01/The verdict

An IELTS practice site with 80+ free Reading and Listening tests, plus AI band estimates and error notes on Writing and Speaking. Test-takers pay $6.50 a week or $20 a month.

What Zoju sells is a set of practice tests plus LLM grading against the public IELTS band descriptors. A builder with Claude Code can reproduce that in a couple of weeks. I found no founder audience, no funding, no reviews and no traction beyond a directory listing. The British Council badge is the open referral affiliate programme in Thailand, which anyone can apply to. The market is packed with AI graders, and some are funded, so a newcomer's only real hurdle is writing 80+ test sets and earning SEO, and it is starting from the same place.

Distribution

Shallow

~3 mo to cross

Zoju publishes indexable free test pages like /free-ielts-listening-tests/set-21 aimed at 'free IELTS practice' searches. I found no sign that they rank above established sites like ieltsonlinetests.com.

To cross it: Generate or commission 80+ original Reading and Listening sets with TTS audio and publish them as SEO pages.

Exclusive access

Shallow

~2 mo to cross

Zoju shows a British Council IELTS Referral Partner badge. Its footer says this is the referral programme in Thailand only, which is a commission-based affiliate scheme.

To cross it: Apply to the British Council or IDP affiliate programme in any country.

03/The gap

Easy to copy

LLM grading of Writing and Speaking against the public IELTS band descriptors
Practice Reading and Listening tests with answer keys and transcripts
Progress dashboard and recurring-mistake tracking
Pricing at $20 a month, framed against a $300 retake

How you'd go after it

Go local and in-language for Vietnam, India or China with local payment rails and much lower prices, the way Prep Edu won Vietnam
Run the whole funnel through TikTok and YouTube Shorts with an ex-examiner persona, since Zoju has no visible audience
Offer human examiner review on top of AI grading as a trust upsell that ChatGPT-style graders can't match
Sell to coaching institutes as a white-label grading tool for B2B volume

04/Build against it?

Stay away

There are dozens of AI IELTS graders, Prep Edu has raised $7M and claims 1M learners, and ChatGPT is the free default. Only enter with a distribution edge you already have, such as an IELTS creator audience or ties to coaching institutes.
