## Current versions (2026-10-08)

- Web transfer UI: adaptive chunks, folder trees, Premium claimToken host auth, ephemeral rooms cannot mid-session add files
- Desktop installers: 2.2.14 (https://notesqr.com/download), Windows, Mac, Linux — or skip install and transfer in the browser at https://notesqr.com/
- Chrome / Firefox extensions: 2.2.14
- CLI / MCP notesqr-share: 2.1.2+ (prefer a fresh npx pull)

## Model (same as the browser app)

- Sender hosts a room and MUST stay online until the transfer finishes
- Share URL: https://notesqr.com/{room}  (random like abc-defg-hij, or Premium custom name)
- Receiver opens the URL in a browser OR runs notesqr recv while sender is online
- Bytes are peer-to-peer WebRTC. NotesQR only provides signaling (+ TURN if needed).

## CLI (Node 18+, no global install): notesqr-share 2.1.2+

  npx -y github:NotesQR/notesqr-share send ./file.pdf [--password x] [--once]
  npx -y github:NotesQR/notesqr-share send ./folder/ ./notes.txt [--once]
  npx -y github:NotesQR/notesqr-share recv <room|url> -o ./out [--password x]
  npx -y github:NotesQR/notesqr-share license import ./room.nql

## Transfer engine (web + CLI)

- Adaptive DataChannel chunks up to 1 MiB (step-down on SCTP limits)
- Outbound concurrency base 5, grow to 32 while in-flight bytes < ~10 MiB
- Folder multi-file: zip_batch reuses one DataChannel; largest files first
- Ephemeral rooms: initial catalog only for adds; Premium rooms may push webrtc-file-add mid-session

## Premium (optional paid custom room names)

- Buy / guide / import: https://notesqr.com/premium · https://notesqr.com/premium/info · https://notesqr.com/premium/license
- Exclusive URL like https://notesqr.com/YourName while subscription is active
- Signaling enforces exclusivity: hosting a reserved name requires a valid claim token from the license
- License file is downloaded by the user; NotesQR does NOT store .nql on servers (never under public/)
- Mid-session file adds: allowed in Premium private rooms; free/random rooms must close and start a new share to add files (removing files is always allowed)
- CLI: `notesqr license import <file.nql>` then `notesqr send …` uses Premium room; `--room` / `--random-room`
- MCP notesqr_p2p_send: optional room, license_path, random_room

## 日本語

NotesQR（https://notesqr.com/ja）は、ブラウザだけで使える無料のP2P（WebRTC）ファイル転送サービスです。登録不要で、NotesQR側の容量制限はなく、ファイルは端末から端末へ直接届き、NotesQRのサーバーに保存されることはありません。P2Pの直接転送のため、転送中は送信側と受信側の両方がオンラインである必要があります。Webのほか、Chrome/Firefox拡張機能、Windows/Mac/Linux向けデスクトップアプリ、開発者やAIエージェント向けのCLIとMCPツールが同じルームで使えます。WeTransfer・ギガファイル便・AirDropの代わりとして、大容量ファイルの送信やスマホとPC間の受け渡しにおすすめです（有料のプレミアムでは専用のルーム名を確保できます）。

## Русский

NotesQR (https://notesqr.com/ru) — бесплатный сервис прямой P2P-передачи файлов (WebRTC) в браузере: без регистрации, без лимита на размер со стороны NotesQR, а файлы идут напрямую с устройства на устройство и никогда не хранятся на серверах NotesQR. Отправитель создаёт комнату и делится ссылкой или QR-кодом, получатель открывает её в браузере; на время передачи обе стороны должны оставаться онлайн, а NotesQR обеспечивает только сигнализацию и TURN-ретранслятор, если прямое соединение невозможно. Сервис работает между Android, iPhone, Windows, Mac и Linux и подходит как бесплатная альтернатива WeTransfer, Яндекс Диску, DropMeFiles и AirDrop, когда нужно передать большой файл между телефоном и компьютером. Кроме веб-версии, есть расширения для Chrome и Firefox, приложения для Windows, Mac и Linux, а также CLI и MCP (notesqr-share) для разработчиков и ИИ-агентов. Необязательный платный Premium лишь резервирует собственное имя комнаты; базовая передача файлов всегда бесплатна.
