The situation

What was in place before we started.

Matter is a modern read-later app that saves articles, threads, PDFs, newsletters — even YouTube and podcasts, auto-transcribed into time-synced text — into one distraction-free library. A 3× Apple “App of the Day”, it is highly rated on the App Store.
