Zoju - Language feedback that remembers your mistakes

Hi Product Hunt, I’m Ankush, co-founder of Zoju. We built Zoju because serious language learners often practise a lot but still don’t know what is actually holding them back. We’re starting with IELTS. Reading and Listening are easier to check because there are answer keys, but Writing and Speaking are much harder to self-evaluate. Most tools grade one attempt and forget the learner. Zoju helps learners practise all four skills, get feedback on their answers, and track recurring mistakes across sessions. Instead of only seeing one score from one attempt, learners can see the patterns they keep repeating and what to practise next. Zoju is free to try: unlimited Reading and Listening practice, plus 2 free Writing and Speaking evaluations. We’re launching today as part of the YC Application initiative. Would love feedback, especially from anyone who has taken IELTS, TOEFL, PTE, or helped someone prepare.
