Battle-test AI coding models side by side
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.
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.
