If a picture tells a thousand words, then data visualization can present millions of words. Help your users find important concepts; to organize what otherwise may be difficult to explain. Data visualizations help users dive into your content quickly. 

Upload, edit, and modify transcriptions, and make life easier for your users. Rednal supports formatting, so you can easily mirror transcripts with their image-based counterparts.
