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.
Trust and Safety co-pilot for online dating platforms
Models that identify specific dating-app risk vectors such as phishing, sexual assault indicators and other abuse patterns in context, rather than matching a fixed keyword list.
Incidents are automatically sorted by assigned risk level so analysts can focus on the most urgent cases and respond to affected users sooner.
Central storage for all investigation-relevant data, cutting the dependency on other teams when a moderator needs evidence to make a decision.
Facial and image blurring plus redaction of personally identifiable information keep user identities protected during reviews.
