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.

AI hiring OS that scores candidates and preps your interviews
Applications are parsed against your specific technical criteria, and every candidate receives a match score with a short AI rationale explaining the fit.
Before each call, the platform drafts a brief listing strengths to verify and red flags to probe, keeping interviews structured and consistent.
Interview transcripts are analyzed to pull out signals and evidence, so hiring decisions rest on what was actually said rather than memory.
Ask plain-language questions about candidates and the pipeline, and get answers synthesized from profiles, transcripts, and team feedback.
