How it works

From upload to study set in one sitting

This is a demo with sample content. Add a file, watch it become a study set, then poke at the tutor, cards and a quiz.

Seven short steps from a file to a full study set.

Onboarding that respects your time. Accounts and sign-in need backend integration.

What it does

Built around how CHS students actually study

Items marked In the demo work in the sample above. Items marked Planned are not built yet.

Messy notes in, study guide out

Drop in a PDF, slides or a photo of your notes. We sort them into short sections with links back to your pages.

In the demo

A tutor that teaches

It gives hints and points to the page in your notes, instead of just doing the work for you.

In the demo

Flashcards and quizzes

Cards come from your own notes, and you can edit any of them. Quizzes tell you what you missed and where to look.

In the demo

A study plan

Add an exam date and get a day-by-day plan you can move around.

In the demo

Offline access

The plan is for saved cards and notes to work offline. The AI tutor will still need a connection.

Planned

Built for families

Parents and guardians can look over the plans, what they cost and what each one includes.

Planned
The tutor

Hints first, answers when you want them.

The tutor starts with a small hint, shows which page it came from, and only goes further when you ask.

1

Hint

Points you in the right direction without giving the answer away.

2

Closer hint

Names the formula or the page. You take the next step.

3

Full explanation

Only when you ask, with a worked example and the source page.

Privacy
