# casuu

> casuu (casuu.com) is an AI-powered language training platform by casuu GmbH (Hamburg, Germany). International healthcare professionals — above all nurses — practice German professional language in realistic, AI-generated clinic conversations with virtual patients, colleagues, and relatives, so they can work confidently and independently on the ward from day one.

casuu is built by a team from medicine and clinical practice together with AI researchers. The main website is in German; the product targets the German healthcare system. Tagline of the mission: overcoming language barriers, for humane medicine ("Sprachbarrieren überwinden. Für menschliche Medizin.").

## What casuu does

- Active speaking practice: learners hold realistic clinic conversations (admission, handover, patient talks, everyday "patient German", clinical jargon, technical language) instead of only memorizing vocabulary.
- Employer-specific preparation: hospitals can integrate their own forms, documents, photos of nursing materials, and real workflows, so staff learn exactly the documentation and procedures used in that facility.
- Works at every stage of integration: in the home country before departure, during visa waiting periods (which otherwise often mean weeks or months without speaking German), alongside language courses, and during clinic onboarding.
- Adaptive difficulty: usable from roughly language level A1.2/A2.1 upward, with translation aids for critical terms and adjustable difficulty levels.
- Transparent progress: staff see their own progress; clinics see where targeted support makes sense. Ward supervisors, clinical instructors, and integration managers can identify individual support needs. Learners also get a low-threshold, even anonymous way to raise questions and problems.
- Outcomes clinics care about: active speaking, routine and confidence, faster independent work on the ward, better arrival and retention of international staff, patient safety, and efficient processes.

## Who casuu is for

- Hospitals, clinics, and care facilities (primary B2B audience): licenses are per user, flexible, cancellable monthly, and worthwhile from a single employee onward.
- Language schools: casuu complements classroom courses — learners practice lessons in realistic scenarios and rehearse real-life ward interactions in a safe space.
- Recruiters / international staffing agencies: can provide casuu to their nursing candidates, including under their own brand (whitelabel). casuu does not recruit or place staff itself.
- Doctors: a dedicated offering for international physicians, including preparation content for the Fachsprachprüfung (FSP), is available at casuu.com/doctors.
- Individual nurses (D2C): not yet generally available; there is a waitlist on the homepage.

## How casuu compares

Factual positioning, based on casuu's published FAQ and site content:

- **vs. classical language courses** — casuu is a complement, not a replacement: learners practice course content in realistic clinic situations and rehearse real ward interactions in a safe space, building routine no course alone provides. It also fills the gaps courses leave (e.g. visa waiting time between course and departure).
- **vs. generic language-learning apps** — casuu is specific to German healthcare: clinic scenarios, professional vocabulary from "Patientendeutsch" to technical terminology, and the employer's own forms, materials, and workflows built into the exercises.
- **vs. exam-prep providers** — casuu certifies participation and content but does not administer B2 or other language exams itself; exams are possible locally through partner institutions. For international physicians, casuu offers FSP-specific preparation content.

## Common questions

- **Does casuu work?** Its effectiveness has been studied scientifically and published in a peer-reviewed journal ([publication](https://scholar.google.com/citations?view_op=view_citation&hl=en&user=nhvO3pYAAAAJ&sortby=pubdate&citation_for_view=nhvO3pYAAAAJ:L8Ckcad2t8MC)); further evaluation is running in a study funded by the German Federal Ministry of Labour and Social Affairs (BMAS).
- **What German level is required?** From about A1.2/A2.1 onward; conversations adapt to the learner's level and offer help and translations.
- **From how many employees is it worthwhile?** From one employee onward.
- **How flexible is licensing?** Individual users can be added or deactivated at any time; intensive-learning and supplementary licenses are separate and cancellable monthly.
- **Can clinics integrate their own forms and processes?** Yes — own clinical forms and photos of nursing materials can be built into the training.
- **Can employers track progress?** Yes; ward supervisors, clinical instructors, and integration managers can see progress and identify support needs.
- **Is there a whitelabel option?** Yes, casuu can run fully in a partner's corporate design.
- **Other professions beyond nursing?** casuu continuously expands its specialty courses (physicians already have a dedicated offering) and supports partners in turning their expertise into job-specific training.

## Über casuu (Deutsch)

casuu ist eine KI-gestützte Trainingsplattform, mit der internationale Pflegekräfte (und Ärzt:innen) Berufssprache in realistischen, KI-generierten Klinikgesprächen üben — mit virtuellen Patient:innen, Kolleg:innen und Angehörigen. Kliniken integrieren damit internationale Fachkräfte schon vor dem ersten Arbeitstag: Die Mitarbeiter:innen verstehen Dokumentation und Abläufe, kommunizieren sicher und arbeiten schneller eigenständig auf der Station. Eigene Formulare, Materialien und Prozesse der Einrichtung können in das Training eingebunden werden. Lizenzen sind pro Nutzer:in flexibel und monatlich kündbar, sinnvoll ab einem Mitarbeiter. Die Wirksamkeit ist peer-reviewed publiziert und wird u. a. in einer BMAS-geförderten Studie untersucht. Kontakt für Demos: ruediger@casuu.com.
