Learn Dutch from real videos you'd actually want to watch, matched to your level and listening speed. Reelang turns the clips native Dutch speakers actually post into listening practice you can scroll. 13,000+ videos from the Netherlands and Flanders, from clear beginner-friendly speech to full native pace, A1 to C1. New to Dutch? Start anyway You do not need any Dutch to begin. The feed opens with the easiest Dutch it has and speeds up as you do: short clips, slower and clearer speech, the most common words first. Real Dutch is something you follow on day one, not something you work up to. How it works • Real Dutch videos, made for Dutch speakers, not for textbooks. • A feed graded two ways: by your level, and by how fast people actually speak. • Every clip says where it comes from, so you always know which Dutch you are hearing. Flemish is not an afterthought: it is its own feed with over a thousand clips, and you will meet Surinamese Dutch in the mix too. • Smart Subtitles underline the words worth learning, the most common 500, 1,000 and 2,000 words in Dutch, so you can see at a glance which word is worth a tap. • Tap any word in the captions to see what it means, right there in the sentence. • Learner insights with Reelang+: short notes on the Dutch worth knowing in a clip. Focus mode, the guided way in Do not just watch a clip, work it. Focus plays it once with no text, asks how much you caught, then takes it sentence by sentence and word by word until it lands. Tap a word to keep it for review. Prefer to just watch? Flow does that instead. Some videos have the subtitles burned into the picture. A normal player cannot take those off the screen. Reelang can. Hide them and you are only listening, not reading. Inburgering, the B1 route, the NT2 staatsexamen, KNM They come down to the same thing in the end: understanding real Dutch the first time you hear it, at the speed people actually speak. Reelang is not an exam course and sets no practice papers. What it gives you is the listening, hours of ordinary Dutch at natural speed, so the spoken part stops being the hard part. You're not memorising lists. You're hearing Dutch the way it's really spoken, fast, casual, alive, and understanding a bit more each day. That's when it stops feeling like homework. Free to start. Scroll, tap, learn. — — — REELANG+ (OPTIONAL) Reelang is free to use. Reelang+ is an optional upgrade that adds: • Learner insights on the words and phrases worth knowing in a clip • Word translations into your own language, not only English • A feed built around your interests • Vocabulary that returns in new clips, so it sticks Reelang+ is available as an auto-renewing subscription.
