* [Choose Chat or Work](/use-zerotwo): Use Chat to explore a question or shape an idea. Switch to Work when you have a clear outcome and want ZeroTwo to plan, gather context, and carry a larger task through to a reviewable result.
* [Choose the right model and reasoning](/models): Select a model and reasoning level from the composer. Start with the default effort, then increase it when a task needs deeper planning, analysis, or a larger multi-agent run.
* [Bring in tools and repeatable workflows](/skills-and-plugins): Install plugins to connect services such as Google Drive, GitHub, or Slack. Add skills when ZeroTwo should follow a specific workflow, use team guidance, or produce work in a consistent way.
* [Create and refine finished files](/artifacts-viewer): Use ZeroTwo Work to create a document, presentation, spreadsheet, or PDF from your source material. Review the result in the chat, request focused revisions, and download the finished file when it is ready.

* [The work depends on your tools and context](/skills-and-plugins): Use plugins and skills to bring in connected sources, take action, and follow repeatable workflows.
* [You need a file you can review and share](/artifacts-viewer): Turn source material into a document, presentation, spreadsheet, or PDF, then refine it through feedback.
