BT DM Check Bookmarklet

A one-click way to send any LinkedIn DM draft (or any text you select on the page) to the BT Tree Care Copilot's DM Check, without leaving LinkedIn.

Drag this button to your bookmarks bar

Make sure your bookmarks bar is visible (Chrome → View → Always Show Bookmarks Bar). Then drag the orange button below up onto the bar.

📩 BT DM Check

What it does: grabs your currently-selected text on the page (or the contents of the focused textarea if nothing is selected), opens the BT Tree Care Copilot in a new tab, and pre-fills the DM Check with your draft. You'll need to log in (password: treecare-2026-bt) on first use; subsequent uses are instant.

How to use it

  1. Open a LinkedIn DM thread and start composing a message in the composer (don't send yet)
  2. Either select all the text in your draft (Cmd/Ctrl + A inside the composer), OR just click in the composer and leave the cursor there
  3. Click the 📩 BT DM Check bookmark
  4. BT Tree Care Copilot opens with your draft pre-filled in DM Check — review the strict feedback, copy the rewrite if needed
  5. Paste back into LinkedIn, send

javascript:(function(){
  var s = window.getSelection().toString().trim();
  if (!s) {
    var ta = document.querySelector('textarea,[contenteditable=true]');
    s = ta ? (ta.value || ta.innerText || '').trim() : '';
  }
  if (!s) {
    alert('Select your DM draft text first.');
    return;
  }
  var url = 'https://bt-tree-care-copilot.jason-8ce.workers.dev/?dmcheck=' +
    encodeURIComponent(s.slice(0, 2000));
  window.open(url, '_blank');
})();

Note: the BT Tree Care Copilot needs a small change to detect the ?dmcheck=… query param and auto-open the DM Check modal with the text. That's deployed as of v3.1.
