About KeyTab
KeyTab is a privacy-first keyboard (IME) for Android, 100% Kotlin and free software (MIT).
File manager in the keyboard
Browse folders in tabs, navigate with back-stack and parent-navigation. Tapping a file inserts its path or opens it via a VIEW intent. Each tab remembers its own directory. Listing runs asynchronously, so large folders never freeze the UI.
Offline word prediction
An n-gram model (FrequencyWords de_50k, CC-BY-SA-4.0) with bigrams for next-word prediction, a self-learning user dictionary, prefix autocomplete, fuzzy correction (Damerau-Levenshtein) and case matching — all on-device. Export/Import lets you optimize suggestions with a local LLM. Your data never leaves the device.
Dynamic key sizing
Likely-next keys scale up to 1.21x (second grade 1.15x), unlikely neighbours down to 0.812x, driven by the current suggestion scores. Toggleable in settings.
Notes & clipboard
An editor tab with save/load plus a persistent clipboard history (up to 50 entries) — tap an entry to insert it directly into the target field.
Keyboard features
Dedicated TAB key (great for Termux/SSH), shift/caps-lock, long-press popups for umlauts and special characters, accelerating backspace on long-press (250ms down to 30ms).
Privacy
No network permission. No analytics, no tracking, no data collection.

| Release info | Update on Nov 07, 2026 |
|---|---|
| Release notes | • Version 0.23: the green accent bar above the active tab is back — it now lives in the tab cell's background where Android keeps it green on every tab switch. • The suggestion row is flat now: the separate green bar on the top suggestion chip is gone, all five chips look equal. • Fix: the bar had been invisible before (wrong drawable layer), reported on Android 16. • No settings changed; existing keytab_config.txt files keep working unchanged. |
