SL.O Translator

Use the free SL.O translator below to turn English into SL.O, the secret language with its own alphabet and grammar, or to translate SL.O back into English. You can type Roman letters or paste the original SL.O symbols. The direction can be detected automatically.

Tips for better translations

• Use simple, complete sentences. The translator follows SL.O grammar rules, so short sentences such as “I drink water.” give the most natural SL.O.
• Check the notes under the result. Words that are not in the SL.O dictionary yet are flagged and spelled as reversible loanwords. Sentences that use grammar SL.O cannot express yet are marked as literal.
• Copy both versions. The Copy button gives you Roman SL.O and the symbol script. Roman SL.O is easier to type on any keyboard.
• Round trips are exact. Text that the translator produces translates back to exactly what you wrote, which makes SL.O safe for notes, games and stories.
