My Reincarnation with “Fluent English”
"Tenpera" is an AI-powered RPG adventure where English becomes your ultimate skill.
Stop memorizing textbook phrases you'll never use. Start speaking YOUR thoughts in English.
----- Tenpera's Revolutionary Method -----
1: Turn the sentences YOU want to say into English
2: Apply them through immersive gameplay
3: Deepen your knowledge as you adventure
The secret to language mastery? Learning what you actually want to say.
Things you care about stick in your memory 10x better than random textbook examples.
Tenpera combines 10+ AI features in a seamless ecosystem—from instant translation to battle systems to character interactions. This isn't "ask AI a question and get an answer." It's a complete language learning adventure you can't get anywhere else.
----- Your Learning Journey -----
1: Capture daily thoughts → AI instantly creates English flashcards you'll actually use
2: Battle monsters & build character relationships → Practice through addictive gameplay
3: Master the details → AI pronunciation, context-aware trivia, smart chat modes, and daily skill diagnosis
Plus, your "Memory Bank" stores favorite sentences, trivia, and idioms for easy review anytime.
----- Core Features Breakdown -----
● The Forging System: Turn Thoughts into Power
Got a thought? Turn it into an English card instantly. Every card becomes a weapon in your arsenal.
• Normal Forging: Input Japanese → Get complete English sentence cards
• Partial Forging: Specify an idiom or word → AI creates a full sentence around it
• Auto Forging: AI picks from 3,000+ idioms → Generates sentences automatically
• Manual Forging: Create cards by hand (free—no AI usage)
● Smart AI Enhancement
Every card gets AI-generated pronunciation audio + context-aware trivia that detects and explains key idioms automatically.
● RPG Progression: Level, Tier & Mana
Cards level up as you practice reading aloud and complete rearrangement quizzes. Longer sentences = higher Tier & Mana = more battle power. This naturally motivates you to tackle challenging vocabulary—not because you "should," but because it makes you stronger in-game.
● Six Specialized AI Chat Modes
Unlike generic AI chatbots, Tenpera splits conversations into six purpose-built modes to keep context clean and responses sharp:
• Question Mode
• English Sentence Correction
• Japanese ↔ English Translation (both directions)
• Casual Chat in English
• Casual Chat in Japanese
The problem with typical AI language learning? Long conversations pollute the context, degrading quality. Plus, typing prompts every time is tedious.
Tenpera's solution: Context only persists in casual chat modes. Other modes stay fresh. Plus, common prompts like "How do you say ~ in English?" are built-in shortcuts. In Question Mode, just type "futon" → tap the shortcut → get a detailed explanation instantly.
● Daily Skill Diagnosis Report
Once daily, receive your personalized "Chant Skill Diagnosis Report" that catches grammar gaps and tracks progress the Trivia feature can't cover. It even flags potential errors in AI-generated cards as a quality check.
● Ecosystem Features That Keep You Hooked
Tenpera isn't just flashcards—it's a living world with systems that naturally encourage daily engagement:
• Offering System: Sacrifice items/cards to power up Lexie, your guardian deity, for battle bonuses
• Rank System: Collect powerful cards to unlock prestigious titles
• Login Bonuses: Consecutive days = premium rewards
• Decay System: Unused items rot over time (use it or lose it!)
• Hunger System: Skip meals/water? Your stats drop
• Affinity & Time-Linked NPCs: Characters appear at different times in shops, guilds, and the Bureau of Reincarnation. Speak English to raise affinity and unlock new story events
Open the gateway to a new world with "Tenpera"!
