Duri reads personal files including EPUBs, PDFs, scanned documents, comics, plain text, Markdown, and saved web articles. It remembers reading position, supports highlights and notes, and can read text aloud, including recognized text in scanned PDFs. A page-turn interface, two-page spreads on iPad, reading themes, widgets, and Safari saving tools support longer reading sessions. Duri says processing for voice playback happens on the device and that personal data does not leave it; optional sync uses the user's iCloud. Books locked to stores such as Kindle or Apple Books cannot be opened. Duri Pro is a $9.99 one-time purchase in the US with family sharing, adding unlimited listening, sync, themes, fonts, and note exports. Other reading features remain free according to the listing.
