SuperMemo 98 is a legendary piece of software that pioneered the science of spaced repetition. Decades after its release, it remains surprisingly capable for users who value raw algorithmic power over modern aesthetics. While newer versions like SuperMemo 19 offer more advanced features, SuperMemo 98 is often sought out as a lightweight, sometimes free alternative that still delivers core results. The Core Verdict
SuperMemo 98 is still effective, provided you can stomach its Windows 95-era interface and lack of mobile synchronisation. If your goal is strictly long-term retention with the minimum possible number of reviews, its underlying SM-8 algorithm is arguably more efficient than the basic SM-2 algorithm used by many modern competitors. Key Features & Performance
Despite its age, SuperMemo 98 introduced several “advanced” features that modern apps still struggle to replicate:
The Algorithm: It uses a sophisticated scheduling engine that adapts to your memory’s “forgetting curve,” significantly reducing “workload” compared to rote study.
Rich Media Support: For its time, it was revolutionary, supporting RTF (formatted text), HTML, and background images.
Complexity Levels: Users can toggle between “Beginner,” “Basic,” and “Professional” modes to manage the software’s steep learning curve.
Final Drill: A unique feature that forces you to repeat failed items at the end of a session until they are learned. Comparison: Vintage vs. Modern SuperMemo 98 Modern Anki / SM-19 Algorithm SM-8 (Advanced) SM-⁄19 or FSRS Platform Windows only Windows, Mac, Web, Mobile Cloud Sync Ease of Use Very Low (Dated UI) Price Often Freeware Paid (SM) or Free (Anki) The Challenges of Using SM98 Today
Installation Hurdles: Running a 32-bit app from 1998 on Windows 11 can require compatibility tweaks or custom launchers.
No Mobile Support: You are tethered to a desktop. Unlike modern apps, there is no way to review cards on your phone during a commute.
