How to Highlight Text on Any Website (and Actually Keep It)

To highlight text on any website, install a web highlighter extension like Marqly: select the text, pick a color from the small toolbar that appears, and the highlight persists — on the page when you come back, and in a searchable library alongside every other highlight and bookmark you’ve saved.

That’s the whole technique. The hard part was never making a highlight — it’s keeping it somewhere you’ll actually see it again. This guide covers why bookmarks can’t do that job, why the common workarounds quietly fail, and how to set up highlighting that survives reloads, revisits, and the passage of six months.

Why isn’t bookmarking the page enough?

Because the way you remember a page is a sentence, not a URL. Browser bookmarks save pages; the thing you wanted to keep was a passage. A bookmark points at 4,000 words of article when what stopped you mid-scroll was one paragraph — a statistic, a definition, a line you knew you’d want to quote later.

So the bookmark “works,” in the sense that the page opens. Then you’re skimming the whole thing, hunting for the line you already found once. Do that a few times and you stop trusting your saved links entirely. It’s the same failure mode as trying to find a saved article when you’ve forgotten the title: the tool stored the container, but your memory works at the level of the contents.

Highlighting fixes the resolution problem. It saves at the level you actually think at — the sentence — and a good highlighter keeps that sentence attached to its source, its context, and the exact spot on the page where you found it.

What do people use instead of a highlighter — and why does it fail?

The three common workarounds — pasting into notes apps, screenshots, and printing to PDF — all lose something you’ll want later: the source, the searchability, or the living page. Each one feels fine in the moment. The cost shows up weeks later, at retrieval time.

Copy-paste into a notes app. You select the passage, switch to Apple Notes or Notion, paste, maybe remember to paste the URL too. The quote survives, but it’s stranded: no link back to the exact paragraph, no surrounding argument, no idea six months later whether the author said it or was quoting someone else. And because every capture costs an app-switch, you do it less and less until you stop.

Screenshots. Fast, which is why everyone does it. But a screenshot is a picture of text, not text — you can’t search it, can’t copy from it, and it lands in a camera roll between a parking receipt and a group-chat meme. There’s no route back to the page, and no way to tell which part of the screenshot mattered.

Printing to PDF. The strongest of the three for one job: archiving. If you think a page might change or disappear, saving it as a PDF is exactly right. But as a highlighting workflow, it freezes the page — your markup lives in a file on disk, detached from the live URL. Next time you land on that article from a link or a search, your annotations aren’t there.

Method	Keeps source + context	Searchable text	Visible on the page later	Effort per capture
Copy-paste into notes	❌ Link and context usually lost	✅ Text, but detached from the page	❌ No	High — switch apps every time
Screenshots	❌ No route back to the page	❌ It’s an image	❌ No	Low, but piles up unsearchably
Web highlighter	✅ Anchored to the exact passage	✅ Text plus your notes	✅ Restored on revisit	Lowest — select, pick a color

What should a good web highlighter actually do?

Five things are non-negotiable: highlights that persist on revisit, multiple colors, attachable notes, one searchable home, and click-to-jump back to the passage. Miss any one and the tool degrades into a prettier version of the workarounds above.

1. Persist on revisit. Reload the page, come back a month later — the highlight should be sitting exactly where you made it. If highlights only live in a separate app, you’ve built copy-paste with extra steps.
2. Multiple colors. One color means “something here mattered.” Several colors let the highlight say what kind of thing mattered — evidence versus counterargument versus a quote you’ll reuse.
3. Notes. The passage is what the author said; the note is why you cared. Future-you needs both, and the note is the half that evaporates fastest from memory.
4. One searchable home. Highlights scattered across pages are only useful if they also roll up into a single library you can search — ideally the same library as your bookmarks, so links and passages live together.
5. Click-to-jump. Retrieval should end on the page, not in a list. Clicking a highlight in your library should scroll the original page straight to the passage, context intact.

There’s a quick way to test any highlighter against this list: highlight a passage, close the tab, and come back tomorrow through a fresh search. If the highlight is waiting on the page and you can also reach it from a library view, the tool passes. If either half is missing, you’ll feel it within a month.

How do you highlight text on any website with Marqly?

Install the extension, select text, pick a color — Marqly handles the persistence, the syncing, and the library. Here’s the full loop:

1. Install the Marqly extension. It’s free to install and works on Chrome, Edge, Firefox, and Safari.
2. Select text on any web page. A small toolbar appears next to your selection.
3. Pick one of six highlight colors. The highlight is applied on the page instantly. Optionally, attach a note — a line about why this passage matters.
4. Reload or revisit whenever. Your highlights are restored right on the page, exactly where you made them. Nothing to re-open, nothing to cross-reference.
5. Open the side panel to review. The browser side panel lists every highlight on the current page and across your whole library. Click any highlight and the page scrolls to it.
6. Find everything later in the web app. Highlights sync to your Marqly account and appear alongside your bookmarks — one searchable library of links and passages instead of two disconnected piles.

On pricing, plainly: highlights and notes are part of Marqly Pro, which is $48/year — about $4 a month, billed annually — with a 7-day free trial. The extension itself is free to install, and the free features (bookmarking, tab saving) stand on their own. Try the highlighter on a real research session during the trial; a week is enough to know whether persistent highlights change how you read.

How do highlights become a research workflow?

Once highlights persist and pool in one library, they stop being decoration and start being a second brain you built by accident — just by reading. Three habits make it compound:

Use colors as meaning. With six colors available, assign a few of them jobs: one for core claims, one for evidence and numbers, one for counterarguments, one for lines worth quoting. Now a glance at any revisited page shows you the shape of what you found — and your library becomes skimmable by kind, not just by topic.

Use notes as “why it matters.” A highlight captures the author’s words; a one-line note captures your reaction — “contradicts the pricing post,” “use in Q3 deck.” That’s the connective tissue most systems lose. It’s the same low-maintenance principle behind building a second brain that doesn’t collapse: capture cheaply in the moment, so the system still exists in six months.

Let one library do the finding. Because highlights sit next to your bookmarks, one search covers both the links you saved and the passages you marked. Pair that with AI search across your bookmarks and retrieval stops depending on remembering titles or filing anything — which is the entire point of a second-brain app.

Share the output, not a link dump. When the research is for someone else — a team, a client, readers — make the board public. It’s explicit consent, never a default; Marqly then generates a public page of that board’s links and highlights that anyone can view without signing up. Instead of pasting ten URLs into Slack, you hand over the reading and the marked-up conclusions in one page.

Keep what you read, not just where you read it

Bookmarks answer “where was that page?” Highlights answer the question you actually ask: “where was that line?” The setup takes two minutes — install the Marqly extension (free, on Chrome, Edge, Firefox, and Safari), highlight a passage on the next article you read, then reload the page and watch it come back. Highlights and notes come with a 7-day Pro trial — no commitment, and the bookmarking stays free either way.
