Products that do what I am relaunching the app I made to talk to my Danish girlfriend does
It has been a while since I have shared my app, that I made to be able to practice my Danish while chatting with my grilfriend - I often used GPT to write as much as I can in Danish, and I replaced the words I didn't know with {Englis words in curly braces}. While this was great, it was rather annoying to type the prompt always, so I figured a GPT wrapper would work well here. Last time when I launched, it went viral! I was super happy (and grateful!) for all the feedback and excitement — but it also meant my tokens disappeared fast, and many people ended up trying an app that no longer…

I'm in my 4th year living in Denmark as an expat, and I finally decided it’s time to properly learn Danish. I do have a Danish girlfriend, after all. One way I’ve been practicing is by trying to text only in Danish, but I often find myself stuck. I start my message in Danish, then hit a wall because I don’t know a word or how to fit something naturally into the sentence. Especially in those cases, I used to give up and translate the entire message from English, which kind of defeats the purpose and interrupts the learning process. So I started prompting GPT. I’d write my message with…

Hi guys, Hope everyone is well. This app was borne out of my own frustration. I thought that I was terrible at learning languages at school, since I didn't become conversational in French after 5 years of study. However, I later traveled with some French friends and, in just under 3 weeks, I was able to hold a reasonable conversation. I realized that there's no substitute for speaking to native speakers. I tried to adopt this approach for other languages, but it's much harder to find people to practise with when you aren't travelling. I started using iTalki to meet people from different…

I’ve been using this for my own workflow and friends suggested I share it with them so I quickly threw together my first chrome extension! As an ex-editor, I think chatGPT is overlooked as an editor with everyone jumping straight into writing. Editing is essentially giving it as comprehensive a writing prompt as possible. Playing with the actual prompt also gets you a wide range of different results that grammarly/other apps cant really do. The x% has been changed tool was the first thing I built to see how intrusive chatGPT's editing was at a glance. My biggest struggle was trying to…

Hey everyone! I’ve been learning the Russian language on and off for over 15 years now. I took classes in college, and of course continued my education through apps like Duolingo. I started learning the language because one of my closest friends growing up was Russian, and I thought it would be cool to be able to speak with him in his language. Of all the ways I’ve learned the language, not one of them focused on the modern way we communicate: through text. I decided to make this app to create a text-first language learning experience --mostly so I could keep up with my friends’ groupchat.…

Hi everyone, I’ve been using ChatGPT to analyze my journal entries and to reflect with. It works great, I really liked it. I’ve managed to gain some good insights about myself and made improvements. However, there are a few problems: - ChatGPT only remembers key facts about you, it has limited memories - ChatGPT couldn't recall the content of conversations you had with it - For individual ChatGPT products, your private conversations might be used to train future models (see: https://help.openai.com/en/articles/5722486-how-your-data-is...) So, I decided to build my…

I moved to Denmark from Russia two years ago. I noticed that it's hard to learn Danish while living in Copenhagen because everyone speaks good English, and it's hard to find friends when you don't speak Danish. I joined a public language school because it's free to study Danish for the first five years of residency. I didn't learn much because, apart from this public school, I didn't have anyone to practice Danish with. I've created an app where you can speak with friends you already have, and you can all learn different languages because the app will translate it for you. You can join the…

Hi HN, I built Lengpal, a simple language exchange platform where two people get instantly matched on video to practice their native and target languages. There’s a timer built in so both sides get equal time to speak. I created this because I wanted something beyond passive apps like Duolingo. Something to actually speak with real people without the hassle of scheduling or chat fatigue. Right now we are testing the concept with a waitlist. We’ve collected 77 emails so far from Reddit and IndieHackers. I would love your feedback before launching the MVP. Site:…

Hey HN! Halfway through moving to Canada and whilst my conversational French gets me by, I'm absolutely rubbish when someone rattles off phone numbers at full speed (quatre-vingt-dix-neuf anyone?). So I built a virtual pet that thrives on correctly answered number challenges. 20-second drills throughout the day: get them right and Lexie grows, get them wrong and it gets a bit sad (but never dies, this isn't the 90s). Speak, type, or tap your answers. Would love any feedback/bugreports. Or just rant about how the Belgians sensibly say "nonante-neuf" whilst we're stuck with…

Hi friends! I've been waiting for ChatGPT Code Interpreter access for so long that I decided to just build my own. I figured maybe some of you are in the same boat so decided to do it as an Open Source project.

