How it works
You bring the notes.
We'll find a way in.
- 01 / Bring what you have
Upload notes or a PDF, or type a topic. You don't have to tidy anything first.
- 02 / Pull out what matters
The ideas worth knowing get picked out and explained in short pieces.
- 03 / Give it a go
Each one becomes a flashcard, a question, or a quick round. See what stuck.
For the days when starting feels like a lot
START SMALL.
THAT COUNTS.
You can just do
one question.
Pick what you want to study. We'll handle the setup. You can come back for more when you're ready.

A few good
questions.
Do I need notes to get started?
No. Type a topic and Zero-in will put together explanations and practice. If you have notes, you can upload a PDF or text file instead.
Can I try it without an account?
Yes. Choose Continue as guest on the sign-in page. Guest study sets stay in your browser. An account lets you save them across devices.
What can I do with my study set?
Read the explanations, flip through flashcards, answer questions, or try a practice game. You can switch whenever you like.
Is it free?
Yes. Zero-in is free while it's in beta, with 100 AI generations a month and 10 saved study sets. With your own AI key there's no monthly cap.
Can I use my own AI key?
Yes. Open AI settings in your workspace to choose a provider and add your key. It will override the shared key.
