Sapiens

Sapiens turns a topic into a book you actually finish.

Give it a topic, an audience and a depth. Sapiens writes the syllabus — ordered modules, each with a title and description — then a complete lesson for every module: prose, code, authored diagrams, typeset formulas, and practice built into the page (quizzes, flashcards, glossaries, common mistakes, case studies, matching, cloze).

Read it in the app or take it with you: export to PDF or EPUB, or send it straight to your Kindle and read it as a real book. Highlight a passage, leave a note, and regenerate the module — your annotations drive the rewrite. A learner profile remembers what you already know, so the second course is more yours than the first.

It works the other way round too: Sapiens exposes itself over MCP, so your own agent — Claude, or any MCP client — can author a course directly and have it land on your Kindle. Published in the official MCP registry as com.getsapiens/sapiens.
