A Source is anything you’re thinking about: a PDF report, an article you clipped from the web, an image, a video, a meeting document. Sources give your ideas context — every thought or note can point back to the material that sparked it, so you (and later, your teammates) always know where an idea came from.

​
What you can add as a source

Documents

PDFs, Word documents, text and Markdown files, CSVs, and more. Upload them directly or attach them to a thought as you capture it.

Web pages

Clip articles and pages from your browser with the PeerNotes extension. The page’s content and URL are saved together.

Images

Screenshots, diagrams, whiteboard photos — anything visual you want to keep alongside your thinking.

Videos

Upload video files to reference recordings, talks, or demos in your notes.

​
Add a source

There are three ways to get material into your sources library:
1

Upload from the Sources feed

Open Sources in the sidebar and upload a file. Give it a name, and PeerNotes detects whether it’s a document, image, or video automatically.
2

Attach while capturing a thought

In the thought capture box, type or use the attach button. You can upload a new file, paste a link, or search your existing sources and attach one — without leaving the capture flow.
3

Clip from the web

Use the browser extension to save the page you’re reading straight into your workspace, highlights included.

​
Reading and taking notes on sources

Open any source from the Sources feed — or from a source chip on a thought — to read it in the built-in viewer. As you read, capture thoughts about it; each one stays linked to the source, building a trail from raw material to your own thinking.
This is the heart of the PeerNotes reading workflow: read a source, react in thoughts, compile thoughts into a note. When your note cites its sources, teammates reviewing it can check the original material rather than taking your word for it.

​
Sources and your team

Like thoughts, your sources are private raw material by default. What you share is the thinking you build on top of them — but when a shared note references a source, workspace members reading the note can open that source for context.
