Add material
Upload a native-text PDF or provide a supported public URL. Online books use an available print view or table of contents—not an unrestricted crawler.
PRIVATE, SOURCE-GROUNDED LEARNING
Your sources,
taught clearly.
Turn a native-text PDF, a public web page, or a supported online book into a structured private course—with cited slides, detailed lessons, practice, and a tutor that stays in context.
Your source remains the evidence. Generated claims must point back to it.
HOW IT WORKS
From source to course in three steps.
Set your goal
Choose your level, language, and learning outcome. SY Class determines an appropriate course structure from the source.
Learn actively
Move between slides, detailed explanations, quizzes, Pencil work, and a tutor that knows the current lesson and recent conversation.
INSIDE EVERY COURSE
One workspace, not five disconnected tools.
Presentation, deep reading, practice, evidence, and tutoring share the same course context.
Presentation-ready slides
Navigate a source-specific outline, present in 16:9, or open presenter notes without leaving the course.
Grounded tutor
Ask follow-ups such as “Why?” or “Explain that more simply.” The tutor receives the active lesson, full course, source, and recent turns.
Practice with Pencil
Work through a problem on canvas and submit the image for structured feedback. The original drawing is not stored in the database.
SUPPORTED SOURCES
Bring the material you already trust.
Authenticated sources, OCR-only scans, cross-origin chapter crawling, and access-control bypasses are not supported.
