KeyMaster - Chrome Extension

Use KeyMaster during everyday writing to move smoothly between Sinhala, Tamil, and English. Start your browser session, turn on the add-on, choose a typing mode, and write in any website field as you normally do. While you compose, it proposes context-aware words and quick language swaps so you can finish messages, forms, posts, and emails faster and with fewer errors.

When you type Sinhala or Tamil with roman letters, keep writing the way you’re used to. The tool turns that input into proper Unicode text on the spot, making it ready for modern apps and consistent on every device. For Sinhala, the built-in Unicode input method helps you enter characters cleanly even without a dedicated layout.

Translation fits into the flow. Draft a sentence in one language and request an instant version in another, then keep editing without leaving the page. This works entirely without an internet connection, so you can continue working on the go, during outages, or in low-connectivity locations.

Typical workflows include replying to relatives in Sinhala, switching to English for a work email, and posting a Tamil update minutes later—all in the same browser tab. Students can prepare bilingual summaries, convert romanized notes to clean text, and paste results directly into assignments. Support teams can answer tickets from multilingual customers, check phrasing with suggestions, and stay consistent across channels. more
