Academic rigour · how the material is made

Practice you can actually trust.

A drill is only worth doing if it’s correct. So every item on drill is grounded in an authoritative curriculum and grammar, calibrated to your CEFR level — and rewritten the moment the data says it fell short.

Where the exercises come from

Nothing here is improvised.

Behind every gap, translation and dictation is the same short pipeline — from a reference you could look the rule up in, to the item on your screen.

A
The authoritative sources

Each language is grounded in its official curriculum framework and the single most comprehensive grammar reference for that language — the volume linguists and serious learners treat as canonical.

B
Mapped to the CEFR ladder

Every rule, tense and construction is placed on the A1–B2 scale, so an item can be pulled at exactly the level a learner is ready for.

C
The item you practise

Each exercise is calibrated a notch above your level, with the answer hidden — real production, drawn straight from the sources above.

Language by language

Each course sits on an official curriculum.

We don’t invent a syllabus. Each language follows the framework its own standards body publishes — the same one behind its official exams.

SpanishA1–B2
Scope & level

Grounded in the Plan Curricular del Instituto Cervantes — the reference syllabus behind the DELE exams — and cross-checked against the most comprehensive Spanish grammar.

GermanA1–B2
Scope & level

Aligned to the Goethe-Institut exam track and the official CEFR course sequence, cross-checked against the most comprehensive German grammar.

TurkishA1–B2
Scope & level

Built on the Yunus Emre Institute’s official curriculum (YDS / TÖMER track), cross-checked against the most comprehensive Turkish grammar.

What “rigorous” means here

Four things we don’t compromise on.

Source-grounded

Every rule, exception and explanation is lifted from a definitive reference — never improvised on the spot.

Calibrated to level

Locked to your CEFR band. Items sit one notch above where you are — challenging, never over your head.

Reads like a person

Sentences are checked to sound natural, not like textbook filler. Real prose, not robotic drills.

Deliberate coverage

Curated, level-tuned lists of words and structures with real spread — no looping on a handful of favourites.

Produce, don’t recognise

The plateau doesn’t break by tapping the right answer.

Every drill has to pass one test: does the learner construct the language, or merely recognise it? Recognition is what leaves intermediate learners understanding everything and freezing when it’s their turn to speak. So there’s no multiple-choice main mode — you write, and an AI examiner grades what you wrote across grammar, vocabulary and discourse.

TranslationRichest signal

Produce a whole sentence from meaning alone — the openest task, so it reveals the most about grammar range and vocabulary.

ClozePrecision

One grammar point, isolated inside real context — tense, agreement, case, mood — filled in by hand, not chosen from a list.

Sentence constructionSpontaneous

Build a target structure from a prompt and nothing else. Syntax under load, the way it happens in real speech.

Free writingExam-style

Open paragraphs graded on the criteria the DELE and IELTS use — the richest source of signal in the whole app.

Vocabulary recallActive

Retrieve the word from its meaning or context, monolingual at higher levels — recall, never recognition.

Contextual paraphraseFlexibility

Say the same thing another way — synonyms, register shifts — so you own the idea, not one memorised phrasing.

DictationListening

Neural-voice audio couples the ear to spelling and production — you write down what you hear.

Conjugation drillRepair

The deliberate exception: a targeted morphology drill, used as remediation to make inflection automatic.

And it keeps getting better

The material improves every week.

Rigour isn’t a launch-day checkbox. Every attempt is scored, so when an item’s success rate drops below what a well-pitched exercise should hit, it’s surfaced for review. Learners can also flag any item directly. Either way, we rewrite it and release the fix to everyone.

A success rate that low usually means the item, not the learner, is off.

The problem. The gap gave no hint which conjunction was wanted; several felt plausible, so most learners were guessing.

Rigorous, and never finished.

Practise on material that’s grounded in the grammar and sharpened every week by real results.
