What is ReplyJet?

ReplyJet detects the intent behind every customer message and generates a short, human, Egyptian-Arabic (or English) reply — instantly. No fluff. No robotic phrasing.

Intent	Trigger signals	What happens
😤 Angry / Complaint	زعلان، غلط، هشتكي، angry, complaint, refund	Structured apology → action → order request
💰 Sales / Close Sale	بكام، سعر، متاح، price, how much, available	Price/availability first → value → CTA
📩 Follow Up	manual mode	Warm re-engagement → soft CTA
💬 Normal	anything else	Direct, short answer

---

Features

• Intent detection — auto-detects angry / sales / normal from message content
• Mode selector — override intent manually: Auto / Complaint / Close Sale / Follow Up
• Structured Egyptian Arabic — sounds like a real human, not a chatbot
• Multiple tones — professional, friendly, sales
• Bilingual — Arabic (Egyptian dialect) + English
• Copy button — one-click reply copy with 2s confirmation
• Regenerate button — get a new reply without clearing the current one
• Intent badge — shows detected intent on every reply
• RTL layout — Arabic replies render right-to-left automatically
• History — last 50 replies saved locally with intent + mode
• Settings — default tone, language, and max tokens
• Keyboard shortcut — Ctrl+Enter to generate

How It Works

User input + Mode selection
   ↓
Mode === "auto"?
   ├── YES → detectUserIntent()   — keyword scan → angry | sales | normal
   └── NO  → use mode directly    — complaint | close_sale | follow_up
   ↓
buildSystemPrompt()    — structured prompt per intent + language + tone
   ↓
Groq API  (llama-3.1-8b-instant, temp=0.3, max_tokens=60–400)
   ↓
{ reply, tone, language, intent, mode } → UI → History
