Open a page, clip what matters, and file it where future-you can find it in seconds. With Diigo, the everyday workflow starts in the browser: highlight text on articles and PDFs, add inline notes, and save the page with a couple of tags that match how you think. Drop new finds into a list for the current project, or send them straight into an outline if you already know where they fit. Use the extension to capture a clean snapshot, keep the original link, or both—so you can revisit the source or rely on your archived copy when pages change.

When you’re ready to turn scattered sources into a plan, switch to an outline. Create top-level sections for questions, arguments, or tasks. Drag saved items into place, nest subpoints, and attach your notes under each heading. Rearranging ideas is fast—pull a card up to promote it, or indent to turn it into supporting evidence. Add quick summaries below each link to capture why it’s included. As the structure settles, you’ve got a working skeleton for a report, video script, lesson, or product brief. Need something you saved last month? Filter by tag, list, or highlight text and drop it right where it belongs.

Sharing is straightforward and controlled. Turn a list or outline into a view-only page for clients or classmates, or invite collaborators to annotate alongside you. Teammates can highlight in different colors, comment on specific passages, and flag duplicates. Lock critical sections, keep drafts private, and publish only when your structure is solid. When it’s time to hand off, export links with notes for import into your document editor, or ship a clean outline that reads like a table of contents with citations.

Build small habits around it. Students triage readings during lecture, tagging by course and week; later, they batch-review highlights and convert them into study outlines. Marketers collect competitor pages and customer quotes, then turn those snippets into a campaign outline with proof points. Developers keep a living library of code examples, docs, and troubleshooting threads, grouped by language or framework. Teachers assemble lesson materials, add guiding questions as notes, and share a curated list with the class. Whether you clear your reading queue at night or clip on the go from mobile, Diigo keeps the flow consistent: capture fast, tag once, structure later, deliver with confidence.
