Nubint: AI Academic Writing Checker

Check if your references really exist, spot AI-sounding passages, and see how sound your sources are — beside your draft.

Nubint is a review tool for people writing academic papers. It checks your manuscript right where you are reading it, in a side panel. ■ Reference existence We check each cited work against a scholarly index to see whether it is a paper that actually exists. Drafts written with ChatGPT or Claude mix in references that read well but cannot be found. Catch those before you submit. ■ AI writing detection We point out passages that read as AI-written, paragraph by paragraph, so you know where to edit without rereading the whole draft. ■ Source quality We check whether you are citing retracted papers, preprints, or sources whose journal cannot be confirmed. ───────────────────────────── ■ Works on Overleaf On an Overleaf project we fetch the project and read .tex together with .bib. The editor only renders the lines on screen, so scraping the page loses whole stretches of a long manuscript — we do not do that. ■ Where it works Web pages, PDFs, and Overleaf. You can also review just a selection. ■ Languages The extension follows your browser language: English, Korean, Japanese and Chinese. ■ About permissions We do not ask for access to every site at install. The moment you press "Import this page", we request access to that one site. ■ Account One connection is enough. Review runs on the Plus plan and above.
