Explainpaper's complexity slider is the feature that makes it useful beyond just simplification
You highlight the section you do not understand and adjust the complexity level for the explanation. Graduate level means the explanation assumes significant domain knowledge and explains the specific technical gap rather than translating the whole paragraph into plain English. Elementary level means the explanation starts from first principles. The slider between those extremes is what makes the tool useful whether you are encountering a paper slightly outside your domain or completely outside it.
The follow-up question capability within the context of the highlighted section is what makes it conversational rather than just translational. If the explanation uses a term you also do not recognise, asking the follow-up within the same context window means the tool knows what you were originally trying to understand.
For academics reading outside their primary specialisation, the complexity calibration is the feature that prevents the frustration of an explanation that is either condescending to your actual level or that introduces new unexplained jargon in place of the original unexplained jargon.
What complexity level do you typically set it to and is it consistent across different research areas or do you adjust it by field?
