What is Aquan 5E Letter Substitution Translator Online?

This is a text converter for tabletop roleplayers and fantasy writers who want a quick, stylized "Aquan" rendering of English text. It applies a fixed, case-sensitive substitution map: certain vowels and the digraphs Sh, Ch and Th are replaced with multi-character Aquan sequences, and the same map runs in reverse to bring Aquan text back to English. It is a letter-substitution tool, not a real language translator, and it does not claim grammar, vocabulary or pronunciation rules.

Key Features

Two-way conversion. Send Common text and get Aquan, or send Aquan text and get Common back.
Case-sensitive mapping. Uppercase and lowercase letters are handled separately, so capitalization survives the conversion.
Digraph awareness. Sh, Ch and Th are matched before single letters, so they convert as units rather than letter by letter.
Exact preservation. Spaces, punctuation, digits and any character outside the map are kept as typed, and the agent tells you which characters were left unchanged.
Transparent table. The full substitution list is available on request, so you can verify any result yourself.

How to Use

Type or paste your text and say which direction you want, for example "to Aquan" or "to English." If you do not say, the agent infers the direction from the characters present and states its assumption.
Read the converted text in the copyable block. The agent also lists any characters it could not map.
Ask for a reverse check, a different chunk of text, or the full mapping table if you want to confirm a specific letter.

Example Use Cases

Roleplay handouts. Convert a short in-game inscription into Aquan letter substitution so players see a water-themed script on the table.
Fantasy naming. Turn a character or place name into an Aquan-style spelling for a campaign wiki, then convert it back to confirm the original.
Puzzle design. Build a simple substitution puzzle where players decode an Aquan letter-substitution message back into Common, with the agent confirming the intended English.

Tips for Best Results

State the direction explicitly when your text is short or ambiguous, since a single word can sometimes be read either way.
Keep the original text handy. The reverse direction has one genuine ambiguity: both Sh and Ch produce the same Aquan output, so a reverse conversion of that sequence cannot tell you which one was intended.
Ask for the mapping table if you need to check a specific letter before publishing a handout.

FAQ

What input does it accept?
Plain text of any length. Very long passages are returned in labelled chunks so nothing is cut off. Punctuation, digits and symbols outside the map are preserved.

How accurate is the result?
The conversion is deterministic: the same input always produces the same output under the published map. Accuracy means fidelity to that map, not linguistic correctness, because Aquan here is a stylized substitution script rather than a documented language.

How does this compare with some free text tools?
Some free text tools apply a similar substitution but do not publish the table, do not state how unmapped characters are handled, and do not flag the reverse-direction ambiguity. This agent shows the mapping, preserves unmapped characters, and reports that ambiguity instead of guessing.

Does it produce audio or a font?
No. The output is plain text you can copy. There is no speech, no font file and no image rendering.
