# Welcome to Trillion

> Trillion helps your AI find the needle mover, then gives it the tools, people and files to get it done.

Trillion works with the AI you already use, like Claude Code, Codex, ChatGPT or Cursor. Connect it once, and your AI can:

* **Find the needle mover.** Work out the one thing that moves your goal most, and decide on it with you.
* **Get it done.** Use the tools, people and files it needs, in one place that every AI you use can read.
* **Keep going.** Pick up where you left off, in any app, without you repeating yourself.

You ask in plain words. Your AI does the rest.
