One script tag
The whole install is one snippet before the closing body tag. No build step, no plugin to keep updated.
SquarespaceLive chat for Squarespace, added through Code Injection
Squarespace does not include live chat, and its Code Injection panel is made for exactly this. Paste one script tag into the footer injection and every page on your site gets an on-brand chat widget with a real inbox behind it.

InstallThe snippet, and where it goes on Squarespace
Paste this into Settings, Advanced, Code Injection, in the Footer box. Replace the placeholder with the widget key from Settings, then Install; the snippet there already carries it.
Squarespace, then Settings, then Advanced, then Code Injection.
Paste the snippet into Footer.
Save. Code Injection needs the Business plan or above.

</script>What the widget gives a Squarespace site
Matches your site
Brand colours, launcher, avatar, header text, light or dark. The chat reads as part of the page.
Pre-chat form and help center
Ask for a name or email first if you want, and let visitors read your help articles inside the widget.
An AI agent that answers first
Trained on your pages and documents, it takes the first reply on website chat and hands over when unsure.
Show it where it helps
Only on some pages, hidden on others, by country or IP, and hidden when nobody is online.
Every reply in one inbox
Website chats land beside WhatsApp, Instagram, Telegram and email, with assignment, notes, tickets and analytics.

FAQ
Squarespace questions
Yes, through Code Injection, which is available on the Business plan and above. Personal plans do not include it.
- Where it lives: Settings, then Advanced, then Code Injection, in the Footer box.
- Paste once, every page. Footer injection runs site-wide, so the launcher appears on every page after you save.
- On a Personal plan? Code Injection is not included, so the widget cannot be added until you move to Business.
The install docs show the panel step by step.
