How do credits work?

What's your refund policy?
Unused credits are refundable within 14 days of purchase, no questions asked. Email [email protected].
Which languages are supported?
50+ languages including English, Spanish, French, German, Italian, Portuguese, Dutch, Polish, Japanese, Korean, and Mandarin. Voices auto-adapt to the input language.
How good is the voice quality?
We use OpenAI's neural TTS models — broadcast-grade voices used in production audio products. Try the demo above.
Which browsers does the extension support?
Chrome, Edge, Brave, Arc, and any Chromium-based browser running Manifest V3. Firefox port is on the roadmap.
How do I install the extension?
Download microtts-vX.Y.Z.zip from your dashboard, unzip it, then in Chrome go to chrome://extensions → enable Developer mode → Load unpacked → select the unzipped folder.
How do I regenerate my API key?
Open the dashboard, click Regenerate next to your key. The old key stops working immediately. Paste the new one into the extension's Options page.
Can I use it in my own app?
Yes. The API is plain HTTP: POST /api/tts with header X-API-Key and JSON body {"text":"…"}. Returns audio/mpeg.
