Add a GDPR-compliant AI chat widget to your WordPress site that answers visitor questions automatically.

== Description ==

Demitr adds an AI chat widget to your WordPress site. The AI answers visitor questions about your business — hours, services, prices, location — because you tell it what to say.

= Why Demitr? =

* **Knows your business** — Enter your details once, the AI handles the rest
* **GDPR by design** — Consent gate, no cookies, no persistent storage, PII anonymization
* **EU-sovereign AI** — Powered by Mistral (Paris). Hosted on Hetzner (Germany). Data stays in the EU
* **30-second setup** — Install, enter your info, enable. Done
* **6 European languages** — English, French, German, Dutch, Italian, Spanish. AI responds in the visitor's language
* **Customizable** — Brand name, accent color, position, language

= Two Modes =

**Free mode:** Configure business details in WordPress admin. The AI uses them to answer questions.

**Paid mode:** Enter your API key from [demitr.ai](https://demitr.ai). Widget config is managed from the dashboard.

= External Service =

This plugin sends chat messages to the Demitr API for AI processing. You configure the endpoint in Settings > Demitr Chat.

* **Default endpoint:** [demitr.ai](https://demitr.ai)
* **Provider:** dcode technologies S.a r.l., Luxembourg
* **Terms of Service:** [demitr.ai/terms](https://demitr.ai/terms)
* **Privacy Policy:** [demitr.ai/privacy](https://demitr.ai/privacy)

**Data sent:** visitor message (PII tokenized), session ID (random UUID), business context, consent flag.
**Data NOT sent:** IP address, cookies, personal identifiers, browsing history.

You can self-host the API for full data control by configuring the API endpoint URL in the plugin settings.

== Installation ==

1. Upload the plugin to `/wp-content/plugins/demitr/` or install via Plugins > Add New
1. Activate the plugin
1. Go to Settings > Demitr Chat
1. Enter your API endpoint URL (or use the default demitr.ai)
1. Fill in your business name, type, hours, and services
1. Check "Enable Widget" and save

== Frequently Asked Questions ==
