Jack

Jack gets stuff done.

Jack is the app where you name each teammate. Maria, Jonas and Aisha are examples of teammates you can create. Tell Jack what you need, like sorting your invoices, and your teammate does the job. It uses the Claude or ChatGPT you already pay for. You don't need to code or set anything up. It asks before anything risky, so you stay in charge.

A chat gives you an answer. Jack does the work.

An answer
Summarise September's supplier invoices.

42 invoices matched, 3 are late. Here is a summary you can use.

Still yours
  1. Copy it
  2. Format it
  3. File it
  4. Send it
Finished work
Summarise September's supplier invoices and send it to the finance team.
M

Done. I put it in your report template and filed it.

  1. Copied
  2. Formatted
  3. Filed

Maria wants to send the summary to the finance team. Is that OK?

Jack does the part that comes after the answer: the copying, the filing and the sending.

Add a teammate. Hand over the job. You make the decisions.

  1. 01

    Add a teammate.

    Give your teammate a name and a role, like Maria, document controller. Then Maria asks you a few questions. How do you work? Which rules do you follow? Where are your documents? You don't write any instructions.

  2. 02

    Hand over the job.

    Write it in a chat, the way you would ask a colleague. Your teammate works in your project's folder, on the AI app you already pay for. You hear back when you are needed.

  3. 03

    You make the decisions.

    Before anything risky, like deleting files, your teammate waits for your yes. Something went wrong? Go back to an earlier point in the chat, and your files go back with it.

Works like you

A teammate that does things your way.

Maria doesn't start from zero. You teach Maria once, in a short interview. After that, every job gets done the way you would do it.

  • Taught by a short interview.Your teammate asks how you work: how you name files, which rules you follow and what they must never do. You don't write any instructions.
  • Your rules, your folders, your tone.Point your teammate to your documents, and they read them. Then they write the way you write, like in your own emails.
  • Go back, and the files go back too.Say a teammate renamed 40 files the wrong way. Go back to an earlier point in the chat, and the old names return. Changed your mind? You can undo it, as long as the files haven't changed since.
  • Explains things in plain words.Every screen and every explanation uses everyday words, not technical terms. You don't need to know how AI works to use Jack.
Team planTeach one teammate, then share them with your whole team.
Coming

A lot of boring work happens in a web browser. Jack is coming to work there too.

  • It works in your own Chrome.That is the web browser you already use, with your own logins.
  • You watch it work.Hand over the job, like placing a purchase order. Then watch it happen on your screen, step by step.
  • It asks before anything risky.Risky steps, like submitting an order, wait for your yes. It works that way everywhere in Jack.
Your computer, too.Coming after the browser

This is for work in programs that have no web version, like an old desktop program. Some programs need your screen while Jack works in them. Jack will tell you which.

For illustration: browser use is still being built, and nothing on this page works yet.

Chatting with AI is fine, until you need the work done.

  • A colleague has AI doing a task. You can't copy it.

    Say someone on your team taught their AI to draft the monthly report. To use it, you would have to install it, set it up and keep it updated yourself, with technical tools.

    Jack sets it up for you.

  • You explain your job again, every chat.

    A chat starts from zero each time: your rules, your folders, the way you like things done. It is like training a new hire every morning.

    A Jack teammate learns your way once, and remembers.

  • It gives you text to paste.

    A chat writes the words. You do the rest, one copy and paste at a time.

    Your teammate opens the folder, does the job and asks before changing anything.

Work, not code.

If your work lives in documents, spreadsheets, email and the web, a teammate can learn it. Here are some jobs people hand over:

  • Finance and accounting

    • Invoices matched to purchase orders
    • Month-end reports built from scattered spreadsheets
    • Expenses checked against your policy

  • Administration

    • Meeting notes turned into to-do lists
    • Documents filed and renamed your way
    • Letters and forms from your templates

  • Procurement

    • Reminders sent to late suppliers
    • Quotes compared side by side
    • Contract renewal reminders

  • Legal and contracts

    • Clauses checked against your usual wording
    • Long agreements summarised
    • Expiry dates tracked so none slip by

  • HR and people

    • Job ads and interview plans
    • Checklists for new starters
    • Policy questions answered from your handbook

  • Sales and customer success

    • Background on a client before you call them
    • Proposals from your templates
    • Call notes turned into follow-up emails

  • Marketing and communications

    • Drafts in your house style
    • Newsletters from the month's news
    • Posts reshaped for each channel

  • Engineering and industry

    • Specifications, calculations and technical documents written up
    • Drawings and data checked against standards
    • Evidence that you follow the rules, and records of changes

  • Construction and projects

    • Progress reports from site notes
    • Change orders and information requests
    • Document lists kept up to date

  • Operations and logistics

    • Order and stock spreadsheets matched up
    • Delivery dates collected from supplier emails
    • Weekly reports on your key numbers

  • Research and analysis

    • Desk research with sources
    • Data cleaned and turned into charts
    • Long reports summarised

  • Education and training

    • Course material from your documents
    • Quizzes and exercises
    • Feedback drafts for each learner

And there is more. If you can explain the job to a colleague, you can explain it to a teammate.

Start on your own. Grow with your company.

