CleverKeys — Open Source Keyboard App

CleverKeys is an open-source gesture keyboard featuring a custom neural network engine, unlimited clipboard history, and extensive customization. Unlike other open-source keyboards, gesture typing works reliably everywhere — including Termux and terminal emulators. RELIABLE GESTURE TYPING IN TERMUX CleverKeys is the only open-source keyboard with stable, production-ready gesture typing that works in Termux. Other keyboards either disable gestures in terminals, produce corrupted output, or remain in alpha/experimental state. CleverKeys works everywhere — terminal emulators, SSH sessions, and developer tools. NEURAL NETWORK SWIPE ENGINE • Custom transformer neural network trained for gesture recognition • Sub-100ms predictions with XNNPACK hardware acceleration • 100% local processing — works offline, no cloud dependency • Tunable beam search (width, length normalization, pruning, early stopping) • Open training code and datasets at github.com/tribixbite/CleverKeys-ML 208 CUSTOMIZABLE SHORT-SWIPE GESTURES • 8 directions × 26 letter keys = 208 one-touch gestures • Per-key customization — assign any action to any direction on any key • Navigation: arrow keys, home/end, page up/down • Editing: select all, undo/redo, cut/copy/paste • Function keys: F1-F12, Escape, Insert, Delete • No long-press menus needed UNLIMITED CLIPBOARD HISTORY As an Input Method Editor, CleverKeys has legitimate clipboard access that other apps lack: • Truly unlimited history (configurable by count or storage size) • Pin important items for quick access • Full-text search through history • Persistent across reboots • Export/Import for backup PRIVACY FIRST • Zero network permissions — literally cannot phone home • No analytics, telemetry, or tracking • No cloud sync or data collection • All processing on-device • Open source = fully auditable EXTENSIVE THEME ENGINE • 18+ built-in themes including Material You (Monet) • DIY theme creator with full control over colors • Key colors, label colors, border colors, swipe trail effects • ePaper, Neon, Everforest, and more styles 100+ KEYBOARD LAYOUTS • QWERTY, AZERTY, QWERTZ, Dvorak, Colemak • Programming layouts with special characters • International layouts for 30+ languages • Customizable bottom row and modifiers POWER USER FEATURES • Terminal mode with Ctrl/Meta/Fn keys • Backup & Restore all settings and custom data • Layout profile import/export with gestures included CleverKeys is a complete Kotlin rewrite of Unexpected Keyboard with neural network gesture typing, clipboard history, and per-key gesture customization added. The ML model architecture, training code, and datasets are all publicly available.
