Matter Premium will cost $8/month or $60/year and will include features that go beyond the basics: HD text-to-speech, fluid highlighting and note-taking, integrations, full-text search, options to personalize Matter, and priority support.https://hq.getmatter.com/patron
This is good to see as I’d like to see it stick around and not default to ads everywhere. However, it’s probably time to audit my subscriptions again as these things start to really add up over time.
Give Matter a try before the premium kicks in to see if it solves a need for you. I do particularly like the HD text-to-speech feature.
