Hello! I finished school recently, and I've spent my time working on Nuenki (https://nuenki.app). It's a browser extension that translates sentences at your difficulty level into your target language and lets you quickly compare to the original by hovering.
You naturally pick up the language as you browse, checking the original when needed.
Translations are handled by DeepL, which is 3-6x more accurate than Google Translate[0].
You can use it for free for 24h, no card details required. I'd really appreciate feedback!
