German, Spanish, and French.
Einlang understands each language's exact grammar patterns - cases, conjugations, agreement - so every explanation, exercise, and vocabulary list is built for the specific rules on the page you scanned.

The hard part
The case system breaks every sentence.
German has four grammatical cases - Nominativ, Akkusativ, Dativ, Genitiv - and every noun, article, and adjective changes form. That is 16 article forms before a single sentence makes complete sense.
How Einlang handles it
Every word on your scanned page is case-tagged. Tap any noun and see which case it carries and exactly why - the margin note a private tutor writes by hand.
What your tutor covers
- Cases explained as they appear - Nominativ to Genitiv
- Verb forms laid out for every conjugation in the chapter
- Compound words split and translated part by part
- Separable verbs flagged where they split in the sentence
- Adjective endings tied to the noun they describe
- Umlaut rules shown with examples from your own page

The hard part
Two verbs for "to be" - and neither is obvious.
Ser and estar both translate as "to be," but they are not interchangeable. The distinction is not about rules you can memorise - it is about meaning, context, and intent. Books state it once. Learners misuse both for years.
How Einlang handles it
Einlang flags every ser and estar in your chapter and explains the reason for that specific choice - grounded in your own textbook's sentences rather than invented examples.
What your tutor covers
- Ser vs. estar - when to use each, in your chapter's own sentences
- Every tense your page uses, conjugated and explained in full
- Subjunctive mood exercises built from what you scanned
- Gender agreement traced sentence by sentence
- Reflexive verbs identified and shown in context
- Preterite vs. imperfect - the distinction a tutor would draw

The hard part
Gender follows every noun through the sentence.
French assigns every noun a gender - masculine or feminine - and that gender controls every article, adjective ending, and past participle that follows. There are no reliable patterns. The gender must be learned with each word, then traced through everything that depends on it.
How Einlang handles it
Einlang tags the gender of every noun on your scanned page and shows the ripple effect - how it changes the article, adjective ending, and verb agreement in that specific sentence from your chapter.
What your tutor covers
- Noun gender tagged wherever it appears, with the downstream agreement shown
- Être vs. avoir in passé composé - which to use and why, in context
- Adjective agreement traced to the noun it modifies on each line
- Subjunctive triggers identified and explained sentence by sentence
- Liaison rules shown where they apply on your page
- Accent marks explained as pronunciation and spelling guides
