrase and reads or writes the drive without mounting it.

Where are my files stored?

On Cloudflare R2, as sealed 4 MiB chunks.

Which Macs does it run on?

Macs with Apple silicon running macOS 26 or later.

The weightless drivefor your whole library.

Empti launches soon. Leave your email and you’ll get one message when it’s ready to download.
