Before you start
You need an account on app.rerun.build. Rerun starts with a 5 day free trial. Nothing to install. Everything happens in the browser.1. Sign up
Open app.rerun.build. You land on the board, the isometric view where your Boxes and coworkers live, with a sign-in dialog on top. Right after signing up you answer three short questions about your sector, your team size and your role. They only decide which templates you get shown first.2. Pick your first coworker
The template library opens on its own, filtered on the sector you picked. Two ways forward:- Install a template
- Start from scratch
A template is a setup that already works: a prompt, skills, scheduled tasks and the apps it needs. Pick one, and Rerun creates the coworkers it contains in your account.
3. Place it on the board
The toolbar switches to placement mode. Tap a tile and the coworker takes its spot. Your first coworker needs a Box, and Rerun draws one for you. Behind it, your workspace claims its machine from a pool of ready ones: a private cloud computer, isolated from every other account, that hosts every coworker you place. It takes a few seconds.4. Run the guided setup
A coworker that came from a template usually needs to be connected to your own accounts. When it does, the chat opens on a Start installation button instead of a message box. Click it and the coworker walks you through its own setup: it tells you what it needs, offers to install the apps it is missing, and asks you for the values only you can give. You answer in the chat, exactly like a conversation.When it needs an API key, the coworker opens a masked form. The value goes straight to your machine and is never shown to the coworker or stored in the conversation. Never paste a secret into the chat itself.
5. Talk to it
You now have a normal message box. Ask it for something. While it works you see every step: the files it reads, the searches it runs, the tools it calls. If it needs a decision, it stops and asks you, right in the chat.6. Let it run without you
Two ways to make a coworker work while you are away.Scheduled tasks
A cron and an instruction. Every Monday at 9, summarise last week and email it to me.
