- Is this a subscription?
- No. Each offer is a one-time purchase. There is no monthly, annual, or recurring charge.
- What does All-Access include?
- Exactly four current courses: AI Engineering Foundations, AI Systems Engineer, AI Automation Engineer, and AI Security Engineer. Future products are not included.
- Do I need Foundations first?
- No. Foundations is optional. Choose it if you want more practice with Python, Git, testing, APIs, and engineering fundamentals before a specialist course.
- What is the AI Tutor?
- It is an in-course learning assistant that can explain concepts, help debug your reasoning or work, and guide you through a problem.
- Do I need my own API key for AI Tutor?
- Yes. Connect your own supported OpenAI or Anthropic API key. Your provider bills model usage directly to you; Quantil Labs does not include model usage in the course price.
- Can AI Tutor complete course work for me?
- No. It is designed to preserve the exercise, give bounded guidance, and help you reason through the work rather than provide finished assignments or guaranteed answers.
- How do I access a purchased course?
- Sign in with the account used at checkout. Access becomes active after the payment provider confirms the transaction.
- Is tax included in the displayed price?
- Tax is not estimated here. The payment provider calculates and displays applicable tax before payment.
- What happens to my work if access is revoked?
- Paid unit bodies become locked, but your progress, Quick Check history, and notes are not deleted.
