You can attach files to AI chat messages to give the assistant additional context. Attach a brief, a PDF, a spreadsheet, or any reference document, and the AI will read it before responding.

Adding Attachments

There are two ways to attach a file:

• Paperclip button: Click the paperclip icon in the chat input and pick a file from your device
• Drag and drop: Drop a file directly onto the AI chat panel

You can attach up to 3 files per message. Each attached file shows up as a badge in the input — click the X on a badge to remove that file before sending.

Supported Files

• Documents: PDF, DOCX, TXT, Markdown
• Spreadsheets: XLSX, CSV (with improved spreadsheet handling)
• Images: PNG, JPG, GIF
• Other: most plain text formats

What to Use Attachments For

• Share a project brief and ask the AI to extract key requirements
• Attach competitor research and ask for a comparison
• Drop a spreadsheet of data and ask for analysis or chart suggestions
• Attach a previous version of a doc and ask the AI to update it
• Combine a file with @mention canvas context for more grounded outputs

Tips

• Attach only the files most relevant to a prompt — fewer, more focused attachments give cleaner answers
• For very long PDFs, ask the AI to summarize first, then ask follow-up questions
• Pair attachments with Knowledge entries in AI Settings for project-wide context
