How it works

From help text to a live chat in three steps

No ML team, no integration sprint. If you can paste text, you can ship a support agent.

01

Paste your help text

Paste in your help articles, policies and FAQs. Lumi indexes them and searches them before it answers.

02

Add one script tag

Copy the snippet into your site and pick the button colour, text colour, side and label. No website? Share a chat link instead.

03

It answers, you step in

It answers your visitors day and night. When someone asks for a person, or the AI decides one should take over, you get an alert and can take the chat.

<script src="widget.lumi-support.com/widget.js" data-agent="…"></script>

See it work

Watch it do the work

The chat is recreated from the product, with a sample business. Everything around it is an illustration.

Answers

Answers from the help text you paste in

Paste in your help articles, policies and FAQs. Lumi searches them before it answers, and can search again with better words.

Acts

Does the job in the tools you connect

Connect your own remote MCP servers and tick the tools it may use. Here it checks your bug tracker, finds no match, and files the bug in one reply.

Up to 6 model calls per reply, so calls can chain
Every tool call is logged in your transcript
Tool results are marked as untrusted data

Calls you in

Hands you the chat when a person is needed

When a visitor asks for a person, or the AI decides one is needed, you get an alert. Join, reply as yourself, then hand back to the AI.

Alerts by email, dashboard bell and browser push
Nobody online? It takes their email
2 teammates included per AI agent

It’s the AI’s call, guided by your instructions. Billing question? Tell it to call you in.

Forms

Contact forms with their own inbox

Put a contact form on any page. Messages land in a Forms inbox beside your chats, and you reply by email, in your brand.

A hosted page, an iframe or your own HTML form
Form messages use no credits
Your sender name, logo and colour on every reply

The bill

Prepaid, with no overage bill

$12 a month per AI agent + tax (£9 + VAT in the UK). When the agent’s credits and the shared top-ups are used up, the chat asks for an email.
