How to Capture Your First Article

A practical, step-by-step guide to capturing your first article into Project Nexus.

What You Need​

  • Extension installed and loaded in Chrome (see Installation).
  • At least one BYOK API key configured (see BYOK Setup).
  • The extension connected to your account (via the Sign In button in the popup).

Steps​

1. Find an Article to Capture​

Open any article page — a blog post, a news article, documentation, or a research paper. The extension works best on pages where the main content is wrapped in an <article> HTML element.

2. Open the Extension Popup​

Click the Nexus icon in your Chrome toolbar. You will see:

  • Your daily capture count.
  • A Capture button.
  • A short history of your recent captures.

3. Click "Capture"​

Click the Capture button. The popup status indicator will cycle through:

  1. Extracting content… — scraping the article text from the DOM.
  2. Processing with AI… — calling your LLM API to generate a summary and extract entities.
  3. Saving to database… — storing the node and creating vector-similarity edges.
  4. Done! ✅ — The capture is complete.

4. View in the Dashboard​

Open the Project Nexus dashboard (http://localhost:3000/dashboard). Your article appears at the top of the Feed with:

  • The page title.
  • An AI-generated summary.
  • Entity tags (people, tools, concepts).
  • Timestamp.
