Which is faster, Manual copy and paste or Screenshot upload?

For a single page the difference is small. Across several pages the gap widens quickly, because one page, once and visual content where layout is the point describe different jobs, not different speeds at the same job.

Yes, and most people do. Manual copy and paste and Screenshot upload 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 Screenshot upload

Selecting text on a page, copying it, switching tabs and pasting it into a chat. Capturing the screen as an image and attaching it 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.

Screenshot upload

Capturing the screen as an image and attaching it to the chat.

Strengths

+ Captures anything visible, including charts and layout
+ Works with tools that block text selection
+ No extraction step to go wrong

Limits

- Only the visible viewport is captured
- Text has to be read back out of the image, which is lossy
- Images consume far more context than the same text

Best for: Visual content where layout is the point.

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. Screenshot upload wins when the work looks like: visual content where layout is the point.

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.
