What it does

A tutor that works from your course

Not another chatbot that guesses. Zemi starts from what you were actually taught.

How it works

From a pile of files to a plan

Four steps, recorded in the real app.

01

Drop in your course

Slides, PDFs, scans and photos. Zemi reads them on your computer, including the text in images, so your files stay put.

02

Ask anything about it

Answers use your notation and your syllabus, and show the page they came from. Anything from outside your files is labelled.

03

Prove you got it

A short check question follows. Zemi sees what you know and what you only recognise, and teaches to the gap.

04

Come back at the right time

Spaced review brings each idea back as you are about to lose it. Zemi remembers your progress, and you can read, edit or delete it.

How Zemi teaches

Privacy

Local first. Private by design.

Your files are read on your computer. Only your question and a few short snippets ever leave it, and you can turn cloud AI off entirely.

Files stay put

Reading, including scans and photos, happens on your computer. Nothing is uploaded to be read.

Everything that left this PC
Nothing has left your PC.

Every request is logged
