ThatOne - The Visual Bridge for AI Web Dev

Don't describe it, just click it. Give your AI the perfect prompt for any web UI instantly.

https://that-one.com/ Most AI tools are "blind." They guess at your layout, hallucinate your CSS, and ignore your design tokens. ThatOne is the visual bridge that gives your AI eyes, turning anything you see on a live website into a high-fidelity, zero-guesswork prompt. Whether you're using Cursor, Claude, or v0, ThatOne ensures your AI builds exactly what you intended—down to the last pixel. 🚀 Three Superpowers for AI-Driven Dev 1. Live-Site Style Tuning Don't just copy code; edit the reality of the page. Select any element on a running website and tweak its styles live. ThatOne automatically generates the prompt needed to replicate those exact changes in your codebase. 2. Universal Spatial Mapping AI struggles with "where." Use our layout canvas to drag, drop, and order elements (buttons, grids, navbars) into a logical map. Export a spatial blueprint that tells your AI exactly where every component belongs. 3. One-Click Design System Sync Stop letting AI "guess" your brand colors. Instantly import your design tokens from your AI codebase. Apply your project's specific variables to any site on the fly to see how they look before you even write a line of code. 🎯 Who is this for? AI Developers: Build UI faster by providing better context to Cursor or Claude. UX/UI Designers: "Design in the browser" and hand off perfect prompts to devs. No-Code Creators: Modify existing sites and build new apps without getting lost in the inspector. 🔒 Privacy & Performance ThatOne is built for speed. It runs locally in your browser, respects your privacy, and doesn't bloat your dev environment.
