Questions

Is the free version actually free?

Yes โ€” every cheat sheet, all the worked problems, the complexity tables and the interview playbook stay free, no account needed. Premium adds tools on top; it never locks away what's free today.

What is the AI coding tutor?

A chat assistant, running on AGenO's own hardware, that you can ask to explain a solution, suggest a faster approach, walk through the Big-O, or help debug your code. It's a study aid, not a magic answer key.

What does "soon" mean on some features?

We're upfront: PDFs, mock-interview mode and progress tracking are being built right now. A Premium subscription includes them automatically the moment they ship โ€” no upgrade, no extra charge.

Monthly vs. yearly?

Monthly is the flexible option. Yearly bills once and works out to about half the monthly price โ€” best if you're prepping over several months.

Can I cancel?

Anytime, in one click. Your access stays active until the end of the period you already paid for, then you simply drop back to the free tier.

How do payments work?

Securely through our payment provider (Lemon Squeezy), which handles cards and tax. AGenO never sees your full card details.
