Simply Fluent
Everything below was checked in October 2026, including the part about how far Duolingo now takes you, which changed in April 2026 and which most articles on this question have not caught up with.
You have a long streak. Maybe a gold owl. And then you open a news site, or a novel, or a film without subtitles, and almost none of it lands. That gap between "I have done hundreds of lessons" and "I cannot follow a conversation" is the reason this question gets searched so often.
The gap is real. It is also normal, and it is smaller than it feels.
What level does Duolingo get you to?
Since April 2026, nine Duolingo courses teach content through B2, the fourth of six levels on the CEFR scale. That covers nine courses, not the whole catalogue.
That changed recently, and most advice about what comes after Duolingo still rests on the old claim: the courses stop around A2, so you are on your own from there. On 22 April 2026, Duolingo announced that nine of its courses now teach content through B2: English, Spanish, French, German, Italian, Portuguese, Japanese, Korean and Chinese. In its own words:
Previously, most of these learners could only complete content up to A2 (Duolingo Score 59).
Duolingo describes someone at the end of B2 as an "independent user" of the language, able to interact with other speakers, understand certain complex texts and give their views on a wide range of topics.
Two caveats:
- This applies to nine courses. If you are learning any other language, check how far your own course goes before assuming either A2 or B2.
- Finishing the content is not the same as having the level. Course content aligned to B2 is a syllabus. Whether you personally are at B2 depends on how much of it stuck.
So check whether your course now has B1 and B2 sections you never saw. If it does and you enjoy the lessons, keep going. Either way, you do not have to wait for the last lesson before you start reading.
What does Duolingo teach you?
A real foundation, and Duolingo has published research on how much it teaches.
Duolingo's own research says that French and Spanish learners who completed five sections knew as much as university students who took five semesters of language classes. The study behind it tested reading and listening, not speaking. That is Duolingo reporting on Duolingo, so weigh it accordingly, but the direction is not controversial. A separate Duolingo study from 2021, run and reported by the company, tested 258 learners at the end of Unit 5 on the Pearson Versant speaking test: 66% of Spanish learners and 53% of French learners scored A2 or higher for speaking, having used no other study materials.
That is a foundation. You have a base of passive vocabulary, the sound of the language in your head, and the core grammar in your hands. Nothing in this article replaces that, and nothing here works without it.
Is Duolingo enough to become fluent?
On its own, no. It leaves three gaps, and knowing which one is your problem is most of the work.
1. Volume. Real language comes in paragraphs, at length, with no vocabulary ceiling. The jump from "I know 2,000 words" to "I can read a novel" is mostly a jump in hours spent with long text, not a jump in method. I have written about how many words you need to read a novel, and the number is larger than you might think, and less scary.
2. Unpredictability. In a lesson, you know roughly what the sentence is going to be about. In a conversation, you do not. Recognising a word you have met a hundred times, at speed, out of context, is a different skill from recognising it in an exercise where you already know the topic.
3. Production under pressure. Typing a sentence with time to think is not speaking. This is the gap Duolingo has narrowed with Roleplay and Video Call in its Max tier, and in my view it is still the gap apps serve least well.
What should I do after finishing Duolingo?
Pick the fix that matches the gap holding you back.
| What is missing | What closes it | What it looks like in practice |
|---|---|---|
| Vocabulary breadth, reading stamina | Extended reading in the language | 20 minutes a day with a book you can mostly follow |
| Ear for real speech | Listening with the words in front of you | Reading along with the audio, films or series with dual subtitles, podcasts for learners |
| Speaking fluency | Talking to a person | A weekly tutor session, or a language exchange partner |
| Grammar you half-know | A reference grammar or a course | Looking things up when you hit them, not studying them upfront |
| The daily habit | Keep using Duolingo if you enjoy it | Your usual lessons, with reading alongside them from the start |
If you can read a newspaper and cannot order a coffee, your gap is speaking. Book a tutor.
How do I practise speaking after Duolingo?
Talk to a person every week, ideally a tutor who corrects you.
Get a tutor. Online tutoring marketplaces let you book one-to-one lessons with individual teachers, who set their own rates, so what you pay depends entirely on who you book. For speaking, I would put an hour a week with a person who corrects you ahead of any number of app lessons. Nothing on a phone reproduces the specific pressure of a human waiting for you to finish a sentence.
Or find an exchange partner. Free, and worse. Free because nobody is charging you, worse because a partner is not a trained teacher, may not correct you, and conversations can drift into English. Fine as a supplement, weak as a foundation.
If you took the Max tier for Roleplay and Video Call, keep using it. Talking to a patient machine is a real rehearsal, and it lowers the terror of the first human lesson. It is a rehearsal, though, not the performance.
How do I understand books and native speech after Duolingo?
Spend hours reading and watching material made for native speakers, at a level where you follow the sense. This is the gap reading and watching can close, and it is the part with the most confused advice attached to it.
