Reading a book alone is a private act. It does not have to be. Reading Circle finds the people on Substack talking about the book in your hands, shows you what they said, and puts them all in one note.
Free. You will also get The Master Mindset on Substack, and you can leave any time.
Or open Discover and see what people are reading right now. Every title is checked against Substack before it appears, so the grid only shows books with a live conversation.
Everyone who has written about it, with the thing they actually said and a link straight to the note. Anyone you already follow is marked and moves to the top.
One button opens a Substack note with every reader tagged for real, so they all get notified. Nothing is ever posted for you: you read it and hit Post.
The book sits at the top of Discover, alongside the library it draws on. Open it and you see who else is working through the same ideas, in their own words, on their own pages.
That is the whole point of the extension. Not a list of titles. A room of people already in the middle of the same thing you are.

Drop your email and the extension downloads straight away, with the install steps on the next page.
