Grok Text to Speech is a free, independent web playground for xAI's official text-to-speech API. xAI's built-in Grok voices are among the most natural-sounding AI voices available, but until recently the only way to hear them was inside the Grok app or behind a developer API key. This site opens them to everyone: paste any text, pick one of all 28 built-in voices - the five originals (Ara, Eve, Leo, Rex, Sal) plus 23 added since - and hear it instantly.

Every voice speaks all 20 supported languages, with auto-detection, and speech tags like [pause], [laugh] and <whisper> wrappers change how each line is delivered. Signed-out visitors get three free previews a day (200 characters each, play-only). A free account unlocks MP3 downloads (24 kHz, 128 kbps), and Google sign-in raises limits to 1,000 characters per clip, 20 clips an hour and 3,000 a day. Paid plans from $5 a month cover longer clips and higher volume.

Privacy is simple: nothing you type is stored or logged. Text goes to the API and the audio streams straight back. Built on Cloudflare Workers and xAI's public API; not affiliated with xAI.
