What You Can Do
Multi-Speaker Narration
Tag speakers with [Speaker1], [Speaker2], and [Narrator] to assign different voices to different characters. The AI handles the transitions automatically.
6 Narrator Voices
Choose from warm, deep, clear, and UK-accented voices in both male and female options. Each voice is optimized for long-form narration.
Adjustable Speed
Control narration speed from 0.8x (slow, relaxed) to 1.3x (fast). Default is 1.0x normal pace, perfect for most listeners.
Up to 10,000 Characters
Signed-in users can convert up to 10,000 characters per generation - enough for a full book chapter or long article.
Generate in Chat
You can also create audiobooks in Chat - paste your text and ask the AI to narrate it.
Instant Download
Download your audiobook audio immediately as a WAV file. No watermarks, no waiting.
How to Use
Paste your text
Paste a book chapter, story, article, or any long text. For multi-voice narration, add [Speaker1] and [Speaker2] tags before each line of dialogue.
Choose a narrator voice
Pick from 6 narrator voices - warm, deep, clear, or UK-accented. If using speaker tags, a second voice selector appears automatically for Speaker 2.
Set the speed
Choose slow (0.8x) for a relaxed pace, normal (1.0x) for standard narration, or fast (1.3x) for quick listening. Most people prefer normal or slightly fast.
Generate and download
Click Generate Audiobook. Longer texts take a bit more time. When ready, play it back in the browser or download the WAV file.
