Share room key with users on your same IP.
How it works
CopyPaster creates a temporary room from the public IP address visible to the service. Devices routed through that same address can see the room content without creating an account. This is useful for quick transfers, but it is not end-to-end encrypted or intended for confidential data.
Step 1
Connect both devices through the same public internet connection, then open CopyPaster in each browser.
Step 2
Use Text for notes and links, Files for temporary uploads, or Chat for short room conversations.
Step 3
Matching room keys mean both browsers were assigned to the same public-IP room.
The text panel accepts up to 20,000 characters and synchronizes changes between room participants. Chat is designed for short messages. File sharing accepts PNG, JPG, WEBP, PDF, TXT, and DOCX files up to 10 MB. Uploaded files expire after one hour.
A public-IP room is shared by anyone whose traffic reaches CopyPaster through the same public address. That can include family members, coworkers, school users, customers on guest Wi-Fi, or devices behind a VPN gateway. Do not paste passwords, payment details, private keys, medical records, or other sensitive information.
Clear shared text and chat when the handoff is complete. Remove files sooner if they are no longer needed instead of waiting for automatic expiry. If two devices show different room keys, they are using different public routes and will not share the same room.
Read practical instructions before sharing important material, especially on workplace, school, guest Wi-Fi, carrier, or VPN connections.
