Which is faster, Screenshot upload or Pasting URLs into the chat?

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

Yes, and most people do. Screenshot upload and Pasting URLs into the chat 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

Screenshot upload vs Pasting URLs into the chat

Capturing the screen as an image and attaching it to the chat. Giving the assistant links and asking it to fetch them itself. They overlap enough to feel interchangeable and differ enough that picking wrong costs you an afternoon. Here is what each is actually good at.

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.

Pasting URLs into the chat

Giving the assistant links and asking it to fetch them itself.

Strengths

+ Nothing to install and very little typing
+ The assistant may fetch a live, current version
+ The links stay visible in the transcript

Limits

- Fetching fails on anything behind a login or paywall
- Not every assistant or plan can browse
- You cannot tell what was actually read

Best for: Public pages, when browsing is available.

How to choose

Judge them on the job rather than the feature list. Screenshot upload is the right call when the work looks like: visual content where layout is the point. Pasting URLs into the chat wins when the work looks like: public pages, when browsing is available.

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.
