TL;DR: I built a web app called LangGlitch that aggregates comprehensible‑input videos (and soon podcasts/graded readers) for multiple languages, starting with German, Vietnamese, and English. I want it to become a one‑stop place for comprehensible input for every language, including small/obscure ones, and would love your feedback and language requests.

Hey folks, I’m Stefan, a guy from Germany who loves travelling and getting lost in new cultures and languages. In school I was terrible at languages and grammar never really made sense to me, but at some point I realised I had somehow become fluent in English just by playing games and watching YouTube in English.

Looking back, what worked for me was basically “comprehensible input”: content that I mostly understood and actually cared about, consumed for fun rather than as “study”. These days I always try to learn new languages that way, but I kept running into the same problem: unless you’re learning something huge like Spanish or Japanese, good comprehensible‑input content is scattered and hard to find.

So I decided to build something for myself and ended up turning it into a proper project: LangGlitch – a little web app that aggregates comprehensible‑input videos for language learners. Right now it supports German, Vietnamese, and English, with playlists grouped by difficulty, tags, and creators. You can sort for “easiest”, filter for topics you like, and then just watch your way through material instead of hunting for the next decent video.

I’d love for LangGlitch to eventually cover every language out there, including the really small and “obscure” ones, so it can be a genuine one‑stop place for comprehensible input. If there’s a language you’re passionate about and want to see added sooner rather than later, tell me in the comments or message me and I’ll do my best to prioritise it.

I’ve just put it into free open beta, so anyone can sign up and play around with it. I’m planning to add more languages over time, plus podcasts and graded readers, and if it ever makes enough money to pay its own bills I’d love to commission new comprehensible‑input content for underrepresented languages as well.

If you try it, I’d really appreciate honest feedback: confusing UI, missing features, annoying bugs, anything. You can leave comments here, DM me, or join the Discord (linked on the site) and yell at me there. Screenshots in the comments so you can get a feel for how it looks.
