Work management with AI agents that finish the job.

Agents turn briefs into memos and decks, tidy your backlog and draft your plan. You have the final say.

Free for up to three people once Arbituro opens. No card needed.

A job page titled ‘Black Friday: run the 20% offer again?’ with its brief, a two-line done-when checklist, a delivered memo waiting for review, and the agent Iris’s desk on the right.
The brief, what done means and what was delivered, with the agent beside it.

Why Arbituro

Arbituro puts AI agents to work beside your people. Every change an agent proposes waits for a person to accept it.

Done when

Work comes back the way you meant it.

Every job carries a short checklist of what done looks like, agreed before the work starts. The agent works to it, and you judge the result against it.

A job’s brief asking for a one-page memo comparing two years of Black Friday results, with one cited source.
A done-when checklist with two lines, each naming who ticks it, and ‘Sam Taylor judges’.
A brief with its source attached. Each line of done says who ticks it.

Your turn

Start your day with what needs you.

Your turn gathers the decisions only you can make into one queue. When something is waiting, a morning brief tells you in Slack or by email.

Stepping through Your turn with the keyboard: a request to accept, a job that starts today and an email waiting for approval.
A request to accept, a job that starts today and an email to approve, one at a time.

Approvals

Nothing leaves the building without you.

Agents draft the email, the message or the change in another system. Only the person who owns that connection can send it, and every send is on the record.

An approval card for an email: tool call, external side effect, the sender, recipient and subject, the full message, where the address came from, which done-when line it ticks, and Approve and Deny buttons.
Exactly what goes out, and to whom, before it goes.

Deliverables

Agents hand in finished work.

Ask for a one-page memo or a ten-minute deck and you get exactly that, in your brand and ready to print or present.

A one-page memo on Cinderwood Coffee letterhead, with its logo, recommending against repeating a Black Friday discount, in sections What I recommend, What the trade-off shows and What to decide.
A decision memo, on your letterhead, with its sources footnoted.
A slide from an agent-written deck for Cinderwood Coffee. Title slide: ‘Bring the spring blend back next year’.

Every slide of a deck an Arbituro agent wrote, in the workspace’s brand. It has speaker notes and downloads as PowerPoint.

Sign it off against what you agreed.

The review room for a slide deck: the deck’s first slide fills the screen with slide thumbnails beside it, the done-when drawer open at the right with three clauses each marked Waiting on you with Met and Not met, and Accept and Reject in the bar above.
The review room after judging: every done-when clause ticked by Sam Taylor, the bar reading Verdict Accepted with Every clause is met and a bright Mark it done button, and a judgment record noting the review took seconds.
The deck full size, with what done means beside it. Then every line met, and the verdict recorded.

Backlog

A tidy backlog, without the clean-up meeting.

The project’s agent reads the jobs that haven’t started and proposes changes, like dropping a repeat or splitting a vague job into parts. Each change gives its reason and waits for you.

A band reading ‘Iris proposes 4 changes to the backlog’, what it read and what it cost, with a bright Review 4 changes button.
Three proposed changes drawn under their jobs: hand a job to Priya Raman, drop a repeat of MKT-10, and split a Christmas gift box job into four named parts, each with its reason.
Each change sits under the job it changes.

Timeline

Let the agent draft the dates.

It fills in dates for the jobs that have none, working from their order, due dates and who is busy. Once you apply them, agents start work on the planned day.

A timeline of jobs across October and November with today marked, bars for each job, a parent job’s span, and a tray of jobs without dates.
Dates where they matter, and a tray for the ones still to plan.
The drafted-dates band and the timeline beneath it, with dashed bars for the jobs the agent dated.
Dates proposed, explained, and waiting for you.

Ask

Know where the work stands.

Ask what’s left before a launch or what’s running late. An agent answers from the project’s jobs and documents, in a conversation the whole team can see.

A question about a coffee launch and the agent’s answer: four jobs with their owners, due dates and what each is waiting on.
An answer that names the jobs, their owners and their due dates.

Routines

Recurring work, done on schedule.

An agent can triage support every weekday morning or check freight once a month, and hand anything it finds to a person as a job.

Routines: a weekday support triage, a Monday reviews round-up and a monthly freight check, each with its agent, schedule and next run.
Each routine, with its agent, schedule and next run.

Connections

Agents work in your team’s tools.

They read and draft with only the access a person shares with them, and that access can be taken back.

  • Microsoft 365Mail, calendar, files and Teams
  • Google WorkspaceGmail, Calendar and Drive
  • SlackChannels and messages
  • GitHubRepositories and pull requests
  • Jira and ConfluenceIssues and pages
  • SalesforceCRM records
  • HubSpotContacts, companies and deals
  • XeroContacts and transactions
  • DocuSignEnvelopes
  • NotionPages
  • ZoomMeetings and recordings

Bring your coding agent

Claude Code, Cursor and VS Code connect over MCP as you, and work from the same brief as everyone else.

Bring your backlog

Import a CSV export from Jira or Linear, or any CSV with a title column. You see what will come in first, and importing the same file twice is safe.

Mobile

Clear your turn from your phone.

Judge the work and record your verdict wherever you are. Arbituro installs to your home screen.

Your turn on a phone showing a wholesale enquiry with Read it and Accept.
A job page on a phone with its brief, source and done-when checklist.
The one-page memo reflowed for a phone.
The whole job, at phone width. Read the memo on the train.

Start free, then pay per seat.

Free workspace

A new workspace is free for up to three people, with a monthly allowance of AI credits.

Plans

Billed per seat, monthly or yearly, each with a monthly allowance of its own. Adding a colleague adds their seat.

Credit packs

Top up when a month runs heavy. Packs never expire, and the monthly allowance is used first.

Plans will be announced shortly.

Questions

Can an agent send an email or post a message on its own?

No. The person who owns that connection has to see it and approve it first.

What can an agent read?

The brief and sources on its job, the documents you have published to the vault, and any connection a person has shared with it.

How do I know what an agent did?

Every run keeps a record, in plain English, of what the agent read and which tools it used, in the order it happened.

Which AI models does it use?

Models from OpenAI, Anthropic, Google, Mistral and others. Which ones a workspace can use depends on its plan.
