MEET LUMEN

The live chat that also picks up the phone.

Lumen is one embeddable AI widget that talks and types: a voice and chat agent that resolves, grounded in your content. Nothing else on the market ships voice and chat in one.

Voice + chat in oneEmbed anywhereAI-nativeOn every plan

RESOLVES, DOESN'T DEFLECT

Resolves. Doesn't deflect.

Most chat widgets match a question to a doc and hope. Lumen runs on Delyt's full agent engine. It searches your knowledge, follows your playbooks, takes action, and hands off to a human with full context when it should.

VOICE

Voice that feels human, not robotic.

Lumen speaks. Visitors talk; it listens, understands, and replies in natural speech, with instant acknowledgements so there is no dead air, and barge-in so they can interrupt like a real conversation. Same engine, same knowledge, same guardrails as chat.

WHY LUMEN

A voice + chat agent, grounded and governed.

Voice and chat, one widget

Visitors type or speak; Lumen answers either way in one natural conversation, with instant acknowledgements so there is no dead air. Embed it on your marketing site, docs, or app.

Grounded in your knowledge

Lumen uses semantic search across your knowledge base, returns only approved content, drops low-confidence matches instead of guessing, and cites every source. Your playbooks and guardrails apply automatically.

Your AI key, or ours

Lumen chat runs on your own OpenAI, Anthropic, or Google key at zero markup, or on Delyt credits. Lumen voice runs on Delyt credits.

Every answer is grounded in your approved content and cites its sources, so customers can verify and you stay in control.
