Agentic skills intelligence for hiring, developing, and planning talent
Technical, business, agentic, behavioral, and diagnostic evaluations built around real job tasks.
Structured conversational interviews that give teams clear skills evidence early in the funnel.
A shared workspace where candidates solve real problems while interviewers observe how they work.
See where your workforce is strong, spot gaps early, and plan hiring, mobility, and redeployment.
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.
Offers broad multilingual AI detection and text humanization, but lacks GPTZero's detailed deep-scan reporting features.
