As someone who doesn't use any of the more "advanced" features on sites like ChatGPT or Claude (agentic mode, memory, image generation, deep research, etc), I found the bloat of these services, both in UX and in performance, to be pretty tedious. There are a million AI chat interfaces out there, but I could never find one that just did simple messaging and history in the most minimal and lightweight way possible. So I made my own. Nully is written in Go and Vanilla HTML/CSS/JS. It literally just sends messages to OpenRouter, receives the result, and stores your messages locally. It's very simple, very clean, and very lightweight (see performance graphs on the site). It has basic chat features, basic model settings, and works with just about any OpenRouter text model.

It wrote the script, cut the edit, built the motion, and rendered the whole thing start to finish. 49 seconds, below. The video's the fun part. The real story is the velocity: this is what one person and the current models ship in a week. Most businesses are still deciding whether AI is worth a proper look. That gap is the whole opportunity, and it's closing fast. See where your business stands. The scan's free, takes 60 seconds.
