What is Yomu AI?
Yomu AI is a writing assistant aimed at students and researchers who write essays, research papers, literature reviews and theses. It works inside a document editor: you can have a document assistant draft whole sections, use autocomplete to continue sentences and paragraphs, and run editing commands such as paraphrase, expand, shorten, summarize, or turn bullet points into full text.
Beyond drafting, Yomu finds and formats citations in 700+ styles through a citation tool powered by Sourcely, saves sources to a personal library for reuse across documents, and includes a plagiarism checker with guidance on originality. A chat feature answers questions about academic writing and research, can work with uploaded PDFs and images, and can search the web. Figures and tables can be added, captioned and referenced in the text, and a grammar and text improvement checker is included.
