Cathoven is an AI-powered platform best known for scoring Writing and Speaking against the official criteria, with a free tier that caps how many AI scorings you can run per day. It does that job well. But candidates whose bottleneck is Reading tend to want three things it is not built around:
IELTSbiz generates a brand-new, Cambridge-difficulty passage every time you practise, so you never run out of material or end up re-reading a set whose answers you half-remember.
Matching Headings behaves nothing like True/False/Not Given. IELTSbiz lets you isolate any of the 11 reading question types and drill it until it stops costing marks — not just sit whole tests.
Cathoven’s free tier limits daily AI scorings. IELTSbiz is free to start with generous reading practice, so a long study session is never cut short by a counter.

IELTSbiz generates a completely fresh passage every session, drawn from AI trained on thousands of academic texts — infinite unique reading practice at your chosen topic and band level.
IELTS Reading answers are wrong for a reason the examiner designed: Partial Truth, Extreme Language, Outside Scope, Opposite Meaning. IELTSbiz labels the trap so you stop repeating the mistake — not just a right/wrong key.
Instead of one overall figure, IELTSbiz tracks your estimated band for each of the 11 reading types, so you know exactly which type to prioritise next.
Many candidates pair Cathoven’s AI Writing and Speaking scoring with IELTSbiz for deep, unlimited reading drilling and a free Writing Checker — the two complement each other.
IELTSbiz is an AI-powered IELTS preparation platform built around one idea: measured progress you can trust. Rather than a fixed library of recycled tests, it generates fresh, Cambridge-style reading passages on demand and explains the specific trap behind every wrong answer — then tracks your band separately for each of the 11 reading question types, so you always know exactly what to work on next.
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.
Alongside reading practice, IELTSbiz includes a free AI Writing Checker, a band-score calculator, a daily Word Coach, and an expanding library of Speaking cue cards and test guides. The core tools are free to start with no credit card required; Pro (from $6.99/month or $29 lifetime) removes limits when you are ready. IELTSbiz is independent and is not affiliated with IDP, the British Council, or Cambridge, who jointly own and deliver the IELTS test.
