Questions, answered
Clear answers to how ClasSync protects privacy, syncs calendars, and stays free.
Who can see my notes and question papers?
Only approved accounts. Every signup waits for a classroom admin to approve it, and access can be revoked at any time for classroom safety.
How does the AI Quiz Generator work?
Click 'Quiz' on any note to generate an adaptive quiz with multiple-choice, assertion-reason, and conceptual questions. Students get instant scores with explanations, and teachers or authors can save and publish official class quizzes.
What is the Socratic AI Homework Helper?
Unlike tools that spoil answers, the Socratic Helper acts as an encouraging personal tutor. It guides you step-by-step through problems, asks clarifying questions, probes formulas, and scaffolds hints so you truly master concepts.
How does the Mock Question Paper Bank work?
Generate authentic school exam papers aligned with CBSE and State Board blueprints (Sections A to D with marks distribution). Practice under realistic timed countdown conditions or print and export NCERT-style watermarked PDFs.
What are Subject Flashcards and Spaced Repetition?
ClasSync automatically extracts key formulas, definitions, dates, and grammar rules from uploaded notes into 3D interactive flashcards, scheduling active recall reviews at 1, 3, 7, and 14-day intervals.
How does phone calendar deadline sync work?
Every homework and assignment due date appears in the countdown timeline. You can add any individual deadline — or export your whole schedule at once (.ics) — straight to Google Calendar, Apple Calendar, or Outlook with automated 2-hour reminders.
How does on-device photo enhancement and NCERT-style watermarking work?
It runs entirely on your device inside the browser! Remove notebook shadows, sharpen board photos without uploading duplicate heavy files, and export PDFs protected with authentic diagonal NCERT-style watermarks.
