Frequently Asked Questions

Is Flux English really free?
Yes! Our core features, including lesson viewing and basic AI feedback, are completely free. We believe education should be accessible to everyone.
How does the AI feedback work?
Our AI listens to your recording and compares it against the original video audio. It analyzes pronunciation, intonation, and timing to give you a similarity score and specific tips for improvement.
Can I use my own YouTube videos?
Currently, we curate videos to ensure they have high-quality captions suitable for learning. However, a feature to import any YouTube video via link is coming in the Premium update.
What level of English do I need?
The platform is best suited for beginners to intermediate learners (A2-B2 levels). We categorize videos by difficulty so you can find content that matches your skills.
