Journal, meetings and voice notes. This room never leaves your computer, on any plan.

Questions that show their work
Drop in your lecture notes or a textbook chapter. Operations Hub writes the questions, a second reader checks every answer key, and each question points to the exact line of your notes it came from.
Biology 101, week 6
Photosynthesis takes place mainly in the chloroplasts of leaf cells. Chlorophyll absorbs mostly red and blue light. In the light-dependent reactions, water is split and oxygen is released as a by-product. The Calvin cycle then uses carbon dioxide to build sugars.
What is released when water is split in the light-dependent reactions?
- Carbon dioxide
- Oxygen
- Glucose
- Nitrogen
From your notes, week 6.
Checked by a second reader
From a pile of notes to a practice test
Add what you're studying
Notes, slides saved as text, a Word file or a PDF. Each one is filed under its class, so nothing ends up in a junk folder.
Questions are written and checked
Every question has to quote your notes word for word. Then a second AI answers it without seeing the key. If the two disagree, the question is thrown out before you ever see it.
Practice until it sticks
Quizzes bring back the ones you missed first. Get one wrong and the explanation shows you the line in your notes to reread.
Your files are yours
Operations Hub runs on your computer. Your journal, health notes and meeting recordings are only ever read by an AI model on your own machine. When you ask for a study set on a paid plan, the text goes to our service, the questions come back, and nothing is kept: not the text, not the questions.
You can export everything at any time, as ordinary files. If you stop paying, nothing is deleted or held back.
Start with your next exam.
The Free plan includes 3 checked study sets a month, plus unlimited sets made by the AI on your own computer.
