Description

CastReader turns any text into something you can hear and understand.

LISTEN TO YOUTUBE — HEAR PUBLIC TRANSCRIPTS

Paste or share a public YouTube video link. When a public transcript is available, CastReader reads the caption text aloud with its own voices, synchronized highlighting, and automatic scrolling. CastReader does not play, download, save, or convert the original video or audio. Availability depends on the video’s public captions and your region.

READ ALOUD — STAY FOCUSED

Turn photos, web pages, PDFs, EPUBs, documents, and books into natural speech. Synchronized highlighting and automatic scrolling keep your eyes and ears on the same sentence while you study, commute, exercise, or rest your eyes.

AI EXPLAIN — GO BEYOND THE WORDS

CastReader creates and reads a clear explanation while handwritten-style annotations appear on the original: highlights for key points, circles around important terms, and numbered steps.
