An illustration of adding knowledge to a Library, using fictional data.
What you can do
Four ways in, one consistent record.
Web pages
Import a URL and Prism extracts readable full text, keeping the canonical link so citations resolve later.
Notes and excerpts
Paste text directly when the thing worth keeping is a paragraph, not a document.
Video transcripts
Preview a YouTube transcript before you commit, then import it as a first-class transcript source.
Bulk URL import
Paste a list of links and bring in a whole reading queue in one pass instead of one at a time.
Typed on arrival
Each source lands with a fixed type and your reusable tags, so retrieval can be narrowed instead of guessed.
Sources beyond your plan's semantic index cap still import successfully — their metadata and text stay searchable while semantic indexing is paused.
Whole queues, not single links
Bring in a reading list in one pass.
Paste a block of URLs and Prism extracts each one, reports what succeeded, and files everything into the Library you chose. Failures are surfaced rather than silently dropped.
- One URL per line, no separate CSV or import template.
- Extraction handles pages that need rendering, not just static HTML.
- Every imported page keeps its canonical URL.
Import from a URL list
Paste one URL per line

Provenance kept
Every source stays traceable.
Prism stores extracted text next to the original reference. When an AI client cites a passage months later, the path from the claim back to the page it came from is still intact.
- Original URLs, file names, and import dates are retained.
- Text is chunked and embedded for retrieval, never in place of the source.
- Indexing state is visible per source in Knowledge Health.

Full text is stored alongside the original reference, so a citation can always be traced back to the passage it came from — and to the page that passage was taken from.
