Evidence Collections let you build named libraries of reference material — PDFs, guideline documents, links to trusted sources — that Vero can draw from when you ask a clinical question. Instead of pasting the same paper or guideline into every query, save it to a collection once and have Vero reference it automatically going forward.
What you can put in a collection
Documents — PDFs, Word documents, plain text. Useful for clinical practice guidelines, internal protocols, drug monographs, consensus statements, or any reference you refer back to often.
Sources — links to web pages. Useful for open guideline sites, journal articles, or organizational policy pages.
Once an item is added, Vero extracts the text, chunks it, and indexes it so future questions can pull the most relevant passages with citations back to the original.
Creating a collection
Open the Library dialog.
Click New Collection, give it a name (e.g. "Cardiology Guidelines"), and an optional description.
Add items:
Drag and drop a PDF or Word file into the collection.
Paste a URL to add a web source.
Items appear with a processing indicator while Vero extracts and indexes the content. Most documents finish in under a minute; long PDFs may take a few minutes.
Once an item shows Ready, it's available to Vero.
Using a collection when you ask a question
When you open the Library dialog from Vero Chat or Vero Evidence, select the collections you want to include in your next query. Vero will prioritize passages from those collections as it answers, and cite specific documents inline so you can trace any claim back to its source.
Sharing with your team
If you're part of a clinic or organization on Vero, you can share a collection with the whole team:
Open the collection.
Click the Share icon.
The collection becomes visible to everyone in your organization. Shared collections show a Share icon in the library grid so you can tell them apart from personal ones.
Unsharing is just as fast — click Share again to make the collection private to you. Any team member who had it loaded will see it removed from their library on next refresh.
Sharing is organization-wide. There is no per-user or read-only sharing at this time — sharing opens the collection to every member of your organization.
Renaming, updating, and deleting
Rename a collection — open the collection and edit the name inline.
Remove an item — delete a single document or source without touching the rest of the collection.
Delete a collection — removes the collection entirely. Documents that belonged only to this collection are deleted from storage; documents that are also in another collection are preserved.
Tips
Name collections by topic, not by document. "Canadian Diabetes Guidelines" is easier to scan than "CDA 2023 CPG Main Document.pdf".
Keep one collection per workflow. A single "Everything" collection is harder to reason about than a few focused ones — Vero will still pull from all of them when you include them in a query.
Update when guidelines change. Remove the old PDF and add the new one. Vero uses whatever is currently in the collection — there's no version history.
Share your most-used reference for the team once. Sharing a collection with your organization saves every colleague from having to upload the same PDFs themselves.
Common Questions
Is there a limit to how many items I can add? No hard limit today. Very large documents take longer to process but will still be indexed.
What file types are supported? PDFs, Word documents, and plain-text files for documents; any public URL for sources.
Is content from collections used to train AI? No. Documents you upload to your collections are used only to answer your own (and your team's) questions — never for model training. See our Privacy & Security article for details.
Can I share a single collection with just one colleague? Not currently — sharing is all-or-nothing at the organization level.
Can I see which documents a particular answer came from? Yes — Vero Evidence shows inline citations that link back to the source document or URL in your collection.
