Smart Paste
Enable site-specific link replacement in Chrome and control whether pastes prompt or run automatically.
Connect the extension to SimpURL
Install the SimpURL Smart Paste Chrome extension, open SimpURL in a browser tab, and sign in. Keep one signed-in SimpURL tab open while you use the extension. There is no separate extension password or setup: Smart Paste uses that signed-in SimpURL browser session.
- Use Chrome 119 or newer and open a normal SimpURL tab.
- Sign in to SimpURL, then open the Smart Paste extension popup.
- If the popup says Connect your SimpURL session, select Sign in to SimpURL and return to the popup.
Enable one site at a time
Smart Paste remains inactive on sites you have not enabled. The popup asks Chrome for permission when you enable the current site. A saved Smart Paste site still needs that browser permission before the content script can run there.
- Open the site where you publish and select the extension icon.
- Select Enable on this site, then accept Chrome's site-access prompt.
- Confirm the popup shows Smart Paste is ready here and the site is enabled.
- To review saved hosts, open Settings > Link setup > Smart Paste sites.
Choose the paste workflow
Paste one URL or a paragraph containing several URLs into a supported text input, textarea, or contenteditable editor. The extension holds the original text while it checks the site and creates replacements, then inserts the shortened links in place.
- Leave Shorten automatically off to review the prompt, then choose Paste original or Shorten link for one URL, or Shorten N links for a multi-link paste.
- Turn on Shorten automatically to skip the confirmation prompt on enabled sites.
- Use Keep analytics together to reuse an existing matching SimpURL instead of splitting analytics across duplicates.
- Keep the editor open while the extension shows "Shortening this link..." or "Shortening N links..."
Recover safely from a problem
If the extension cannot confirm the request, it preserves the original paste and tells you to check Links before retrying. A duplicate prompt offers Paste original, Create new, or Reuse existing. Password, payment, and one-time-code fields are excluded from Smart Paste.
- If the popup says Access needed, enable the current site and grant Chrome permission.
- If it says Connect your SimpURL session, open SimpURL and sign in again.
- If a request times out, check Links for completed links before trying again.
- Use Settings > Link setup > Smart Paste sites to remove a host you no longer want enabled.
