Tutorial: Setting Up Your Knowledge Library¶
For full details on adding documents, folder uploads, and traceability, see Knowledge Library.
This tutorial shows you how to upload your reference material so the Co-engineer can use it. Takes about 5 minutes.
Do this first, before anything else. The Co-engineer draws on the Knowledge Library for every task — creating schemas, filling in data documents, answering questions. The richer the library, the better and more traceable its output. An empty library means generic answers; a populated library means answers grounded in your actual project data.
Step 1 — Open the Knowledge Library¶
Click Knowledge Library in the sidebar.

Step 2 — Add your documents¶
Click + Add. A dropdown appears with three options:

- Upload Document — upload a PDF, TXT, or JSON file (a paper, test report, spec, datasheet). This is the most common option.
- Upload Folder — bulk upload many files at once. A progress indicator tracks succeeded and failed files.
- Add Knowledge — type a note directly without a file. Use this for decisions and rationale captured in the moment.
Choose Upload Document, select your file, give it a name and tags, and click Upload. Protos splits it into chunks and embeds them so the Co-engineer can search across the content.
Step 3 — Or let the Co-engineer create knowledge from a conversation¶
Notice the Create with Co-Engineer button at the top. After a Co-engineer session, it can save key findings, decisions, or summaries directly into the Knowledge Library. Any future session can then draw on what was captured.
Step 4 — Tag consistently¶
Pick a tag taxonomy with your team before you start — for example by material (graphite, nmc811) or type (paper, decision, spec). Inconsistent tags make search unreliable later.
Step 5 — Verify it's working¶
Search for a keyword you know is in a document you just uploaded. If it appears, the library is ready.
One thing that matters most: capture decisions as text notes as you make them. A note like "Chose 1.2 mol/L — Q1 study showed peak conductivity at this concentration" written in the moment is far more useful than trying to reconstruct it six months later.
