Bengali Input Engine Re-engineered for Speed & Total Privacy
An ultra-lightweight, 100% offline Bangla phonetic keyboard for Android by Infomity. Powered by on-device AI4Bharat frequency ranking, sub-15ms input response, and guaranteed zero keystroke logging.
Zero android.permission.INTERNET. The app is technically incapable of sending data off your device.
Sub-frame phonetic parsing & disambiguation running strictly in on-device memory.
Derived from openly licensed (CC0) AI4Bharat IndicCorp v2 frequency rankings.
Zero advertising SDKs, tracking pixels, or third-party analytics libraries.
Engineered for Precision & Speed
Every layer of Bangla Keyboard was built from scratch in Kotlin using native Android InputMethodService standards.
Smart Phonetic Disambiguation
N-GRAM FREQUENCY LOOKUP
Type intuitively using plain lowercase English letters. Ambiguous spellings like acho are dynamically disambiguated to আছো using precompiled statistical word frequencies, eliminating tedious candidate picking. After a word, the strip offers likely next words from a bundled word-pair list; loosely spelled input like bhallo still finds ভালো; long-pressing t, d, n or r opens the related Bangla letters; and holding Backspace deletes letter by letter, then word by word.
Air-Gapped Sandbox
MANIFEST-LEVEL ISOLATIONThe app does not request or possess network sockets. Typing keystrokes, personal communications, and passwords never leave your device.
Password Auto-Shield
CONTEXT-AWARE LAYOUTDetects password, email, and URL input fields automatically, switching instantly to English QWERTY and suppressing suggestion memory for maximum safety.
