Question 1

Is UserFB free?

Accepted Answer

There's a free tier to get started; paid plans unlock higher AI reply quotas and advanced features.

Question 2

Does setup require engineering?

Accepted Answer

Just one script tag, with optional logged-in identity support — plus a Next.js backend integration example.

Question 3

What if the AI can't answer?

Accepted Answer

It hands off to a human automatically or on request, and notifies you via Feishu / DingTalk / WeCom / email so an agent can step in.

Question 4

How do I train the knowledge base?

Accepted Answer

Upload documents or paste content and click "Save & rebuild index" — answers are powered by vector retrieval.

Question 5

Is my data safe?

Accepted Answer

Your data is always yours. Some comparable products deleted free-tier data; UserFB never does that.

Question 6

Multi-language and multi-product?

Accepted Answer

Native multi-tenant architecture lets you manage multiple products independently, with English and Chinese UI.
