Add Applet as a connector.
In the Claude or ChatGPT app, open the connectors list, choose Add custom connector, name it Applet and paste the address. Sign in to Applet once and allow it.
Tell it your idea.
No laptop, no setup. The agent creates the app on Applet, writes it, tests it, and gives you a link that only you can open.
Ask for changes in plain words.
The agent reads what is there, edits a draft, and checks the result. When you authorize a live update, it can check and publish in one workflow.
Share it when you are ready.
Apps stay private until you say so. Ask the agent to make it public and send the link; your friends open it on their phones.
The app and URL in this example are illustrative, not a deployed app.
