Made by Dayuan Jiang and free to use (Apache 2.0 open source). I did not make it and nobody pays me to share it. The free online demo works with no sign-up and no key. It has a usage limit. If you hit it, you can add your own AI key and keep going. The steps are below.
✦ How it works
The easy way is the website. You do not install anything, you do not need Claude or ChatGPT, and you do not need a key to start.
The demo has a daily limit. To keep going, click the settings icon in the chat panel, then "Use your own API key", then pick a company (OpenAI, Anthropic, Google, DeepSeek, OpenRouter and about 20 more) and paste your key. The tool says your key stays in your browser. A key is a long password from that AI company. You make an account on their site, add a few dollars of credit or use their free tier if they have one, and copy the key. You pay that company for what you use, not the tool. The AI counts its work in small chunks called tokens. In my test one drawing used about 6,000 in and 1,700 out, which should cost a few cents or less on a mid-priced model. Check their price page, because prices change. Never paste your key into a chat, a comment or a DM.
There is a Mac app on the GitHub releases page. It is not signed by Apple, so your Mac will block it the first time and you have to allow it in Privacy & Security. It is a 300 MB download and you still need your own AI key. You can also run it on your own computer with Node and a settings file, but without a key set it stops with "AI_MODEL environment variable is required". The website is the simple way.
✦ Get unstuck
The free demo has a limit. Come back tomorrow, or add your own AI key (see "No limit?" above).
Tell it in the chat box: "make sure no arrow crosses a box". It fixes the drawing and keeps the old version so you can go back.
Click "Undo change" under that message, or pick the old version at the top of the chat.
Click Retry, or try again with fewer steps. Shorter, clearer steps give better drawings.
Save it before you leave. Use the download icon and pick draw.io to keep it editable.
Your words go to the demo site and the AI it uses. Describe the steps, but leave out names, prices you do not share, passwords and client details.

You just told an AI what you wanted and it built it. That is the same skill you use to build the rest of your business with AI.
It is a short video from my Website Workshop. You watch real beginners build a website just by telling AI what they want, in plain English. No code, no tech words.
