Which is faster, Browser reading mode or Custom scripts and automations?

For a single page the difference is small. Across several pages the gap widens quickly, because reading, not asking and repeatable pipelines, not ad-hoc questions describe different jobs, not different speeds at the same job.

Yes, and most people do. Browser reading mode and Custom scripts and automations 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

Browser reading mode vs Custom scripts and automations

The built-in reader view that strips a page down to its article text. Your own scraper or automation that collects pages and calls an AI API. They overlap enough to feel interchangeable and differ enough that picking wrong costs you an afternoon. Here is what each is actually good at.

Browser reading mode

The built-in reader view that strips a page down to its article text.

Strengths

+ Built in and free
+ Excellent at isolating article text
+ No permissions or accounts

Limits

- Only one page at a time
- Does nothing to move the text anywhere
- Unavailable on pages it does not recognise as articles

Best for: Reading, not asking.

Custom scripts and automations

Your own scraper or automation that collects pages and calls an AI API.

Strengths

+ Complete control over extraction and formatting
+ Can run on a schedule without you
+ Fits any pipeline you already have

Limits

- You build and maintain it
- Logged-in pages need credential handling you have to secure
- API usage is metered and adds up

Best for: Repeatable pipelines, not ad-hoc questions.

How to choose

Judge them on the job rather than the feature list. Browser reading mode is the right call when the work looks like: reading, not asking. Custom scripts and automations wins when the work looks like: repeatable pipelines, not ad-hoc questions.

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.
