How Workspace Files Work
Every workspace has a shared file library. When you upload a document, RelayHub processes it through the RAG (Retrieval-Augmented Generation) pipeline — extracting text, splitting it into chunks, and generating vector embeddings. Once indexed, the AI can search and reference the file’s contents when answering questions in any workspace conversation.Files uploaded to a workspace are only available within that workspace. They do not appear in your personal file library or in other workspaces.
Supported File Types
RelayHub supports a wide range of document formats:Documents
PDF, Word (.docx), PowerPoint (.pptx), plain text (.txt), Markdown (.md)
Spreadsheets
Excel (.xlsx, .xls), CSV — with full column-aware querying
Images
PNG, JPG, WEBP — analyzed via AI vision for charts, diagrams, and text extraction
Uploading Files
Open the Files tab
Navigate to your workspace and click the Files tab. You will see all currently uploaded files and their processing status.
Upload your documents
Click the Upload button or drag and drop files into the upload area. You can upload multiple files at once.
Wait for processing
Each file goes through a processing pipeline: text extraction, chunking, and embedding generation. You will see a progress indicator for each file. Small documents process in seconds; large PDFs may take a minute or two.
File Processing Pipeline
When a file is uploaded, it passes through several stages:| Stage | Description |
|---|---|
| Upload | File is stored securely in object storage (MinIO). |
| Extraction | Text and tables are extracted from the document. PDFs use OCR when needed. |
| Chunking | The extracted text is split into overlapping chunks optimized for retrieval. |
| Embedding | Each chunk is converted into a vector embedding and stored in the vector database. |
| Ready | The file is fully indexed and available for AI search. |
Reindexing Files
Occasionally you may want to reindex a file — for example, if the processing pipeline has been upgraded or if the original indexing encountered issues. To reindex a file:- Open the Files tab in your workspace.
- Find the file you want to reindex and click the options menu (three dots).
- Select Reindex. The file will be re-processed through the full extraction and embedding pipeline.
Removing Files
Owners, Admins, and Members can remove files from a workspace. Open the Files tab, click the options menu on the target file, and select Remove. This deletes the file from storage and removes all associated embeddings from the vector database.How Files Affect AI Responses
When you send a message in a workspace conversation, the AI performs a semantic search across all indexed files in the workspace. The most relevant chunks are included as context in the AI’s prompt, allowing it to ground its response in your actual documents. This means:- More files, better answers. The more relevant documents you upload, the richer the AI’s context.
- Workspace scoping matters. The AI only searches files in the current workspace, so keep workspaces focused on a specific topic or project for the best results.
- Citations are traceable. When the AI references a document, it indicates the source file so you can verify the information.
