Knowledge Base
Last updated: October 21, 2026
The Knowledge Base is an initiative's library of source material for creating AI content. Upload your documents, recordings and videos once, then use them to create podcasts, video slides, scripted videos and Power Reads in that initiative. Open it from Knowledge Base in the initiative menu.
Each initiative has its own Knowledge Base. Files in one initiative are not available in another.
Who can use it
Role | Access |
|---|---|
Org Admin, Initiative Owner, Initiative Editor, Content Creator | View, download, upload, rename, delete, and create AI content |
Viewer | View and download |
Content Approver, Topic Content Creator | No access |
Uploading files
Choose Upload, or drag files anywhere on the page. You can add several files at once.
Supported files and size limits:
Type | Formats | Maximum size per file |
|---|---|---|
Documents | PDF, DOCX, DOC, PPTX, ODT, ODP | 200 MB |
Audio | MP3, WAV, OGG, M4A, AAC, FLAC, OPUS | 1 GB |
Video | MP4, MOV, AVI, MKV, WEBM, WMV, FLV, M4V | 3 GB |
For best results, convert PowerPoint files to PDF before uploading.
Stay on the page until uploads finish. Files that haven't finished uploading when you leave might not be added. Files with an unsupported type or over the size limit are listed after you drop them, and are not added.
Your organization's upload policy message appears beneath the page description as a reminder of what can be uploaded. See Upload policy message.
File status
After upload, each file is processed before it can be used.
Processing — the file is being prepared. This continues in the background, so you can leave the page.
Ready — the file can be used to create AI content.
Processing Failed — the file can't be used. Upload it again, or replace it if it is damaged.
Finding files
Search by file name, or filter by File Type, Uploaded By and Uploaded Between. Sort by name, upload date or size. The newest files are shown first.
Creating AI content from files
Select one or more Ready files, then choose Create AI Content. To use a single file, you can also choose Create from its menu.
Pick a content type: Podcast, Video Slides, Scripted Video or Power Read. Scripted Video appears only when it is switched on for your organization.
The creation screen opens with your files already added under Source Materials.
You can also start from the creation screen. In Source Materials, open the Knowledge Base tab and choose Browse Knowledge Base to add Ready files.
How many files you can add depends on the context capacity shown in Source Materials. If a file doesn't fit, remove another to make room.
Files uploaded directly in Source Materials are used only for that piece of content. They are not added to the Knowledge Base.
Managing files
From a file's menu you can Download, Rename or Delete it. Select several files to download or delete them together.
Renaming changes only the name, not the file extension. Names cannot contain slashes, backslashes or control characters.
Deleting permanently removes the file from the Knowledge Base. Content already created from it is not affected.
Two behaviors worth knowing
Files are shared across the initiative. Anyone with manage access can rename or delete any file, not only their own. If a file you selected is removed or changed by someone else before you create content, you are asked to choose a different file.
Only Ready files can be used. If a selected file is still processing or failed to process, AI content can't be created from the selection until you remove it.
