Thai script and politeness
Thai is written in its own script without spaces between words, which the translator handles automatically. Thai also has polite particles (like ครับ / ค่ะ) and levels of formality; machine translation makes a reasonable choice, but a native speaker can fine-tune the politeness for important messages.
For everyday communication, standard Thai works well, and the translator produces the correct script for you.
Getting accurate results
Write complete, clearly punctuated sentences; they translate far better than fragments. Avoid idioms and slang, which rarely carry over.
Do a round-trip check (Thai back to English) on important passages to confirm the meaning held.
