All single A1 and A2 level courses 25% off! Use the code START.

The Tools submenu on the main menu provides the following options:

Tools menu items


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


  • Workload (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


  • Tasklist (F4) – a tasklist manager to sort or edit the current tasklist


  • 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)
    • 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 Tools : 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
      • Optimization matrices – reset the optimization matrices used in the learning process (RF, OF, repetition cases, forgetting curves, etc.)


  • Randomize
    • Drill – randomize the final drill queue
    • Pending – randomize the pending queue

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:
    • Resume test
    • All (Alt+F11) – run a random test on all elements
    • Pending – run a random test on pending elements
    • Memorized – run a random test on memorized elements
    • Dismissed – run a random test on dismissed elements
    • Topics – run a random test on topics
    • Items – run a random test on items
    • Filter – use element filter and run a random test on a subset of filtered elements
    • Leeches – run a random test on difficult elements)
    • Subset – run a random test on a selected element subset
    • Branch – run a random test on the currently selected branch in the contents window

Random review

  • Random review (F11) – randomly review elements in the current collection


  • Options (Alt+O) – 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.
