Troubleshooting

The most common problems and what helps.

The model download doesn't start

  • "No internet connection": Connect the computer to Wi-Fi and try again.
  • "Wi-Fi only": Windows considers the current connection mobile or metered (e.g. a phone hotspot). Lernbuddy deliberately doesn't download over it. Connect to a normal Wi-Fi network.
  • "Download failed": Usually a short interruption. Just click Download model again – the download resumes where it stopped.
  • Not enough disk space: The model needs about 4.6 GB plus some room to spare. Free up at least 6 GB.

The first answer takes very long

When the program starts, Lernbuddy loads the model into memory. Depending on the computer that takes 5 to 30 seconds. The notice bar at the top shows what's happening meanwhile. After that it's much quicker.

Answers come very slowly

Without a suitable graphics card the AI runs on the processor only. That works but is slow. What helps:

  • closing other big programs (games, lots of browser tabs),
  • updating the graphics driver so the graphics card can be used,
  • plugging the laptop in – on battery, Windows often throttles performance.

Lernbuddy crashes while loading the model

Usually there isn't enough memory. Lernbuddy needs at least 8 GB of RAM. Close other programs and restart Lernbuddy.

The quiz grades an answer wrongly

  • A correct answer isn't accepted: Open the card in the Flashcards tab and change it with ✎ – for example, make the answer shorter. If Lernbuddy suggests a variant, confirm it with Accept.
  • A typo counts as "Not quite": Probably the mistyped word is itself a real word. That's intended – see How answers are checked.
  • The card itself is wrong: Cards made by the AI can contain mistakes. Fix them with ✎ or delete them with ✕.

The setup file won't start

Windows SmartScreen blocks unknown programs. Click More info and then Run anyway. Details in Installation.

The language is wrong

Lernbuddy starts in the Windows language (German, otherwise English). You can change it at any time in the Help tab under Language; the choice is remembered.
