10 Letters Translator Online

Convert English text with the 10 Letters conlang word map, where each listed common word becomes the token 'A' and everything else is preserved exactly. You also get a per-word change report, sample sentences, and reverse lookup so the substitution is never a black box. Try it online.

What is 10 Letters Translator Online?

10 Letters Translator Online is a conversational text tool for the hobbyist ten-letter conlang whose published rule is simple and unusual: a fixed list of common English words is replaced by the single output token "A", and everything else stays as written. You paste English text, and the agent returns the converted text plus a short report showing which words were mapped and which passed through unchanged.

This is a word-substitution tool, not a full language translator. The original page never enumerates its ten-letter alphabet, so neither does this agent. What it does do is make the substitution transparent: you can see the exact word list, check the result, and ask for a reverse lookup.

Key Features

Exact published word map. Roughly one hundred common English words — function words such as "the", "and", "of", "to", plus basic vocabulary such as "day", "man", "people", "year" — are replaced by "A". The full list is applied deterministically, so the same input always gives the same output.
Preservation guarantee. Words outside the list, punctuation, spacing, capitalization of untouched words, numbers, and symbols are kept exactly as you typed them. Nothing is silently dropped.
Change report. After the converted text, you get a compact summary of how many words were mapped and a short list of examples, so you can verify the result instead of trusting it.
Sample sentences. Ask for a random sample sentence and the agent returns an English sentence built from mapped vocabulary, plus its converted form.
Reverse lookup. Ask which English words map to "A" and get the full list, or paste converted text and ask which source words could have produced it.

How to Use

Paste or type your English text into the chat. Any length is fine, but very long passages are converted in order and the report is summarized.
Read the converted text first. It appears in a copyable code block so you can paste it elsewhere without reformatting.
Ask a follow-up if you want the change report expanded, a reverse lookup, or a sample sentence. You can also ask for the conversion of a second passage in the same conversation.

Example Use Cases

Checking a ten-letter conlang sentence. You wrote "The man will take the day off" and want to see how the published map renders it before sharing it in a conlang forum.
Teaching word classes. A teacher pastes a paragraph and uses the change report to show students which words are function words and which are content words that survive the mapping.
Testing a hobby conlang idea. You are designing your own ten-letter language and want a quick baseline of how a single-token mapping behaves on real English text.

Tips for Best Results

Paste the text exactly as you want it, including punctuation. The agent does not trim or reformat your input.
If a word you expected to change did not, ask for the full word list — it may simply not be in the published map.
Remember that every mapped word becomes the same token "A", so long passages will look repetitive by design. That is the source rule, not a bug.

FAQ

What input format does it accept?
Plain text typed or pasted into the chat. There is no file upload requirement. Very long passages are handled in order, and the change report is condensed rather than listing every word.

How accurate is the result?
The substitution is deterministic: the same input always produces the same output, and the agent verifies that no characters were lost. Accuracy here means fidelity to the published word map, not translation quality — the map collapses many words into one token, so meaning is intentionally lost.

How is this different from some free text tools?
Some free text tools apply a hidden substitution and show only the result. This agent publishes the full word list, reports exactly which words changed, preserves everything else, and offers reverse lookup. It does not claim to be a complete language translator, and it does not invent an alphabet the original page never listed.

Can I convert back from the conlang to English?
Not uniquely. Because many English words map to the same token "A", reverse conversion is ambiguous. The agent can list which English words could have produced a given token, but it cannot reconstruct a unique original sentence.
