<details> <summary><b>Footnotes & Sources</b></summary>

¹ HeliBoard requires Google's proprietary libjni_latinimegoogle.so library for gesture typing (source)

² FUTO uses "Source First License 1.1" — source-available but restricts commercial use (source)

³ FlorisBoard and AnySoftKeyboard use algorithmic approaches (corner matching, template matching) — no ML training involved

⁴ HeliBoard has a known bug where swipe typing in Termux produces duplicated/corrupted output

⁵ FlorisBoard glide typing is disabled by default and labeled "alpha quality" — must be enabled manually in advanced settings

⁶ FUTO swipe training dataset is public on HuggingFace with training code in their repo

⁷ HeliBoard clipboard retention defaults to 10 minutes but is configurable; items are not persisted across restarts by default

⁸ Short-swipe actions: 8 directions × 26 keys = 208 one-touch gestures for navigation (arrows, home/end), editing (select all, undo, cut/copy/paste), function keys (F1-F12), and more — no long-press menus needed

⁹ Multi-language swipe typing: CleverKeys uses the same neural network model for all languages — dictionaries provide word candidates, not language-specific models. 6 languages bundled (en, es, fr, pt, it, de), 5 downloadable (nl, id, ms, tl, sw). 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.
