Uploading File Attachments

Quick Answer

Click the paperclip / attach button in the chat composer to upload images, PDFs, text files, audio, or video that the AI assistant can analyze alongside your question.

Supported File Types

Type	Examples	Use Case	Model Support
Images	.jpg, .png, .gif, .webp	Screenshots, maps, photos	All models except the text-only default
Documents	.pdf	Reports, presentations	All models except the text-only default
Text	.txt, .csv and other text-based files	Data files, notes	All chat models (incl. the default)
Audio	.mp3, .wav, .m4a	Voice recordings	Gemini 3.1 Pro and Gemini 3.5 Flash
Video	.mp4, .mov, .webm	Screen recordings, clips	Gemini 3.1 Pro and Gemini 3.5 Flash

Note: The default model (Zeus.ai Secure (Third-Party)) is text-only — every other model (Claude, GPT, Gemini) accepts images and PDFs. To attach an image or PDF, first pick one of those from the model selector in the composer. If the active model can't use a file you choose, it's rejected after selection (with a notice), not blocked at the attach button.

Current default limits: Maximum 20MB per file, up to 10 files attached at once in the composer.

Step 4: Send

1. Click Send or press Enter
2. Wait for the file chip / preview row to finish processing
3. The assistant will respond with analysis

Tips for File Attachments

For Images

• Screenshots: Great for asking "What am I looking at?"
• Maps: Share location visuals for context
• Charts: Ask for interpretation or explanation

For PDFs

• Keep files under 20MB for the current upload limit
• Multi-page documents may take longer to process
• Ask specific questions about the content

For Data Files

• CSV files can be analyzed for patterns
• Include context about what the data represents
• Ask specific questions about the data

Use Cases

"What's in this screenshot?"

Upload a screenshot of Zeus.ai and ask:

• "What does this metric mean?"
• "How do I get to this screen?"
• "What should I do next?"

"Analyze this report"

Upload a PDF report and ask:

• "Summarize the key findings"
• "What locations are mentioned?"
• "What are the recommendations?"

"Help me understand this data"

Upload a CSV and ask:

• "What patterns do you see?"
• "Which locations have the highest values?"
• "Create a summary of this data"

Limitations

• File size: Maximum 20MB per file in the current upload control
• File count: Maximum 10 files attached at once in the current upload control
• Processing time: Large files take longer
• Some formats: Specialized formats (e.g., .docx, .xlsx) may not be fully supported
• Default model is text-only: Zeus.ai Secure (Third-Party) (the default) does not support image or PDF uploads. Switch to a Claude or GPT model if you need to attach images or PDFs.
• Model dependent: Audio and video support currently appear on Gemini 3.1 Pro and Gemini 3.5 Flash

Removing Attachments

To remove an attached file before sending:

1. Look for the attached file chip / preview row in the composer
2. Click the ✕ or remove button on the file
3. The file will be removed from your message

Troubleshooting

File Won't Upload

• Check file size (must be under limit)
• Verify file type is supported
• Try a different browser
• Check internet connection

File Not Being Analyzed

• Add a clear question about the file
• Don't just attach—tell the assistant what you want
• Try a simpler question first
