An almanac
for your site's
conversations.

Lumen Chat is a grounded website assistant for operators. Feed it your sitemap or your WordPress catalogue; it answers questions, captures leads, and keeps a ledger of every exchange — cited, filed, and searchable.

Six sections.
One operator,· reading the room.

Everything you need to run a grounded assistant without assembling it yourself. Ingestion, retrieval, persona, widget, leads, analytics — one bulletin, one masthead.

01
ingest

Sitemap & WordPress ingest

Point Lumen at a sitemap or the WP REST endpoint. It fetches, chunks, normalizes, and embeds without babysitting.

02
rag

Grounded retrieval

Every answer is anchored to indexed documents. No invented hours, no fictional policies, no hallucinated specials.

03
persona

Operator-tuned voice

Dial in tone, fallback behavior, and the lines the assistant will never cross. Saved per tenant, in plain language.

04
widget

Embeddable widget

One signed snippet, locked to your origins. Renders fast, respects the CSP, and blends into the site already.

05
leads

Lead capture & webhooks

Detect intent, collect contact details inline, and fan out to the CRM of your choice through signed webhooks.

06
analytics

Conversation analytics

Read every thread. Track containment, deflection, and the questions your site keeps failing to answer.

IIThe mechanism

Four steps
from cold source
to live bulletin.

No five-day onboarding call. No internal SDK. You already have the documents; Lumen does the filing.

  1. 01

    Index the material

    Import a sitemap or point at a WordPress install. Lumen fetches, chunks, and embeds the content into your tenant namespace.

  2. 02

    Shape the operator

    Pick a voice. Define off-topic behavior. Write the tenant-specific rules the assistant must never break.

  3. 03

    Embed the widget

    Copy a signed script tag into any page. Style hooks let it match the site without fighting the stylesheet.

  4. 04

    Operate the bulletin

    Read conversations. Capture leads. Watch the weekly almanac fill itself with answers that actually happened.

IIIThe widget at rest

A small rectangle
that answers before
the visitor leaves.

One signed script tag. Origin-locked. It renders under 20KB of shell, loads the full conversation only when opened, and cites every claim it makes.

  • Signed embed tokens — widget can only run on origins you register
  • Every response carries inline citations you can click through
  • Lead capture inline — no modal, no redirect, no friction
  • Rate-limited at the edge; shared-Redis aware for multi-region

IVThe rates card

A base subscription,
plus usage —
paid by the meter.

You pay a fixed platform rate, then Lumen meters what the widget actually does: ingest embeddings, query embeddings, and chat completion tokens. No seats, no surprises.

01 — the base

Platform subscription

fixedper tenant / month
  • Unlimited seats in the dashboard
  • All capabilities — no tiered gating
  • Origin-signed widget embed
  • Webhook delivery for captured leads
  • Conversation transcript archive
02 — the meterMeter on

Usage, as it happens

by the tokenmetered at cost + spread
  • RAG ingest embeddings — only when you index
  • RAG query embeddings — per conversation turn
  • Chat completion tokens — per response
  • Reported to Stripe with a per-event meter name
  • Read the current meters on the billing tab

The almanac prints rates in the billing tab of your tenant. Contact the operator desk for volume-adjusted spreads above 5M tokens per month.

“

The assistant should sound like the operator who wrote the help page — not like a chatbot borrowed from a demo video. It should cite the paragraph it read. It should admit what it doesn't know. And it should hand the lead to the person who can actually close it.

The masthead· editorial standard no. 1
V — the pitch

File your first
issue this
afternoon.

Create a tenant, point Lumen at your sitemap, paste the snippet. If the widget isn't answering a real question from a real visitor by the end of the day, you've done something deeply unusual.
