In their own words
Musely Audiobook Generator
Musely Audiobook Generator turns a finished manuscript into one continuous MP3 audiobook. It accepts TXT, DOCX, EPUB, text-based PDF, or pasted text, and handles projects up to 2,000,000 characters across no more than 400 narration parts. The tool extracts text in the browser and detects chapter structure before narration upload; one narrator voice is used throughout each book. It shows the exact credit cost before rendering begins. Scanned-image PDFs are unsupported because the generator needs selectable text. Text extraction and the initial cost estimate run in the browser, with the source uploaded when rendering starts. The web-based studio is described as available 24/7, and email support covers technical, account, billing, and other questions. Musely says voice data is encrypted in transit and at rest, while voice samples are processed by third-party AI providers and stored with cloud-storage providers under contractual restrictions. The Free plan is free; the Writer plan is $4.99 a month billed annually, but includes no voice credits.
