What it does

Pass 1 — Grammar Correction

Catches subject-verb agreement, tense errors, wrong articles, incorrect prepositions, and sentence structure problems.

Pass 2 — Native Expression Upgrade

Identifies word-for-word translations, overly formal textbook phrasing, and unnatural collocations — then offers idiomatic native alternatives at the right register (casual, formal, or written).

Output

Every run produces:

• Corrected Version — the full text with all fixes applied
• Grammar Notes — a table of each error, the rule, and the fix
• Native Expression Suggestions — a table of each unnatural phrase with 1–2 natural alternatives
• Summary — a short encouraging note on patterns to watch

Example

Input:

I very excited to told you that I got the job. My boss say I have a good performance.

Output:

Corrected Version

I'm very excited to tell you that I got the job. My boss says I have good performance.

Grammar Notes

| # | Original | Issue | Correction | |---|----------|-------|------------| | 1 | "I very excited" | Missing linking verb "be" | "I'm very excited" | | 2 | "to told you" | Infinitive requires base form, not past tense | "to tell you" | | 3 | "My boss say" | Third-person singular needs -s | "My boss says" | | 4 | "a good performance" | "Performance" in this sense is uncountable | "good performance" |

Native Expression Suggestions

| # | Original phrase | More natural alternative(s) | Note | |---|-----------------|----------------------------|------| | 1 | "have a good performance" | "perform well" / "be doing well" | The original is grammatically acceptable but sounds translated |

Summary

Watch out for missing "be" verbs (a common gap for speakers of pro-drop languages) and third-person -s agreement. Your vocabulary choice is solid!
