## What is OBooks?

OBook – Innovative AI E-Reading Experience.

Meet the first mobile reader that answers your questions about the book while you read it.  Import any EPUB or TXT title, tap the Ask OBook button, and OBook’s on-device engine scans the current context to give clear, cite-ready answers in seconds.

Why readers love OBook
	•	Conversational insight – quiz the text on themes, characters, facts, or translations without leaving the page.
	•	Drive-safe listening – start Text-to-Speech and flip into Driving Mode; giant controls keep you focused on the road.
	•	True Dark Mode – instant, flicker-free switching that’s gentle on midnight eyes (and OLED batteries).
	•	Highlight & Comment – mark sentences, add notes, and review them in one tap—perfect for study groups or editors.
	•	Fluid UI – every tap springs, fades, or glides at high fps; in full-screen the toolbar collapses to a draggable floating bar.
	•	Sleep Timer – drift off to chapter-end without draining your phone.
	•	Universal import – add books from local storage or cloud drives in EPUB or plain-text format.

Whether you’re cramming for class, road-tripping with an audiobook, or diving deep into your favorite saga, OBook blends premium ergonomics with the power of AI to make every read richer—and every tap feel just right.
