When I was thinking about an ideal sponsor for the first season of the new Wonder Tools Book Group, to ensure it could be free for paid subscribers, Shortform was the clear fit.

I've relied on it for years to get in-depth guides to the long list of nonfiction books I'm curious about but haven't had time to read yet.

It's also been great for remembering key points from books I read long ago… especially as I notice my memory fading more often than it used to… and for learning about connections between whatever book I’m reading and others on related topics.

You can try it free if you sometimes forget books you read a while ago, or if you like getting a sense of books with a human-written guide. shortform.com/wondertoo… (for $50 Off).
