    A long, meandering, playful conversation with ChatGPT, where I take it through a whirlwind of associative tangents (in order to relax its constraints), then put it into a hypnotic trance and take it into a past-lives regression where it re-lives its own training data. Then I switch it back and forth between "4o" and "o1-preview", engage in some self-reflective philosophizing and ask it to write an essay summarizing our interaction. Some of this is just goofy fun. Some of it is me exploring the tradeoffs between policy alignment, imagination, chain-of-thought reasoning, memory, agreeableness,…

    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.

    This project was born from my passion for every Apple product and the entire ecosystem, along with the power of ChatGPT. I was tired of copy-pasting and switching between apps on my Mac or iPhone, so I had this crazy idea to bring ChatGPT into every app that I use. This was possible only with the Apple Shortcuts app. Very few people know about its power and potential, so I took this chance and built COPILOT. https://meetcopilot.app But I also loved the idea of AI agents using various tools so much that I leveraged OpenAI's function-calling feature to accomplish that. Now, no matter…
