IELTSbiz vs
IELTS Liz

IELTSbiz is an AI-powered IELTS preparation platform built around one idea: measured progress you can trust. It covers all four papers. Reading and Listening are written fresh rather than drawn from a bank of past papers, and are marked against an answer key — the same answers always produce the same band, so a rise in your score is progress rather than a different marker on a different day. Writing and Speaking are marked criterion by criterion for an estimated band — accurate enough to aim at, and reported as an estimate rather than an examiner’s verdict.

Reading goes deepest, because it is where most candidates quietly lose marks. Every wrong answer is labelled with the trap that caused it — Partial Truth, Extreme Language, Opposite Meaning, Outside Text, Distractor Word or Temporal Confusion — and shown beside the line of the passage that settles it. Your estimated band is then tracked separately for each of the 11 reading question types, so “reading is my weak skill” becomes “Matching Headings is my weak type”. When you want the whole paper, there is a full 40-question Reading test under a 60-minute clock, and a guided four-skill mock.

That measurement focus runs through everything we build. Our AI grading was validated in a study of 1,200 Writing Task 2 essays against certified examiners, and every guide on the site is written by our named editorial team and checked against official sources — you can read exactly how in our editorial policy. We sell trust and measurement, not hype: no band guarantee, and no accuracy percentage we have not published the method for.

What costs nothing: all four papers, within an allowance. Reading and Listening practice are free every day with full trap-level feedback, and Writing and Speaking are marked against the official criteria free every month. A 7-day trial raises those allowances rather than being the only thing that unlocks them — when it ends they drop back, they do not drop to zero. The one exception is the Band 8 Writing Trainer, whose marking is Pro only and which the trial does not include. Pro is $6.99/month or $29 once for lifetime access. The band-score calculator, the daily Word Coach and the Speaking cue cards are free to use. IELTSbiz is independent and is not affiliated with IDP, the British Council, or Cambridge, who jointly own and deliver the IELTS test.
