Why CleverKeys

The only open-source keyboard with a public ML pipeline.

Every layer of the stack — model, training data, tokenizer, app — is inspectable, reproducible, and yours.

Neural gesture engine

Transformer encoder-decoder with beam-search decoding, quantized ONNX + XNNPACK. Sub-200 ms on a Pixel 7.

100% on-device

Zero network permissions. No analytics, telemetry, or cloud sync. It literally cannot phone home.

Unlimited clipboard

Persistent history with pin, todo, tag filters, drag-to-reorder, media support — survives reboots without root.

208 swipe gestures

8 directions per key, per-layer. 204+ built-in commands plus custom macros, function keys, nav.

Works in Termux

Only open-source keyboard with reliable swipe typing in terminal emulators. Others crash or corrupt input.

Fully open source

App, model, training pipeline, datasets, and test harness all public. Reproduce every weight end-to-end.
