A browser extension that reads web pages in a natural voice. The speech model runs on your own computer, not a server. Nothing it reads is ever uploaded, and there is no account, no API key, and nothing to pay for.
Every other text-to-speech extension sends the page you're reading to a server. Chickadee doesn't. It runs Kokoro, an eighty-two million parameter speech model, right here in the browser. The words you are hearing right now were made by that model, on this machine. It is open source, and it is free forever. The voice downloads once, about three hundred and ten megabytes, and then it works offline. Install it, open any article, and press Alt plus R.
Not a stripped-down reader view beside the article — the article itself, with the spoken sentence lit as it goes.

The model executes in your browser via WebGPU. There is no server to send anything to, so there is nothing to leak.
Sentences are highlighted on the page itself, not in a stripped-down reader pane. Right-click any word to start from there.
One ~310 MB voice download on first use. After that it never touches the network again — on a plane, in a tunnel, forever.
Open source, Apache-2.0 components, no subscription and no upsell. Kokoro-82M, ONNX Runtime and Transformers.js do the work.
