Add Diacritics to Text

The Add Diacritics to Text Tool enhances plain text by inserting diacritical marks like é, ñ, ç, and more. It offers three modes: replacing common English words with their correct accented versions, randomly adding diacritics to letters, or applying a custom mapping of plain letters to accented ones. You can preserve original casing, highlight modified characters, and ignore numbers or punctuation.

Useful Tools & Suggestions:
