audinox

Audinox turns any text into natural-sounding speech, using your own AI API key.

Paste an article, an email, a chapter, or any document — Audinox splits it into natural segments and
reads it aloud with a voice that sounds human. No accounts, no subscriptions, no tracking.

How it works
1. Add your OpenAI-compatible text-to-speech API key and base URL. TokenHub is recommended and preset.
2. Choose a model and voice, or let Audinox auto-match your language.
3. Paste or type any text. Tap play. Audinox handles the rest.

Built for listening
• Smart text splitting — long text is split by paragraph and then by sentence, so every request fits
your API's limits.
• Continuous playback — segments are synthesized and played one after another. The next ones prepare
while you listen, so there's no waiting.
• Background and lock-screen control — keep listening with the screen off. Play, pause, and skip from
the notification or lock screen.
• Adjustable speed — speed up or slow down playback from 0.5x to 2.0x in real time, without
re-synthesizing.
• Segment highlighting — follow along as the current segment is highlighted. Tap any segment to jump
or replay it.
• Offline audio cache — identical text reuses synthesized audio, saving your API quota.
• Multiple languages — built-in voice catalog for Mandarin, Cantonese, English, Japanese, and Korean,
plus the freedom to use any voice ID.

Bring your own API
Connect to TokenHub, OpenAI, or any OpenAI-compatible /v1/audio/speech endpoint. You control the
provider, the voice, and the cost. Without a key, you can try the free channel for up to 600
characters per day.

Your privacy is respected
We don't collect your text or your API key. Everything stays on your device. The API key is saved
locally and is never uploaded.

Perfect for
• Listening to articles and newsletters on the go
• Turning long documents into audio
• Proofreading your own writing by ear
• Resting your eyes while keeping up with reading
• Learning pronunciation in another language

Dark mode by default. Simple, focused interface designed for long listening sessions.

Audinox stays out of your way. Paste text, tap play, listen.
