Add a book

Start with UTF-8 .txt, .md, or a text-based .pdf (up to 2,000,000 extracted characters; PDFs remain limited to 10 MB and 250 pages). Long books are split into bounded source parts: you choose when to prepare each next part, and each part stays under the cost cap. PDFs with images, scans, or encryption are rejected; no OCR or image analysis is used.
