When a task produces a file, give ZeroTwo the source data, expected file type, structure, and review criteria that matter for the task. The preview and review tools depend on the surface you use.
The ZeroTwo desktop app previews generated documents, presentations, spreadsheets, and PDF files alongside the chat. When automatic previews are enabled, the app can open a generated file after a task finishes.When HTML previews are available, generated .html and .htm files can also open as interactive previews. Switch between the rendered preview and source view to inspect the output or its underlying HTML.Use annotations to point at a specific part of a supported preview and request a focused revision.

​
Create files for review

For spreadsheets and presentations, describe the sheets, columns, charts, slide sections, and checks you expect. Ask ZeroTwo to explain where it saved the output and how it checked the result.

​
Refine files with annotations

Annotations let you point to a specific part of a file and tell ZeroTwo what to change. The same annotation workflow available for code, Markdown files, and websites also works with documents, spreadsheets, and presentations.For example, you can:
  • Select a navigation bar on a website and ask ZeroTwo to change its font.
  • Highlight a claim in an investment thesis and ask for its source.
  • Mark a chart on a slide and request a clearer label.
ZeroTwo uses the selected area as context for your request, so you can refine the file without starting over or changing the parts you already like. Annotations are particularly useful after the first draft, when the work needs review and iteration.
