Original teaching material
All written German scenes, translations, questions and keys are original editorial material. They are not research evidence or transcriptions of recordings. No public authority supplied the invented ticket conditions, delivery permissions or opening times. The examples train language relationships, not current practical rules.
Official product sources
- Jibber Jabber product facts JSON — plan prices, saving limits, supported languages, platform and included features.
- Jibber Jabber site summary — official overview and source navigation.
- Product feature guide — links to feature detail for the workflow discussed in the workbook.
The two machine-readable sources were retrieved on 9 November 2026. They state that product facts were reviewed on 28 October 2026. Prices are USD. We make Jibber Jabber, so these are first-party product sources, not independent reviews.
Claims we do not make
No research studies, learner outcomes, testimonials or performance rankings support these tasks. We do not map practice time to CEFR levels. We do not claim exact scene availability in the app. The written examples do not establish current routes, food ingredients, tenancy rights, repair methods or building access.
How to use a source
Use official product pages to confirm the tool's current facts. Use the original written key to check the exercise. Use your chosen real video's speech to check a transfer task. These sources answer different questions. Do not use a product feature list as proof that a particular scene exists, or a readable caption as proof of an actual service rule.