The underlying idea is not complicated: you get better at understanding a language mostly by understanding a lot of it, at a level where you follow the sense without translating every word. You need hours, and hours only happen if the material is enjoyable enough that you keep going.
Two routes work: watching and reading. Watching trains your ear, and reading can too if you play the audio while you follow the text.
Video gives you real speech with the pictures to help. Lingopie puts dual interactive subtitles over TV shows, and Migaku turns sentences from Netflix and YouTube into flashcards.
Reading is better suited to vocabulary breadth and grammar recognition, because your eyes can go at your own speed and you can stop. It is also where a post-Duolingo learner has the biggest immediate advantage: you already have enough words to read something.
Reading while listening adds the ear to that. You follow the text while a voice reads it, so you see and hear each word at the same moment and can connect its shape on the page with its sound. In a 2008 study with 35 Japanese university students, the students picked up about 2 percent of the new words when they only listened, against roughly 15 to 16 percent when they also had the written text. In a 2009 study with 84 college students, learners understood short stories about 10 percent better when they read while listening than when they only listened. And in a 26-week study from 2011, learners who read along with audiobooks more than doubled their score on a dictation test, where you write down what you hear at normal speed.
The first two gains are measured against listening alone, and the 2011 group was compared with learners in a regular class. Against silent reading, the 2008 study found similar vocabulary results with or without the audio. The 2011 study had only seven learners in the reading-while-listening group, so its numbers need repeating at a larger scale. I went through all three in reading while listening. Simply Fluent can read any book aloud with your phone's own voice while you follow the text, including books you add yourself.
What made me give up the first time I tried to read a book in Dutch was the lookup tax: unlocking my phone and typing a word into a translator, again and again, until the story stopped being a story. Reading apps exist to reduce that tax in different ways; if you're choosing one, I keep a comparison of the reading apps.
What should you do next at A2, B1 or B2?
Keep using the course if you enjoy it, start reading alongside it as early as you can, and add what fits your level from the list below.
If you aren't sure which of these is you, the free reading level test (Spanish, French, Portuguese, German, Italian and Dutch) gives you a CEFR level after up to three short passages.
Still inside the course. If you enjoy it, keep going, and if your language is one of the nine, the B1 and B2 sections added in April 2026 give you more of it. But start reading now rather than after the last lesson, a few pages a day of graded short stories or parallel texts next to your lessons. The more you read, the better you get at reading, and the more words you pick up along the way.
Finished the course, roughly A2. Graded material is a good next step: parallel-text stories, or graded short stories written to A1 and A2. If you would rather read a novel, with a translation one press away you can start one earlier than you might expect, and a book you want to come back to is worth a lot. I wrote about picking your first book, and at A2 it is a choice between the two, not a rule.
Roughly B1, understand a lot, produce very little. Split your time. Reading for volume, one tutor session a week for production. If you only do input at this stage, you get no practice at speaking, and speaking is the part that will feel stuck. If it feels like nothing is improving, that is normal and it has a name: the intermediate plateau.
Roughly B2, can read but it is slow. Read novels, in volume, and don't hold up the story to solve every word. Look up what you want to know and keep going. Partial understanding is fine, and many gaps close as you keep reading; I made that case in you don't have to understand everything. This is also where films without subtitles stop being punishment.
The short version
If you enjoy Duolingo, keep using it. Do not wait until you finish the course to start reading: start alongside the lessons, as early as you can, with something easy enough to follow. The more you read, the better you get at reading, and the more words you pick up. As you go, work out which of the three gaps is yours, volume, ear or production, and add what closes it.

Common questions
- What should I do after finishing Duolingo?
It depends on which gap is holding you back. If you can follow written sentences but freeze in conversation, book a tutor: nothing else replaces speaking. If you understand the app but not books, films or podcasts made for native speakers, you need volume of input, which usually means extended reading, reading along with the audio, or watching with dual subtitles. If you are not sure which gap is yours, start with input, because you cannot say what you have never met.
- What level does Duolingo get you to?
As of April 2026, nine courses (English, Spanish, French, German, Italian, Portuguese, Japanese, Korean and Chinese) carry content through CEFR B2. Duolingo says that before that expansion, most learners in those courses could only complete content up to A2. Other courses in the catalogue are shorter, so check your own course rather than assuming. A lot of "after Duolingo" advice online predates April 2026 and still says A2 across the board.
- Is Duolingo enough to become fluent?
On its own, no. Duolingo's own research says French and Spanish learners who completed five sections knew as much as university students after five semesters of language classes, which is a real foundation and not fluency. The missing piece is volume and unpredictability: books, native speech and conversations, where nobody has pre-selected the vocabulary for you.
- Should I keep my Duolingo streak going while doing something else?
If you enjoy it, yes, keep going. Just do not wait until you finish the course to start reading. Start reading alongside the lessons as early as you can, with something easy enough to follow, because the more you read, the better you get at reading, and the more words you pick up along the way.
