Browser Buddy

Browser Buddy is a tiny browser extension that lets you completely reshape any webpage: hide clutter, restyle fonts and spacing, tweak colors, rewrite or remove blocks, run quick scripts, and poke the DOM—without living in DevTools. You get direct visual control plus a lightweight console / debugger path when you need to go lower.

It showcases GPT‑5‑nano: a dirt‑cheap, very fast, not‑that‑smart model that’s perfect here. You type "tighten line height and mute the sidebar ads" (or similar); the nano model proposes a set of DOM edits; you accept or hit quick retry if it missed. Because responses cost almost nothing and land in a blink, iterative retries are encouraged—great for the messy variability of real world markup. This is the point: some tasks don’t need a giant model; they need a tiny one that can fail fast, try again, and converge while you watch. That loop (prompt → attempt → visual check → retry or keep) makes the web feel malleable and personal.
