The knowledge base is the document library inside a project. Every file you upload is processed by Saga — the text is extracted, broken into passages, and stored so the AI can find the most relevant parts when you ask a question. This is what makes Saga’s answers grounded in your actual documents rather than general knowledge.

​
Add documents

Drag and drop files or folders directly into the knowledge base panel, or click Upload to browse your computer. If your organization has SharePoint or Epona365 configured, you can import files from those services as well. Saga supports a wide range of file types:
CategoryFormats
DocumentsPDF, DOC, DOCX, TXT, HTML, CSV, ODT
SpreadsheetsXLS, XLSX, ODS
PresentationsPPTX
EmailEML, MSG
ImagesPNG, JPG, JPEG, GIF, WEBP, TIFF
The maximum file size is 1 GB. A project can hold up to 1,000 documents. After upload, each file goes through processing before it’s available to the AI. You can keep working while this happens — documents become available automatically as they’re ready. If a file fails to process, you can retry it from its action menu.

​
Active and inactive documents

Every document has an active/inactive toggle. Only active documents are used as context by the AI. Inactive documents stay in the knowledge base but are excluded from chat and grid review. This is useful when you want to narrow the AI’s focus to a specific subset of files — for example, during a phase of a matter where only certain contracts are relevant.

​
Folders and tags

You can organize documents with folders and color-coded tags. Folders let you replicate your existing file structure. Create nested folders, drag documents between them, and download an entire folder as a ZIP when you need to share files outside Saga. Tags work across folders. Assign a tag to a document, give it a color, and use the tag filter to show only documents with that label. Tags are useful for marking document types, review status, or anything else that cuts across your folder structure.

​
Document actions

Each document has an action menu where you can rename it, move it to a different folder, manage its tags, download it, retry processing, or delete it. You can also select multiple documents at once for bulk download or deletion.
