Anthropic ships its own extension, and a crowd of third-party sidebars also route to Claude. They solve different problems, so the right pick depends on whether you want Claude to act on one page or to read several at once.
1 / 4 - Deepest Claude integration on the page in front of you.by Anthropic
The official option, and the only one that can act on a page rather than just read it. Availability has been tied to higher Claude tiers, so check your plan before counting on it.
Good at
- + Deepest possible Claude integration, built by Anthropic
- + Can act on the current page, not just read it
- + No third party sits between you and the model
Watch for
- - Availability has been limited and tied to higher-tier Claude plans
- - Oriented around the active tab rather than a batch of tabs
- - Agentic browsing carries its own risks on pages you are signed in to
by LocalBridge
Does one thing: ticks several tabs and drops their readable text into Claude with titles and URLs attached. No chat of its own, no subscription, no third party in the middle.
Good at
- + Batch: several tabs in a single send
- + Keeps each page's title and URL so answers can be attributed
- + Strips navigation and boilerplate before sending
- + One-time licence rather than a subscription
Watch for
- - Chrome only
- - Does not host the chat: you use your own Claude or ChatGPT account
- - Cannot read browser settings pages or transcribe video
by Sider.ai
A full sidebar with Claude among several models. Convenient if you switch models often, at the cost of a subscription and routing page text through their service.
Good at
- + Switch models without switching tools
- + Page-aware chat and quick actions on selected text
- + Broad feature surface
Watch for
- - Subscription pricing with usage tiers
- - Page content passes through a third-party service
- - Feature breadth can mean a busy interface
by Monica
Broad feature set and shortcuts on every page. Good if you want one assistant everywhere; heavier than you need if you only want context moved.
Good at
- + Wide range of built-in shortcuts
- + Works on most pages without setup
- + Multi-model access from one place
Watch for
- - Free tier is capped; heavier use is paid
- - Broad permissions for broad features
- - Your content is processed by their service
- How was this list of best claude chrome extensions put together?
- Against four stated criteria: Does it work with a normal Claude account, or does it need a higher plan? One page at a time, or a batch of tabs? Who handles the page content: Anthropic, you, or a third party? Is the cost one-time, subscription, or usage-based? Nothing on this page is an affiliate placement.
- How often is it updated?
- Last reviewed 2026-09-15. This space moves quickly, so entries are re-checked rather than left to age, and each tool carries its own review date.
- Is LocalBridge on the list because you make it?
- It is our product, and it is listed for the one job it does better than the alternatives: sending several tabs at once. Where another tool is the better answer, the page says so.
