Marginalia
Read closely, write in the margins. Import a PDF or EPUB and keep free-form notes on the style of the writing — page by page, side by side.

☁︎ Sync across your computers
Connect a folder inside your iCloud Drive or Google Drive. Marginalia keeps your PDFs and notes there as ordinary files, and your cloud service syncs them to every computer — including changes made offline, which upload when you're back online.
Everything stays in your own storage — nothing is uploaded to any third-party server. Notes also autosave in this browser and can be exported as Markdown or JSON.
