Uploading & Working with Files in ThreoAI

Overview

ThreoAI lets you attach files directly to your conversations. Once uploaded, the AI can read, analyze, summarize, and answer questions about the content. This works with documents, images, spreadsheets, and more.

Uploading a File

1. Open a chat or start a new one
2. Click the ➕ button in the chat input bar
3. Select 📎 Attach files
4. Choose one or more files from your device
5. The file appears as an attachment above the input bar — add your message and press Enter to send

The AI will process the file as part of your message. You can ask it to summarize the content, extract specific information, answer questions, compare documents, or analyze data.

Supported File Types

ThreoAI supports a wide range of common file formats, including:

• Documents: PDF, DOCX, TXT, PPTX
• Images: PNG, JPG, JPEG, GIF, WEBP
• Spreadsheets: XLSX, CSV

File size limits are set by your organization’s configuration. If a file fails to upload, try splitting it into smaller parts or contact your administrator.

Previewing Documents in Chat

After uploading a file, the AI’s response may include a summary or extracted content. To review the original file:

• Click the attachment thumbnail or file name in the chat to open a preview
• PDF files render inline in the chat window, allowing you to scroll through pages without leaving ThreoAI
• Images are displayed inline in the conversation

---

Downloading Files

Files shared in a conversation — either by you or generated by the AI (such as code files or formatted outputs) — can be downloaded directly from the chat:

1. Locate the file attachment or AI-generated file in the conversation
2. Click the download icon or the file name
3. The file saves to your device’s default downloads folder

Tips for Working with Files

• Be specific in your prompt. Instead of “analyze this file,” try “summarize the key findings in this report” or “extract all line items and their costs from this invoice.”
• Multiple files. You can attach more than one file to a single message to compare documents or cross-reference content.
• Large documents. For very long documents, ask the AI to focus on specific sections: “What does section 3 say about refund policies?”
• Images. ThreoAI can describe, analyze, and extract text from images. Ask “What does this screenshot show?” or “Transcribe the text in this image.”

Files in Custom GPTs

When building a Custom GPT, you can upload Training Documents (PDFs, DOCXs, TXTs) that become part of the GPT’s persistent knowledge base — not just a one-off attachment. See Creating a Custom GPT for details.
