The studios. Full applications, not toys.
Each studio is a complete workspace for one kind of work — PDFs, Word documents, spreadsheets, data, slides, photos, studying, citations, maths and code. They open real files, autosave as you go, export to the formats everyone uses, and never upload your files.
