FAQ
Will the free tier ever be restricted?
No. The complete C++ reference, all learning paths, and runnable examples are permanently free. We will never put core educational content behind a paywall.
What is 'Ask bigCpp'?
An AI-powered search that understands your question in context and surfaces relevant reference pages, code examples, and book excerpts — grounded in bigcpp.com content, not hallucinated.
How does offline access work?
Install bigcpp.com as a PWA (Add to Home Screen). Once installed, recently visited pages are cached by the service worker and available without an internet connection.
Can I cancel anytime?
Yes. Cancel from your dashboard and your Pro access runs until the end of the billing period. We offer a 14-day full refund — no questions asked.
Do you offer team or educational discounts?
Email pro@bigcpp.com for team pricing (5+ seats) or student/academic discounts.
