Before you forget,
we ask.

Upload lecture PDFs, slides or Word files. AI writes questions on the key ideas, and a notification asks you one right when your memory starts to fade.

Q. A transaction runs completely, or not at all.

Correct!We'll ask this one again in three days. The gap grows each time you get it right.

How it works

You upload.
Mirimi remembers when.

Upload your material

Pick a PDF, PowerPoint or Word file, or send one with Share from chat or mail. The original file never leaves your phone — only the extracted text is saved.

Get questions

AI writes questions on the key concepts of your material, not trivia like the numbers inside an example.

Multiple-choice question

Review before you forget

Missed questions come back soon; the ones you get right come back at growing intervals. You choose the times, days and quiet hours.

Only what's due today,

Today's questions are gathered with an estimate of how long they take. Right answers make it harder and misses make it easier — format and difficulty adapt as you go.

When you miss, the explanation shows which sentence of your material the question was built on, so you can check the AI's work.
