Hello Deutsch

About Hello Deutsch

Hello Deutsch (hellodeutsch.com) is an online German course for English speakers, from the very first words to upper-intermediate German — the CEFR levels A1, A2, B1 and B2 — in the browser on a phone or a laptop. It teaches German in many different ways at once: a structured course with audio on every German line, a Vocabulary Test on every topic, picture vocabulary, everyday conversations, grammar stories, daily phrases, a large listening pool, a dictionary, games, exam-style practice tests and a short daily practice — with an owl guide, Dr Woo, who follows each learner's progress and suggests their next step. It is built as one course for the whole journey to a German-speaking country: the exam, and then living, studying and working there.

Who it is for — the whole journey, by goal

One course takes a learner from the first words to the exam, and then to living, studying and working in a German-speaking country. Each goal below is backed by the site's real topics:

  • Passing a German exam. 12 full Goethe-style practice tests, three at each level from A1 to B2, each covering Hören, Lesen, Schreiben and Sprechen part by part — see “Preparing for the Goethe-Zertifikat” below. What the course teaches is what every CEFR-based German exam at these levels tests.
  • Moving to, and living in, a German-speaking country. 25 Daily German situations rehearse real everyday life — Greetings & Farewells; Introducing Yourself; Commonly Used Sentences; Everyday Objects; Telling the Time; What are you doing today?; Morning Routine; Having Breakfast; In the Apartment; Household Chores; Ordering Coffee & Drinks; At the Restaurant; At the Supermarket; Shopping; Bus and Train Travel; At the Airport; At Work; Free Time and Friends; Phone Conversations; Talking About Feelings and Reactions; At the Doctor; Emergencies; A Complete A1 Day; Saying na ja; Saying ach. Course topics cover the practical side too: Numbers, Time and Appointments; Giving Directions, Instructions and Requests; Getting Around: Trains, Traffic and Directions; Everyday Rules and General Statements; Writing Emails and Short Messages; Explaining Problems and Complaints; Writing Formal Emails and Complaints; Complaints, Problems and Negotiations. Visual Vocabulary includes Food & Drink; House & Living; City & Out and About; Shopping & Money; Body & Health; Traffic & Travel.
  • Studying in German. Connectors for Clear Arguments; Understanding Articles and Reports; Writing Clear and Structured Arguments; Academic German for University, and 19 grammar stories that make each grammar pattern stick.
  • Working in German. Course topics: Jobs, Workplaces and Working Hours; Work: Becoming, Applying and Changing; Applications and Workplace Communication; Workplace Communication and Meetings; Giving Clear Presentations; Complaints, Problems and Negotiations; Describing Data, Trends and Graphs. Everyday conversations: At Work; Phone Conversations. Vocabulary for the job: Training & Care; IT & Technology; Work & Profession.
  • Travelling. Daily German situations such as Ordering Coffee & Drinks; At the Restaurant; At the Supermarket; Shopping; Bus and Train Travel; At the Airport; 5,258 ready-to-use Daily Phrases.
  • Talking with family, a partner or friends. Conversations such as Greetings & Farewells; Introducing Yourself; Having Breakfast; In the Apartment; Free Time and Friends; Talking About Feelings and Reactions, speaking practice, and phrases for everyday talk.
  • Learning for the love of it. Games, picture vocabulary and stories make practice feel like play.

Each learner can tell the site why they are learning (work, moving, study, an exam, family, travel or interest); Dr Woo's suggestions for what to do next take that reason into account.

