Deutsch English Language Lab
Bilingual practice studio — search, listen, scan, and read your way to fluency.
"Most language tools answer 'what does this word mean.' This one is built for the next question — how do people actually use it?"
Why it exists.
I started this while learning German. The lookup tools I tried would surface a definition but rarely the rest of the picture: how the word lands in different sentences, what it shares meaning with, what its rough English neighbour is. Switching between four tabs to assemble that picture got old fast.
The Language Lab is one page that returns the full picture in a single round-trip. Type a word — German or English — and you get the translation, the source-language meaning, the target-language meaning, real example sentences, and a list of synonyms. Bidirectional with a single toggle.
Two practice modes sit alongside the search. The microphone mode streams a live transcript and translation while you speak, useful for pronunciation drills and shadowing. The camera mode scans paragraphs from printed material via server-side Gemini — a one-tap way to read through a German book with comprehension support without retyping anything.
A quieter feature is the CEFR rewrite slider. If you're A1, the example sentences come back at A1 complexity. As you climb, the rewrites stretch into B1 territory. Same input, complexity tuned to your level.

Under the hood.
Worth knowing.
- Static, dependency-light frontend — loads fast on the worst hotel Wi-Fi.
- Camera processing is server-side so the model swap doesn't ship to every browser.
