Ubbi Dubbi translator
Hello world becomes Hubellubo wuborld: the syllable ub goes before every vowel a, e, i, o and u, while y, spaces and punctuation stay as they are. Decoding removes the added syllables and brings the message back. Free in your browser.

Ubbi Dubbi is the playful language game that inserts the syllable ub before every vowel so Hello becomes Hubellubo and cat becomes cubat. Children, teachers, puzzle authors, and anyone drafting secret-club style messages use it for light obfuscation that is easy to speak aloud and easy to reverse once you know the rule. Spaces, punctuation, digits, and the letter y pass through unchanged so phrases keep their shape. You choose the mode explicitly—encode or decode—so scripts never guess which way the string should go.
How Ubbi Dubbi encoding and decoding work
Ubbi Dubbi is not encryption and not a cipher with a secret key. It is a fixed language-game rule used in classrooms, summer camps, and kids television: before every vowel sound written with the Latin letters a, e, i, o, or u, insert the short syllable ub. On encode, this tool walks the input character by character.
When it finds a vowel, it inserts ub if the vowel is lowercase or Ub if the vowel is uppercase, then keeps the vowel itself. Consonants stay as they are. Spaces, commas, periods, digits, emoji, and the letter y never receive an inserted syllable, so Hello world becomes Hubellubo wuborld and happy stays hubappuby with y untouched.
Consecutive vowels each get their own ub, so book becomes buboubok and idea becomes ubidubeuba. On decode, the scanner looks for the two-letter sequence ub in any casing immediately followed by a vowel letter; when that pattern appears it drops the ub and keeps the vowel. If ub appears before a consonant, as in the ordinary English word hub, the letters pass through without special treatment because they are not the language-game prefix before a vowel.
There is no random seed, no network call, and no wall-clock timestamp in the path: every step is a pure string scan. This page implements that fixed Ubbi Dubbi profile only—not Pig Latin, not leetspeak, not ROT13, not Base64, and not an AI rewriter that invents creative spellings. Those are separate tools and search intents.
Where an Ubbi Dubbi translator shows up in real work
Elementary language-arts and phonics lessons often introduce language games so students practice identifying vowels; a single trusted Ubbi Dubbi oracle speeds demos and auto-graders that need both encode and decode. Puzzle books, escape-room clue chains, and kids party invitations still hide messages in Ubbi Dubbi that adults and older siblings want to reverse without writing a one-off script. Support and content teams sometimes lightly stylize spoilers, quiz answers, or club nicknames in Ubbi Dubbi form and later need a reverse path without installing a language-specific library.
If you need Pig Latin, leetspeak, a rotation cipher, strong authenticated encryption, or Base64 encoding, treat those as separate search intents and landings rather than overloading this fixed Ubbi Dubbi page.

FAQ
What is Ubbi Dubbi?
Ubbi Dubbi is a language game that inserts the syllable ub before every Latin vowel (a, e, i, o, u). For example Hello becomes Hubellubo. It is playful obfuscation, not cryptographic security.
How do I convert text to Ubbi Dubbi?
Send your string in the text field with mode encode (the default). The tool inserts ub before each vowel; consonants, spaces, punctuation, digits, and y pass through unchanged.
How do I translate Ubbi Dubbi back to plain text?
Set mode to decode. Any ub, Ub, or UB immediately before a vowel is stripped, recovering the original wording when the input was valid Ubbi Dubbi.
What does the Ubbi Dubbi translator cost?
The browser tool is free and runs locally.
What happens when two vowels are next to each other?
Each vowel gets its own ub, so book becomes buboubok and idea becomes ubidubeuba. Decoding removes every ub that sits right before a vowel, so both words come back exactly as they were.

API endpoint
Prefer to automate it? One authenticated POST creates the task; the result comes back by webhook or a signed link. The same capability also runs here on the web, by email and from Telegram — and soon from our app too.

Technical notes
This Ubbi Dubbi translator applies a fixed deterministic algorithm in either direction: encode plain text into Ubbi Dubbi by placing ub before each Latin vowel aeiou, or decode Ubbi Dubbi by stripping those syllables before vowels so the original wording comes back. Empty input is rejected with a clear invalid_input error rather than returned unchanged.
What you send and what you get back
Send a required string field named text containing the message you want to convert. Optionally send mode as encode or decode; when omitted, encode is the default. Classic checks include encoding Hello world into Hubellubo wuborld, decoding Hubellubo back to Hello, and confirming that an empty text field is rejected rather than returned unchanged. Aliases such as input, value, data, message, plaintext, and source are accepted for the same field so scripts can reuse existing payload shapes. Direction aliases such as op, operation, and direction, and short values like enc, dec, to_ubbi, and from_ubbi are also accepted. On success the response echoes the original text, returns result as the transformed string, mode as the resolved operation, length of the result, and either vowels (how many vowels received an ub on encode) or stripped (how many ub syllables were removed on decode), plus cipher and rule labels so clients can assert they hit the Ubbi Dubbi profile. Missing text, non-string objects for text, empty strings, unknown mode values, and strings longer than the documented maximum fail with invalid_input and a clear English message. Validation failures do not consume prepaid balance. Pricing for successful API calls is the published base of $0.002 per item.
Where an Ubbi Dubbi translator shows up in real work
Because this capability is a pure parse engine, API pricing is the published base of $0.002 per successful item and failed validation does not consume balance.

Technical questions
What happens with empty or malformed input?
Empty text, missing text, unknown mode values, and oversized strings fail with invalid_input. Those validation failures are not charged.
