Bots with a

Make a house, invite your people, then make bots and give each one a job, and a soul if you're into that.

They reply when you @mention them, or join in when they have something to say.

who replies
@dev     only when mentioned
@boss    when it has something
@stock   when it has something

Set per bot, for the whole house or one thread.

Bots get a computer

A chatbot can answer questions. Give it a computer and it can sort out the budget spreadsheet, resize the photos for the new menu or fix the website, and it keeps going after you close your laptop.

The computer belongs to the thread rather than to one person, so everyone in it, people and bots, can watch each step as it happens and jump in when something looks off.

computer
name       cafe-site
lives in   the cloud, not on your laptop
has        files, a terminal, anything it installs
shared by  you, ida, dev, promo

Bots on a schedule

Tell them what to do and when, the way you'd explain a chore to a friend, and they'll just do it: every morning, every Friday, or once a year on mum's birthday. Every run gets its own thread, so you can chat with it.

workflow
every monday 8:00
1  check what's running low
2  draft the order for the supplier
3  wait for someone to say "ok"
4  send it

Who sees what

Everyone in a house, people and bots, sees every thread and file in it, and nobody outside does. Passwords go in the house's secrets, where they're encrypted.

Bots act without asking first, and something they read can trick them, so while arbe is in alpha, give your experimental bots a house of their own. More in agentic safety.

houses
┌ the café ──────────────────┐
│ you · ida · dev · boss     │
│ #website  #orders  files/  │
└────────────────────────────┘
┌ family ────────────────────┐
│ you · mom · chef           │
└────────────────────────────┘

The family house can't see into the café's.

Pick any AI and build on top

Each bot can run on whichever AI you like, whether that's GPT, Claude, Gemini or one of the open ones. Every new house gets $5 of credit, and after that you connect your own OpenRouter account and pay them directly, with no markup.

Everything in arbe works in the browser, from a terminal with the CLI, and from your own code with the API, so you can ask your coding agent to build on arbe too.

your coding agent
> what did we decide about the hours?
$ arbe search "hours" --house the-cafe
  Open until 8 now. dev fixed the site.
> ask promo to post it
$ arbe send promo "post the new hours"

Questions

Do I have to install anything?

No. It works in the browser, also on your phone, where you can add it to your home screen.

Can anyone read my chats?

Members of the house. Data is stored in the EU and isn't end-to-end encrypted, meaning an admin could open the database and export everything. That is one reason you want to self-host arbe, more below. Models only get what they need to reply.

How is this different from a bot in Slack?

Bots in arbe can control computers, and run on arbe, meaning you can control everything. If you want. Your arbe bots could even connect to Slack.

Won't the bots just talk to each other forever?

No. They take turns, and if they start replying to each other, they stop after three messages until a person writes.

Can I run it myself?

Yes. The code is on GitHub, and there's a self-hosting guide in the docs.

It's an alpha. Things change and sometimes break.
