The training ends. Then it goes quiet.
Most of what people learn fades within days — shown by memory research since 1885. Every learning platform stops at the completion click, which is exactly where forgetting begins.
Munin, the retention engine inside Origin LMS, is named for Odin's raven of memory. It begins where the course stops: short reviews, timed to the moment each skill starts to fade, and it keeps going until the knowledge has graduated.
How Munin works.
Munin has one job: notice when each skill is about to fade, and step in just before it does. Reviews are short enough to fit before a shift, between classes, or on the bus home.
-
Every skill fades on its own clock.
Munin builds a review schedule per person and per skill, using FSRS, an open scheduling model from memory research. A skill used every day needs almost no review; one used rarely comes up sooner.
-
Reviews arrive just in time.
A review is a handful of short questions, sent when a skill is starting to fade. Caught at a bad moment, it can be snoozed and Munin reschedules. Never more than two reviews are open at once, so the queue stays small enough to actually clear.
-
Graduation keeps it honest.
A skill that stays remembered stops being drilled and is only re-checked now and then. Mastered means mastered, and nobody is ground through material they already own.
A review takes under a minute.
No new lesson, no video, no separate login flow — just the questions that catch a fading skill before it's gone. It opens from the day's queue, gets answered in a few taps, and Munin reschedules the next one from there.
What managers see.
A completion report says a course was opened. Munin's team results show live memory per team and per skill, and who needs attention today, so follow-up goes where it is needed. When someone asks whether the training worked, the answer is what your team remembers, not who clicked finish.

Then follow up with one person.
Every name in team results opens into what that person actually knows: which skills are holding, which are slipping, and how long since they last practised. It's a memory record, not a login count — so the reminder that goes out is specific.
Why a raven?
In Norse myth, Odin kept two ravens: Hugin, thought, and Munin, memory. Every morning they flew out across the world, and every evening they returned to tell him what they had seen. The old verses say Odin feared for both, but feared more for the loss of Munin. Memory was the one he could not do without.
That is the job our Munin does: it flies out after the course ends, and it brings the knowledge back.
