Fictional Language Translator Online

Convert English text into the fixed fictional-language token set, or decode those tokens back into readable letters. Uppercase letters share the lowercase tokens, and every unmapped character is preserved and reported rather than silently dropped. Try it online.

What is Fictional Language Translator Online?

Fictional Language Translator Online converts ordinary English letters into a fixed set of invented multi-character tokens, and converts those tokens back into letters. It reproduces a specific character-substitution scheme used by a Roblox and forum community: each letter a–z becomes a four-character token such as aowi for a or tiwo for t, the exclamation mark becomes 92la, and the question mark becomes 2lao. Uppercase letters use exactly the same tokens as their lowercase forms.

This is substitution, not translation. No words are looked up, no grammar is applied, and no meaning is changed. The tool is for writing and reading text in this invented script, checking a token string, or producing a consistent encoded message.

Key Features

Exact fixed token table. All 26 letters plus ! and ? map to their published tokens, with uppercase letters sharing the lowercase token.
Both directions. Ask for encode (English to tokens) or decode (tokens to letters); the agent states which direction it used.
Preservation reporting. Spaces, digits, punctuation and non-Latin characters are kept as-is and listed so you know exactly what was not converted.
Deterministic decoding. Tokens are matched longest-first, so overlapping strings resolve consistently instead of by guesswork.
Copyable output blocks. Converted text arrives in a clean block you can copy directly, with a short note on what changed.

How to Use

Type your text and say the direction, for example “encode: meet me at 5” or “decode: mmeaei29ei29tiwo”. If you do not state a direction, the agent infers it from the content and tells you which it chose.
Read the converted text in the code block. A short line below lists any characters that were preserved without conversion.
Ask for a reverse pass to confirm round-trip accuracy, or request a random example sentence to see the token pattern in action.

Example Use Cases

Writing a Roblox forum post in the invented script. Encode a short message and keep the exact token spelling consistent across several lines.
Decoding a fictional language character substitution message. Paste a token string you received and get the plain letters back, with any stray characters flagged.
Checking a token table by hand. Ask for the full a–z mapping with tokens so you can verify a string character by character.

Before: hi!
After: h29ai2op92la

Tips for Best Results

State the direction explicitly when your text could be read either way; short token strings can look like ordinary letters.
Keep the original text nearby when decoding, so you can confirm that spaces and punctuation survived unchanged.
Remember that uppercase and lowercase produce identical tokens, so case is not recoverable after encoding.

FAQ

What input does it accept?
Any plain text. Letters a–z and A–Z, plus ! and ?, are converted. Spaces, digits, other punctuation, emoji and non-Latin scripts are preserved unchanged and reported.

How accurate is the result?
The mapping is fixed and deterministic, so encoding and decoding are exact for supported characters. Accuracy depends on the published table, not on language understanding. Decoding is unambiguous because tokens are matched longest-first.

How is this different from some free text tools?
Some free text tools give you two boxes and leave the direction and unsupported characters unexplained. This agent states the direction, preserves and reports unmapped characters, and clearly says the output is a substitution code rather than a translation.

Can it translate a real language?
No. It only substitutes characters using this fixed token set. It does not provide vocabulary, grammar or pronunciation.
