Why am I getting errors?
Try changing your API key. Sometimes the key may expire or hit limits.
Why is my PDF not generating questions?
Make sure your PDF has selectable text. Scanned PDFs or images will not work.
Why is AI giving more or fewer MCQs?
This is a limitation of AI models. They may not always follow exact counts.
Why is generation slow?
Free models can be slower due to shared usage and limits.
Can I save my questions?
Yes! Use the save feature and access them anytime from the saved section.
Why is AI not giving correct Q&A sometimes?
Sometimes the AI reads extra text like book titles, publisher names, or headers from PDFs
and creates questions from them. Try cleaning the text or removing unnecessary parts before
generating.
Why are some questions repeated?
This happens because large text is processed in chunks. Sometimes similar content appears in
multiple chunks, leading to repeated questions.
How do I remove a selected PDF?
Open the file selector again and press cancel, or use the back button without selecting a
file. This will clear the current PDF.
Why is AI missing important topics?
AI focuses on patterns in the text. If a topic is small or not clearly explained, it may get
skipped during question generation.
Why are some questions too easy or too hard?
Even with difficulty settings, AI may not perfectly balance questions. It depends on how
complex the input text is.
Why is nothing happening after clicking generate?
Check your internet connection and API key. Also make sure you have entered text or uploaded
a valid PDF.
Why does the app lag or freeze?
Large PDFs or too many questions can slow down your device. Try reducing the question count
or using smaller inputs.
Why are answers sometimes incorrect?
AI is not always 100% accurate. It generates answers based on patterns, so occasional
mistakes can happen.
Why is my text not being detected?
If you're using a PDF, make sure it's not scanned. Only selectable text works properly.
Can I use this offline?
No, AI generation requires an internet connection to work. But you can access saved
questions offline once they are generated.
