Typing Sinhala used to be such a chore before this extension.
Offline mode actually works smoothly without lag. Huge lifesaver.
Sometimes the transliteration gets confused with mixed English sentences, but still very handy.
Clean UI, zero bloat.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
As you type in any web page, KeyMaster shows a suggestion list covering Sinhala, Tamil, and English words.
Converts Sinhala and Tamil written with Latin letters into proper Unicode script, so you can type the way you speak.
A dedicated input method editor for composing Sinhala characters directly in browser text fields.
Quick translation between English and Sinhala or Tamil without leaving the page you are working on.
Language assistance runs locally, so it keeps working without a stable internet connection and does not send keystrokes to a server.
KeyMaster solves a specific and practical problem: typing Sinhala and Tamil on a keyboard built for English. Once installed and enabled, you choose the language you want to type and start entering text in any web page. The extension shows a suggestion list and offers translations as you type, so you do not need to leave the page or open a separate dictionary or typing tool. It also includes a Sinhala Unicode IME and converters that turn Singlish (Sinhala written with Latin letters) and Tanglish (the Tamil equivalent) into proper Unicode script.
A key differentiator is that the extension is designed to work offline. Rather than sending every keystroke to a cloud service, it performs its language assistance locally, which matters for people on slow connections and for anyone uncomfortable with their typing being routed through remote servers. The developer's Chrome Web Store data disclosure states that it does not collect or use user data.
The extension is aimed mostly at Sri Lankan users and the wider Tamil and Sinhala diaspora who switch between English and their native scripts daily. It is free with no paid tier, has a small but steady user base, and is published by an individual developer rather than a large company. Because the last listed update is from mid-2022, prospective users should treat it as a stable, mature utility rather than a frequently evolving product.
Fill in forms, post comments, and write messages in Sinhala or Tamil on sites that only expect English input.
Move between English and your native script throughout the day without installing separate keyboard software.
Get quick translations and word suggestions while studying material published primarily in English.
Write in Singlish or Tanglish and let the extension convert it into correct Unicode script for posting or sending.
