How to answer questions about a file while browsing with Endoplexity

Attach a PDF or other document and have the agent read it while answering questions about a web page.

Credentials. Contents of an attached file go directly into the model's context, so attach only documents you are willing to share with the model provider.

Who it is forA person reviewing a contract, statement, or report who needs to check a web page against a document they already have on disk.

The problemCross-checking a page against a long attached file means scrolling back and forth and reading both carefully.

The outcomeAnswers that draw on the attached document's text, with the agent able to report when a file type cannot be read.

What you need first

  • Node 24 or newer, checked with `node -v`
  • Chrome 114 or newer
  • The claude CLI, the cursor-agent CLI, or both, already logged in to a subscription (Claude Pro is enough)
  • Git, to clone the repository

Steps

  1. Run npm start in the Endoplexity folder, and keep the terminal open so you can watch its log.
  2. Load the extension/ folder in Chrome and open the web page you want to check.
  3. Drag the document onto the side panel composer so it appears as a chip.
  4. Type your question, asking the agent to use the attached file, and press Run.
  5. Use the × on the file chip to delete the bridge's copy when you are finished.

Prompt for your agent

Using the Endoplexity repo at <repo path>, read the attached file <file name> with read_file and compare its terms against the open page at <page URL>. Return each point of disagreement with the file section and the page text it refers to. Verify that every quoted passage appears in the file or the page.

Caveat. Attachments are read as text, and files that cannot be converted to text are reported as such rather than guessed at.
