An AI assistant for your website, in one line.

No credit card to browse. 7-day free trial when you start.
How it works
Point it at your site
Give Luca On your site URL (and upload docs if you like). It crawls your pages and learns your business — your services, your hours, your policies.
Paste one line
Copy the embed snippet into your site before the closing body tag. A sandboxed chat launcher appears — no plugins, no framework, no code changes.
It answers & captures leads
Visitors get instant, accurate answers from your own content. When someone wants to be contacted, Luca On captures the lead and notifies you.
Simple, flat pricing
Every plan includes a monthly message quota — a hard cap, no surprise overage bills.
- Basic 1 site · 500 messages/mo · 25 pages $19/mo$190/yr Start free trial
- Pro 1 site + docs · 2,000 messages/mo · 150 pages · leads $49/mo$490/yr Start free trial
- Multi-Site Up to 3 domains · 3,500 messages/mo · 500 pages · leads $99/mo$990/yr Start free trial
Message quotas are a hard cap — when you hit it, the widget pauses until your next period. No overage charges in v1.

Straight answers
Does it make things up?
It answers only from your own crawled content — your pages and the documents you upload. It's instructed to say it doesn't know rather than invent, and it can't reach any other website or another customer's data.
Where do my visitors' chats go?
The widget runs in a sandboxed cross-origin iframe and talks only to the Luca platform. Your content and leads are isolated to your account — no other tenant can ever see them.
What's a "message"?
One visitor turn answered by your assistant. Each plan includes a monthly allowance; it's a hard cap with no overage billing in v1, so your cost is predictable.
How do I install it?
After checkout you get a one-line script tag and a configurator at your dashboard. Paste the line, set which origins may embed it, and you're live.
How do I cancel?
From your dashboard, in two clicks. No contracts, no retention call.
Give your site a memory.
