The problem, as people describe it

Laptop students annotating lecture-slide PDFs have no tool that shows the slide on the left and a synced text box on the right: Notion cannot attach text beside a PDF page, OneNote printouts come out blurry, iPad apps assume handwriting plus a subscription, and the Preview margin trick must be redone for every single lecture. Daily note-taking time is lost to tool assembly. The workflow is universal yet unserved on plain laptops.
