Launch HN: Univerbal (YC W23) – Language learning with a conversational AI tutor

#1
Hi HN we’re David, Sam and Philipp and we’re building Univerbal (https://univerbal.app).

We’re an AI language learning app where you talk to your AI Tutor, just like you would with a human one. Here’s a short demo of what that looks like in an actual conversation: https://www.youtube.com/watch?v=IukKGc00juY

We actually started as a Show HN over a year ago and the responses we got from the HN community led us to apply to YC and make an actual company out of a side project (original Show HN https://news.ycombinator.com/item?id=32993130). We were called Quazel which we have since realized is too hard to spell and only makes sense in German.

We started off as only offering open-ended conversations. While that is still at the core of what we do, we quickly realized that we need to solve a bigger problem for learners than simply giving them the option to hold a conversation with an AI. Tutoring is (usually) the highest quality of education you can get. The curriculum is based on your interests and needs, you move at your own pace and you get personalized feedback about your specific mistakes.

At the same time, the reality is that tutoring is prohibitively expensive for most people, let alone that it can be very time-consuming to find a tutor that you like and you have to work around their schedule. We want to fix these issues by providing an AI Language Tutor that’s available whenever you want and affordable to everyone.

Now the tricky thing about this, is that a human tutor (to no one’s surprise) actually does many things at the same time, which are very much not straightforward to approximate, even with AI. The interaction part of a tutor session is already the main interaction in Univerbal, through speaking and having the replies read out loud. The hard part intervenes when you try to replicate the progress tracking and tailoring of the curriculum.

These are things that tutors automatically do, and getting a system, even one that’s based on LLM to do something like that is very hard! Our current approach is based on “Skills” (e.g. I can introduce myself), that a user works towards. These are a measure of where the user currently stands and we use this progress in a feedback loop to come up with relevant and interesting next lessons for a learner.

I often get asked, “Ohh so is it like Duolingo?”. When I get that question, I smile, feel something inside me die and then say that, while Duolingo is a great language-learning app, we don’t really see them as our competition, rather we see online tutoring platforms (italki, verbling, cambly etc.) as the companies we’re “attacking”.

We already have a couple of success stories. One of which comes from an Australian user who’s living in Italy and has successfully prepared herself for her Italian B2 language exam by using Univerbal :). If you’d like to give it a try, you can try it without an account for free for 7 days (no credit card required). Afterwards, it’s about $10ish/month.

One thing I’d love to get HN’s opinion on is how much gamification you think we should add. On the one hand, we don’t want to become a “game” and a Tutor lesson is always a “hard” thing and kind of exhausting, but there is obviously some balance to be struck there. Thoughts?

This looks really cool, for sure I will to try this out ! I will look into it for Italian.

I'm not sure how much work is it for you guys to add a language, maybe it's easier for you to add languages than for other mainstream platforms thanks to the use of AI ? If it the case, it would be really nice to have one serbo-croatian language, such as croatian or bosnian.

I struggled to find ressources for these languages. Since a few months I have been trying to learn Bosnian (going on a long trek in the balkanies this summer) and I was just not able to find any "modern" service (Duolingo, Babel, etc ...) which supports these languages. I guess it makes sense since almost no-one wakes up and decide to learn Montenegrin, but maybe you can find a niche market.

Anyway, cool product ! I hope you guys make it.

even though the AI might know some of that language, it will probably not be familiar enough to basically never make a mistake. Another problem is that speech recognition, Text to speech and the translator also need to work in that language.

I like it (was actually just thinking about a bot like this after seeing a related submission on hn yesterday).

Bit of feedback: the UI confused me when it asked for what language I want to learn. I didn't realize the flag was a button to choose my language and spent a little while in two different browsers thinking the space next to the microphone was a textbox to type in or the microphone was the button for letting me talk. For some reason "use the buttons above to continue" didn't make any sense to me until now. Maybe cause there was only one button?

Anyways, I don't use a lot of apps and when I do I often find the UI to be confusing, so I might be an outlier here. But I almost gave up and didn't try it.

Good luck!

Yep, I agree that could be made clearer.

I really like it!

It worked the first time after asking for mic permission.

But second time, I did have a problem with the mic button on iOS 16.6.1 getting stuck on but not taking audio input.

Pushing the button again (to cancel perhaps) did nothing.

Switching to tutor mode fixed it for another input.

Couple things, all reported from Android Chrome:

1. The FAQ on the landing page hides questions as answers are opened, and it is not obvious that previous answers need to be closed to see everything.

2. On the FAQ page, when opening the hamburger menu, the menu is clipped and must options are hidden.

3. The FAQ question about pricing does not answer the question, and I see no where to get an answer.

4. Re: gamification, I think it is enough to reward users with making progress, and encourage them to use all the different kinds of modes/ features.
