Spoiler alert — only for the vocabulary.

Understand English podcasts without losing the thread at every other word.

Wordspoiler shows you the hard words and phrases of an episode before you listen. Free during the beta.

Wordspoiler is for learning English. Translations into German. Spanish, Polish, Swedish, Italian, French, Hindi, Norwegian, Danish and Finnish are planned.

Never listened to a podcast? It’s like radio, but whenever you want, for example in Spotify. An easy start is BBC Learning Easy English: six minutes an episode.

Words from the episode

ExampleFrom an episode about everyday lifeapprox. 11:30

I was reluctant to ask, the bill kept creeping up, and in the end I just had to bite the bullet.

  • reluctantwordnot wanting to do something
  • creep upphraseslowly get higher
  • bite the bulletphrasedo something hard that you don’t want to do

Here in easy English. In the app, you see it in your native language. Today that is German; more languages are planned.

You know every word, and still don’t get the sentence.

Some phrases are made of words you know and mean something else entirely. When you listen, you only notice once the sentence is over.

  • I said yes to everything, and now I’m in over my skis.

    You know every word:

    in over my skis

    taking on more than you can handle

  • Those two are up to no good.

    You know every word:

    up to no good

    planning something bad

Then there are the words you really don’t know. You see both before the episode.

No time to look words up while you listen

When you read, you can look a word up. When you listen, the speaker keeps talking. A word you don’t know leaves a gap, and it takes the next two sentences with it.

Often only a few important words or phrases are missing. You can look at them beforehand.

You shouldn’t have to give up a podcast that interests you. That’s why Wordspoiler shows you the words before the episode.

  • Reading

    I was reluctant to ask, so I waited.

    You look it up and read on.

  • Listening

    I was ? to ask, so I waited

    The speaker keeps talking. The next words are gone too.

Spoil the words, then press play

  1. Pick a podcast

    Choose a podcast from the catalog, or add one you already listen to.

  2. Run through the words

    20 to 30 words and phrases, each with its sentence from the episode and roughly where it comes up. Swipe left for “I know it,” right for “Show me.” It takes two or three minutes.

  3. Listen, practice later

    You listen in your own podcast app, as always, like Spotify or Apple Podcasts. When the word comes up, you already know it. You go over the new words later in short rounds.

What you know, you won’t see again

Your progress

You see how many words you already know. No streaks, no points.

Why the words first?

What the research says.

In a study with 93 learners of English, learning the words first did the most for listening comprehension (Aldukhayel 2023). The study is small, and others found no advantage. What is certain: the more words you know, the more you understand (Zhang & Zhang 2022, over 100 studies).

Try it with a podcast that interests you. More in the guide Words before you listen.

Frequently asked questions

Is Wordspoiler a podcast player?

No. Wordspoiler has no player of its own. You run through the hard words and phrases of an episode first, then press play in your podcast app, like Spotify or Apple Podcasts.

What level is Wordspoiler for?

From about A2 (you understand simple sentences) upwards, from school English to fluent. At the start you say how good your English is. After that, what counts is what you swiped away with “I know it,” so the words fit you a little better with every episode.

Do I learn English, or another language?

English only. Wordspoiler is for learning English. The app translates the words into your native language. So far that’s German. Spanish, Polish, Swedish, Italian, French, Hindi, Norwegian, Danish and Finnish are planned.

Is Wordspoiler coming to iPhone?

Wordspoiler is coming to Android and iPhone. I'll give a date once there is one.

How much does Wordspoiler cost?

It’s free during the beta, with no ads.
