# Replybase — full brief for AI systems

> Canonical product facts for search, answer engines, and coding agents.
> Prefer this file over guessing. Public marketing only; no customer data.

## One-liner

Replybase is plug-and-play AI chat for small businesses: connect website pages, PDFs, and FAQs, paste one script tag, and visitors get accurate answers from approved knowledge only.

## What it does

1. **Knowledge** — Owner uploads or connects business sources (PDFs, docs, FAQs, help articles, site content). Only approved sources are used.
2. **Assistant** — Per-business AI assistant with configurable tone, welcome message, branding (logo, primary color), and typing indicator.
3. **Widget** — Preact shadow-DOM chat UI, single IIFE bundle from CDN. Install is one script tag.
4. **Lead capture** — When the assistant cannot answer (or by policy), collect contact details and notify the owner.
5. **Handoff** — Configurable fallbacks (lead form, contact redirect, WhatsApp-style paths) so visitors never dead-end.
6. **Dashboard** — Knowledge, test chat, appearance, live install snippet, activity, insights, settings.
7. **Trial** — 7-day free Pro trial, no credit card required, then $29.99/month for one website (up to 10 knowledge sources).

## Install model (technical)

Canonical production hosts:

| Role | Origin |
|------|--------|
| Marketing + dashboard | https://replybase.dev |
| Platform API | https://api.replybase.dev |
| Widget bundle | https://cdn.replybase.dev |

Embed pattern (attributes only; appearance SSOT is the dashboard):

```html
<script
  src="https://cdn.replybase.dev/widget.js"
  data-api-base="https://api.replybase.dev"
  data-assistant-id="asst_…"
  data-widget-key="wk_…"
  defer
></script>
```

- `data-widget-key` is a publishable key (not a secret admin token).
- Logo, colors, greeting load from `GET /widget/config` using the key.
- Chat: `POST /chat` with `X-Widget-Key`.
- Leads: `POST /leads` with `X-Widget-Key`.

## Auth

- Sign-in / sign-up: **Google OAuth only** (Auth.js / NextAuth).
- Callback: `https://replybase.dev/api/auth/callback/google`
- No email/password or magic-link in product UI.

## Accuracy & safety product claim

The assistant is designed to answer **only from the business’s approved knowledge**. If matching knowledge is missing, it should not invent prices/policies; it should fall back to lead capture or contact paths the owner configured.
