Before you decide.
Honest answers about what CertiLang does — and what it doesn't.
View all questionsWill this actually help me pass?
CertiLang focuses on what matters: we show you exactly where you're losing marks and help you fix those specific problems before exam day. Our AI gives feedback on every answer so you learn from each mistake.
I've tried other apps and still failed. How is this different?
Most apps teach vocabulary or grammar in isolation. CertiLang diagnoses your actual weak points, gives specific feedback on your writing and speaking, and builds your study plan around what's costing you marks not generic exercises.
Is €9.90/month worth it when there's free content online?
You can prepare with free resources, but CertiLang is designed for learners who want personalized AI feedback, structured exam practice, and everything they need to prepare in one place.
What if I'm already studying with a teacher?
CertiLang complements teacher instruction perfectly. Use it for unlimited practice and feedback between lessons. Your teacher handles conversation and motivation; CertiLang handles repetition and correction at scale.
I only have 4 weeks until my exam. Is that enough time?
Yes. CertiLang's diagnostic shows your weak points immediately, so you focus on what matters most. Many learners use the final weeks for intensive, targeted practice and enter the exam room confident.
What if it doesn't work for me?
You're covered by our 14-day money-back guarantee. Try Premium, use all the features, and if you're not seeing progress, get a full refund. No questions asked.
