NextPotion turns any ordinary file into an encrypted container that carries its own access rules. Drop a file into the desktop app, decide who may open it and when, and share it anywhere — the protection rides inside the file, so your data stays sealed through email, chat, and cloud even when the channel isn't.
What makes it different
Most security guards the place a file sits or the road it travels — a server, a device, a network, an app. NextPotion guards the file. You drop any ordinary file into the desktop application, set the rules for who may open it, and generate an encrypted container with those controls sealed inside. Because the protection is part of the file, it can't be stripped off, left behind, or outrun when the file moves.
Encryption happens entirely on your device with 256-bit AES. NextPotion never sees your files and never stores them — they remain solely in your possession. There is no central library of plaintext to raid and therefore no single point of attack. Reaching a protected file would mean independently breaching both your system and ours at the same time, a fundamentally harder problem than defeating either one alone.
The key is generated and kept on your machine; the plaintext never leaves it. Our role ends at the software. That isn't a promise to look away — it's an architecture in which there is nothing on our side to look at, even if we wanted to or were compelled to.
Email it, drop it in a chat, push it to cloud storage — the container carries its rules wherever it lands. The transport no longer has to be trusted, because the file doesn't depend on it. Only the recipients you named can open it; everyone else, and every system in between, sees nothing but ciphertext.
Today both people and autonomous software agents move, copy, and read files at machine speed, and perimeter defenses were never built for that. NextPotion lets you decide which files AI systems may index — and even which parts of a file they may touch — so sensitive content is never scanned, stored, or surfaced by tools you didn't authorize. File-native encryption becomes a hard constraint on autonomous data movement, not a policy you hope is honored.
Four steps, one file
The NextPotion desktop app. Drag, set the rules, generate, and share — every step runs on your machine, and the encryption key never leaves it.
Talk to usPull any ordinary file — document, spreadsheet, image, or archive — into the application.
Name who can open it, for how long, what each viewer sees, and whether AI may index it.
The app builds an encrypted, trackable, revocable container — entirely on your device.
Send it through any channel you like. Only the recipients you designated can ever open it.
Once a file is protected, its rules belong to you — not to the inbox it lands in or the drive it's copied to. Every control below is embedded in the container itself and stays enforceable after the file has left your hands.
Access is granted to the named recipients you choose, not to whoever happens to hold a copy. Decide exactly who may open a file and from what moment — and change that decision later without re-sending anything.
The same document can display differently depending on who is looking. A single file replaces the stack of separate versions you'd otherwise cut, label, track, and reconcile by hand — and there's no risk of the wrong copy reaching the wrong reader.
Set an expiration date, a future start date, or both. A file can stay completely unopenable until a release time and lock itself again afterward — purpose-built for embargoed announcements and scheduled material that must not surface early.
See who opened a file and when. Revoke access at any time — even after the file has been sent — and grant additional access just as easily when the circle of trust needs to grow. Control doesn't end at the send button.
Control which files AI systems may index — down to which parts of a file are off-limits — keeping sensitive content from being scanned, stored, or surfaced by automated tools. A constraint enforced by encryption, not by a setting you hope is respected.
