Hey Product Hunt 👋
Quick bit of background on why this exists: I'm a technical PM in my day job, and I started Vellio as a small side project. Honestly, it was just to force myself to get more hands-on with code and stay in sync with my engineering team. It was never supposed to be a "thing."
Then it took over every evening and weekend for months. One feature turned into ten, and at some point I looked up and realized I'd built a full AI workspace: chat with any major model, compare two side-by-side on the same prompt, search the web with real cited sources, and (my favorite part) ask it to actually build you a spreadsheet or document you can download and keep editing.
After months of iterating mostly by myself, I figured it was time to stop tinkering in private and see what real users think. So here it is. I'd love your feedback, good or brutal, doesn't matter. Happy to answer anything about how it's built, model routing, pricing, or what's next (mobile, a browser sidebar assistant, and an API are all on the roadmap).
