Upload Files in Chat — Unique AI Documentation

Upload Files in Chat

Upload Files in Chat — Drag and drop or upload files directly into a chat space to query them instantly, without adding them to the broader knowledge base.

Overview

The Upload Files in Chat feature allows users to drag and drop or manually upload files directly into a chat space. Once uploaded, files are ingested by the agent and become queryable within that specific chat — without affecting the broader space context. This enables more contextual, document-specific interactions without the need to upload into the knowledge base.

Who is this for?

This feature is designed for anyone using the chat space who wants to work with files in a lightweight, one-off way. It is especially helpful for users who do not want to upload documents to the broader knowledge base — for example, when dealing with one-time use files, ad hoc requests, or confidential materials that are best kept scoped to a single conversation.

Benefits

Benefit	What it means for you
Chat with documents instantly	Work with files without leaving your chat space — all within a single, focused workspace.
Faster setup	Fewer clicks compared to uploading to the knowledge base or configuring context filters.
Temporary by design	Files can have a configurable expiration date set by your admin, shown on each document link.
Simplifies scoping	Automatically limits document context to the current chat — no cross-chat bleed.
Avoids knowledge base clutter	Keeps one-time or ephemeral files out of the central knowledge base.

Step-by-step guide

Step 1: When "Upload files in chat" is enabled, you will see the following visual above the prompt bar.

Step 2: Upload your file — choose one of two methods:

Drag and drop a file directly into the large area bordered by the dotted line.
Click "Upload Files" — this opens your device's internal file navigation system.

Step 3: Wait for processing — once added, you will see the file processing at the top of your chat.

Step 4: Confirm ingestion — once successfully ingested, the file appears at the top of the chat showing the upload date and expiry date (if applicable).

Step 5: Start chatting — you can now chat against your document.

File retention behaviour

The UI for files uploaded in the chat differs based on whether the file retention period is set or not.

Scenario	What you see
Retention period defined — file active	File appears at the top of the chat showing the upload date and expiry date.
Retention period defined — file expired	File is shown as expired and can no longer be queried. Re-upload to regain access.
No retention period defined	No expiry information is shown. The file will not be automatically deleted.

Tips & tricks

Tip	Details
Avoid protected files	Password-protected or encrypted files cannot always be ingested properly.
Reusable files → knowledge base	If a file will be reused across chats or teams, upload it to the knowledge base instead.
Document-only results	Toggle on the "Check Documents" tool and ensure no folders or documents are selected from the knowledge base for precise, file-only results.
Upload multiple files at once	Highlight and drag multiple files into the chat, or select them together via the file picker.
Plan for retention	Be aware of the retention period to avoid losing important files. Re-upload at any time to regain access.

Limitations

Supported file types only: Extremely large documents, files with heavy media content, or password-protected files may encounter ingestion issues.

Files do not persist indefinitely: Expiration dates may apply based on your workspace configuration.

Scoped to the current chat only: Files are queryable only within the chat they were uploaded to — not accessible across other chats or spaces.

Not part of global context: Uploaded files are not included in the knowledge base context filter or global search.

Expired file edge case: Issues may arise when summarizing documents if all files in a chat have expired.
