dropit

English · 简体中文

Send it on one device. It's waiting on all the others.

A link from your phone, a paragraph from your browser, a file from your terminal: one move drops it in, and a few seconds later it's in Obsidian, in a folder on your computer, or in any browser. No chat to scroll, no "send to" to pick — just your own devices.

Items are kept for 1 day after they're sent (10 days on a paid plan): dropit delivers, it doesn't store.

This repository holds the open-source clients. The Obsidian plugin has its own: smart-kits/dropit-obsidian.

Open dropit.smart-kits.xyz on any device: it recommends the client that fits that device, and every client's install steps are under Devices.

A day with it

• On the train, an article on your phone: Share → dropit. At your desk it's already a note in Obsidian, title and summary included.
• At your desk, a paragraph in the browser: select, Alt+Shift+S. On your phone, the paragraph with a link back to the page.
• A screenshot you'll need on your phone: Alt+Shift+D, ⌘V, Enter.
• A borrowed computer: open the web inbox, join with a code, drag the files in, sign out — the device is gone from your account.
• A long build: make && dropit send "build done ✅", and your phone tells you.

The web inbox

_{Shown: a NASA photograph and page (public domain) · a Lonely Planet page link.}

dropit.smart-kits.xyz, in any browser, phone or computer. Nothing to install.

Sending

• Type or paste into the envelope, press Enter (or the red stamp). Shift+Enter for a new line.
• Drop files anywhere on the page, paste a screenshot, or Attach files — up to 10 at a time, sent with the text as one delivery.
• A failed send is stamped RETURNED with the reason and stays on the envelope; nothing you wrote is lost.

Receiving

• Every delivery is a letter with a postmark: the date, the time and where it came from. Links show their title and summary; selections and images show From page ↗. Copy and Download are on each letter, with how long it's kept.
• The page doesn't listen live: press Pull new items to fetch what's new. Pull again… fetches everything, the last N items or the last N days.

Devices

• Show pairing code gives a 6-character code and a QR code (also copied for you). Scan it with a phone camera, or type it on the other device; the page notices when it has joined.
• Every device on your account, when it was last seen, and Revoke to remove one at once.
• Your plan and space used, and the free and paid plans side by side.
• Create bookmarklet gives a bookmark that sends the current page, or the selected text, from any browser without installing anything. Each bookmarklet is a device of its own, with a send-only key.

Good to know: joining in a browser makes it one of your devices — on a borrowed computer, Sign out on this browser removes it from your account right away. The interface is English or Chinese (switch at the top right) and follows your light or dark setting.

Start in three steps

1. Your first device creates the account. In the web inbox: Just for now? Use it in this browser → Create a new account. Or in the terminal: dropit pair; in Obsidian: Settings → dropit → Create a new account; in the browser extension: Create a new account under the join form.
2. Show a pairing code on that device: web inbox → Devices → Show pairing code; terminal: dropit code; Obsidian: Settings → dropit → Add a device; browser extension: it shows one right after creating the account, later + Add a device at the top of the popup.
3. Join from every other device with the code — or scan its QR code with the phone's camera. On an iPhone, scanning it opens the shortcut's setup with the code filled in — tap Set up the shortcut.

Codes last 5 minutes, work once, and are forgiving: case, spaces, dashes and 0/O or 1/I/l mix-ups don't matter.

Where the install files come from. Every version of every client is a GitHub Release (extension-…, cli-…, shortcut-…; the Obsidian plugin's are in its own repository), with each file's SHA-256 in the notes. The downloads on dropit.smart-kits.xyz are byte-for-byte copies, for places where GitHub is hard to reach, and the install script checks the hash before installing.

Using an AI coding agent (Claude Code, Codex, Cursor…)? Paste this:

Install dropit on this machine for me by following
https://raw.githubusercontent.com/smart-kits/dropit-client/main/AGENTS.md
Ask me before creating an account, and never show or commit my token.

It installs and joins the terminal client, checks that it works, and tells you exactly what to click for the parts that need your hands (loading the browser extension, adding the iPhone shortcut). Agent instructions: AGENTS.md.

What you can count on

• Nothing to choose. Sending never asks a question; everything goes to all your devices.
• You know whether it went. Every client shows a clear sent or a clear reason why not — offline is never shown as sent.
• Nothing lost, nothing twice. A receiver moves on only after an item is safely written: a crash means a repeat at worst, never a gap. The same thing sent twice in a row within a minute (a double tap, a retry) is kept once.
• Every device on its own. Each is joined separately and can be removed separately. Send-only devices — the iPhone shortcut, a browser extension joined with a code, bookmarklets — can't read anything you've sent.
• Small and open. The terminal client is one Node.js file; the extension loads as it is; no build step, no dependencies.

Security & privacy

• Each device's key stays on that device — terminal: ~/.config/dropit/config.json (readable only by you); extension: the browser's local extension storage; Obsidian: the plugin's data.json; web inbox: the browser's local storage.
• Keys come in two kinds: full (send, receive, add devices) and send-only. The extension and the iPhone shortcut join send-only, so a leaked key can't read your items. A browser extension that created the account holds a full key, so it can add your other devices.
• Lost a device? Remove it from any other one: web inbox → Devices → Revoke, or dropit devices and dropit revoke <id>.
• Signing out of the extension removes it from your account. Joining or pairing again on the same computer — after reinstalling, say — takes the earlier one's place instead of using another device slot. To recognize it, the client sends the key it had, if any, and a fingerprint: a SHA-256 hash of facts that stay put (extension: browser brand, platform, CPU cores, memory, time zone, graphics chip; terminal: host name, user, OS, CPU, memory, the machine's ID and the config path). Only the hash leaves the device, and it is not a credential.
• What the service keeps, for how long and who can see it: Privacy.

Problems and ideas

Open an issue. Every client links there: the extension at the bottom of its popup, the web inbox at the bottom of the page, the terminal in dropit's help text, Obsidian under Settings → dropit → Feedback. Issues are public — never paste a key (dk_…). For questions about your account you'd rather not post publicly, email support@dropit.smart-kits.xyz.

Contributing

• Turn on the secret scan before your first commit, so a key can never land in the repository:

  brew install gitleaks          # or see https://github.com/gitleaks/gitleaks
  git config core.hooksPath .githooks

• Run the tests before you push (no dependencies): node test/i18n.test.mjs, node test/extension.test.mjs, node test/cli-render.test.mjs, node test/cli-logic.test.mjs.

• Every interface string lives in an English and a Chinese table; add both, or the test fails.

• Commit messages are in English. Docs come in pairs: README.md (English) and README.zh-CN.md (简体中文) — update both.

Interfaces follow your language: English, or Simplified Chinese when the system, browser or Obsidian is set to Chinese. The terminal reads LANG; DROPIT_LANG=zh or DROPIT_LANG=en overrides.
