AI Chat testing Beta
Paste your assistant ID or embed URL from Dashboard → Chat. Load the widget on this page. No separate test file needed.
Setup
- Copy your assistant ID or full
<script src=…/c/{id}/widget.js>URL. - Paste below and click Load chat widget.
- Use the 💬 button bottom-right, or run a quick API test on the right.
On this site, you can paste just the ID (e.g. 19c1ee8e). We use the current hostname. Share a quick link: /playground?chat=your_id
Your embed code
<script src="https://formsig.com/c/{assistant_id}/widget.js" async defer></script>
Tip: leave Allowed domains empty in Chat settings, or add this site's hostname, so the widget works here.
