Tap the paperclip or drag files into the composer. Aura reads PDFs, Word documents, spreadsheets, slides and images.

## Ideas to try

* *"Summarize this contract and flag anything unusual."*
* *"What's in this photo, and what's the brand?"*
* *"Compare these two proposals in a table."*

## Analyze data

<Frame>

</Frame>

Upload a spreadsheet and ask for totals, trends or charts. Name the output format you need — for example Excel, CSV or PDF — and ask for the completed file. Your original source is not replaced by the generated result. See [Tasks, files and results](/work-mode/tasks-and-results) for larger analysis and multi-step Work Mode jobs.
