# Cube

> When agents can do the work, the bottleneck is the person’s judgment. In Cube the person talks and signs, everything that needs them is in one list, and what they decide the same way every time freezes into a program.

Cube is where a person hands recurring work to AI agents (lead generation, a daily briefing, a job search) and keeps only the decisions. The agents do the work and carry out what is approved, and the list gets shorter as decisions freeze into programs.

Cube runs the person’s own Claude Code or Codex account itself. It has no MCP server or API for an outside agent. The pages below are linked in their Markdown versions and need no account to read.

## Use cases

- [Use cases](https://www.usecube.io/use-cases.md): The list of the cases below.
- [Lead generation](https://www.usecube.io/use-cases/lead-generation.md): Any agent can find leads and draft the first message. In Cube you judge a night of them from one list, settle the pile in a sentence, and the kind you always reject stops coming back.
- [Daily briefing](https://www.usecube.io/use-cases/daily-briefing.md): Any agent can read the news and summarize it. In Cube you tick the few stories you want, settle the rest in a sentence, and the kind you never read stops showing up.
- [Job search](https://www.usecube.io/use-cases/job-search.md): Any agent can collect postings and draft applications. In Cube you decide the new roles from one list, and the kind you always pass on is settled before you look.
