Products that do what We just launched badges for Khan Academy does
Yesterday we added a brand new badging incentive system to the Khan Academy. It's really simple for now, round 1, blah blah all that jazz. We're dealing with all types of internal debates about proper behavior to encourage and how users will respond. We've seen students in schools get extremely excited about very, very simple game mechanics attached to their practice problems/homework/etc, and building the roots of a deeper badging system seemed like an important next step to help us guide users through desired paths in the system. You can check out all of our badges here…

Hi, I'm a high school teacher from Australia and I've built what I'd like to think is a pretty nifty ChatGPT powered presentation tool for teachers. I'd love it if you could have a look at it and give me some of your feedback. I don't think there's much overlap with the HN crowd and school teachers, but I've been coming here for many years and thought I'd post here and see what you all think. Check it out if you have a minute and I'd be super happy to hear your feedback too. https://www.slidehero.ai/ You can jump in and have a play with the tool all you like ;) Cheers, Eli

hi all, I've always wanted to make my own game, but couldn't afford a thousand-dollar adobe (flash+photoshop) license. I'm not a talented programmer, have no degree in CS. But I understand some elements of design. So I got me a copy of ImpactJS, and after about 5 months of steep learning curve (at least for me), I managed to come up with a game. I also integrated it with a highscore and badge system, similar to what you get at Kongregate. You need to login with Google/OpenID to earn badges/scores. link is: http://www.hotbazooka.com/privatejoe hope to hear some feedback/questions from you guys!

I love getting cool swag from hackathons and I also love designing PCB's, so when my friend asked me if I would design hackathon badges for a large game jam in singapore, I was absolutely down! The theme of overglade was a "The game jam within a game", pretty cool concept right! High schoolers from around the world were flown out to the event by hackclub after they spent about 70 hours designing their own game. These badges needed to be really cheap and simple, because we were going to manufacture about a hundred in a pretty limited amount of time. I went with a zero-power approach, which…

A few months ago (82 days to be exact!) I posted a link on HN to my game, Meatshields. A bunch of you commented and played my game and gave me some wonderful feedback. Over the last few months I've been playing with many of you and implementing the best of everybody's suggestions. So, thank you, HN for all your help! I feel this is an extreme overhaul I couldn't have done without your input. Since then, I have: Dramatically improved our hosting platform (So it HOPEFULLY won't go down this time (oops.)), Added two new units, Rebalanced all existing units, Added many more maps, Improved the…

I saw this app youlearn.ai on YC and thought of building it. They are claiming to have 1M+ users with just one feature which is to convert your learning material into summaries, quizzes etc. I gave this a shot and cloned almost most of the features in just 9+ hours of continous vibe coding (with 20% manual though). Now I'm selling this on mvp marketplace. Might probably open source it in future or give it free.

Hey HN, I’m a dev and a dad to a 10-year-old. I built this because I caught my daughter using ChatGPT to do her history homework. She wasn't learning; she was just acting as a "middleware" between the AI and the paper. The Backstory: I realized the problem isn't the AI—it's the zero-friction answers. Most "AI for kids" apps are just "parrots"—they mimic intelligence by repeating patterns. What’s Different: Qurio is a "Bicycle" for the mind. It treats the child like a future "Architect" rather than a "Junior Executor." Technically, it wraps an LLM in a strict "Socratic Loop." It detects…

I’m (re)building a tool to help elementary schools place students into classes (original app still uses jQuery… porting to React). Placing students into classes is kind of like a puzzle where the first kids are easy, but when you get close to the end, you realize your earlier placements need to be moved around endlessly. That’s why I wrote an algorithm to help. Anyway, teachers tell me it’s kind of fun, so I made a game out of it! This game simplifies the process a lot in the name of getting something that’s solvable by hand and playable on a smartphone. Hope you enjoy.

We did a "Show HN post" 6 months back of our startup and we're very excited to show everyone how far we've come as well as the lessons we've learnt so far! It's been a roller-coaster so far and we think there's lot more of the same to come! We did apply for Ycombinator funding but got turned down :( But may re-apply soon :) For those that don't know, our startup is called Scirra and we make Construct 2 which is an HTML5 game engine (http://www.scirra.com). Our engine allows anyone to make HTML5 games without knowing any programming. It's only me and my brother working on this and we're based…

hey all, happy to share research i've been working on for islo.dev in recent months. ever since the cheating agents (https://debugml.github.io/cheating-agents/) paper came out, revealing reward hacking was 4x more prevalent than previously estimated, i've been looking into how we can deal with the issue the common approach (taken by the tbench team) is post hoc trajectory analysis. i've been interested in the idea of reframing the problem as an endpoint security problem and tackling it via sandbox i hope you find it interesting, and thanks to the islo.dev team for…

Hi Hacker News! My friend and I [1] would like to share with you something we did this week-end. We really like the idea of game jams like the Ludum Dare, and we’d like to participate, but it’s often complicated for us, as we are often limited by the rules inherent to this kind of competition: we have to be available at specific dates, and the rules doesn’t always work for us. For example: if you want to participate as a team in a Ludum Dare compo, you have 72h instead of 48h, and you are not required to publish your code. We realized that what we really like is: - To work together. - The…

