Another option is Glasp, a web-based and PDF annotation and note-taking tool. Glasp lets you tag your highlights and notes, export to other note-taking tools and import your Kindle highlights. It offers a free plan with unlimited public highlights and export, and a Pro plan with private highlights and daily auto-sync/export to Notion. That makes it a good option for researchers and students who have a lot of reading material to annotate.
