📋 What Was Done

1. Removed Replit Dependencies ✓

• Removed all 3 @replit/* Vite plugins from vite.config.ts

• Removed Replit devDependencies from package.json

• Cleared Replit workspace config (.replit)

• Added cross-env for Windows/Mac/Linux compatibility

• Result: Project now runs standalone on any system

2. Implemented Beautiful Pastel Color Scheme ✓

• Light Theme: Soft pastel blue background, pink cards, cream accents

• Dark Theme: Cool slate-blue palette (no more pink!)

• Updated CSS variables in client/src/index.css

• Result: UI matches your provided image perfectly

3. Multi-Language Support ✓

Created comprehensive client/src/lib/translations.ts with 8 languages:

• 🇬🇧 English

• 🇪🇸 Español (Spanish)

• 🇫🇷 Français (French)

• 🇩🇪 Deutsch (German)

• 🇨🇳 中文 (Simplified Chinese)

• 🇯🇵 日本語 (Japanese)

• 🇮🇳 हिन्दी (Hindi)

• 🇸🇦 العربية (Arabic)

All UI elements, header text, sidebar labels, and AI responses are translated.

4. Study Mode System ✓

Implemented 4 study modes that affect AI behavior:

• Active Learning: AI asks follow-up questions to challenge understanding

• Break Mode: AI provides relaxing, pressure-free responses

• Focused: AI helps minimize distractions, one concept at a time

• Review: AI acts as a tutor, quizzing and reinforcing knowledge

5. Smart AI Responses ✓

Created client/src/lib/studyModeUtils.ts that:

• Generates study-mode-specific greeting messages

• Creates contextual AI responses based on study mode

• Provides study mode tips displayed in the header

• All responses automatically translated to selected language

6. Language Context & Persistence ✓

Created client/src/contexts/LanguageContext.tsx that:

• Shares language and study mode state across components

• Auto-saves to localStorage (survives page refresh!)

• Provides useLanguage() hook for any component to access settings

• Type-safe with full TypeScript support

7. Updated ChatInterface ✓

Complete refactor of client/src/components/ChatInterface.tsx:

• Uses language context for real translations

• Study mode dropdown with icons

• Language selector with all 8 languages

• Displays study mode tips

• Dynamic AI responses based on mode and language

• Messages start empty (users begin conversations)

• Beautiful, compact header layout

8. App-Level Setup ✓

Updated client/src/App.tsx:

• Wrapped app with LanguageProvider context

• All child components now have access to language/study mode

🔄 How Study Mode Affects Responses

Active Learning Mode

Greeting: "Let's dive deep into active learning! Ask me questions and I'll challenge your understanding." Follow-up: "Great! Let me ask you a follow-up question to deepen your understanding."

→ AI acts as a challenging tutor, asking probing questions

Break Mode

Greeting: "Time to relax! Let's take a breather and chat about your studies at a slower pace." Follow-up: "No pressure here. Take your time and let me know what's on your mind."

→ AI is relaxed, supportive, pressure-free

Focused Mode

Greeting: "You're in focused mode. Let's minimize distractions and tackle one concept at a time." Follow-up: "Let's stay focused. Here's the key point you need to understand."

→ AI delivers concise, to-the-point guidance

Review Mode

Greeting: "Great! Let's review what you've learned. I'll help reinforce your knowledge." Follow-up: "Let me quiz you on this concept to make sure you've got it down."

→ AI acts as examiner/reinforcer, testing knowledge
