The Toolkit submenu on the main menu provides the following options (assuming File : Level : Professional checked):

Toolkit menu items


  • Commander (Ctrl+Enter) - choose a SuperMemo command to execute


  • Calendar (Ctrl+W) - the daily and the monthly calendar of repetitions.

Sleep Chart

  • Sleep Chart (F12) - record of repetition and/or sleep blocks that will help you see your timing pattern in learning and sleeping


  • Plan (Ctrl+P) - a schedule manager that will help you plan your time by adjusting proportions of time you spend on individual activities


  • Mercy (Shift+Alt+M) - a dialog box that makes it possible to reschedule repetitions (e.g. before or after a holiday break). Use Mercy only if you want to redistribute the outstanding material in a selected period of time. If you cannot cope with material overload, you should rather use Postpone



  • Statistics
    • Statistics - a window with the main statistics of the learning process
    • Element data - a window with the statistics related to the current element. This window also displays the repetition statistics after a repetition
    • Analysis (Shift+Alt+A) - a dialog box with various statistics related to the learning process and the SuperMemo Algorithm
    • Simulation - a dialog box that makes it possible to simulate the course of learning over many years using real data collected during repetitions (see: Theoretical aspects of SuperMemo). Please note that for a low value of the forgetting index, the simulation procedure may be inaccurate (see: FAQ). The simulation uses the OF matrix used by Algorithm SM-15 (i.e. it is not based on Algorithm SM-17)
    • Report - generate a text file with statistics displayed in the Statistics window
    • Reset parameters
      • Forgetting index record - reset the record of repetition grades used in computing the measured forgetting index
      • Forgetting index vs priority record - reset the record of the forgetting index measured for different priority categories (as visible in Toolkit : Statistics : Analysis : Graphs : Forgetting Index vs. Priority)
      • First grade vs A-Factor record - reset the record of the correlation between between first grades and A-Factors
      • Average response time - reset the record of the average time it takes to respond to questions in your collection
      • Repetition history - delete the history of repetitions without affecting the learning process
      • Optimization matrices - reset the optimization matrices used in the learning process (RF, OF, repetition cases, forgetting curves, etc.)


  • Memory
    • 4D Graphs (F7) - visual presentation of memory functions, their approximations as used by SuperMemo Algorithm, and options for resetting and re-computing memory data on the basis of repetition histories
    • Memory status (F2) - show changes to memory status over time
    • Export data - export memory data for all items
    • Re-compute difficulties - update item difficulties in element data for more accurate display and browsing

Neural analysis

  • Neural analysis - build a neural queue and show how activation spreads in the network


Random test

  • Random test - run random repetitions on various subsets of the current collection (random repetitions do not count in the learning process). The following tests can be found on the Random test submenu:

Random review


  • Options - open a tabbed dialog box with options such as default interface font, default forgetting index, path to files on the CD-ROM, translation language, etc.
