Four summary depths
Short · base · long · simple. Same extraction, different depth, so you decide how far to read before you start.
Chat bound to the text
Answers quote the paper's own sentences. Nothing outside the paper gets said.
Key sentences · highlights · notes
Key sentences colored by problem, method, claim, and limitation; your own highlights and notes; figure explanations.
Korean paragraph translation
A paragraph-level translation sits beside the original. Equations render typeset, not as source.
