KeyMaster - Chrome Extension

KeyMaster is an offline language input assistant and translator built for Sinhala, Tamil, and English. It helps you write naturally on the web by offering smart, trilingual suggestions as you type and providing quick translations between the three languages—without relying on an internet connection.

Designed for everyday typing, KeyMaster works directly in your browser: enable the extension, choose the language you want to write in, and start typing in any text field on any webpage. As you type, it can surface relevant word suggestions and translation options to speed up writing and reduce spelling mistakes.

KeyMaster also includes specialized tools for users who type Sinhala or Tamil using roman letters. If you often type Singlish (Sinhala written with English letters) or Tanglish (Tamil written with English letters), the extension can convert what you type into proper Unicode text. This makes your writing compatible with modern apps and websites, improves readability, and ensures correct rendering across devices.

For Sinhala typing, KeyMaster provides a Sinhala Unicode IME, allowing you to input Sinhala characters efficiently even if you don’t have a dedicated keyboard layout installed. Whether you’re composing messages, writing posts, filling forms, or drafting emails, KeyMaster aims to make multilingual typing faster and more accurate—completely offline.

KeyMaster is especially useful for students, professionals, and bilingual users who switch frequently between Sinhala, Tamil, and English and want dependable typing assistance and conversions directly inside Chrome.
