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.
Search publicly exposed cloud storage buckets and see what data they leak.
Query exposed buckets by name, keyword or provider and see which ones return publicly readable results.
Narrow results by file extension so you can assess whether sensitive document, database or media files are publicly reachable.
Surfaces the storage endpoints behind each match, making it easier to verify exposure and route a disclosure to the right owner.
Built for security research workflows — quickly triage public exposure without touching the underlying data irresponsibly.
