The reading loop
Search & ingest
Search all of PubMed. Open-access papers open as a structured, sectioned reader; PDFs and HTML you upload get parsed into the same shape.
Define any word
Click any term to get a plain-language definition, in context, rendered as an inline footnote — the way you'd mark up a printed paper.
Highlight & annotate
Select text to highlight and leave margin notes. Everything persists to your account and reloads exactly where you left it.
Ask the paper
A chatbot answers questions using the full paper, then scrolls to and highlights the exact paragraph its answer came from.
Build a vocab bank
Every word you look up is saved to a personal vocabulary list you can review across every paper you've read.
Journal-club worksheet
Work through a guided worksheet — question, hypothesis, methods, results, critique — and export it with your annotations as a PDF.
