3 due — a couple of minutes keeps your knowledge from fading.

Munin · Swedish for work, B1
Munin · memory

The course ends. Munin doesn’t.

After each module, Munin sends a two-minute review just before something is forgotten. It keeps going until every skill graduates.

How Munin works

Remembered in three simple steps

Munin works quietly after every module. Nobody has to set a reminder.

The life of a skill

Every skill moves through five simple stages. Munin takes care of each one.

  1. Learn

    Finish the lesson. Munin starts a review plan for the new skill.

  2. Keep sharp

    Short reviews come back just before the skill would slip.

  3. Wobble

    Missed one? It comes back sooner, with no fuss.

  4. Master

How it knows when

Recalling beats re-reading

Munin keeps a forgetting curve for every person on every skill, and aims each review just before it slips.

  • Built on FSRS, a modern review scheduler
  • Quiet at night, with emails capped
  • Never more than two nudges open per person
