We are aware that many people would like to use SuperMemo but simply cannot afford the commercial version of the
program.
It has always been our tradition to release older
commercial versions as freeware. This policy makes SuperMemo available to anyone
who has a regular access to a computer, but has also been certifiably responsible for the
promotion of the trademark and the idea of spaced repetition. A proportion of
registered users of SuperMemo (probably around 5-10%) have also started with a freeware
version in the past.
If you cannot afford SuperMemo or your computer does not
meet minimum requirements for the newest version or you simply would like to taste the
technology before spending your money, you have the following options:
- SuperMemo on paper:
If you do not have a
computer or if you do not like to spend your time in front of the monitor, read: Using SuperMemo without a computer (1985)
- DOS version:
If your computer cannot run
Windows or is a non-DOS machine with DOS emulation (e.g. in Linux), try SuperMemo 6 for
DOS (1991). This version will experience problems when run in MS DOS Prompt window in
newer versions of Windows (e.g. Windows NT 4.0). You can download it from
here.
- Windows 3.1 version:
If your
computer runs Windows 3.1, try SuperMemo 7 for Windows
(1995). You can download it from
here.
- Windows 95, Windows 98, Windows
2000, Windows XP:
Try SuperMemo 98 for Windows
(1998). Note that some users might still prefer SuperMemo 7 (1995) for its
simplicity. You can download it from
here.
- Windows 98 through Windows 8: Try
SuperMemo 2004
for Windows (2004). For details see below
- On-line SuperMemo:
Portions of

service are free
SuperMemo 2004 for Windows

incremental reading

Freewarefiles.com
- You can also order SuperMemo 2004 along the
freeware upgrade
ticket. The registration fee will make you eligible for an upgrade to
newer versions (now or in the future). See:
Freeware Upgrade.
- Note that in newer Windows, you should install SuperMemo in a dedicated
folder, e.g. c:\supermemo as opposed to c:\Program
Files\SuperMemo otherwise Windows will disallow access to *.reg
files that have been part of SuperMemo before Windows introduced registry
files. This would require starting up SuperMemo 2004 with Run as
administrator.
