How it works

Three steps. Zero flashcard typing.

You already made the notes. Memiqo does the boring part.

  1. 1

    Drop your files

    Slides, PDFs, Word docs, plain text or photos of your handwritten notes. Several files in one pack: 3 on Free, 10 on Pro.

  2. 2

    We write the questions

    Memiqo reads every page and writes exam-style questions from each one: pick one of five, or select all that apply, the way Rezidențiat and USMLE papers ask. Hundreds per pack. Every answer comes with the exact line that proves it.

  3. 3

    Practice, take exams, follow your progress

    Practice with answers as you go, take a timed exam scored like the real one, or build a test from the questions you got wrong. Mastery for each topic, a daily goal and a streak show your progress.

Modes

Six ways to play the same notes.

Same questions, different pressure. Pick what fits the night before, or the week before.

  • Practice

    Due questions first, then new ones, with the answer and why after each. The everyday mode.

  • Weak spots

    Only the topics you keep missing. Short, targeted, a bit humbling.

  • Speed

    15 seconds per question. No time to overthink.

  • Exam

    A timed paper, no answers until the end, scored in points like Rezidențiat. 200 questions in 4 hours if you want the real thing.

  • Survival

    Three lives. Miss three and it is over. How far can you get?

  • Flashcards

    A swipe deck from the key concepts in your notes, plus any card you write or make from a question.

Missed some? Retry missed replays only the ones you got wrong.

Flashcards and notes

Not in a quiz mood? Read or swipe instead.

Every pack also comes with a summary, a key concepts glossary and an outline. Same source, same language.

Swipe deck

Key concepts become a deck. Swipe right when you know it, left when you do not. The ones you swipe left come back first.

Summary, key concepts, outline

Skim the summary before class. Check the glossary when a term stops making sense. Use the outline to see what you have not covered yet.

Lecture 4: Membranes

Cells keep their insides separate from the outside with a selectively permeable membrane. Crossing it is either free (down the gradient) or paid for in ATP (against it).

What crosses freely?
Small nonpolar molecules diffuse straight through the bilayer; water and ions use channels.
When is ATP spent?
Only against a gradient: pumps, and vesicles for anything big.

Daily goal, streak, mastery

Studying, but it keeps score.

A daily goal, a streak to protect and a mastery ring for each topic. Confetti when you score 80% or more.

  • 12days

    Streak

    Each day that you study adds one day to your streak. A full day without study resets it.

  • 17of 20 today

    Daily goal

    Answer 20 questions a day to reach your goal. Flashcards that you review count as well.

  • 81%

    Mastery

    Spaced repetition tracks each topic. Weak ones come back sooner, strong ones later.

Which files can I drop in?

PDF, Word (DOCX), PowerPoint (PPTX), plain text and PNG or JPG photos of your notes. On Free you can add 3 files per pack, up to 40 pages each. Pro takes 10 files per pack, up to 400 pages each.

Does it work with material in other languages?

Yes. Memiqo writes the questions, explanations and notes in the same language as your material. No settings to change.

Is my material private?

Yes. Your files and packs are only visible to you and are never shared with other students. To write the questions, the extracted text is sent to an AI provider, and photos or scans go to an OCR provider to read the text. You can delete your account in Settings: you type DELETE to confirm, and you may be asked to sign in with Google again first.

How many questions do I get?

A lot. Memiqo writes questions from every page of your material, roughly one every few sentences, so a 40-page lecture becomes 400 or more. When you have been through them, a new layer of questions covers every page again from a different angle: 1 extra layer per pack on Free, 3 on Pro. Each new layer counts the pages of the pack again against your monthly pages.

What do I get on Free?

3 packs with 3 files each, up to 40 pages per file and 40 pages per month, plus 1 extra layer of questions per pack. Every mode, exams, flashcards and notes are included. Pro is about volume, not features.

Can I cancel anytime?

Yes. Manage or cancel Pro from Manage billing in Settings. You keep Pro until the end of the period you already paid for.

Does it work on my phone?

Yes. Memiqo is a web app that works in any modern browser and can be added to your home screen like an app. Flashcards swipe, quizzes tap.

How good are the questions?

They are written the way exam questions are: one thing asked, five parallel options, distractors that are real confusions from the same material. Every question quotes the exact line that proves the answer, explains why each option is right or wrong, and if one still looks off you can remove it with a tap.

What happens when I get a question wrong?

You see the right answer, the line it came from and why. The question lands in your incorrect pile so you can build a test from just those, the topic is marked as weaker so it shows up sooner in Practice and Weak spots, and you can replay only your misses with Retry missed.

Your notes are already written. Go get quizzed.
