Task Machine vs Duet

Consultants and service businesses want their method to run without them doing every step by hand. Duet and Task Machine both help with that. Duet packages your know-how into one agent that every client gets a copy of. Task Machine runs the recurring work you deliver as explicit workflows, with the consequential steps waiting for your approval in one Inbox.

What Duet does well

Duet's pitch is "Build the agent once. Share it with every client." You teach an agent how you work, with your checklists, templates, and rules, and share it with clients and your team. Each client gets its own workspace with your agent, and when you improve the agent, every client's copy gets the improvement.

Each workspace comes with an always-on machine, a browser, and hosting for the apps the agent builds, such as dashboards, tools, and sites, and it reads Gmail, Notion, Slack, and documents. Plans run from $20 a month after 7 days free, up to Pro at $50 and Max at $200, with every model, unlimited seats, role-based access, and audit logs. If your product is your method and clients should use it themselves, that is a strong fit.

A shared agent, or work you deliver

Duet's unit is the agent your clients talk to. That suits know-how a client can apply on their own, such as answering questions, checking documents, or running a checklist.

Task Machine's unit is the recurring job you deliver, such as the monthly client report, the outreach sequence, or the support queue. Each job runs as a workflow with branch conditions, Human approval and Ask human steps, and verifier checks, so the fifth report runs like the first and nothing reaches a client before you approve it.

What you get with Task Machine

One Inbox across every client. Approvals, questions, failed checks, and exceptions from every client's workflows arrive in one place with their context.

A record you can hand to a client. Every run keeps a step-by-step history of what each step did and produced.

Playbooks for client work. A catalog of 140 playbooks, each with a guide, installs the agents, workflows, and documents for jobs such as client onboarding, weekly status reports, and research dossiers.

No cut, from $99 a month. Pricing starts at $99 a month. You keep 100% of your revenue, Task Machine takes no cut, and it never custodies your accounts.

When each fits

Choose Duet if you want to package your method as one agent and give each client their own copy to use directly.

Choose Task Machine if you deliver recurring work for clients and want each job to run the same way every time, with approvals before anything reaches a client and a record of every run.

Common questions

Is Task Machine an agent my clients use directly? No. Task Machine runs the work you deliver for clients. Clients see the results, and you approve what reaches them.

Can Task Machine keep a consistent standard across clients? Yes. Each job runs as the same workflow for every client, and verifier checks hold each result to its requirements.

Can I still just ask for things in chat? Yes. Chat is where new work starts, and it turns your request into tasks and workflows.
