AllChat AI is a multi-model AI chat app built around a simple idea. Instead of picking one AI and hoping it gets your question right, why not ask several at once and combine their answers into one better response? Most AI apps give you one model's opinion. AllChat gives you all of them. Consensus...

As answered by people managing AllChat AI and Diffyn.
AllChat AI's answer
Most AI apps give you one model's opinion. AllChat asks several top AI models your question at the same time, including GPT, Claude, Gemini, and Grok, then combines their answers into one smarter response using Consensus Mode. You can see exactly which models agreed, where they disagreed, and how the final answer was built. Smart Routing also picks the best models for each specific question automatically, so you never have to guess which AI to use.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
AllChat AI's answer
AllChat is the only app that combines multi-model consensus with smart automatic routing in one place. Other multi-AI apps just let you switch between models or chat with them side by side. AllChat actually synthesizes their answers into one better response and shows you the work behind it. It also has features competitors don't, like Smart Alerts for background monitoring of topics you care about, ChatGPT memory import so you can switch without starting over, and on-device models for fully private offline use.
Diffyn's answer:
Diffyn is the platform that specializes on both change management and multi-model analysis.

AllChat AI's answer
People who already use AI chat apps regularly and want better answers without doing the work of comparing models themselves. That includes students, researchers, developers, writers, and anyone who has ever pasted the same question into ChatGPT and Claude just to see which one got it right. AllChat is for users who care about answer quality and want transparency into how their AI works.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
AllChat AI's answer
AllChat started because picking the right AI model for every question is exhausting. New frontier models come out every month, each one is better at different things, and getting it wrong means worse answers. Instead of forcing users to choose, AllChat asks several at once and combines their answers into one best response. The transparency panel exists because black box AI is frustrating and people deserve to see how their answers came together.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
