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-moderated voice and video interviews that scale survey research to thousands of people at once
An AI moderator generates dynamic follow-up questions when an answer is thin, adding interview depth without a human moderator per session.
Respondents can answer by speaking, recording video, or typing, and teams can embed the same questions into existing survey platforms.
Every response is transcribed, translated, and themed with sentiment scoring and charts ready to drop into a report.
Built-in AI translation and transcription let one study reach audiences across more than fifty languages.
