Built for SA vs built for the US
iRainbow
iRainbow is built specifically for South African schools and families. CAPS and IEB aligned. Includes Afrikaans as a full subject and offers content in both English and Afrikaans. Lessons are taught by qualified SA educators who understand the local context and assessment style.
Khan Academy
Khan Academy follows US K-12 curriculum standards. The maths, science and history content is excellent but sequenced and presented for US schools. Standardised test prep is for US tests like SAT, AP, MCAT, LSAT, not South African matric exams. No Afrikaans content.
AI tutoring, included free vs paid extra
iRainbow
iRainbow's AI Tutor is included free in the R129/month subscription. It explains concepts in plain English, answers learner questions, and works inside the SA curriculum context.
Khan Academy
Khanmigo is Khan Academy's AI tutor, a paid extra at around $4 USD per month. It is a strong AI tutor, but conversation is geared to US-style learning content.
Matric and SA exam prep
iRainbow
iRainbow is designed around South African assessments, including primary school tests, FET phase exams, and matric. Lessons, practice questions and the Video Library all align to the topics, depth and style your child will see at school.
Khan Academy
Khan Academy's test prep features focus on US standardised tests (SAT, AP, MCAT, LSAT, Praxis Core). For SA matric or term tests, the topic match is unreliable.
When Khan Academy is the better choice
Khan Academy is genuinely excellent and is the better choice in some scenarios:
- If your family is moving abroad or your child is targeting a US university and US standardised tests.
- If you want a completely free option and are willing to manually map US topics to your SA curriculum.
- If you want extra international Maths or Science content beyond what is taught in school.
- For older learners and adults who want self-directed learning across topics not covered in SA schools.
For SA learners targeting matric and the SA curriculum at school, iRainbow is the better fit. Many families use both, Khan Academy for free international content, iRainbow for the SA curriculum.
Common Questions: iRainbow vs Khan Academy
Khan Academy is free and excellent, but it is built for the US curriculum and is not aligned to South African CAPS or IEB. SA learners can find that the maths topics, science notation, history examples and even the way concepts are introduced do not match what they encounter at school. iRainbow is fully CAPS and IEB aligned, available in English and Afrikaans, taught by SA teachers, and prepares learners for SA assessments and matric.
No. Khan Academy follows US K-12 curriculum standards. While much of the underlying maths and science is universal, the structure, sequence, exam prep and examples are not designed for South African schools. iRainbow is built specifically for the SA curriculum.
Khanmigo is Khan Academy's paid AI tutor, around $4 USD per month. It is a strong tool, but conversation is in English only and aligned to US-style learning. iRainbow includes a free AI Tutor specifically tuned for SA learners, in plain English, working alongside the SA curriculum.
No. Khan Academy does not offer Afrikaans content or teach Afrikaans as a subject. iRainbow includes a full Afrikaans subject from Grade 1 to 12 and offers all platform content bilingually in English and Afrikaans.
Yes, many SA families use Khan Academy as a free supplement for additional Maths and Science content (international perspective), while using iRainbow as the structured CAPS and IEB aligned learning path their child needs for school.
Yes, iRainbow is month-to-month at R129 with no annual lock-in, plus a 30-day money-back guarantee.
