Supported formats and limits

Supported file types

Size limit

Maximum file size: 50MB per file.

Text sources

You can also add Knowledge by pasting or typing text directly — no file required. These count as sources you author, the same as uploaded files.

Open Library (optional)

When enabled for your Space, you can add public-domain books from Project Gutenberg via Open Library. This is an explicit, optional source — not automatic web access.

Built-in editor

Create documents inside Spaces with the built-in editor. These count as Knowledge sources like uploaded files.
