Marginalia
A reading companion that argues back, cites its sources and remembers what you've read.
Marginalia sits beside long-form reading — papers, books, filings — and does what a good study partner does: questions the claim, finds the counter-argument, and links it to something you read last year.
Every answer points to the passage it came from. Nothing is asserted that cannot be checked.
