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.
Runtime data security for AI and SaaS workflows
Build context-driven policies for your organisation's unique AI usage, then group human and non-human identities to control how each can interact with data.
Continuously monitor data in motion and at rest and label sensitive assets according to your own security policies.
Reports and risk scores surface shadow AI usage, insider threats and misconfigurations so priorities are clear.
Redact sensitive data, revoke file access and trigger custom workflows in real time, with or without human approval.
