Which is faster, AI browser sidebars or LocalBridge?

For a single page the difference is small. Across several pages the gap widens quickly, because quick questions about the page in front of you and asking one question across several open pages describe different jobs, not different speeds at the same job.

Yes, and most people do. AI browser sidebars and LocalBridge 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

AI browser sidebars vs LocalBridge

A chat panel built into the browser that can see the page you are on. A Chrome extension that reads the tabs you tick and sends their readable text to Claude or ChatGPT. They overlap enough to feel interchangeable and differ enough that picking wrong costs you an afternoon. Here is what each is actually good at.

AI browser sidebars

A chat panel built into the browser that can see the page you are on.

Strengths

+ No extra install if your browser ships one
+ Tight integration with the current page
+ Often free at low usage

Limits

- Usually limited to the active tab
- You are locked to whichever model the browser chose
- Heavier usage generally moves to a subscription

Best for: Quick questions about the page in front of you.

LocalBridge

A Chrome extension that reads the tabs you tick and sends their readable text to Claude or ChatGPT.

Strengths

+ One click for a whole batch of tabs
+ Keeps the title and URL with each page so answers can be attributed
+ Strips page furniture before sending, which saves context
+ One-time licence rather than a subscription

Limits

- Chrome only today
- Cannot read pages the browser itself blocks, such as settings pages
- Video and image content is not transcribed

Best for: Asking one question across several open pages.

How to choose

Judge them on the job rather than the feature list. AI browser sidebars is the right call when the work looks like: quick questions about the page in front of you. LocalBridge wins when the work looks like: asking one question across several open 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.
