Stop guessing
why you're stuck
at Band 6.5

Zoju's AI shows the exact patterns holding your score back — across reading, writing, listening, and speaking.

A System, Not a Question Bank

Other apps hand you another question. Zoju finds exactly why your score isn't moving and what to work on next.

Practise your way illustration

Practise your way

Pick one skill or all four. Strict mode for test pressure, Breath mode when you're still learning.

Feedback that explains illustration

Feedback that explains

Not just a model answer. We break down each criterion, what you missed, and the pattern behind it.

Watch scores grow illustration

Watch scores grow

Your dashboard tracks every session. See what you've fixed and what's still costing you marks.

How Mistake Memory works

Most apps grade your test. Zoju learns where you keep slipping — and tells you the moment the pattern shows up again.

  1. Step 1

    Detect

    Every session, Zoju watches for the slips that keep costing you marks — a missing article, a vague topic sentence, a Part 2 trail-off.

  2. Step 2

    Tag

    Patterns get tagged across all four skills — the same weak spot in writing and speaking becomes one thing to fix, not two.

  3. Step 3

    Coach

    Next time the pattern shows up, Zoju flags it before you submit — with the rule that fixes it. Mistakes you stop making.

Built for Exam Day. Nothing Else.

Most apps show you a score and move on. Zoju breaks down every response by criterion, finds your recurring mistakes, and tells you what to fix.

Still learning or ready to test?

Two modes, two purposes. Breath mode lets you slow down and learn. Strict mode removes all aids so you see where you actually stand.

Know what’s wrong. Watch it disappear.

Zoju spots the mistakes you keep repeating and tells you when they stop. You see both sides so you know what's working.

Scoring breakdown illustration showing criterion-level analysis

Scores that break down the why

Every score breaks down by criterion so you understand the number, not just see it. Built on IELTS-style band descriptors — a practice estimate, not an official result.

Feedback illustration showing targeted improvement on your own response

Improve your answer, not just giving models

We take your answer and show you how to make it stronger. Better vocabulary, clearer structure, higher band.

Listening practice illustration with real exam audio conditions

Train your ear

Real listening practice with the clock running. No subtitles, no shortcuts. The same pressure you'll face on test day.

Not All Preparation Is Equal

A tutor depends on who you get. ChatGPT wasn't built for exam prep. Zoju was built for one purpose and it shows.
