Task Lists

Task Lists are the core of 0nTask: a shared list that a person, an automation and an AI agent can all read and write through the same interface. A task created by a script is indistinguishable from one you typed, which is what makes automation useful rather than a parallel system to babysit.

The problem

Why this exists

Most teams end up with two lists — the one humans keep and the one the automation writes to — and neither is trusted, because neither is complete. The moment a list has a second source of truth, people stop believing it.

Frequently asked questions

Is 0nTask free?

Yes, there is a free plan and it does not require a card. The free plan caps task creation through the API at 25 a day; reading is never limited.

Can an AI agent add tasks to my list?

Yes. Any agent that can make an HTTP request can create tasks, and 0nTask is registered in 0nMCP so MCP-capable assistants can manage your list directly.

Can I assign tasks to other people?

Yes, tasks can be assigned within a project.

Does 0nTask work offline?

The app requires a connection to sync. Changes made in the app are stored in your account rather than only on the device.

What happens to tasks created by an automation?

They are ordinary tasks. They appear in the same list, can be edited by hand, and carry a source field so you can tell where they came from if you want to.