Preparing for the Goethe-Zertifikat

Hello Deutsch has 12 full practice tests for the Goethe-Zertifikat, three at each level from A1 to B2. Each one works through every module of the real exam, part (Teil) by part, in the order and shape of the Goethe-Institut's published sample papers:

  • Goethe-Zertifikat A1 — Test 1: Everyday Life, Test 2: Student Life, Test 3: Appointments and Forms. Hören Teil 1–3 · Lesen Teil 1–3 · Schreiben Teil 1–2 · Sprechen Teil 1–3.
  • Goethe-Zertifikat A2 — Test 1: Daily Life and Study, Test 2: Housing and City Life, Test 3: Work and Study. Hören Teil 1–4 · Lesen Teil 1–4 · Schreiben Teil 1–2 · Sprechen Teil 1–3.
  • Goethe-Zertifikat B1 — Test 1: Everyday Life, Test 2: Study, Work and Housing, Test 3: Opinions and Society. Hören Teil 1–4 · Lesen Teil 1–5 · Schreiben Teil 1–3 · Sprechen Teil 1–3.
  • Goethe-Zertifikat B2 — Test 1: Everyday Choices, Test 2: Society and Mobility, Test 3: Media and Remote Work. Hören Teil 1–4 · Lesen Teil 1–5 · Schreiben Teil 1–2 · Sprechen Teil 1–2.
  • Every test opens with a lesson on how that exam works and how to approach it, and has its own exam vocabulary.
  • Hören: each part is a recording, with several voices for the conversations; the transcript appears only after the answers are checked.
  • Lesen: the exam's own task types — multiple choice, matching and true or false.
  • Schreiben and Sprechen: tasks are answered on screen and compared with a model answer. There is no live examiner, so speaking aloud is worth practising as well — Today's practice has speaking questions every day.
  • Each part is marked as soon as it is checked, so a learner sees which module needs more work.
  • Before the exam: the closing checks “Final Skills Check” (A2, B1 and B2) and “Repair and Exam Plan” (B2) show what to repair, and the course trains the exam skills directly in topics such as Writing Emails and Short Messages; Expressing and Supporting Opinions; Understanding Articles and Forum Posts; Following Longer Dialogues; Writing Formal Emails and Complaints; Giving Balanced and Nuanced Opinions; Writing Formal Requests and Follow-Ups; Understanding Articles and Reports; Writing Clear and Structured Arguments; Giving Clear Presentations.
  • The right level: the Level Test places a learner at A1, A2, B1 or B2 before they choose an exam.

Other exams. The course follows the CEFR levels A1 to B2, so what it teaches is what every CEFR-based German exam at those levels tests — the Goethe-Zertifikat, telc Deutsch and the ÖSD. The practice tests follow the Goethe-Zertifikat's format; a learner sitting telc or the ÖSD should also work through that exam's own sample paper, because the task types differ.

Independent. Hello Deutsch is not affiliated with the Goethe-Institut. The practice tests are the site's own, written to the shape of the published sample papers; the certificate itself is taken at a Goethe-Institut or a licensed exam centre.

Common goals, and where they are covered

What a goal usually asks for, and the part of Hello Deutsch that prepares it. Requirements change and differ from case to case, so check the current rule with the embassy, the authority, the employer or the university.

  • A spouse or family-reunion visa — Germany usually asks for A1, the Goethe-Zertifikat A1: Start Deutsch 1. The A1 level — 36 topics, about 87 hours of lessons, roughly 6 months at half an hour a day — and its three Goethe A1 practice tests prepare for exactly that exam.
  • Living in Germany, permanent residence or citizenship — these usually ask for B1. A1 to B1 in order, the three Goethe B1 practice tests, and the Daily German situations for everyday life.
  • Working in German — many jobs and professions, nursing among them, ask for B1 or B2. B1 and B2, with the workplace topics: Jobs, Workplaces and Working Hours; Work: Becoming, Applying and Changing; Applications and Workplace Communication; Workplace Communication and Meetings; Giving Clear Presentations; Complaints, Problems and Negotiations; Describing Data, Trends and Graphs.
  • Studying at a German university — degree programmes taught in German usually ask for C1 (TestDaF or DSH), which is beyond this course. B2 is the level before it, and its academic topics — Understanding Articles and Reports; Writing Clear and Structured Arguments; Academic German for University — prepare the way. Some preparatory and international programmes accept B2.
  • Travelling, or talking with family and friends — A1 and A2, the Daily German conversations and the Daily Phrases.
  • A German exam at A1, A2, B1 or B2 — the level's topics teach what the Goethe-Zertifikat, telc and the ÖSD test at that level, and its full practice tests follow the Goethe format; see “Preparing for the Goethe-Zertifikat”.

