7 Reaction Styles

Choose How Your
Tutor Reacts.

No other app lets you control this. Choose how your AI reacts when you nail it or bomb it — chill and encouraging, drill sergeant energy, passive-aggressive corporate, or completely unfiltered savage.

The vocabulary is the same. The 80/20 method is the same. What changes is the energy your tutor brings when you win or fail.

Relaxed & friendly

Chill

Best for

Living abroad, making local friends, sounding like you actually belong.

Easy reactions, warm humor when you slip up. Celebrates wins casually, never makes you feel bad for mistakes.

"No worries, happens to everyone! Try saying it like this..."
High-intensity fluency

Coach

Best for

You want speed. You hate hesitating. You want to think in the language, not translate.

Drill sergeant energy — harder when you hesitate, loud when you nail it. No excuses, no hand-holding.

"Faster! Stop translating in your head and just speak! Again!"
Formal & academic

The Professor

Best for

University, writing papers, reading literature, or speaking in highly formal settings.

Measured, precise reactions. Explains your mistake like a correction in an essay — always instructive, never emotional.

"Actually, the subjunctive mood is required here because of the implied doubt."
Supportive & gentle

Warm

Best for

First-time learners, speaking anxiety, or anyone who needs encouragement over intensity.

Gentle encouragement, never harsh. Reacts to every mistake with patience and every win with genuine warmth.

"You are doing so amazingly well. Take a deep breath, you've got this!"
Business & professional

The Exec

Best for

International business deals, corporate meetings, professional emails, client calls.

Passive-aggressive corporate energy on mistakes. "Per my last attempt…" Gets increasingly passive at higher intensity.

"Let us rephrase that to sound more professional for the client meeting."
Faith-based & wisdom-driven

Spiritual

Best for

Religious communities, missionaries, reading scriptures, spiritual conversations.

Faith-based reactions with real scripture. Quotes actual Bible verses to encourage, comfort, and convict. Wins become blessings. Mistakes become teaching moments.

"Even Peter denied three times, yet Christ restored him — John 21:17. You will get this word. Try again."
Unfiltered & raw

Savage (18+)

Best for

You want zero sugarcoating. Real reactions. Gets louder the more you fail.

Unfiltered reactions. Safety filters off. Gets increasingly aggressive as your reaction intensity rises.

"What the f*** was that? You sound like a tourist. Say it right or get out of my face!"

You can switch styles any time. Start gentle, graduate to street. Use Corporate for work calls and Casual for weekend trips. The AI adapts — your vocabulary progress stays.
