Peek is a zero-install, no-account file transfer tool built for the messiest setups — library PCs, lab machines, kiosks, a friend’s laptop, a locked-down work computer. If it has a browser, it can send and receive. Open a tab, scan a code, transfer, walk away. Nothing is left behind.
Why Peek
You know the moment: you need to get a file onto (or off of) a computer that isn’t yours. No USB stick. No login to your cloud drive. No permission to install anything. Emailing it to yourself feels wrong, and that USB port might be disabled anyway.
Peek is the answer to “I just need to move this one file, right now, safely.”
What it does
📲 Pair in seconds with a QR code One device opens Peek and picks files. The other device scans the QR — that’s the whole handshake. No usernames, no passwords, no setup.
🔒 Encrypted end-to-end Files are encrypted in your browser before they ever leave. The decryption key lives in the link itself (the part after #) and is never sent to any server. Even the people running Peek can’t see your files.
⚡ Direct when possible, relayed when not When both devices can talk directly, your files take the fast lane — peer to peer. When a network blocks that, Peek falls back to a relay that only ever carries scrambled data. Either way it just works.
↔️ Two-way in one session It’s not one-and-done. Once two devices are paired, files flow both directions — send some over, get some back, all in the same room.
⏳ Temporary by design Sessions expire automatically (60 minutes) and either side can end them instantly. Nothing lingers on the shared computer afterward — no history, no leftover files, no trace.
👀 Peek links — share a file with anyone Generate a short-lived link to a single file. Send it over chat, email, anywhere. PDFs and images preview right in the browser; everything else (zips, notebooks, archives, any file type up to 50MB) downloads securely. Optional “burn after viewing” deletes it the moment it’s opened.
📋 Clipboard sync Need to move a chunk of text, a password, a snippet? Sync the clipboard between the two devices without touching a file at all.

The 3-step flow
Pick your files on the sending device.
Scan the QR on the receiving device.
Transfer, then close. Send, receive, end the session. Done.
Peek is for the in-between moments — the borrowed computer, the public terminal, the quick handoff — where every other option is too slow, too permanent, or too risky.
