I made the slowest, most expensive GPT▲74
This 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…

PolyGPT – ChatGPT, Claude, Gemini, Perplexity responses side-by-side▲26
I built PolyGPT to solve a problem I had: constantly tab-switching between ChatGPT, Claude, and Gemini to compare their responses. It's a desktop app (Mac/Windows/Linux) that lets you type a prompt once and see all three AI models respond simultaneously in a split view. Useful for: - Comparing technical explanations - Getting multiple perspectives on code problems - Fact-checking answers across models The app is free, open source, and runs locally - your credentials stay on your machine.

I built an LLM chat app because we shouldn't need 10 AI subscriptions▲58
I'm lost between ChatGPT vs Claude vs Gemini... which subscriptions to take? With Cursor and all these specific AI tools, I just wanted one simple chat app where I can use any model and pay only when I use it. Couldn't find one, so I built one. Pay only for what you use. Your prompts and docs, knowledge bases work with every model - no more copy-pasting between apps. Started as a personal project, but thought someone else might benefit from this too. https://prismharmony.com/chat What do you think?
