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.
Wow, thanks for the amazing feedback! This helps a lot!
Your concerns about the Landingpage are valid & yes its pretty much a layout copy of cjjapanese. I myself am not very good at marketing & design so that’s why I just started with something that already works. The Landingpage will get a full redesign after some feedback (I will for sure highlight the currently available languages!).
On your thoughts of the infinite scroll, I understand your sentiment but I think this is also highly subjective. I could probably add a setting or something similar that changes form infinite scroll to paging but that would be a pretty low priority at the moment. I’d rather improve the infinite scroll in away that it isn’t annoying, so would it be better to not load randomly & order them by Difficulty as the default option?
A Watch-Later option is something I will do for sure but its also not the highest priority but a nice feature that will for sure come.
The Tag loading problem might happen because I didn’t scale up the server very high at the moment for cost saving reasons during the test phase. This should resolve itself when I scale up the Server & databases at a later point. I agree that there are a lot of tags but there are also a lot of different Videos on the platform already & they will only expand. Maybe I can consolidate some at a later point & remove the ones that only have very few videos.
I like the Calendar progress tracking suggestion. I will add that!
Hmm, I see your point that you could just use my platform to discover the Videos & then watch them on Youtube but that is a general problem I guess. But what the platform is offering isn’t necessarily the content but aggregation, discoverability & curation and some people just might not value that. So if I offer unlimited watch-time in the free tier it might not be sustainable as a business because Progress tracking alone isn’t a selling point in my opinion. The problem on the Free tier also would be that it would be Ad-supported & that doesn’t really make a lot of money unless you go overboard with them. Currently you make $0.00025 to $0.002 per banner ad impression which isn’t a lot & I only planned to add some ads into the Video browse page & a small banner into the Videoplayer so I don’t think I would be able to recoup even only the cost on a free tier user. But nothing is decided yet so I might just have to go with it anyway to get people to use the app.
Yea subscription fatigue is a huge problem right now, especially for SaaS businesses. That’s why i would probably aim between 2-4$/month for the premium version. Also Dreaming & CiJapanese are for sure competitors but only in one language so I think there is still a lot of value in my Service. Also I don’t see the free Youtube Videos as a big competitor because the core of the business isn’t the content itself (not yet at least, I hope I can produce some later).
