The forgetting curve and your review schedule

Ebbinghaus's work on forgetting highlights how memory can fade over time. Spacing reviews across different days helps you revisit what you learn. knowloop turns that idea into a simple fixed schedule; it does not predict your personal forgetting curve.

Illustration only: these curves do not predict your memory. Review intervals are not drawn to scale.

Turn your notes into AI flashcards

Turn each note into a question you can answer from memory. AI turns your notes into questions, reference answers, and source excerpts. Check the cards, then practice recalling the answers.

  • Generate 2–3 cards from 20–10,000 characters of notes
  • Edit and verify your cards, then reuse them in every due review
  • Prefer to write your own? No notes needed

Start spaced repetition in three steps

  1. 1

    Log a study topic

    Add a title, category, and study time. Generate AI flashcards from notes, write your own cards, or save notes on their own.

  2. 2

    Get a review reminder

    Reviews are scheduled after 20 minutes, then 1, 2, 4, 7, 15, and 30 days. Receive an email when a review is due.

  3. 3

    Recall and check in

    Answer each question before revealing the reference answer and source excerpt. Record whether you recalled it, were unsure, or could not recall it.

Your own notes. A simple review plan.

Track lecture notes, reading highlights, or exam topics in one place. A clear queue of due reviews saves you from repeatedly planning when to revisit each topic.

knowloop uses fixed intervals. Difficulty ratings record your recall; they do not automatically reschedule future reviews.

Frequently asked questions

Can I generate flashcards from notes with AI?

Yes. Add a title and 20–10,000 characters of notes to generate 2–3 cards with questions, reference answers, and source excerpts. Check, edit, and confirm them before saving. Saved cards are reused in later reviews. You can also write cards without notes.

What is knowloop?

knowloop is a free spaced repetition app for your own study topics. It creates seven fixed review dates, sends email reminders, and keeps your review history.

What spaced repetition schedule does it use?

Reviews are due 20 minutes, then 1, 2, 4, 7, 15, and 30 days after learning. This is a practical fixed schedule, not a prediction of the best review time for every learner.

Do I need to download an app or make flashcards?

No download is needed. Use knowloop in your phone or desktop browser. AI flashcards are optional; you can also review your notes directly.

Is knowloop free?

knowloop is currently free to use. Create an account to log topics, receive email reminders, and track completed reviews.

What if I miss a review?

Overdue reviews stay on your Today list. Complete them later or clear the overdue queue. Your completed history and other future reviews are kept.

Can other people see my topics?

Your topics and review history are private to your account. They are not published or shared with other users.
