Yulu

Yulu is an AI-powered academic writing tool for Windows. It combines two jobs that usually sit in separate apps: finding material and writing against it. You search by keyword inside the tool, keep the results next to your draft, and write with the source visible. The second feature is content rewriting, which reworks text to reduce overlap with sources. Around the writing itself there is auto-save, local storage so drafts stay on your machine, and document export for the finished piece. The listing says it is currently free on Windows.

- Search for source material by keyword without leaving the app

- Draft with material alongside the editor

- Rewrite passages where overlap is too high

- Rely on auto-save and local storage to avoid losing work

- Export the finished document for submission

Students writing papers and theses are the primary audience, since the search-plus-draft workflow matches how coursework actually gets produced. Researchers drafting manuscripts benefit from having source material and editor in one window. Anyone who regularly works from quoted or paraphrased sources and needs to rephrase carefully will find the rewriting feature relevant, though it comes with a caveat below.

Be deliberate about the rewriting feature. Using it to reduce detectable overlap with a source, rather than to genuinely re-express your own understanding, can breach academic integrity rules at most institutions, and detection tools and penalties are the institution's decision, not yours. Cite properly and check your school's policy before relying on any paraphrasing tool. Beyond that, the app is Windows only, so Mac and Linux users are out, and free status is described as current rather than permanent. Rewrite quality also varies, so read every changed sentence yourself.
