WHAT IF YOUR IB FEEDBACK ARRIVED WHILE YOU WERE STILL WRITING?
MARGINALIA READS YOUR DRAFT AS IT DEVELOPS — TELLING YOU WHEN YOU'RE ON TRACK, AND WHEN TO CHANGE COURSE.
How it works
01
Click Check now while you write — Marginalia reads what's on your screen.
02
It floats above Google Docs, Word, or Pages. No upload, no tab switching.
03
One tip streams into the overlay. Ask a follow-up right there.
