"Discuss" doesn't take "with you" here, and days of the week use "on". "Would like" sounds more polite in business emails.

Why learning English at work is hard

Millions of Vietnamese professionals need English for their jobs, but traditional options don't fit a busy schedule.

Tutors are expensive

Regular one-on-one lessons cost more than most learners can afford long-term.

No real feedback

Apps teach vocabulary, but rarely tell you what's wrong with the email you're about to send.

Progress is invisible

Without clear levels and tracking, learners lose motivation and stop.

How Harapi works

A structured curriculum plus an AI coach that grades every answer against clear CEFR-aligned rubrics.

01

Structured curriculum

Lessons organised by CEFR level (A2–C1) around real workplace situations: emails, meetings, presentations, interviews.

02

AI grading & feedback

Submit writing or speaking. Get scores for grammar, vocabulary, coherence and tone — with explanations in plain language.

03

Personalised practice

Exercises are generated from your own mistakes, so every session targets what you actually need.
