Yes. During beta, everything is free — including features we'll later move behind Pro. We'll give you plenty of notice before anything changes, and existing users will be grandfathered in.
Do I need to create an account?
No. Your tutor or the kalc team gives you an access code. You type it once and you're in. No passwords to forget, no email spam.
How is this different from Khan Academy or Linus?
kalc is the only prep tool that reads your actual handwritten work. Most tools grade the final answer. We look at your solution line by line and tell you exactly where the reasoning broke.
Will you offer group/school pricing?
Yes — when Pro launches we'll have discounted pricing for tutoring groups and schools. Reach out if you're interested in early access.
