# Alpha documentation

> Describe what you want built. Alpha's agent builds it on its own machine, shows it to you live, and publishes it when you're ready.

Alpha is a workbench for building software with an AI agent. You describe the result in the chat; the agent writes the code, runs it on the session's own machine and shows it to you in a live **Preview**. When it looks right, **Publish** puts it on the internet at its own address.

It ends with the agent's message that three choices will shape the plan, a card titled The agent has questions with a green check, listing three questions each answered Left to the agent — it went with In app only, Until class starts and Current browser, and a Proposed plan card titled Automatic class waitlist with a copy button and a chevron. The composer below shows the placeholder Describe what to plan…, then the + button, the model chip reading gpt-6.… · high and the plan chip reading p… · on on the left, and the microphone and a dimmed round send button on the right.

## Every session has its own machine

Each session runs on an isolated cloud machine where the agent installs packages, starts servers and runs commands without touching any other session. Turns run on Alpha's servers, so work keeps going when you close the tab. After about 30 minutes away, an idle machine sleeps; opening the session wakes it with every file as you left it.
