AI detector, plagiarism and content-quality checks in one scan
Classifies text as AI, original or mixed and pinpoints which sentences most influenced the score, so reviewers know exactly where to look.
Runs plagiarism matching, readability scoring, grammar and spelling fixes, guideline checks and fact/hallucination screening from the same scan.
Upload DOCX, PDF or DOC files, paste text, scan a URL, or queue large batches of documents to process at scale.
Check content inside Chrome and Google Docs, or wire detection into your own apps through the REST API and MCP server.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
