Ithy AI▲167This is another one of my automate-my-life projects - I'm constantly asking the same question to different AIs since there's always the hope of getting a better answer somewhere else. Maybe ChatGPT's answer is too short, so I ask Perplexity. But I realize that's hallucinated, so I try Gemini. That answer sounds right, but I cross-reference with Claude just to make sure. This doesn't really apply to math/coding (where o1 or Gemini can probably one-shot an excellent response), but more to online search, where information is more fluid and there's no "right" search engine + text…

ChatHawk▲13I 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.

E.g. for…
