Ubbi Dubbi is a spoken language game where players insert ub before vowel sounds. Because this tool reads letters rather than sounds, it inserts ub before written vowel groups. That makes it a simple text transformation, not a pronunciation guide.

When a word has consecutive vowels like ie in friend, the tool treats them as one vowel group and inserts ub once before the group. Separate vowels, such as e and o in hello, each get their own ub. Capitalization and punctuation stay unchanged.

| Input | Rule | Result |
|---|---|---|
| ae | one vowel group | ubae |
| a e | two vowel groups | uba ube |
| beat | vowel group ea | bubeat |
The tool scans the input text and inserts ub before every maximal run of written vowels a, e, i, o, u. Consonants, spaces, and punctuation do not receive ub. This spelling-based method may produce different results from spoken Ubbi Dubbi, which follows sounds rather than letters.
Inserted ub is always lowercase. Original letters keep their case, and spaces or punctuation remain where they are. This means capitalization inside a word or at the start is preserved for the original text, while the added ub does not change its case.
| Input | Rule | Result |
|---|---|---|
| Cat | vowel a, original C uppercase | Cubat |
| A | uppercase vowel A | ubA |
| Go! | punctuation stays | Gubo! |
Write a short message for a friend who enjoys language games. Type a sentence, let the tool insert ub before each written vowel group, then copy the result. The output is easy to reverse by removing ub, so it works as a playful note rather than secure encryption.

Use the tool in a classroom language activity. Students can enter words or short sentences and compare the output with the spelling rule. Because the tool runs locally in the browser, no account or network request is needed, so the activity can continue even without an internet connection.

Test how the rule handles different spelling patterns. Enter words with single vowels, consecutive vowels, or separated vowels to see where ub appears. This helps clarify that the tool is spelling-based and does not analyze actual pronunciation, which matters for languages with irregular spelling.

Create a lighthearted title or username. Type a short phrase, apply the translation, and copy the result. Keep in mind that the output can become long because ub is added before every vowel group. Short inputs often produce more readable results than long sentences.
