JackComing soon · Waiting list open
Hand off the work.
Keep the decisions.
Jack is a coworker for AI agents. Your team describes the outcome, Jack puts the right agent on it, and you get back results and the decisions only people should make.
The work is ready for agents. The tools are not ready for your team.
Agents can already do real work
Today's AI agents read documents, fill in spreadsheets, draft reports, use a browser and write the small programs that glue it all together.
But they are built for developers
Each vendor ships its own agent with its own tools, set up in a terminal. Your finance or engineering team should not have to become programmers to use them.
And every vendor wants to be the only one
Pick one and you are tied to its models, its prices and its roadmap. The best agent for a job changes every few months.
How it works
- 01
Describe the outcome
“Reconcile last month's supplier invoices against the purchase orders and list the mismatches.” No prompts to engineer, no code to read.
- 02
Jack puts the right agent on it
Claude, Codex, Cursor or another agent your company allows, running with your own API keys or gateway. Agents can hand parts of the job to each other.
- 03
You review and decide
You see results, not code. Your company's own rules decide which actions need a person's approval before an agent can take them.
Built for the whole company
Agents write code when a problem needs it. That is how they work, not what you have to look at.
Administration
- Invoice and purchase-order reconciliation
- Monthly reports from scattered spreadsheets
- Procurement and supplier follow-up
Engineering and industry
- Specifications, calculations and technical documentation
- Checking drawings and data against standards
- Compliance evidence and change records
IT and platform teams
- One place to allow, fund and audit AI agents
- Your API keys and gateways, no personal subscriptions
- Company rules that agents cannot skip
Open where it matters
Jack does not build its own agent. Each AI vendor is best placed to tune its own, so Jack works with theirs and lets you choose, job by job.
- Free, open runtime. The engine that runs and connects the agents will be free and open source, so developers can build on it too.
- Any agent. Use the agents your company already trusts, and switch without starting over.
- Your keys, your data. Agents run with your own API keys or gateway, under your company's rules.

We are opening Jack to a small group of teams first. Tell us a little about yours and what you would hand to an agent.
Questions
What is Jack?
A desktop and web app where your team hands work to AI agents and reviews the results. Underneath is a free, open runtime that starts the agents, lets them work together and keeps track of every job.
Which AI agents does it work with?
The runtime already drives Claude Code, Codex, Cursor, OpenCode and GitHub Copilot, plus agents that speak the Agent Client Protocol. More will follow.
Does my team need to know how to code?
No. Agents write code when a task needs it, but your team works with outcomes: files, reports, answers and approvals.
What will it cost?
The runtime is free. The desktop and web apps will be paid; pricing will be announced before launch, and people on the waiting list hear first.
What happens when I join the waiting list?
We read every sign-up. We will contact you about early access and the launch, and nothing else. You can ask us to delete your details at any time.
