I made Sophon, a minimal AI chat app for the browser. It’s like Cursor, but for tabs. It's sidebar chat with context and autofill, supporting the latest OpenRouter models. While this app idea is not particularly original, I’ve been highly opinionated on these types of products. Since playing around with the OpenAI API, I’ve had this vision of a cohesive chat app that interfaces perfectly with the browser. It’s to the point where this is the only thing I want to work on. Switching tabs and copy/pasting into GPT just feels wrong. It feels slow, clunky, and distracted. And while other apps do the same thing, the product never seems quite right. Half of the apps simply don’t parse markdown or handle streaming. Other times, the browser part of the app feels like an afterthought. Sometimes I need to click to access the tab, or endure bloated features that clutter the browser. I wanted to unify the browser and chat, not glue them together. I want read and write. I want some cohesive, intentionally designed, minimal experience. So, I’ve tried my best. I'd love to hear your take on this project!
