Show HN: ChatHawk – Ask once. Get advised by all the top models

I kept pasting the same question across several AI platforms to make sure I got the best answer. I found this process time-consuming, and difficult to compare the answers between platforms.

So I built ChatHawk.

It's a tool that lets you ask a question and have it answered by all the flagship AI models at once. These models are currently Gemini 2.5 pro, GPT-5, Grok-4 and Claude: Sonnet 4. ChatHawk also uses AI to get the best parts from each response to provide a 'Best of All Models' answer.

I've found it useful for these use cases: 1. When you want to make sure the answer is right. E.g. for calculations and legal or accounting questions. ChatHawk lets you check the AIs have the same answer. 2. Strategy questions. E.g. for negotiating contracts or salaries it is useful to get advice from each AI model... It's like having an AI board of advisors. 3. Ideation. For coming up with new ideas it's beneficial to talk to several AIs and see each response.

Some AI aggregation tools exist BUT they show the AI answers side-by-side or in a grid. I found this overwhelming from a user experience perspective. I wanted to see one answer at a time and click tabs to swap between them! So, I hope you enjoy ChatHawk's UX as much as I do :)

It's also incognito as ChatHawk doesn't save any message history. It's annoying how all AI platforms store chat history when it's not that useful a feature. In my view, they do this to data mine and build memories which lock you into their platform. So don't worry about that on ChatHawk.

Please let me know if you have any feedback. The tool is free to use with no paid option at the moment...