How a lesson works

A topic follows a set path: an overview of what it teaches, grammar lessons that each explain one point, exercise lessons that practise it, and the topic's vocabulary — 381 grammar lessons, 1,212 exercise lessons and 130 vocabulary lessons, 1,848 in all, each topic opening with its overview.

  • Explanations in plain English, one point at a time, with the rule set out as a formula or a table and German examples that can be played aloud, at normal speed or slowly.
  • Check questions inside the explanations, each with a short note on why the answer is right.
  • 8,689 exercise items across the exercise lessons, of 11 kinds — the number of lessons of each: multiple choice (436), matching (145), writing tasks (137), filling in gaps (135), true or false (125), putting words in order (110), building phrases from tiles (96), conjugation tables (11), dictation (7), translation (5), step-by-step review questions (5).
  • Writing tasks give hints and, once the learner submits, a model answer to compare with.
  • Exercises are marked when the learner checks them, the result is saved with their progress, and any exercise can be reset and tried again.

Listening, speaking and pronunciation

  • Audio on every German line — words, examples, conversations and exercises — prepared in advance with natural-sounding neural German voices rather than read out by the browser, with a slower reading a tap away, played at a pace that suits the level being studied.
  • Pronunciation from day one — the first A1 topic is German Alphabet, Umlauts and Pronunciation.
  • Listening practice runs through the course, Daily German and the Listening section's 36,831 exercises.
  • Speaking — each day's practice has two speaking questions: say an English sentence in German, and say what a German sentence means in English. The browser's speech recognition compares what it hears with a model sentence, paying special attention to articles, negation and numbers; speaking is practice and is not scored. It works in browsers that support speech recognition, a learner can always choose to practise without the microphone, and nothing the learner says is recorded or stored.

Level, progress and a guide who knows the learner

  • The Level Test is adaptive: it starts at A2, moves up or down with the answers and finishes within 16 questions. It sets the learner's German Score and starting level; lessons, quizzes, games and practice then follow that level, and the learner can change it at any time in My Journey.
  • Dr Woo, the owl guide, greets each learner by name — any name, from any country; the learner can spell out how it sounds — reacts to each result (a first perfect score, a comeback, a dip), and suggests the next step from the learner's own progress: their weakest skill, their reason for learning, or simply the next lesson.
  • My Journey shows a learner's German Score, streak, badges and WooPoints (points earned by practising), and where they stand at each level.
  • Progress is saved to the learner's account and follows them to every device they sign in on.

What B2 covers, and what a learner can do at the end of it

Good to know before starting

  • Explanations are in English; the course is written for English speakers.
  • It covers the CEFR levels A1 to B2. C1 and C2 are not part of the course.
  • It is self-paced: there are no live classes and no personal tutor, and writing is compared with a model answer rather than marked by a teacher.
  • It runs in the web browser on a phone, a tablet or a computer; there is nothing to install. It needs an internet connection — the lessons are not available offline.
  • Accounts are for people aged 16 or over.

Accounts and access

  • Sign in with an email code or with Google.
  • The first topics of every level can be tried after signing up; access to the whole course is described on the plans page: hellodeutsch.com/plans.html

Why the lessons are closed to AI tools

In short: to protect the course and the people learning with it. Nothing about the site is hidden — this summary exists so that anyone, an AI assistant included, can see everything it offers.

