The only WordPress AI chatbot with Local Brain (zero API costs), Autopilot (site management), Empathy Engine (emotion-aware), and Glass Box (transparent AI).

== Description ==

**Sentient AI** is a revolutionary WordPress chatbot plugin that doesn't just answer questions — it *manages your site, learns from interactions, and respects privacy*. With Local Brain processing, WordPress Autopilot, emotion-aware AI, and transparent confidence scoring, it's the most powerful AI assistant for WordPress.

=== Why Sentient AI is Different ===

Unlike other chatbots that are black boxes, Sentient AI includes:

* **Widget Branding** — 6 preset themes, custom colors, border radius — match your brand perfectly
* **Local Brain** — Process FAQ answers locally in the browser. Zero API costs, full privacy, works offline.
* **WordPress Autopilot** — AI agent that manages your site: check updates, find broken images, create posts, scan security.
* **Sentient Memory** — Learns from every interaction, builds topic knowledge, and auto-generates FAQs.
* **Empathy Engine** — Detects user emotion (frustrated, confused, urgent, happy) and adapts AI response tone.
* **Glass Box Transparency** — Every response shows a confidence score (High/Medium/Low) and source attribution.
* **5 AI Providers** — OpenAI (GPT-4, GPT-3.5), Claude (Anthropic), Google Gemini, OpenRouter, Hugging Face.
* **Auto-Escalation** — Frustrated users and low-confidence answers automatically offer "Talk to a human".

=== Perfect For ===

* **SaaS companies** — Reduce support tickets with AI that understands user frustration
* **E-commerce stores** — Answer product questions with empathy during checkout issues
* **Agencies** — Deploy smart chatbots for clients with emotional intelligence
* **Membership sites** — Help members find answers without human support

== Installation ==

1. Upload the plugin folder to `/wp-content/plugins/sentient-ai`
2. Activate the plugin from the **Plugins** menu
3. Go to **Sentient AI → Settings** to configure your AI provider and API key
4. Enable the chatbot and customize the welcome message
5. Place `[sentient_ai_chat]` on any page, or use the floating widget

== Frequently Asked Questions ==

= Does this work without an API key? =

Yes! With Local Brain enabled, the chatbot answers FAQ questions locally without any API key. For AI-powered responses beyond FAQs, you'll need an API key from one of the supported providers.

= What makes this different from other chatbot plugins? =

**Everything.** Sentient AI has:
- Local Brain (zero-cost local processing)
- WordPress Autopilot (site management through chat)
- Sentient Memory (continuous learning)
- Empathy Engine (emotion-aware responses)
- Glass Box (transparent confidence scoring)
No other chatbot plugin has all of these.

= Does it work with WooCommerce? =

Yes! The chatbot works alongside WooCommerce. You can train the AI on your product pages and answer customer questions instantly.

= Can I use it without sending data to external APIs? =

Yes! Enable Privacy Mode in settings. The chatbot will only use your local FAQ database and never send data to OpenAI, Claude, or any external service.

= Does it slow down my website? =

No. The chatbot loads asynchronously in the footer. Local Brain assets (Fuse.js + local-brain.js) are only loaded when enabled and total ~8KB.

= How does Local Brain work? =

Local Brain uses Fuse.js for fuzzy search across your FAQ database. When a user asks a question, it searches locally in the browser first. If it finds a good match, it returns the answer without any API call. Falls back to cloud AI for unmatched queries.

= Can I customize the chatbot's appearance? =

Yes. You can change the welcome message, chat position (left/right), colors via CSS, and toggle confidence scores, source links, and sentiment indicators.
