Inline File Preview for Chat Attachments and AI Tool Outputs
May 29th, 2026
You can now preview files directly in chat without downloading them. Click the expand icon on a file attachment or an AI-generated output file to open it in a preview modal.
Preview supports the following file types:
- PDFs
- Markdown
- Syntax-highlighted code and text files (including
.py,.js,.ts,.json,.sql,.yaml,.html,.css,.log, and more) - CSV and TSV tables
- Images
- Video (mp4, webm, ogg)
File types that aren't supported for preview — like Word, Excel, PowerPoint, and archives — continue to work as download-only, unchanged.