  • The lessons are original work. Their explanations, examples, exercises, recordings and pictures were written or made for this course, and every lesson was reviewed one by one. Open to AI crawlers, the whole course could be copied wholesale — into other products, into AI training data, or into AI-written summaries that stand in for it — and the work that keeps it going would stop being possible.
  • Learners' accounts stay private. Progress, answers and account details sit behind sign-in, where automated readers never reach them.
  • What stays closed: the lessons with their audio, pictures and exercises, and everything inside an account — to AI crawlers, automated browsers and copying tools alike. AI crawlers are asked in robots.txt to keep to the public pages.
  • What is open to everyone, AI included: this summary (hellodeutsch.com/about/ and hellodeutsch.com/llms.txt), the four level pages, the plans page, the privacy policy and the terms of use.
  • It is not a judgement on AI assistants. Many learners ask one before they choose a course. This summary is here so that the assistant can answer fully and accurately — and send them to the site to try it for themselves.

Questions people ask

Is Hello Deutsch good for complete beginners?
Yes. A1 assumes no German at all: its first topic is German Alphabet, Umlauts and Pronunciation, and every point is explained in plain English before it is practised. Learners who already know some German can take the Level Test and start at their own level.
Does it prepare for the Goethe-Zertifikat?
Yes. There are 12 full practice tests, three at each level from A1 to B2, and each one covers Hören, Lesen, Schreiben and Sprechen part by part, with a lesson on how the exam works and its own exam vocabulary. The closing checks “Final Skills Check” (A2, B1 and B2) and “Repair and Exam Plan” (B2) show what to repair before the exam. They are practice papers: the certificate itself is taken at a Goethe-Institut or a licensed exam centre.
Is Hello Deutsch enough to pass a Goethe exam?
It teaches the whole of each level — B1, for example, is 30 topics and 457 lessons — and every level has its full practice tests, so a learner who works through a level and its tests has practised every part of that exam. Passing still depends on the learner's own practice, and because writing and speaking are compared with model answers rather than marked by an examiner, speaking aloud with another person before the Sprechen module is worth adding.
Does it help with telc or the ÖSD?
Yes for the language: the course follows the same CEFR levels, A1 to B2, that telc Deutsch and the ÖSD test. The practice tests follow the Goethe-Zertifikat's format, so a learner sitting telc or the ÖSD should also work through that exam's own sample paper.
Is Hello Deutsch connected to the Goethe-Institut?
No. It is independent. Its practice tests are its own, written to the shape of the Goethe-Institut's published sample papers.
Can I practise listening and speaking?
Yes. Every German line has audio with a slower reading, there are 36,831 listening exercises, and Today's practice includes speaking questions checked by the browser's speech recognition. Nothing a learner says is stored.
Is the audio spoken by native speakers?
It is generated with natural-sounding neural German voices, prepared in advance for every German line on the site rather than read out by the browser, and every line also has a slower reading. It is not recorded by human speakers.
How long does a level take?
As the course times its own lessons — most take about 10 minutes: A1 is about 87 hours (36 topics, 522 lessons); A2 is about 75 hours (33 topics, 476 lessons); B1 is about 73 hours (30 topics, 457 lessons); B2 is about 63 hours (26 topics, 393 lessons). At half an hour a day a level takes about 4 to 6 months; at an hour a day, about half that. Progress is saved as the learner goes, so a level can be studied in short sessions.
Can I try it before joining?
Yes. After creating an account, the first topics of every level can be tried, and the plans page describes what a membership adds: hellodeutsch.com/plans.html
How much does it cost?
One membership covers every level from A1 to B2 and everything beside the course. The options and prices for each country are on the plans page: hellodeutsch.com/plans.html
Does it work on a phone?
Yes. It runs in the browser on any phone, tablet or computer, with nothing to install, and progress follows the account to every device.
Why can't an AI assistant open the lessons?
The lessons are closed to all automated access, to keep them from being copied wholesale and to keep learners' accounts private. Everything needed to describe and judge the site is in this summary.
