Create an assignment

One prompt.A ready assignment.

Hahlex drafts it from your own material. You publish it to the whole class.

Ask Hahlex anything

Prompt example: Create a 10-question assignment on the present perfect for the whole class.

Generated assignment: Present perfect: since / for (Whole class · 18 learners · 10 questions · Due Fri 23:59 · Source: Unit 4 Present perfect.pdf)

  1. Fill in the blank: I ___ (live) in Hà Nội since 2021.
  2. Single choice: She has worked here ___ five years.
  3. Matching: Match each time phrase with since or for.
  4. Ordering: Put the words in order: yet / finished / you / have / ?

Personalise assignment for each learner

Every learner getsthe version they need.

One prompt and Hahlex reads every learner profile, sends each learner questions aimed at their own gap, then marks the work.

Ask Hahlex anything

Prompt example: Personalise Present perfect practice for each learner in Giao tiếp A2.

Stages: Personalised → Sent → Learners working → Auto-marked

  • Foundation tier (8 questions · since / for · have + past participle · Single choice · Fill in the blank): Bùi Ngọc Diệp (gap: since / for, auto-marked score: 6/8); Lý Bảo Châu (gap: have + past participle, auto-marked score: 5/8)
  • Core tier (10 questions · Irregular participles · present perfect vs past simple · Fill in the blank · Matching · Short answer): Lê Khánh Chi (gap: irregular participles, auto-marked score: 8/10); Trần Minh Anh (gap: ever / never / yet, auto-marked score: 9/10); Phạm Đức Huy (gap: present perfect vs past simple, auto-marked score: 8/10)
  • Stretch tier (6 questions · Present perfect continuous · mixed-tense writing · Ordering · Short answer): Nguyễn Gia Hân (gap: present perfect continuous, auto-marked score: 6/6); Võ Thảo Linh (gap: writing with mixed tenses, auto-marked score: 5/6)

Outcome after auto-marking: Class average 79%, Present perfect mastery rose from 48% to 71%, most missed topic: since vs for.

Learner profile

A profile builtfrom every answer.

Hahlex names the mistake behind a falling score, summarises it in plain words and suggests the next step. One click turns that into the next personalised assignment.

Ask Hahlex anything

Prompt example: Show me how Bùi Ngọc Diệp is doing this month.

Learner: Bùi Ngọc Diệp (Giao tiếp A2 · Grade 5 · Average mark 6.8 · Built from 38 answers across 5 assignments)

  • Past simple: 82% (Steady)
  • Irregular verbs: 66% (Improving)
  • Present perfect: 46% (Declining)
  • since / for: 40% (Needs attention)
  • Writing · sentence structure: 58% (Steady)

Mistake pattern: Switches to past simple when a time phrase appears — “I lived → have lived here since 2021.” (6 of 8 errors this month).

AI summary: Diệp is solid on past simple but slips back into it with since / for. Practise those first, then short writing.

Suggested next step: 8 short questions on since / for · Foundation · about 10 min (Approve & assign in one click).

FAQ

Questions, answered.

  • What is Hahlex Education?

    Hahlex Education is the AI operating system for education centres and schools in Vietnam. It connects teachers, learners, parents, administration and data around one shared Learner Intelligence Layer so every department works from the same profile of each student.

  • How does Hahlex create and personalise assignments?

    With one prompt, a teacher drafts an assignment directly from their own teaching materials (such as PDFs, workbooks or slides) and publishes it to the whole class. With one more prompt, Hahlex reads every learner profile, groups students into Foundation, Core and Stretch tiers aimed at their specific knowledge gaps, and automatically marks submissions.

  • How does the Hahlex learner profile work?

    Hahlex builds a live competency profile from every answer a learner submits across homework, quizzes and classwork. Instead of only showing a falling grade, Hahlex identifies the exact mistake pattern (for example, switching to past simple after 'since' and 'for'), summarises it in plain language for the teacher, and turns the suggested next step into a targeted practice assignment with one click.

  • What can teachers and centre managers ask Hahlex?

    Teachers and managers can ask their centre anything in plain language, such as 'How is the centre doing this month?', 'Show me enrolment by campus', 'Which classes need attention this week?', 'Which assignments haven't been submitted?' or 'Draft a note to parents about next week's test', and get immediate, source-cited answers from attendance, gradebook and enrolment data.

  • Does Hahlex replace teachers or keep teachers in control?

    The teacher always stays in control. Hahlex drafts assignments, personalises practice tiers, flags early learning gaps and prepares parent updates, while six AI agents handle routine operational tasks. Nothing is published or sent to learners or parents until the teacher reviews, edits if needed, and approves it.

  • How are Hahlex Education and Hahlex Studio related?

    Both are part of Hahlex and are built by the same founding team. Hahlex Education, at hahlex.com, is the AI operating system for education in Vietnam. Hahlex Studio, at portfolio.hahlex.com, is the team's engineering studio: it builds AI agents, workflow automation and custom software for operators outside education.

  • Hahlex là gì và giải quyết bài toán nào cho trung tâm giáo dục tại Việt Nam?

    Hahlex là hệ điều hành AI dành cho các trung tâm ngoại ngữ, trung tâm bồi dưỡng và trường học tại Việt Nam. Hahlex xóa bỏ tình trạng vận hành phân mảnh (nhiều nhóm chat, bảng tính rời rạc, dữ liệu tách biệt) bằng cách kết nối giáo viên, học viên, phụ huynh và bộ phận vận hành quanh một hồ sơ năng lực duy nhất của từng học viên, giúp phát hiện lỗ hổng kiến thức sớm, giao bài tập cá nhân hóa chỉ với một câu lệnh (prompt) và tăng tỷ lệ chuyển đổi tuyển sinh.
