Questions, answered
Choose with confidence
What is the difference between Premium and AI Tutor?+
Premium unlocks the complete learning and problem library, written solutions, and 30 successful AI Tutor responses each month. AI Tutor includes everything in Premium with unlimited tutor responses.
What counts as an AI Tutor response?+
Only a successful answer from the tutor counts. Failed requests and provider errors do not use your monthly responses. Running, testing, or submitting code on its own does not count either.
What can the AI Tutor see?+
When you ask for help, the tutor can use the current problem, the code you choose to attach, your test results, and the conversation in that problem. This lets it give a relevant next step instead of a generic answer.
Can I still try JoinAI before subscribing?+
Yes. You can explore free lessons, coding problems, the code runner, and the community. A paid plan unlocks the full library, solutions, and AI Tutor access.
Can I change or cancel my subscription?+
Yes. You can manage your plan and billing from your JoinAI profile through the secure Stripe billing portal.
Which programming languages are supported?+
JoinAI problems support Python, NumPy, PyTorch, C++, Java, R, C, and C#. Language availability can vary by problem.
