By creating an account or using BrainDrill (the "Service"), you agree to these Terms of Service. If you don't agree, don't use the Service.
BrainDrill is a study app for students: practice questions, an AI Tutor chat, notes, a calendar, document storage, study rooms, and a leaderboard. The AI Tutor is powered by Anthropic's Claude models and is designed to verify quantitative answers (e.g. circuit analysis, physics, multi-step math) by re-deriving them a second, independent way before presenting a final answer.
You authenticate through our identity provider (Clerk). You're responsible for keeping your credentials secure and for activity that happens under your account.
The AI Tutor uses a large language model. Even with our verification process, it can still be wrong, especially on problems it misreads (e.g. a circuit diagram) or that fall outside its training. Treat its answers as a study aid, not as a substitute for your instructor, textbook, or your own judgment — especially on graded work or exams.
Don't use the Service to violate your institution's academic integrity policies, to abuse, overload, or attempt to circumvent rate limits or security controls, or to upload content you don't have the right to share.
AI Tutor usage is metered on a rolling per-account budget to keep the Service sustainable. We may adjust these limits, and we'll reflect current usage in the product when we do.
You keep ownership of what you create or upload (notes, documents, chat messages, images). You grant us the rights needed to store, process, and display that content back to you in order to operate the Service, including sending it to the AI providers described in our Privacy Policy when needed to generate a response.
BrainDrill is currently free to use, subject to the usage limits above. We've published the paid plans we're building toward at /pricing for transparency, but no payment is being collected yet — those plans aren't purchasable until we launch billing. If we introduce paid plans, we'll give you notice before any change that affects you.
You can permanently delete your account at any time from Settings. Doing so immediately and permanently deletes your profile, notes, calendar, quiz history, documents, study room data, and AI Tutor threads — including any uploaded attachments. We may also suspend or terminate accounts that violate these terms.
The Service is provided "as is", without warranties of any kind. To the maximum extent permitted by law, BrainDrill is not liable for indirect, incidental, or consequential damages arising from your use of the Service, including reliance on AI-generated content.
We may update these terms as the Service evolves. We'll update the date above when we do; continued use after a change means you accept the update.
