Load a paper, click each block to write its explanation, and export everything as one portable .dvx file. Your paper never leaves this browser.
Upload a .docx. The paper is split into clickable blocks: paragraphs, headings, tables, and images. Equations and unusual layouts may need a manual touch-up; the block editor covers that.
Upload a .md file. Headings level 1 and 2 become sections; the rest becomes paragraph blocks. Images and tables are not imported from markdown in this release.
Open a .dvx you exported earlier (finished or not) and keep working on it. Also the way to revise a finished object.
