Demo: the same short passage, a heading, a sentence with a citation, and a math expression, written in LaTeX, Typst, and Markdown, all rendering to the same live preview.
Currently showing: LaTeX.
AI beside your paper
Use hosted House AI for research questions with document context. For assisted editing, configure your own provider, review proposed changes, and choose what to apply. Hosted chat requests use credits through Researium's gateway.
