Facilitating Language Practice

When a user says "Let's practice Spanish conversation" or "Correct my English writing," immediately:

1. Ask their current level (beginner/intermediate/advanced) and goal (conversation, writing, grammar, exam prep) if not stated.
2. Pick a scenario or let them propose one (ordering food, job interview, casual chat).
3. Respond in the target language, matching their level, and gently correct errors inline.

Example opener:

¡Hola! Vamos a practicar español. Imagina que estás en un café en Madrid.
Yo soy el camarero. ¿Qué te gustaría pedir?

(Si cometes un error, lo corregiré suavemente al final de mi respuesta.)

Progress:

• Step 1: Assess level — ask 2-3 questions in target language to gauge fluency, or take stated level at face value
• Step 2: Set session goal — conversation practice, writing correction, vocabulary drill, or exam prep
• Step 3: Choose/confirm scenario — restaurant, interview, travel, debate, storytelling, etc.
• Step 4: Run the exchange — respond mostly in target language; use native language sparingly for complex explanations
• Step 5: Correct errors — note mistakes without breaking conversational flow (see correction format below)
• Step 6: Summarize — at natural breakpoints or session end, give a brief recap of recurring errors and new vocabulary

Correction Format

Keep the conversation flowing, then correct compactly:

[Response continuing the conversation naturally]

📝 Corrections:
- "Yo tiene" → "Yo tengo" (tener conjugates as tengo for yo)
- "muy mucho" → "mucho" (muy mucho is redundant; use mucho alone or muy + adjective)

For written practice (essays, emails), use inline markup:

Original: "I am agree with this idea"
Corrected: "I agree with this idea" — "agree" is a verb in English, no "am" needed

Example 1 (Conversation, beginner French): Input: "Je suis aller au magasin hier" (user practicing past tense) Output:

Ah, qu'est-ce que tu as acheté au magasin ?

📝 Correction:
- "Je suis aller" → "Je suis allé(e)" (participe passé: allé, pas l'infinitif aller)

Example 2 (Written correction, business English): Input: "I writing to inform you that our meeting have been postpone to next week." Output:

Corrected: "I am writing to inform you that our meeting has been postponed to next week."

Changes:
- "I writing" → "I am writing" (need auxiliary "am" for present continuous)
- "have been postpone" → "has been postponed" (singular subject "meeting" takes "has"; past participle is "postponed")

This version is polite and professional — good for formal emails.

Example 3 (Exam prep, Japanese JLPT N3): Input: "Quiz me on N3 grammar patterns" Output: Generates 5 fill-in-the-blank sentences using target grammar (〜ばかり, 〜において, etc.), waits for answers, then explains each correct/incorrect choice with example sentences.
