Stop Highlighting Words You’ll Never See Again – Just use Readwise

I used to watch my students do this constantly. New word shows up in a reading passage, out comes the yellow highlighter, word gets a nice bright rectangle around it, and everyone moves on feeling productive. Ask that same student about the word three weeks later, though, and you get a blank stare, maybe a nervous laugh, sometimes a guess that’s not even close. The highlighting felt like learning. It wasn’t.

I’ll admit my bias up front: I’ve been using Readwise and its reading app, Reader, for a while now, and I’ve become the annoying friend who brings it up unprompted. So take the enthusiasm here with a grain of salt. But I think it solves a problem that almost every serious English learner runs into, and I want to walk you through why.

The problem isn’t reading. It’s forgetting.

Most learners already know they should be reading more English — articles, newsletters, the occasional book chapter. That part isn’t the issue. The issue is what happens after. You hit a word you don’t know, you look it up, you feel a small hit of satisfaction, and then that word evaporates from your memory within a few days. This is just how memory works; it’s called the forgetting curve, and it applies to native speakers learning new vocabulary too, not just ESL students. The fix isn’t reading more. It’s reviewing what you’ve already read, at the right intervals, before your brain lets it go.

That’s the entire premise behind Readwise. It pulls in your highlights — from Kindle books, from articles, from wherever you’re reading — and resurfaces them on a schedule designed to catch you right before you’d forget. Instead of cramming a word list the night before a test, you see the tricky idiom again on day three, again on day nine, again on day twenty-one, until it actually sticks.

Reader is where you build the habit

Reader is the companion app, and it’s genuinely one of the better “read everything in one place” tools I’ve tried. Web articles, email newsletters, RSS feeds, PDFs, EPUBs, even X/Twitter threads — it all lands in a single, clutter-free inbox. You even get a personal forwarding email address, so you can send newsletters straight into Reader and keep your actual inbox from turning into a graveyard of unread English-language content you meant to get to someday.

For a C1 or C2 learner, this matters more than it might sound like at first. You can build an actual reading diet around what you care about — horror fiction blogs, gaming news, true crime write-ups, whatever gets you reading past paragraph two — instead of forcing yourself through some generic “graded reader” that talks to you like you’re eight years old. Highlight as you go: an idiom, a grammar structure, a sentence that just sounds right in a way you couldn’t have written yourself. That’s the raw material everything else runs on.

Ghostreader is the part that changes the math

Here’s what used to kill my own reading momentum when I’m learning a second language: hitting an unfamiliar word, opening a separate dictionary app, translating it, and trying to find my place again in the article. By the time I got back, I’d lost the thread.

Ghostreader, Reader’s built-in AI assistant, removes that entire detour. Select a word or a passage, and it’ll define it, explain it in context, or translate it without you ever leaving the page. It can summarize a dense article before you commit to reading the whole thing, or “x-ray” a specific character or reference in a story so you’re not lost when a comic or a novel assumes cultural knowledge you don’t have yet. And when it answers a question, it links back to the exact line in the text it pulled from — it’s not just guessing at you, it’s showing its work.

There’s a text-to-speech option too, which is worth using more than people expect. Listening to an article while you follow along, then going back to highlight the tricky bits, gets you both the sound and the meaning of new vocabulary in one pass. For a language you’re still training your ear on, that combination matters.

Mastery turns highlights into actual recall

This is the piece most read-it-later apps skip entirely. Once you’ve built up highlights, Readwise’s Mastery feature converts them into two kinds of practice: question-and-answer flashcards, or cloze deletion — meaning the key word gets hidden from a sentence you highlighted, and you have to recall it before it’s revealed. Passively re-reading a highlight teaches you almost nothing. Being forced to produce the missing word yourself is a completely different kind of learning, and it’s the kind that actually transfers to your own speaking and writing.

Every morning, your Daily Review shows up — email or in-app, your choice — with a curated set of past highlights waiting for you. Five minutes, no separate study session to schedule and then skip. Over a few months, that quiet daily habit builds a vocabulary that’s genuinely yours, pulled from things you chose to read, not memorized off a list some textbook editor picked for you.

Here’s the one flaw

There’s no free tier. You get a 30-day trial to test it properly, and after that you’re paying — $9.99 a month if you commit to the year (about $120 total), or $12.99 month to month if you want the flexibility. That’s a real number, and it’s genuinely one of the pricier tools in this category. If you’re the kind of reader who highlights a sentence once a month and calls it a day, I’d save your money; you won’t get enough out of it to justify the cost.

There’s also an onboarding curve. The inbox system, the highlighting shortcuts, the settings — it’s built for people who read as a serious part of their day, and it can feel like more machine than you need if all you want is “save article, find article later.” That’s a fair criticism, and I’d rather tell you that now than have you sign up and feel overwhelmed in week one.

But if you’re actually building an English vocabulary through content you care about — which, if you’re reading this blog, is presumably exactly what you’re doing — that complexity is the price of the system working for you instead of you having to manage it yourself. And here’s the detail that tips it for a lot of my readers: Readwise offers a 50% student and academia discount. If that’s you, email them before you subscribe and ask — it roughly cuts that yearly number in half. And here’s the cool part: If you sign up with our affiliate link, you can try Readwise out for 60 days at no cost.

Try it before you decide anything

Don’t take my word for it. Use the 60-day trial through our link. Pick three articles or newsletters this week, actually related to something you enjoy, and highlight anything — a phrase, an idiom, a sentence structure — that catches your ear. Check your Daily Review tomorrow morning. See if that word is still there for you a week from now.

That’s the whole test. Everything else is just details.
