Documentation

Command-D remembers things for you. One keystroke on your Mac, one share on your phone — saved, enriched, and searchable. No account needed, ever.

Installing on Mac

Download the app (Apple Silicon), unzip, and drag Command-D.appto Applications. This is an early build that isn’t notarized by Apple yet, so the first launch takes one extra step:

  1. Double-click the app — macOS will refuse; dismiss the dialog.
  2. Open System Settings → Privacy & Security, scroll down, and click Open Anyway next to Command-D.
  3. The ⌘D icon appears in your menu bar. Use its menu to enable Start at login.

Terminal alternative for step 1–2: xattr -d com.apple.quarantine /Applications/Command-D.app

Saving things

Mac — copy anything (⌘C), then hit ⌘D. A “Stored ✓” toast appears under the menu bar icon. Links, text, and images on the clipboard all work. The menu bar ⌘D icon shows your five most recent saves.

Android — install the app (the Install the app button on the homepage, or Chrome menu → Add to Home screen → Install). Then use the regular share sheet from any app — YouTube, LinkedIn, your browser — and pick Command-D.

Windows — install the app the same way in Chrome or Edge (install icon in the address bar). Command-D then appears in the Windows Share menu, and the app window is your list. A native tray app with a global hotkey is planned; until then, paste into the list or use Share.

Browser — paste a link or note in the box at the top of your list.

Every saved link is enriched automatically in the background: title, description, preview image, favicon. YouTube, X and TikTok links get the real thing — the video title and thumbnail, the tweet’s text and photos, and the video behind it (a tweet that embeds a YouTube video is saved as something to watch). Saving the same link twice never creates a duplicate; it bumps the item back to the top of your list and, if you had marked it done, back into your inbox.

What can be stored:links, text notes (up to 100 KB), and images (any common format, up to 4 MB). Videos are saved as links — Command-D remembers wherethings are and what they’re about; it’s not a file locker.

Finding them back

Your list at cmd-d.com/app is newest-first with full-text search over titles, descriptions, content, and URLs — the enrichment means you can search for words you never typed. Filter by Links, Images, or Text — or ▶ Videos for everything you saved to watch later, whatever site it came from.

Done with something? Hover a card and hit ✓. It leaves your inbox but nothing is deleted: the ✓ Done view shows everything you finished, search still finds it, and ↩ puts it back. Saving is still one keystroke — sorting is optional and comes later, if ever. Items you open from the list are marked opened so you can see what you already looked at. The Mac menu bar does the same: hold ⌥ on a recent item to mark it done without opening it.

Tags are optional too: # on a card adds one, clicking a tag filters the list by it. Your AI can tag things for you over MCP.

One list on every device

Each device starts its own private list — no signup. To make them one list: on a device that has your list, open Pair a device (top right of the list page) → Show code. Enter that 6-character code on the other device within 10 minutes. From then on Mac, phone, and browser share the same list. The Mac app’s Open my list pairs your browser automatically.

Connect your AI (MCP)

Command-D speaks MCP, so Claude, ChatGPT, and Gemini can search your list, and save to it, mid-conversation — “what was that video I saved last week?” just works.

Get your personal connector URL from your list → Pair a device → Connect your AI. It looks like:

https://cmd-d.com/api/mcp?token=cmdd_…

Treat that URL as a secret — anyone who has it can read and add to your list.

Tools your AI gets: search_items, get_recent_items, get_item (read-only; filter by inbox / done, by tag, or media=video for your watch list), save_item — so an agent doing research can ⌘D things for you — and update_itemto archive, restore or tag things (“mark everything about React I opened last week as done”). Nothing your AI does can delete an item.

API

Everything is API-first — your own scripts and frontends are welcome. Create an identity once, keep the token:

# one-time: get a token
curl -X POST https://cmd-d.com/api/devices

# save
curl -X POST https://cmd-d.com/api/items \
  -H "Authorization: Bearer $TOKEN" \
  -H "content-type: application/json" \
  -d '{"content": "https://youtu.be/dQw4w9WgXcQ"}'

# search (add &status=all to include what you marked done)
curl "https://cmd-d.com/api/items?q=rick" \
  -H "Authorization: Bearer $TOKEN"

# watch list: everything with a video behind it, not yet done
curl "https://cmd-d.com/api/items?media=video" \
  -H "Authorization: Bearer $TOKEN"

# done with it (reversible: "archived": false)
curl -X PATCH https://cmd-d.com/api/items/$ID \
  -H "Authorization: Bearer $TOKEN" \
  -H "content-type: application/json" \
  -d '{"archived": true, "add_tags": ["ai"]}'

Your data

What we store: the things you save, the metadata enrichment finds (page titles, descriptions, preview images), and timestamps. No account, no email, no tracking. Deleting an item removes it immediately. Your list is private to your devices and the AI connectors you explicitly add.
