AI academic search engine for peer-reviewed science
Ask a research question in plain language and get answers synthesized from peer-reviewed studies, with each claim linked to its source paper.
A visual summary shows how the scientific literature leans on a yes/no question, indicating agreement, disagreement or mixed evidence.
Narrow results by study design, sample size, journal quality, publication year and more to prioritize high-quality evidence.
Aggregate findings across many studies into structured summaries that map what is known and where the gaps are.
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.
