Is this text to speech tool really free?

Yes — it runs a real neural TTS model (Kokoro-82M) entirely in your browser. There is no account, no credit system and no server doing the work, so nothing to bill you for. Your only cost is the one-time ~86 MB model download.

Does it work offline?

After the first visit, yes. The voice model is cached by your browser, so later generations work with no internet connection. The very first generation needs a connection to download the model.

What voices are available?

Ten verified English voices: Bella, Nicole, Sarah, Sky (American female), Adam, Michael (American male), Emma, Isabella (British female), George and Lewis (British male). Only these are offered — every listed voice is confirmed working with the model.

Can I use the audio commercially, for YouTube or ads?

The model itself is Apache-2.0 licensed, which permits commercial use, but you are responsible for how you use the output — for example, platform rules for AI-generated voices on YouTube or ad networks. When in doubt, check the policy of the platform where you publish.

Why does the first generation take so long?

The first run downloads the ~86 MB model and warms up your device's AI runtime. Later runs skip the download entirely and are much faster, especially in browsers with WebGPU (Chrome/Edge 113+).
