1. The current workspace pairs two browsers
CopyPaster’s main workspace now connects an invited browser through a QR code or pairing link. It does not automatically put everyone on the same public IP into that direct session. Check the receiving device before sending content and keep your invitation private.
Text, files, and chat use the paired browser connection. Files are held in browser memory rather than the direct workspace’s server storage. Refreshing or closing the page clears the in-page files, so save them locally when needed.
2. What the invitation proves
An invitation allows its holder to attempt to join; a device name is just a label. Neither proves a person’s identity. Share the invitation through a channel you trust, verify the other screen, and disconnect if an unexpected device joins.
Encrypted transport protects data on its journey. It cannot prevent the recipient from taking a screenshot, copying text, or keeping a downloaded file. Send only what you intend the other device to receive.
3. Why older public-IP rooms were different
Earlier CopyPaster guides described rooms grouped by public internet address. A home, office, school, carrier, or VPN gateway can put many people behind the same public address. In that model, a matching room key described shared network membership, not a private invitation.
If you encounter a legacy network-room tool or an old screenshot, do not treat its room key as a password. The QR-pairing instructions in the current guides describe the main workspace instead.
4. Clipboard sharing deserves its own decision
Automatic sharing can send newly copied text to the paired device while the tab is focused. Enable it only when you want that behavior, and stop it before copying sensitive content. Clipboard permission is separate from the pairing itself.
For a read-once secret link, use Private Notes and review that feature’s expiry behavior. For direct transfers, verify the receiver, save what you need, and disconnect when the handoff is complete.
