What it does
You point book-to-skill at a PDF or a folder of documents. It turns the content into a "skill", a structured pack your AI coding assistant can load when needed, with key ideas, a chapter index, a glossary, patterns and a cheat sheet.
Later you can ask a question about the book and the assistant reads just the right chapter to answer from the real content. Its makers say this uses far less of the AI's working memory than loading the whole book each time.
It works with assistants that support the open Agent Skills format, including Claude Code, Codex, GitHub Copilot CLI and others. It also works on internal docs, brand guides, research papers and specs.
Who it's for
Developers and learners who want their AI assistant to answer from books and documents they own.
