Site Context Chat adds a floating AI chat widget to your WordPress site. Visitors get instant answers grounded in your content — not generic ChatGPT small talk. When someone is ready, the bot can hand off a qualified inquiry to your team.

This plugin is the WordPress frontend. You connect it to a Supabase backend (database + edge functions) and your own Anthropic API key. No monthly SaaS fee to us — bring your own keys (BYOK).

Who is this for?

Agencies & developers who want a self-hosted, open-source chat stack for client sites
Service businesses that want discovery chat + lead handoff, not just a contact form
Teams comfortable with a one-time backend setup (~30–45 min) or working with a developer

Features

Floating chat widget (dark, light, or auto theme)
Chat admin page via shortcode [techlads_chat_admin]
Train the bot with markdown site context (services, FAQs, how you work)
Conversation history stored in your Supabase database
Inquiry / contact handoff when the visitor is ready
Embedded step-by-step setup guide in plugin settings
Open source — full backend code on GitHub

Important

The chatbot will not reply until you complete the backend setup (Supabase project, SQL migrations, edge functions, API secrets). The plugin settings page includes a full setup guide. Detailed docs: BACKEND-SETUP.md

Not included in this plugin

Anthropic API subscription / usage fees (paid by you to Anthropic)
Supabase project (free tier available)
Automatic indexing of WordPress posts — context is managed as markdown in the chat admin
