Both teach a language. One moves you forward ten minutes a day, the other takes you to a level you can put on your CV. The difference lies in how they are built.
A language app is an excellent tool. It maintains, it reviews, it builds a daily habit. Many people spend hundreds of hours on them.
And yet, very few come out of it able to run a meeting, write a professional email, or hold a technical conversation.
This is not a flaw in the tool. It simply does not do the same job.
### What an app does well
It breaks learning into short units, easy to repeat. It maintains memory, builds vocabulary, and keeps you in contact with the language.
That is valuable — even essential — between two serious study sessions.
But it moves forward through accumulation. Nothing guarantees that after three hundred lessons you have reached an identifiable level — because no level was targeted from the start.
### What a course does differently
A professional language course starts from the end.
It targets a level of the Common European Framework of Reference and works backwards to build the path. The six levels, from A1 to C2, each correspond to a distinct two-hundred-hour course — not a chapter within a single programme. Each stage exists because it is necessary to reach the next one, not simply because it comes later in a list.
This changes three things.
The progression is ordered. You do not tackle the conditional before the present tense is solid, nor negotiation vocabulary before presentation vocabulary. The order is not decorative: it determines what sticks.
The level is verifiable. At the end, you know what you can do — and you can describe it. "Understanding the key points of a professional discussion on a familiar topic" means something. "Three hundred lessons completed" does not.
The content is situated. Alongside the six general levels, specific pathways target precise uses: business English, technical English, conversational spoken English, preparation for recognised examinations. The vocabulary, phrasing and exercises differ, because what you will need to do with the language differs.
### How a pathway is built
A language pathway is built in stages of twenty modules.
Each module addresses a precise point: a grammatical structure, a vocabulary field, a communication situation. It includes a lesson, exercises, and a quiz that verifies the point has been mastered before moving on.
A language course contains five chapters and twenty modules, for a minimum of two hundred hours. This is not a formal constraint: it is what is needed to move from one level of the European Framework to the next.
Everything is open from the start. Learners progress at their own pace, go back whenever they wish, but the order remains the one that makes pedagogical sense.
### The question of speaking
This is where most online learning stops.
You can learn vocabulary alone, review grammar alone, do written exercises alone. Speaking, you cannot. You need someone there with you, and you need to be able to make mistakes without it feeling awkward.
This is what is most often missing for those who have accumulated hours on apps: they understand, they read, and they freeze the moment they need to produce.
Two features in our pathways address this.
Ninety-minute virtual classes, led by a specialist conversational agent. You speak, you correct yourself, you try again. No one judges you, which lifts precisely the block in question.
In-pathway support, which answers questions the moment they arise — on a grammar point, a turn of phrase, a pronunciation. Without waiting for the next session.
This is where artificial intelligence brings something no written material can replace: permanent availability, and unlimited patience.
### What this means for the catalogue
Sixteen languages are covered, from the most common to the most rare.
Some require particular treatment. Languages with non-Latin scripts require an additional progression: vocabulary is not introduced before the alphabet can be read. Ancient languages do not target conversation but the reading of texts, which entirely changes how the pathway is built.
A language catalogue is therefore not the same course repeated sixteen times. It is sixteen different constructions, sharing nothing but the method.
### A final word
The question is not whether apps are useful — they are.
The question is what you want to be able to do in six months. Maintain contact with a language, or reach a level you can name, justify and put to use.
These are two legitimate goals. They simply do not call for the same tool.
