What is Readr
Readr is a free, open source ebook reader for iPhone, iPad, and Mac that lets you ask questions about the book you're reading. Select a line and ask; answers appear in the margin, grounded in the book's content, and indicate when they draw on outside science or context. You can also request spoiler-free recaps and use a natural read-aloud voice with no cap. Readr opens the EPUB and PDF files you own, requires no account, and runs entirely on your device with no server.
Key Features

Why do startups need this tool?
Readr is a good example of a lightweight, open source product that adds AI assistance directly into an everyday reading workflow while keeping everything on-device and private, with no accounts or subscriptions required.