  1. 1 · YouFree

    Your own teammates, on the one AI app you already pay for. Teach them tasks, and have tasks run on a schedule, like a check every Monday. Browse the public marketplace, where people share teammates and tasks.

    How it works
  2. 2 · If you want morePro

    Use more than one AI app. Jack gives each part of a job to the one that suits it. When one has reached its limit for now, the next carries on. Each keeps to your own plan with it. You also get the web app and remote access.

    Jack's pick
  3. 3 · Your teamTeam

    A private library where one person's teammates and tasks become everyone's. Say Ana teaches a teammate once, and the whole team can use them.

    Sharing
  4. 4 · Your companyEnterprise

    Company-wide rules no teammate can skip, a relay you host yourself for remote access, and one place to allow, pay for and review every teammate.

    For companies

Each plan includes the one before it. Prices will be announced before launch.

Pro · Jack's pick

Different AI apps suit different jobs.

  • Pictures and design

    Visuals, layouts and anything that has to look right, like a poster or a slide.

    ChatGPT, with GPT Image 2.5 for making pictures

  • Thinking things through

    Analysis, long documents and hard problems, like reading a long contract.

    Claude, for reading and reasoning

  • Your company's own AI

    AI that your company runs or has approved.

    OpenCode, with your company's own access keys

This line-up changes every few months. Jack keeps up, so you don't have to. Using more than one AI app is on a paid plan.

Team

Set it up once, and the whole team uses it.

Say Ana teaches a teammate to write the monthly supplier report. Everyone else on the team installs that teammate from your private library. Nobody needs to type commands.

For illustration: the shared library in the app isn't designed yet.
Enterprise

Your company decides what AI may do.

  • Rules no teammate can skip.Company rules, set as hard limits that Jack enforces on every teammate. For example: never email suppliers.
  • Remote access on your own servers.A relay you host yourself, so remote access goes through your own servers.
  • Your keys, your AI.Bring your company's own access keys and gateways, and AI that your company runs itself.
  • One place to see it all.Allow, pay for and review every teammate across the company.

Why Jack, and not just the AI app you already use?

  • I already have Microsoft 365 Copilot.

    Microsoft 365 Copilot works inside Microsoft 365, on your Microsoft 365 data. Jack works on your own computer, in your own folders, with the AI app you already pay for. It also goes back in time: rewind a chat, and your files go back too. You can use both.

  • I can do this with Claude myself.

    You can, if you set up the tasks and schedules yourself, in tools made for programmers. Jack sets this up by asking you questions, and remembers it for next time. It still uses the Claude or ChatGPT you already pay for.

  • The chat box is enough.

    For quick answers, it is. Jack goes on to finish the job. It copies, formats, files and sends, and it asks before it sends.

Welcome to Jack 👋

Jack builds no AI of its own.

It works with the AI apps you already pay for, and you can switch the day a better one comes along.

  • It uses your own logins and access keys, so what you already pay for keeps working.
  • You can go back to any earlier point, and your files go back too.
  • Jack runs on your computer, so your files and chats stay there.
  • We never read your work, and we never use it to train anything. Jack does note how the app is used and when it crashes. It never records what is in your files or chats.

Questions you might have

Do I need to know how to code?

No. You tell your teammate what you need in everyday words, like sorting your invoices. There is no code and no commands to type.

Do I need several AI subscriptions?

No. Free works with the one you choose. If you like, Pro lets you add more, so each job can go to the AI app that suits it.

Does Jack combine my usage limits?

No. Each AI app keeps its own limits, under your own login, just as its maker sells it. Jack chooses which one takes the next job. It never shares or pools accounts.

Can my team share what I set up?

Yes, on Team. You get a private library where your team shares teammates and tasks.

Can Jack use my browser or my computer?

Browser use is coming. Jack will work in your own Chrome, the web browser you already use, with your own logins, and you will watch it work. Using your computer comes after that. Some programs will need your screen while Jack works in them. Neither is available yet.

Which AI apps does it work with?

Claude and ChatGPT, which you can chat with. Cursor and GitHub Copilot, which developers use when they write code. OpenCode, which can connect your company's own AI. And Google's Antigravity, which Jack installs for you and connects to your personal Google account.

Where are my files and chats kept?

On your computer. Jack runs there, and your files stay in your project folders.

Does Jack read my work or use it to train an AI?

No. Jack builds no AI of its own, so there is nothing to train. We never read your work. Jack counts how the app is used and when it crashes, never what is in your files or chats.

Can Jack change my files or send things without asking?

Not by default. Before it changes your files or sends something, it asks, and you can say no. If something goes wrong, rewind the chat and your files come back too.

What happens to my Claude or ChatGPT login?

You sign in to it yourself, the way you already do. Jack does not store your login. What you send goes to that AI app under your own account, just as it does today.

What about security reviews for my company?

Companies use the Enterprise plan, which adds company-wide rules and a relay your own company hosts. Security and compliance questions go through that plan.

What does it cost?

Free, with one AI app of your choice. Pro lets you use more than one, and adds the web app and remote access. Team adds sharing. Enterprise adds company-wide rules and a relay you host yourself. Prices will be announced before launch.

Let's add your first teammate!