Just for fun I decided to see if I could use chatGPT to solve NYT Connections word puzzles. It uses a pretty straightforward BFS search in which the LLM is first prompted to generate several possible groupings of four related words, and then a different prompt is used to evaluate the soundness of each of those groupings. This approach seems to be able to produce the correct solution somewhat less than half the time. Some observations: * For whatever reason, chatGPT-4 seems to be a bit worse than 3.5 at generating Connections groupings. I haven’t tested systematically so maybe this is just…

So I've been obsessed with a weird question for the past 6 months, what happens to SEO when everyone starts asking ChatGPT for recommendations instead of Googling? The answer, apparently, is chaos. And maybe opportunity? I built FirstClick because I noticed something strange. My previous startup was getting zero traffic from AI assistants, but our competitor (objectively worse product, sorry not sorry) was getting mentioned by Claude and Perplexity constantly. It drove me crazy. So I reverse engineered why. Turns out there's a whole new game being played and most founders don't even know it…

So, after many years of kicking about little apps and not putting the full effort in, I decided to bite the bullet and get on with it. Very much inspired by patio11 and Bingo Card Creator, I present Griddol (http://www.griddol.com) a tool to create and play word searches. Intended mainly for teachers, but encouraging those who like a word search too. This been churning around in my head for over a year in various forms, and I used the concept to help learn CoffeeScript, CouchDB and node.js, so even if the product itself is a failure, the learning process has been valuable. I'll be the first…

Hello there! I hope you're doing well today! I wanted to share something with you. Recently I was on the hunt for the best way to journal daily. Well, I had this idea - what if I could feed all my daily entries to an AI (ChatGPT), and create a friendly, supportive character like Socrates or Simon Sinek? This way, I could ask any questions about my life and mental health, and get some amazing advice on how to improve myself! The results have been absolutely mind-blowing ! I even made a short GIF to show you how it works - check it out! - https://gifyu.com/image/SdHLH I've…

Hi HN! In the last couple of weeks I've been working on Cranki: Cranki = Crosswords + Anki. (It's a stupid name tbh, haha) I like doing crosswords in Spanish (to learn vocab) but none of the apps out there allowed me to use my own list of words that I come across. So I built one instead. It's entirely client-side. No server, no database, no accounts, etc. Your words and stats are stored in local storage. I built this for myself but let me know if you like it!

Fun project I made over the weekend to ask AI Chad any questions you many have. Leveraged "developer mode" with the new chat api + next.js. Originally made to show my friends, but some people here may get a kick out of it. Share any good Chad answers you get!

Hi guys, For my startup at www.mithrin.ai which is about create AI Chatbot Agents for websites, I wanted to create some free tools to attract traffic to the site and decided to create specialized chatbots powered by LLMs, similar to OpenAI's Custom GPTs. I realized that by using gpt-4o-mini, I could create quite powerful alternatives to GPTs that are free to the public for a very small cost (given how cheap the model api cost is). I've employed some throttling to prevent abuse and to avoid being charged too much. Then I integrated this with my main service and allowed users to use the…

Happy Valentine's Day! I built a language learning app designed specifically for couples, where one partner helps the other learn a new language in a fun, personalized way. My partner is originally from China, and I wanted to learn Mandarin and Cantonese to speak to her family. But learning through other apps, I found many words sounded awkward or outdated — especially due to regional differences. I wanted to sound natural and local, not like a textbook. Instead of struggling alone, I thought why not learn together? Many of my couple-friends were in the same boat but had no real system and…

Hi HN, I have been studying languages as a hobby for a large portion of my life. Hence, I decided to create a spaced repetion app with the techniques that have helped me the most so far. It's aims to be made simple for the regular user to plug and play. I'd love to hear your feedback!

I was frustrated with how I share ideas online. LinkedIn/X forces you to compress everything into hot takes. Research papers require months of work. And posting on social media increasingly feels like trying on outfits in ChatGPT until you find one that "fits" – performance over genuine thinking. I wanted something in between. A place where: - Half-formed ideas are okay - Thinking evolves over time (with revision history) - Garbage gets pruned naturally through format itself and status tracking (exploring → resolved → abandoned) So I built Kwegg. How it works: 1. You're in ChatGPT or…

Hi there! I made this tool called Finish UP to help me do exactly that with my personal projects and work tasks. I found that I had a few problems that cross-cut the majority of my projects: 1. I have loads of new ideas for projects, or tasks to do like learning German, but I do not always know where to start 2. I open a kanban board and then do not know what type of tasks to start with, how detailed they should be, or to what extent they can overlap 3. I started using ChatGPT and equivalents to help me ideate and put in place initial plans, but as soon as I asked questions about certain…

Hey HN! As I sat to write my 2025 reflection, I realized one thing I was missing was a ‘year wrapped’ for my relationships — I got my music, got my photos, got my fitness wraps — but what about my relationships? Specifically, I wanted to figure out what my text conversations say about my relationships and myself, and if there’s been evolution throughout the year. Who reaches out more? What’s our tone and conflict resolution? What were our month by month successes and conflicts? So I built an app that analyzes WhatsApp conversations (.txt files) and surfaces the patterns — using Anthropic’s…
