One by one

Field Words or Readlang

Choose Readlang if… you read long texts in any of its hundred-plus languages and want to translate as you go. It's the closest option, and it covers far more languages.

Choose Field Words if… you're learning English from Spanish and want the meaning written for your sentence, with register and translation together, in a tool made for that pair of languages.

Field Words or Reverso

Choose Reverso if… you mainly need to look up translations fast, with plenty of real usage examples. Its extension is free and spots multi-word expressions.

Choose Field Words if… you want more than a lookup: to keep the word, its sentence, its source and a scheduled review, all in the browser, with no need for a mobile app.

Field Words or LingQ

Choose LingQ if… you want a complete lesson-based method, with audio and content, and you set aside sessions to study.

Choose Field Words if… you don't want to import anything: read where you already read, select the word and carry on. The free plan doesn't stop you at 20 words.

Field Words or Language Reactor

Choose Language Reactor if… you mostly learn from shows and videos. It's built for Netflix and YouTube subtitles, and Field Words doesn't handle video.

Choose Field Words if… you mostly learn by reading: articles, forums, documentation or email.

Field Words or Toucan

Choose Toucan if… you're starting a language and want to see single words effortlessly as you browse. Its website lists eleven languages, and when we looked English wasn't among them.

Choose Field Words if… you already read in English and want to decide for yourself which words are worth it, rather than have the extension choose.

Field Words or Anki

Choose Anki if… you want total control over your cards, for any subject. It's free on desktop and Android, very powerful, and uses the same kind of algorithm.

Choose Field Words if… you'd rather not write cards: a catch already comes with its sentence, meaning, translation and source. And if you want to carry on in Anki afterwards, CSV export is coming to every plan.

Where Field Words falls short

So you can decide with the whole picture. Today, Field Words:

Only runs on desktop Chrome for now, with no other browsers. The app for Android and iPhone is on its way, but it isn't in the stores yet.
Will know less on a phone. The system hands over only the selected text, so you select the whole sentence to keep it, and a catch records the app rather than the page. On iPhone, not even the app.
Is only made for Spanish speakers learning English. The reverse comes later.
Doesn't handle video or podcasts: it needs text you can select.
Doesn't export to CSV or sync across devices yet, so your phone and your computer will keep separate collections at first. Both are planned.

What about Google Translate or DeepL?

They're excellent translators and still useful for getting through a whole text. But they answer a different question: what does this say, not how do I remember it. Plenty of people use them alongside a tool like this one.
