CleverKeys 🗺️ Project Overview CleverKeys is the only fully open-source neural network gesture keyboard for Android. Featuring an AI-powered swipe engine that runs entirely on-device, unlimited clipboard history, and a powerful theme engine with DIY customization. No proprietary libraries. No cloud dependencies. No data collection.

Primary + secondary language support with automatic best-match selection. Why CleverKeys? CleverKeys uses a custom **transformer neural network** (encoder-decoder architecture) trained specifically for swipe typing. Unlike algorithmic approaches, neural models learn complex patterns from real swipe data. The model architecture, training code, and datasets are all publicly available at CleverKeys-ML — making it fully reproducible and auditable. **Key differentiators:** • **Only keyboard with public ML training pipeline** — verify exactly how the model was trained • **ONNX format** — cross-platform, hardware-accelerated inference via XNNPACK • **Sub-200ms predictions** — optimized for mobile with beam search decoding • **208 customizable short-swipe gestures** — 8 directions × 26 letter keys Unlimited Clipboard History Android restricts clipboard access for security - apps can't read clipboard contents in the background. But keyboards are special. As an Input Method Editor (IME), CleverKeys has legitimate clipboard access, making it the only way to get truly unlimited clipboard history without root. 📱 Reliable Swipe Typing in Termux CleverKeys is the **only open-source keyboard with reliable swipe/gesture typing in Termux**. Other keyboards either disable gestures in terminals (FlorisBoard), produce corrupted output (HeliBoard), or simply don't work (FUTO). Commercial keyboards like Gboard and SwiftKey also disable swipe in Termux. CleverKeys works everywhere — including terminal emulators, SSH sessions, and developer tools. 📲 Install Options *Recommended — Obtainium pulls directly from GitHub releases, avoiding F-Droid's typical 24-48 hour update delay. 🎨 Extensive Theme Engine CleverKeys features one of the most powerful keyboard theme engines available: Built-in Themes (18+) • **CleverKeys Dark** — Deep purple with silver accents (default) • **CleverKeys Light** — Silver keys with purple accents • **Neon Cyan/Magenta** — Vibrant cyberpunk aesthetic • **ePaper / ePaper Black** — High contrast e-ink styles • **Jungle** — Tropical teal theme • **Everforest Light** — Soft green nature theme • **Monet (Auto)** — Material You dynamic colors • **Dark / Light / Black / Alt Black** — Classic options • And many more... DIY Theme Creator Build your own themes on-the-fly with full control over: • **Key Colors** — Default, Activated, Locked, Modifier, Special • **Label Colors** — Primary, Sub-label, Secondary labels • **Border Colors** — Full border customization • **Trail Effects** — Swipe trail color and style ✨ Features 🧠 Neural Network Gesture Recognition • **Transformer-based encoder-decoder model** (5.4MB encoder + 7.4MB decoder) • **Sub-200ms predictions** with hardware acceleration (XNNPACK) • **100% local processing** — works in airplane mode • **Full inference control** — beam width, length normalization, pruning, early stopping 📋 Unlimited Clipboard History As an IME, CleverKeys has legitimate clipboard access that other apps don't: • **Unlimited history** (configurable by count or storage size) • **Pin impo…
