Leave your thoughts on any website.

Mark up the web.

Highlight anything.
Select text on any website and highlight it through Fabric's browser extension. Your highlights are saved permanently, so you can return to any page and see exactly what you marked, even months later.

Leave notes anchored to content.
Add comments attached to specific text passages, images, or locations on a page. Your notes stay anchored to the exact element you annotated, so they always appear in the right context.

Works on any website.
Annotate articles, documentation, research papers, competitor pages, product listings, or any other web content. If you can view it in your browser, you can annotate it.

Share and discuss.

Collaborative annotations.
Share your annotated pages with teammates, clients, or collaborators. They can see your highlights and comments in context, right on the page where you left them.

Reply and discuss.
Annotations support threaded replies. Start a conversation about a specific passage or image directly on the web page, without switching to email or a messaging app.

Persistent across visits.
Your annotations are stored in Fabric and displayed whenever you return to the page. They do not disappear when you close the tab. Come back days or weeks later and everything is exactly where you left it.

Your browser becomes a research tool.

Web browsing and research often feel like separate activities. You read something interesting, switch to a note-taking app, write down what you found, and try to remember where you saw it. By the time you need the information again, the connection between your notes and the original source is lost. Annotating the web directly solves this by keeping your thoughts attached to the content they refer to.

When you highlight a passage on a web page and add a note, that annotation lives in two places at once. It appears on the web page whenever you revisit it, and it is saved in your Fabric workspace where it is searchable and accessible to your AI assistant. This means your web research produces artefacts you can actually use later. Highlights and comments from a morning of browsing become a searchable trail of everything you found important, with full context about where each insight came from.

Research without leaving the page.

For researchers and students, web annotations turn casual reading into structured research. You can work through a series of articles, highlighting key passages and leaving comments as you go, without switching between your browser and a separate note-taking tool. When you are ready to write, your annotations are waiting in Fabric, organized and searchable. You can review everything you highlighted across dozens of pages, ask your AI assistant to summarize your annotations on a particular topic, or pull your highlights into a note as a starting point for your own writing.

This workflow is especially useful for literature reviews, competitive research, and market research, where you need to process many web sources and synthesize what you find. Instead of copying quotes into a document and losing track of where they came from, your annotations maintain a permanent link back to the original source.

Team annotations for shared context.

Web annotations become even more valuable when shared. A product manager can annotate a competitor's website and share those annotations with the team for discussion. A designer can highlight specific elements on a reference site and explain what they like or want to adapt. A user researcher can annotate documentation or product pages as part of a competitive analysis and share the annotated view with stakeholders. In each case, the conversation happens in context, right on the page, rather than in a separate document where the connection to the original content is lost.

For agencies and consultancies doing client work, shared web annotations offer a way to provide feedback on live websites, review online content together, and discuss web-based materials without taking screenshots and pasting them into a presentation. The annotations are persistent and threaded, so the discussion stays organized and anchored to the content it refers to.

Everything feeds back into your workspace.

Web annotations are not isolated in your browser. They are saved in your Fabric workspace where they join your notes, files, saved articles, and other content. This means your annotations are searchable alongside everything else. A search for a specific topic can return highlights you made on web pages, notes you wrote in Fabric, articles you clipped, and documents in your files. Your web browsing activity becomes part of your broader knowledge base rather than something that disappears when you close the tab.

Annotations are also automatically organized by Fabric's AI. The content you highlight and the comments you leave are indexed and categorized, making them discoverable even if you do not remember which website you were on when you made them.
