Upload files and images
You can attach files to any message you send Dash, whether in Slack, Teams, on the web, or from the Chrome extension. Dash reads the content and uses it as context for your request.
What Dash can read
Section titled “What Dash can read”- Images (PNG, JPG, GIF, WebP) — Dash sees the image and can describe it, extract text, answer questions about what’s in it, or use it as reference for a task.

- Spreadsheets (XLSX, CSV) — Dash reads the data and can analyze, filter, chart, or summarize it.