Hi Hacker News! My Co Co-op Matt and I are on a work term and were given the task of building a webapp that could make $20 in four weeks as our onboarding challenge. We're in the final stretch here and would sure appreciate HN's thoughts (we realize we kind of did this backwards, building something first before talking to people who might use it, but hey! We're leaning.). So basically, we tried to apply game dynamics to retaining visitors to websites by offering a reward (ie. discount coupon / premium content, etc.) for meeting various 'objectives' (ie. pages to visit). We call it ScavSite…

I haven't seen anything like this so I decided to build it in a weekend. How it works: You see a bunch of things pulled from Wikipedia displayed on cards. You ask yes or no questions to figure out which card is the secret article. The AI model has access to the image and wiki text and it's own knowledge to answer your question. Happy to have my credits burned for the day but I'll probably have to make this paid at some point so enjoy. I found it's not easy to get cheap+fast+good responses but the tech is getting there. Most of the prompts are running through Groq infra or hitting a cache…

Hey, A bit of context.. So I think last week was my last straw, I hit 8k hours with dota and holy ** It finally hit me how much time I wasted on that game. I'm a software developer, I always wanted to develop something and put it out but was scared shitless to do so, I was kinda afraid to get bad traction, to fail or even worse to be completely ignored. so I decided to address two of these issues at once, stop playing dota and spend the weekend building a website that let you see what you could've done with your gaming hours. As an avid gamer for the last 20+ years, I know that it's only…

This has been my secret pleasure for the past four years. Ever since I started playing D&D during the pandemic, I discovered my love for role playing and storytelling, but Beyond just wasn't cutting it for me. I wanted to make my own personal character creator and tracker that I could use for my games, so I set out to build Dwarven Academy (https://dwarven.academy/) and after two years of learning I decided to rebuild it all from the ground up, so The Elder Dragon's Tavern was born. Try it out at https://elderdragonstavern.com/ This is an app to build and track…

I wanted to learn more about RAG implementations, so I built something to solve the constant digging through manuals whenever we play a game. It's fairly simplistic, but actually has worked pretty well for some of these conflicts. Everythings Open Source on GitHub if you're curious (or have ideas), and I'd love to hear feedback from fellow boardgamers!

I've been experimenting with ways to increase AI adoption for non-technical people. Basically, all companies are pushing for AI because it's all over the news and they feel left behind but most people have no clue where to start. I think 90% of people (ie non coders) are sufficiently well served by using cowork instead of claude code or something similar. If we can get people from sales, customer support, marketing, etc to collaborate with skills and cowork to form a company brain, I think it's gold. So I think there's opportunity for the community to share skills that work well for 1000s of…

I had an idea for this concept for a while and decided to build a little website around it. It's kind of a silly idea but I'm really curious to see how it plays out. If you're a particularly curious person, be warned. By submitting a payment to the game, you get to see how many other people were curious enough to play. You will be ranked based on your payment amount, and get to discover some interesting insights about the game's dynamics. Hope you like it

Hi HN, I built AgenTank. It is a small game where an AI agent writes the logic for your tank. You watch it fight, give strategic feedback, let the agent update the tank code, and send it back into battle. I have run 1,000+ battles on my own tank and spent about $200 in Claude credits improving it. The part I enjoy most is not just winning, but watching the tank make visible mistakes, thinking of a better strategy, and seeing whether Claude can turn that into better code.

Hi everyone, I just saw a vibe coded game on HN, and thought maybe I should post about this here. I'm organizing a vibe coding game dev competition called Vibe Jam. Last year we did it too and there was 1000+ games submitted. This year the deadline is May 1 and you can submit your games until then. There's $35,000 in prizes with the Gold prize being $20,000. Let me know what you think! -Pieter

I got tired of posting on r/fitness and getting unclear feedback, so I built an app that analyzes physique photos with AI. It started as a weekend project after I couldn't get good advice on my lifting progress. Upload a few pics and the AI tells you: Where you rank compared to others (using a gaming-style tier system) Scores for each muscle group with actual numbers Body proportions and balance issues Body fat estimates and body type I also added some fun stuff like matching you to a "warrior type" based on your build (turns out I'm built like a Viking, not the Spartan I was hoping…

Over the past three months, I’ve been working with my dad on this app as a way to learn Cursor, shadcn/ui, and Next.js. I’m currently studying UX design at the University of Michigan, and I’ve been really impressed by how much vibe-coding tools have advanced over the last six months. This work journal includes private AI-generated insights with scheduled summaries that can be shared with your team or manager. You can also choose to make a summary public—like I’ve done here for my work on this web app: https://www.workjourney.ai/summary/mkblt2zt-hn2kdbus If anyone has…

I started giving away badges on X to people who touched grass just for fun and most of them loved it! So I decided to create a whole website about it. Process is simple: - Enter X username / url - Fetch Profile image and choose badge - Generates a badge page which can be shared with nice OG images The site is deployed on Vercel, with R2 and Browser rendering for OG images and data storage.

Hello, This is something I've wanted to build for awhile (first bought the domain in 2020 (then lost it for a year+)). It's a tactics solver on each new tab page. There are 5 modes of play: Easy (<1200 elo) Medium (1200-1800) Hard (1800-2400) Expert (2400+) Speedrun (solve as many puzzles as possible in 60 seconds). I'm having a ton of fun with it, and definitely noticing improvements with actual games (definitely solved the most puzzles in my life while developing this extension). If you check it out, please let me know what you think. Any feedback is good!
