Spaced Repetition vs. Your LMS: An Honest Comparison

If you already own an LMS, "should we add spaced repetition" is not a product question — it is a question about which job is unfilled. Your LMS almost certainly does its job well. The job it was never built for is the eleven months after the course.

This page is the comparison, including the parts where the LMS wins.

Why I built this

— Sangura, founder of Quizlar. I build it solo, which means I have never once been able to buy my way out of a problem — so I got interested in the smallest thing that would fix this one.

I don’t think LMSs are bad software. I think they’re honest software being asked a question they were never designed to answer. An LMS is a system of record: it proves a thing happened on a date. That is a real job, it’s the job procurement and auditors need done, and it is done well.

The trouble is that “we trained them” and “they know it” got collapsed into one number, and only one of those is on the dashboard. Nobody decided this. It’s just that completion is easy to record and recall isn’t, and over enough years the easy number became the number.

I started Quizlar in December 2025, once agentic coding tools got good enough to build the learning tool I’d always wanted. My rule for it is simple: learning is a mental gym, so the app can rack the weights, but you still have to lift. That rule is why this page isn’t a migration pitch. Your LMS racks a lot of weights very well. It just can’t make anyone lift in March.

What an LMS does better

Everything on this list is a real reason to keep it, and Quizlar replaces none of it:

If nothing above is broken for you, nothing above is what we are proposing to change.

What no LMS does

An LMS records that a course was completed. It has no model of an individual's forgetting.

There is no field in it for "Priya is four days from forgetting the phishing escalation path." That is not an oversight — it is a different category of software. Completion is an event; retention is a curve, and tracking a curve needs a per-person, per-item schedule that keeps running long after the course closed.

So the annual course decays for eleven months while the dashboard stays 100% green — the number it reports and the number you care about have quietly stopped being the same number.

The last row is the point. These are not competing for the same slot.

How they fit together

The LMS keeps the catalog and the compliance record. Quizlar makes the content survive the week after the course.

  1. Run the course in the LMS exactly as you do now. The certificate still prints.
  2. Take the ten to thirty things an employee must still know in November — the escalation path, the retention period, the reporting threshold — and turn them into a shared org deck.
  3. Learners review hands-free, a couple of minutes at a time; FSRS schedules each person individually and resurfaces an item just before they would forget it.
  4. At review time you can show two things instead of one: that training was completed, and that the knowledge held. See Quizlar for Teams and compliance training with spaced repetition.

Nothing here requires migrating a course or retiring a system.

Where the microlearning vendors sit

Axonify, SC Training and similar tools also attack the retention gap, and if you need a full frontline-enablement suite — shift scheduling, gamified leaderboards, a content services team — they are built for that and Quizlar is not.

Quizlar is narrower on purpose: FSRS scheduling, decks built from material you already have, and voice as a first-class way to review, so training happens on a commute or a walk rather than in a seat. If retention is the only gap you have, buying a second full platform to fix it is a large purchase for a small job.

When you don't need this

Half of compliance training fails the first test and none of it fails the second. But it is worth knowing which half you are buying for.

FAQ

Does Quizlar replace our LMS?

No. The LMS keeps the course catalog, SCORM content, assignment rules and the completion record that auditors accept. Quizlar sits after the course and keeps the critical facts in memory across the year. Teams run both.

Does Quizlar support SCORM or xAPI?

No. Quizlar builds decks from source material — a policy document, an SOP, a training video — not from packaged SCORM courses. If your requirement is running existing SCORM content, that stays in the LMS.

Is a retention record acceptable as audit evidence?

It is stronger evidence than a completion log, but it is additional, not a replacement. Where a regulation specifies completion or seat time, keep producing that from your LMS; the per-learner retention record is what you bring when someone asks whether the training actually worked.

How much time does it take per employee?

A few minutes a week, spread out, rather than one long session a year. FSRS only resurfaces an item when a learner is close to forgetting it, so total time per fact falls as the material sticks.

Can it integrate with our LMS or HRIS?

Not today. Members join by email invitation or through SSO, which is how most teams onboard.

Do you support SAML?

OIDC works today — connect your identity provider and people sign in with their existing work accounts. SAML we'd build for a pilot, not something you can switch on yourself this afternoon. If SAML is a hard procurement requirement, say so early and it becomes part of the pilot scope.
