Getting started
Sign up. Go to buildagent.atensorlab.com and click Get started free. Sign in with Google, or create an account with your email address and verify it from the email you receive.
Create an agent. Click New agent. Give it a name (e.g. "Acme Help") and a short description. For the instructions, pick a template (Customer support, Tutor, Docs Q&A or Sales assistant) or click Write with AI, then fill in anything in [brackets]. Save.
Add knowledge. Open the Knowledge tab.
- Website: paste your site's address, keep Follow links on the same site on, choose how many pages (up to 200) and how often to keep it up to date (daily or weekly), then click Add website.
- Files: drop PDFs, Word documents or text files.
- Text: paste FAQs or policies with a title.
Wait until each source shows Ready.
Test it. Open the Chat tab and ask the questions your customers ask. If an answer is missing or wrong, add that information as knowledge (a Text source is quickest), then ask again.
Turn on sharing. Open the Share tab and switch on Public access.
Design the chat. Open the Widget tab and follow the checklist: a welcome message that says what the agent can help with, your brand color, at least 3 starter questions, follow-up for unanswered questions, and your privacy policy link. Click Save; the preview updates.
Add it to your website. In the Share tab, copy the Chat bubble code and paste it into your site (see Installing on your website). Or share the link or QR code.
Check Insights every week. Add knowledge for the questions under Knowledge gaps and follow up on leads.
Tips for good answers
- Add the pages and documents customers actually need: FAQs, pricing, shipping, returns, policies, contact.
- Keep instructions short and specific: who the agent serves, the tone, and what to do when it doesn't know.
- Set website sources to update daily or weekly so answers follow changes to your site.
