5 Tools to Improve Vocabulary (That Aren't Just Boring Flashcards)

Search for "tools to improve vocabulary" and Google will feed you the exact same list of ten flashcard apps. Quizlet. Anki. Memrise. Brainscape.

Don't get me wrong. I respect the math behind spaced repetition. But treating your brain like a poorly optimized SQL database is exhausting.

If you genuinely want to expand your vocabulary—whether for learning English, passing the GRE, or just sounding slightly more articulate at dinner parties—you need tools that integrate with your actual life. Here are five unconventional tools that do exactly that.

1. Toucan (The "Change The Language" approach)

Toucan is a browser extension that randomly translates words on the page you're reading into the language you're trying to learn. So if you're reading an article in English about cooking, suddenly the word "apple" is swapped out for "manzana".

Why it's good: It forces immersion. You are reading English context, but getting hit with Spanish vocabulary. Your brain bridges the gap naturally.

The catch: Sometimes the translations completely butcher the grammar of the sentence. It also doesn't work if you're just trying to learn advanced English words.

2. Vocabulary.com (The "Actually Explain It To Me" approach)

Most dictionary apps give you a cold, cryptic definition. Vocabulary.com writes definitions like a snarky college professor is explaining the word to you over a beer.

Why it's good: When you look up a word like "pedantic", it doesn't just give you synonyms. It gives you a paragraph breaking down the vibe of the word, how annoying pedantic people are, and exactly when to use it.

The catch: It's still an active destination. You have to remember to go there and look stuff up.

3. Readwise (The "Don't Forget What You Read" approach)

Readwise isn't strictly a vocabulary app. It syncs your highlights from Kindle, Apple Books, and Twitter, and emails you a random batch of them every morning.

Why it's good: When you highlight a smart sounding word in a book, you usually forget it by tomorrow. Readwise surfaces that exact paragraph a month later. You see the word exactly how the author used it.

The catch: It's pretty expensive just to remember quotes, and you can't easily filter it to just show you vocabulary.

4. Ozdic (The Collocation Dictionary)

If you're learning English, you don't just need to know what "heavy" means. You need to know that you can say "heavy rain" but you can't say "heavy wind" (it's strong wind). These are collocations.

Why it's good: You type in a word, and it shows you every adjective, verb, and preposition that naturally pairs with it. It is the holy grail for writing essays that sound native.

The catch: The website looks like it hasn't been updated since 2004.

5. Wordie (The Contextual Highlighter)

Okay, I'm biased here. But Wordie exists specifically to solve the problems of all the tools above.

You find a word you don't know while reading an article. You highlight it and save it to your Wordie vault. From then on, every time that word appears on any website you visit, Wordie highlights it.

Why it's good: It uses contextual highlighting. You don't review flashcards. You just browse Reddit, Wikipedia, and the news. When your saved words appear in the wild, they glow. You see them used dynamically across different contexts, locking them into your implicit memory.

The bottom line

The best tool to improve your vocabulary is the one you don't have to force yourself to open. Stop treating language like math flashcards. Let the words come to you.
