The present invention relates to a document editing system using a bidirectional digital braille conversion engine, which supports a visually impaired user to perform real-time conversion and editing between braille and text. The system comprises: a processor including an artificial intelligence inverse brailletranslation algorithm; a multi-language support braille input interface that receives a braille input from a user and converts the braille input into text data; document editing software that edits and stores the text data; a multi-output interface for providing the edited text data to the user as braille and voice outputs; and an integrated accessibility module that performs conversion between text and braille in real time according to an input of the user and supports compatibility with various digital platforms.
