Result

Press “Run” to see the result.

Send informal Vietnamese text ("ko dc j ạ, shop ơiiii, sp nàyyy bn z") and get standard Vietnamese ("không được gì ạ, shop ơi, sản phẩm này bao nhiêu vậy") with the list of changes and their positions. A curated dictionary of about 270 abbreviations covers chat and shopping language (ko / k / hok → không, dc / đc → được, j → gì, z / dz → vậy, ntn → như thế nào, iu → yêu, sp → sản phẩm, sđt → số điện thoại, ck → chuyển khoản…). Ambiguous short forms are only replaced in a clear context: "k" after a number stays (50 k), "bn" becomes "bao nhiêu" before tiền / tuổi or at the end of a question and "bạn" otherwise, "ck" is "chuyển khoản" next to rồi / trước / stk and "chồng" next to vk.

Letters repeated three times or more are squeezed (ơiiii → ơi), a doubled final letter only when the result is a real syllable, and the Telex leftover "dd" becomes "đ" (ddi → đi). Case is kept (KO → KHÔNG, Ko → Không). Emojis can be kept, removed or turned into labels ([cười], [đồng ý]). Add your own abbreviations with dictionary; batch up to 200 texts with texts.

Useful before search, classification, profanity filtering or order extraction. The text gets no new accents: run /v1/vn-diacritics on text typed without accents.

FAQ

Can it get ambiguous words wrong?

Short forms such as k, v, bn, ck, s or h are only replaced when the neighbouring words make the meaning clear; otherwise they are left unchanged, so the output stays safe.

Can I add my own abbreviations?

Yes: pass "dictionary": {"abbr": "replacement"} (up to 500 entries). They take priority over the built-in list.

Does it add missing accents?

No, it only expands abbreviations and fixes repeated letters. Use /v1/vn-diacritics to restore accents.
