Powerful Features

Reflect Your Thinking on AI

Single-AIs predict text. MultipleChat builds reasoning. Using the same information, distinct AI models engage in questioning, analysis, and idea refinement. With customizable AI Collaboration settings, you can influence how this process develops, enabling the same question to yield varied responses depending on the reasoning framework. MultipleChat enables users to produce texts that reflect their own thinking so each user can get a different answer to the same question.

Prompt Optimizer

Turn Your Ideas Into Perfect Prompts

This is why using multiple AI feels fundamentally different. A single model can’t truly step outside itself to improve its own prompt. With MultipleChat, one AI helps design the prompt, while another answers it. The Optimizer fills in missing context, clarifies intent, and structures the request — so each model responds with more depth, accuracy, and consistency.

Audience aware Tone & format aware Model-ready prompts

Before
