Lokey: Open-Source Android Keyboard Runs On-Device AI Prediction and Translation

Nicolodeva · reddit · 2026-11-10

A developer released Lokey, an MIT-licensed Android keyboard running word prediction, autocorrect, dictation and translation fully on-device via a llama.cpp fork, leveraging the Hexagon NPU on Snapdragon phones or two CPU threads. It uses LFM 2.5 350M (230MB) or Qwen 3.5 0.8B (533MB) for text and Parakeet v3/Qwen3 ASR 0.6B for speech; token logits are turned into probabilities to rank up to three word completions. No accounts, no analytics SDK, works offline after model download. Customizable with mechanical-switch key sounds, haptics and layouts. Tested on OnePlus 15 and POCO F3; signed APK and 83-second demo available.
