Fluentis
Master professional English with enterprise-grade security
Learn in sequence, then stream each lesson as encrypted video that stays tied to the signed-in student.
Sequential mastery
Each level stays locked until every lesson in the previous level is complete. The server enforces the order.
Bank-grade video security
Lessons stream as encrypted HLS. The player blocks downloads and keeps a live watermark of the student email and ID.
Verified digital certification
A certificate is issued when the course is complete. Anyone can confirm it with the QR code, without seeing the student email.
