[THE CHATBOT BUILT FOR AI AGENTS]
That's Forrester's finding — not ours — and muro is how you deliver it. Not a canned bot: it answers every visitor from your own docsand product context, in their language, and hands off to you the moment it isn't sure.
42h
The average business takes 42 hours to answer a new lead. muro replies in seconds.
Source — Harvard Business Review
Every second a visitor waits, they're closer to leaving. muro answers questions in seconds, 24/7 — so you catch them while they're still on the page, not after they've gone.
[THE INBOX]
Run your shop, your SaaS and your docs from a single workspace. Switch project in one click — each keeps its own widget, team and tone. Unlimited agents on all of them.
