Everything chatgpt.com does — plus features that only exist when multiple AI models work together.
Send the same prompt to ChatGPT and other models simultaneously. All responses stream side by side in real time — no tab-switching, no copy-pasting. See which model gives the better answer for your specific question.
Example: "Explain the pros and cons of microservices vs monolith"
AI Collaboration lets ChatGPT draft an answer, then Claude reviews it for errors, Gemini verifies facts with web sources, and the system merges the best parts into one final response. You get a single answer built by multiple AIs — stronger than any model alone.
ChatGPT text sounds like ChatGPT. The AI Humanizer rewrites it using a different model so the output matches your actual writing style — not a generic "human tone." Upload your own writing samples and the system learns how you write. Every rewrite after that sounds like you.
ChatGPT output
"In today's rapidly evolving landscape, it is imperative to leverage strategic initiatives..."
After humanization
"If you want better results, fix how your team actually works."
