What is telestudy?

Telestudy is a skill for Claude Code, the AI coding assistant, that turns a book, PDF, paper, or article into a single interactive HTML study guide. The idea behind it is that most non-fiction books contain only a handful of genuinely new ideas, stretched across hundreds of pages of anecdotes and examples, and Telestudy tries to surface those core ideas without forcing you to read the whole book to find them. Each guide lets you choose how deep to go. You can skim every key idea as a single sentence and get the gist of a whole book in a couple of minutes, expand any idea to see the book's own examples and numbers behind it, dig deeper into evidence and counterarguments for the ideas you care about most, or jump straight to the original chapter, either through an Apple Books link or the source URL. The guide the author considers most useful is an interactive graph showing which ideas depend on which, so you can see how a book's argument is actually built rather than just its table of contents. Under the hood, each guide is a plain HTML file paired with a JSON block describing the book's ideas and how they connect, rendered by one shared set of CSS and JavaScript files with no build step and no external network calls, so guides keep working indefinitely. The author reports generating guides for 75 non-fiction books in one evening by running many agents in parallel, each one grounded in the actual text of its book and checked by a validator that rejects disconnected ideas, invented chapters, or quotes that run too long. To use it, you clone the repository and symlink it into your Claude Code skills folder, then invoke it in a session by pointing it at a file or a book title. The project has 6 stars, and the README does not state a license, so anyone wanting to reuse the code should check with the author first.
