REden

Find the core. Follow the meaning.

REden helps you focus on the words that carry a sentence’s meaning. By bringing its essential structure into view or gently softening less important words, it is designed to support faster reading and clearer understanding—while keeping the full text in place.

Available in the preview

Emphasis shaped by words and meaning.

REden combines sentence structure with word frequency and word parts to choose which letters to bold. Important words receive stronger emphasis, while the full text stays visible.

Future direction

More languages. More ways to understand.

Our long-term goal is to bring REden to more languages.

Languages build sentences differently, so subject–verb–object will not apply the same way everywhere.
