24 alternatives to Open-source tool for creating courses like Duolingo
I'm launching UneeBee, an open-source tool for creating interactive courses like Duolingo: GitHub repo: https://github.com/zoonk/uneebee Demo: https://app.uneebee.com/ It's pretty early-stage, so there's a lot of things to improve. Everything on this project is going to be public, so you can check the roadmap on GitHub too: https://github.com/orgs/zoonk/projects/11 I'm creating this project because I love Duolingo and I wanted the same kind of experience to learn other things as well. But I think this could be useful to other…

UneeBee▲13I built an open-source tool for learning anything using AI: - Type what you want to learn - It creates a full interactive course for you Move from beginner to mastery of any subject, even complex things like Quantum Physics It has three formats: - Explanation: bite-sized lessons that you swipe like TikTok/Instagram - Practice: solve problems in real-world situations - Quiz: test your knowledge in Duolingo-like lessons - Language courses have a different format covering vocabulary, reading, and listening skills It's more hands-on than reading a long textbook or watching a video Plus, it…

The idea is actually quite simple. As a Japanese learner and a coder, I've always wanted there to be an open-source, 100% free for learning Japanese, similar to Monkeytype in the typing community. Unfortunately, pretty much all language learning apps are closed-sourced and paid these days, and the ones that are free have unfortunately been abandoned. But of course, just creating yet another language learning app was not enough - there has to be a unique selling point. And then I thought to myself: why not make it crazy and do what no other language learning app ever did by adding a gazillion…

Hi HN, I watch A LOT of educational YouTube videos but wasn't forgetting a good chunk of the details because I was only really passively watching. So I made a tool that generates quiz questions/flashcards from YouTube videos, and uses spaced repetition like Anki or Duolingo to keep it in memory. Let me know if you find it cool/useful (or terrible ) or if you want to know a bit about the details!

I've been working on a little side project that combines Duolingo-like listening comprehension exercises with real content . Every video is transcribed to get much better transcripts than the closed captions. I filter on high quality transcripts, and afterwards a LLM selects only plausible segments for the exercises. This seems to work well for quality control and seems to be reliable enough for these short exercises. Would love your thoughts!

Hi! Wanted to share the project I really wanted to have. TLDR; this app lets you create your own list of words and you get a Duolingo-like experience (kind of, still needs a lot of features) practicing those words in their context. My English is not the best but not the worst either. But I realized I can't boost it up after a certain level! In my belief, in order to truly learn a language, you need to be exposed to that language often. Vocabulary is the key factor here if you really want to improve in any language. My experience is that when I read a book to improve my English vocabulary, I…

A few years ago, right after high school, I decided to try to make a simultaneous translation app for Android as a side project, it took longer than expected (about 2 years) and I had to make a lot of compromises (I had to use Google's API and therefore make users use a developer key because at the time there were no free solutions for speech recognition and translation that had good quality). At the end of university, I decided to pick it up again and finally, using OpenAi's Whisper for speech recognition and Meta's NLLB for translation (with both running locally on the phone), I managed to…

Inspired by the design and UI/UX of apps like Notion, and utility of open-source apps like StackEdit, I decided to create a minimalistic, local-only WYSIWYG Markdown editor. Some features worth highlighting: - Monaco editor and Prettier integration for code snippets - Tables (apparently the holy grail of WYSIWYG editing) - Embeds (for CodePen, CodeSandbox and YouTube, most useful for HTML or JSON exports) - Accepts Markdown paste-in, and "exports"/generates HTML, Markdown and JSON outputs - Collaboration (with real-time awareness and initial commenting system, available only when…

Hi HN, For over two years I've been working on an App to learn languages (currently French, Italian and Spanish), together with my partner, a language teacher. I think it is finally ready to share with this community! The idea is to introduce vocabulary and grammar whilst you read eBooks in your own language. I've found that it is easier to remember vocabulary 'in context' and with regular repetition. Plus you don't have to carve out dedicated time for language learning. Other apps require you to build a habit around various exercises or ‘games’, whereas lots of people already read books.…

Hi HN, I’m Pablo, I built this application to learn languages using podcasts: https://www.langturbo.com (No signup required) There are a lot of tools to learn languages, but most of them focus on beginners (understandably so, that’s where the money is) but not many exist that target intermediate or advanced learners. The ones that exist make you find content on your own and then import that into their apps, which can be tricky when you don’t know where to look. LangTurbo has a unique curated database of podcasts by language (some even have dialect labels) that you can browse by…

Hi Everyone, I recently wanted to learn Japanese with duolingo but it kept giving me repetitive lessons. So I built an app that gives a variety of lessons from anime. You can try it out here:https://kanjieight.vercel.app/ Thanks everyone.

Hey there! Out of the necessity to teach my son a new language, I developed an app just for him. After months of use and realizing how effective it was, I decided to make it available to the public. Now, I’m looking for your support, feedback, and possibly help in reaching potential customers. Take a look and let me know your thoughts! Thank you!

As hard as I tried, I didn't find a modern language learning book that's either very academic, or like "master a language with my super-magic great method in 3 months". So I dug into the academic research, tried many techniques myself, saw what worked, wrote a book for learners of any language and any level, and made it free without ads. Today, finally, a 2 years-long project ends. I hope it helps anyone. Book's here: https://thehardway.guide/ Cheers

Here is a tool I built initially for myself to help with my German and Greek language studies. It started as a hack for creating Anki cards from native language audio. It extracts the words, finds their base forms (lemmas) and groups the examples by the lemma. At some point I realised that I have a transcription with word level timestamps that opens a lot of other opportunities. So I added a mode to click the first and last word in the transcript and it starts looping with the right gap and repeat count. Another feature I use a lot is selecting an audio fragment, sending a predefined prompt…

Recently moved to Egypt, and in dire need to get the numbers down. Great excuse to explore learning software some more. Possibly very niche, but maybe it is useful for someone else out there. Feedback is always welcome.
