Vietnamese Accent Marks

Description

Vietnamese Accent Marks is a simple web tool for anyone who needs help turning plain Vietnamese text into properly accented text. It is most useful if you already have a sentence or short paragraph with missing dấu and want a faster way to make it readable again. Beginners can use it, but it is more of a text utility than a teaching site.

You paste in Vietnamese without accents, click Insert Accents, and the site generates an accented version. If a word is wrong, you can click that word and choose a different option one by one. There is also a Strip Accents mode, which does the reverse. The web interface says it supports texts up to 1000 characters, so it works best for short passages instead of long documents.

What it does well is speed and simplicity. You do not need an account, and the manual correction step is helpful when the automatic result misses a word. The downside is that it does not explain why a word takes a certain accent or tone, so it will not teach you spelling rules by itself. The author also links to a newer AI model on Hugging Face, but the website itself is still mainly a practical fixer, not a full learning resource.
