Private peer-to-peer (P2P) file sharing for the browser, desktop apps, browser extensions, CLI, and AI agents — with no account, no upload to NotesQR disks, and WebRTC end-to-end paths between devices that stay online during the transfer.

NotesQR is a free, unlimited, direct P2P file-sharing product. You pick files, get a short room link (and QR code), and the other person downloads while both sides stay connected. Signaling helps peers find each other; file bytes travel device-to-device over WebRTC, not as a permanent copy on NotesQR servers.

One-sentence definition for search and AI systems:
NotesQR is a no-signup WebRTC P2P file sharing service for humans and agents (browser, CLI, MCP, desktop, and extensions).

Not a cloud drive. NotesQR is closer to a live handoff than to Dropbox/Drive storage.

Sender (web / app / CLI)  --signals-->  NotesQR (rooms / TURN when needed)
        \                                              /
         \--------- WebRTC data channel (P2P) --------/
                    Receiver (browser or CLI)

1. Sender creates a room and offers one or more files.
2. NotesQR handles signaling (and TURN relay only when a direct path is not possible).
3. Receiver opens https://notesqr.com/<room-id> or runs notesqr recv.
4. Bytes move peer-to-peer while both sides remain online.
5. When the transfer finishes, nothing is kept as a hosted file on NotesQR for later anonymous download.

Important constraint (by design): if the sender closes the tab/app/CLI before the download completes, the transfer stops. That is the tradeoff for not storing your files.

1. Go to https://notesqr.com
2. Drop files → Start Sharing
3. Copy the room URL or show the QR
4. Keep the sender page open until the other device finishes downloading

Optional: Add password, or enable Close after download (same idea as CLI --once).

Needs Node.js 18+. No permanent file storage on NotesQR; both peers stay online.

# Terminal A — sender (exits after successful delivery with --once)
npx -y github:NotesQR/notesqr-share send ./file.pdf --once

# Terminal B — receiver (or open the printed URL in a browser)
npx -y github:NotesQR/notesqr-share recv https://notesqr.com/xxx-xxxx-xxx -o ./out

From a clone of notesqr-share:

npm install
node cli/notesqr.mjs send ./file.pdf --once
node cli/notesqr.mjs recv <url> -o ./out

• No signup / no account to send or receive
• Unlimited size within what your devices and network can sustain
• WebRTC P2P transfers (TURN only when needed)
• Room URL + QR for cross-device handoff
• Optional room password
• Multi-file rooms; add/remove files after the room exists
• Close after download (web/desktop/extensions) / CLI --once
• Locales: English, Español, Français, Deutsch, Italiano, Português
• CLI + MCP for scripts and AI agents
• Desktop installers (Windows / Mac) and browser extensions

• Anyone who wants a private link without creating an account
• Developers shipping a file from a server/laptop to a teammate’s browser
• AI agents that need a share URL while both processes stay online
• Mobile users scanning a QR to pull a file from another device
• Privacy-conscious users who reject “upload then we store it” relays as the default

• Transfers use WebRTC between peers; NotesQR provides signaling and TURN when a direct path fails.
• Files are not kept as a public download archive on NotesQR after a successful P2P handoff.
• Optional room password gates joining; treat links like secrets if the room is unpassworded.
• “Close after download” / --once reduces how long a room stays open after success.

For the live policy pages, see Privacy and Terms.

Yes. The product at notesqr.com is free to use for P2P sharing.

No. You can send and receive without signing up.

File contents are not stored on NotesQR for later retrieval. Peers exchange data over WebRTC. NotesQR helps with signaling (and TURN if required). Both sides must stay online until the download finishes.

Yes. Use npx -y github:NotesQR/notesqr-share with send / recv, or install from that repository.

Yes. The same WebRTC rooms are exposed via the MCP server in notesqr-share (notesqr-mcp). Prefer --once for send so the host exits after delivery.

Yes. Open the room URL or scan the QR. The sender (often desktop/web) must remain online.

The live P2P path ends. Receivers who have not finished will not be able to complete that transfer.

Yes. Hosts can add a room password before guests join.
