Reading Thai just got easier.
Thai Word Splitter helps beginners and intermediate learners read Thai text more confidently — by automatically adding spaces between words and providing a full translation of every sentence.
Why Thai is uniquely challenging
Thai is written without spaces between words — a system called scriptio continua. Every sentence is a continuous stream of characters, with no visual clue about where one word ends and the next begins.
For native speakers, this is completely natural. For learners, it's one of the biggest barriers to reading fluency. Even at an intermediate level, a long unbroken line of Thai text can feel impenetrable — even when you know most of the vocabulary inside it.
Suddenly the sentence makes sense. Individual words become visible, pronounceable, and memorable.
Who it's for
Beginners
Breaking text into word-sized pieces makes it far easier to look words up, understand sentence structure, and build confidence reading real Thai. Start with simple sentences and work your way up.
Intermediate learners
Tackle news articles, social media posts, menus, and messages from Thai friends. Use the translation as a comprehension check rather than a crutch — see if you can read the split words before looking at the answer.
How it works
Paste any Thai text into the tool. Thai Word Splitter uses BudouX — an open-source machine learning model from Google — to identify word boundaries intelligently. It runs entirely in your browser, with no text sent to any server for processing.
A full sentence translation is then fetched from the MyMemory translation API, giving you the meaning of each line in context — far more accurate than translating word by word.
Chrome Extension
The Thai Word Splitter Chrome extension is now in beta. Select any Thai text on any webpage, right-click, and a floating panel appears instantly with split words and a full sentence translation — without leaving the page or copying anything.
It also works via keyboard shortcut (Alt+S on Windows, ⌘⇧S on Mac) and has a full popup tool accessible from the toolbar.
