AI detection and writing verification built for schools and editors
Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.
Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.
A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.
Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.
An academic writing assistant that drafts, cites, and checks your work against real sources
Draft academic assignments and articles with an outline-first workflow, then revise, expand, or tighten sections as the argument develops.
Ask questions about a paper and get answers built from retrieved excerpts, with citations verified against the document and the source page identified.
Review tools flag attribution, citation, and source-transparency gaps, while the AI detector reports explainable signals with findings that quote your own text.
Condense long passages, restructure sentences, fix grammar, paraphrase, translate, and generate citations without leaving the workspace.
