Describe it.
Your agent designs it.
1DesignTool turns the coding CLIs already on your machine into a design studio. Real files, live preview, no subscription.

No credits. No API keys. The subscription you already pay for does the designing.
Ask for a black hole. Get a black hole.
The 3D template ships interactive three.js scenes. This one is running right here: orbit it, drag the tweaks, take the file.
Orbit it
Scenes ship interactive: drag to orbit, scroll to zoom, right-drag to pan. The result panel is a real viewport, not a render.
Tweak it
The agent exposes live controls: spin, glow, palette, trails. Drag a slider and the scene answers before anything saves.
Keep it
Export GLB or PNG straight from the canvas. The file is yours, no watermarks, no export credits.
running live on this page, exported GLB included
Watch a sentence become a project.
A run is not a black box. You see what the agent is doing as it does it, and the result panel fills in live.
Describe
Type a brief, pick a template, choose the agent, model, and effort. Attach files or link your code for context.
Watch the run
Every tool call becomes readable activity: copying starter, writing files, reading logs, taking screenshots. Each file lands as a card.
Keep the files
The preview reloads as files change. When the turn ends, the app snapshots the folder so you can always roll back.

a run, mid-flight: steps on the left, live preview on the right
One studio. Twelve kinds of output.
Each template ships starter files, instructions for the agent, its own viewer, and checks that match the format. A wireframe is just one of them.

Quality is a gate, not a prayer.
Every project installs the design kit: a fixed procedure, visual directions, starters, and a checker the agent must pass before you see the result.
13 directions, not one guess
Each run picks a visual direction with generated tokens, a signature move, and rules with numbers. The agent designs inside the system, not around it.
The gate decides pass or fail
Screenshots at real sizes, contrast checks, overflow, font sprawl, missing assets. Failures turn into lessons. Passes ship to the preview.
It learns, you approve
Lessons, dropped-in examples, and extracted house styles become proposed knowledge cards. Ask for options and every pick between variants teaches it your taste. Nothing changes future runs until a person accepts it.
Point at the thing. Say the change.
Follow-ups do not start from a blank prompt. Aim at the design itself and the agent knows exactly what you mean.

Click any element in the preview and your next message is aimed at it.
Pin notes on the design itself. The agent reads them with position and context.
Sketch an arrow or circle the thing that is wrong. Pixels become instructions.
Agents expose sliders, swatches, and toggles. Drag, preview, save back to the file.
Files are the truth.
A project is a normal folder on your disk. No proprietary document, no cloud workspace, nothing between you and the output.

Open out
Standard formats that open anywhere. Hand a deck to a client, a model to a printer, a folder to a developer.
Private by default
No account, works offline, nothing leaves the machine except through the agent CLI you picked.
Never lose work
Every turn takes a snapshot. Restore is one click, and Stop always works.
Design systems are packages
Tokens, fonts, logos, and usage rules built from your repos or brand files. Pick one per project, or let the Brand template turn a finished kit into a reusable system.

Buy once. Own forever.
No seats, no credits, no renewal screen. The license is tied to you, not your computer, and it never expires.

Yes, at least one. 1DesignTool drives the CLIs you already have: Claude Code, Codex, Grok Build, Cursor Agent, OpenCode, Antigravity, and Qwen Code, with more added as data files. It detects what is installed on first run. No API keys and no credits: your existing subscription does the designing.
Real files. A project is a folder of HTML, CSS, JS, and assets that opens in any browser, commits to git, and hands off to a developer. There is no proprietary document and no cloud workspace to lose access to.
The app does. Projects, previews, templates, design systems, and the design kit all live on your machine. The only thing that touches the network is the agent CLI you chose, and only while it runs.
After 14 days the app becomes a free viewer: projects still open, present mode still works, and exports carry a small watermark. Editing unlocks again the moment you activate a license, and people you share files with can always view them for free.
Both, with one license covering up to 3 machines. Linux is a stretch goal on the roadmap.
