Kokoro-82M is a remarkably small neural TTS model that sounds far better than its 82 million parameters suggest, and it runs comfortably in a browser tab. Pick a voice, paste text, and get a WAV you can download — no character quota, no per-thousand-character billing, and no upload of the script. SpeechT5 and MMS-TTS are available as alternatives, MMS in particular for languages Kokoro does not cover.

Check the model licence on Hugging Face — Kokoro-82M is Apache-2.0, which permits commercial use. We add no additional restriction of our own; the audio is generated on your machine and is yours.
That is the one-time model load and GPU warm-up. Subsequent generations are much faster because the weights are already resident.
Yes, once a model is cached. Weights are stored in the Cache Storage API under the key "transformers-cache", so a reload with no network still runs the model. Call "Make storage persistent" first — browsers may evict non-persistent caches under disk pressure.
