Customize your learning experience
Translate words or sentences
Choose the language you want to translate from. It doesn't have to be the same as in Duolingo. Translate words or sentences and choose how much to translate.
Ignore the domains you don't want to translate
Some domains just shouldn't be translated. For example, domains related to your work. You can add them to the ignore list with one click.
Use tooltips to see the original text
Hover the translation to see the tooltips with the original meaning of the word.
Don't translate <code blocks>, input fields, or links
Code blocks and input fields aren't translated. And you can optionally also skip translating links.
Why Duolingo Alone Doesn't Make You Fluent
You don't see enough text
Duolingo is great at bite-sized lessons. But you don't see enough text to start seeing patterns and start thinking in the language. You need a lot of comprehensible input for that.
The text is too simple and meaningless
Duolingo does have a lot of sentences that are theoritically useful. But they are practically meaningless because they don't have any immediate purpose. You are not trying to visit a museum in Spain while you are using the phone on your couch in England.
Trying to memorize grammar explicitly isn't that useful
No child ever learned their mother tongue by studying grammar and then consciously applying it. In fact, it's very difficult to think about grammar while speaking. You do need some but you'll pick up the rest subconsciously by seeing lots of text.
Duolingo doesn't teach you based on your interests
It forces you into a learning track. But people have different interests that have different vocabulary. You can't standardize interests.
Benefits
Works with your habits not against your habits
There's no extra app or website you have to open. Just keep doing what you always do - browsing the web. And you'll keep learning every day.
Learn the lingo you need
As you browse the pages you are interested in, you'll champion the vocabulary you actually need to use.
No nonsense sentences
Duolingo sometimes teaches you sentences that don't make sense. "The cow opened its favorite book" and "The cat wrote a letter in Japanese" are actual sentences you'll "learn" in Duolingo. Ever seen a cat write a letter in Japanese?
Give meaning back to your language learning
Most sentences in Duolingo do make sense. But there's no immediate use for them. I'm not trying to order wine in a restaurant while I'm on my couch looking at my phone. With Duolingo Ninja you'll learn the vocabulary you actually need.

“I created Duolingo Ninja to immerse myself in Spanish, not just do daily dry repetitions on Duolingo. Translating parts of web pages to Spanish keeps my vocabulary fresh without having to change my habits.”
