Which is faster, Manual copy and paste or Downloading and uploading files?

For a single page the difference is small. Across several pages the gap widens quickly, because one page, once and documents that already exist as files rather than as pages describe different jobs, not different speeds at the same job.

Yes, and most people do. Manual copy and paste and Downloading and uploading files fail in different places, so keeping both available costs nothing and covers the cases the other one misses.

Which is better for pages behind a login?

Anything that reads the page as your browser already renders it works on signed-in pages. Anything that asks the assistant to fetch a URL itself does not, because it arrives without your session.

Which one preserves the source of each claim?

Only approaches that carry the page title and URL alongside the text. Without them the assistant can summarise but cannot attribute, and you lose the ability to check an answer.

Comparison

Manual copy and paste vs Downloading and uploading files

Selecting text on a page, copying it, switching tabs and pasting it into a chat. Saving pages as PDFs or documents and attaching them to the chat. They overlap enough to feel interchangeable and differ enough that picking wrong costs you an afternoon. Here is what each is actually good at.

Manual copy and paste

Selecting text on a page, copying it, switching tabs and pasting it into a chat.

Strengths

+ Works everywhere with no install and no cost
+ You see exactly what is being sent
+ No permissions to grant to anyone

Limits

- Slow, and the cost scales with the number of tabs
- Selection usually drags in navigation and footer text
- Source titles and URLs are lost unless you type them

Best for: One page, once.

Downloading and uploading files

Saving pages as PDFs or documents and attaching them to the chat.

Strengths

+ Handles real PDFs, including ones no extension can read from the page
+ Attachments persist in the conversation for later questions
+ No extra software beyond the browser and the assistant

Limits

- Save, find, attach: several steps per document
- Web pages printed to PDF keep the navigation and page furniture
- Upload limits on file count and size apply on most plans

Best for: Documents that already exist as files rather than as pages.

How to choose

Judge them on the job rather than the feature list. Manual copy and paste is the right call when the work looks like: one page, once. Downloading and uploading files wins when the work looks like: documents that already exist as files rather than as pages.

The failure modes matter more than the strengths, because that is where the afternoon goes. Check the limits column against your own pages, particularly anything behind a login, anything paywalled and anything rendered as an image.
