Live chat, built in

A lightweight widget sits on your website. Customers click, type, and your team sees it instantly. No accounts, no downloads, no friction.

Protected by default

Every message — inbound and outbound — passes through norse3, a best in class AI moderation layer. Sensitive data is caught before it leaves. Your customers are protected without knowing it.

Nothing you don't need

No ticket hierarchies. No workflow builders. No enterprise complexity tax. Lettr does one thing — it lets you talk to your customers — and it does it well.

Support tools got complicated. We went the other way.

Most support platforms start simple and then bolt on features until you're paying for a CRM, a knowledge base, an analytics suite, and a chatbot builder you never asked for. Your team spends more time configuring the tool than using it.

Lettr strips all of that back. Your customer sends a message. Your agent replies. The conversation is secure, fast, and human or AI. That's it.

Behind the scenes, every message is scanned by our AI moderation engine to catch sensitive data, harmful content, and policy violations — in both directions. Your customers are protected. Your agents are protected. And you didn't have to configure a single rule.
