Products that do what BabyStepsJs – Interactive Skill Tree for Babies in a Single HTML File does
Hi HN, I built BabyStepsJs to track the development of my newborn daughter in the form of a skill tree. It’s a mix of gamified documentation of her current progress and a bit of education on what she might discover next. I conducted a similar development experiment a few months ago with the same rules (see the cs-util-com/InstantScribe repo): - Act mainly as the PM and QA for the AI (this time ChatGPT-o1) and iteratively add user stories and requirements to extend the feature set. - Each iteration was typically a single commit, so the AI’s proposed changes were easy to review in the git…

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…

Hi hn, Its been a while since my kid has been dreaming to make videogames, as you know, the entry bar is high, too many technical details are involved. A few months ago, we started making games, we have tried many different ways, from dragging blocks to write code with a high-level library to make it simple, it is still too much work. Getting into the AI boat, I decided to give it a try for making games, turns out that it works super nicely, still, you still have many technical concepts involved, what language should the game be written in? where do you store the file/assets? how do you…

title basically covers it. project #2 from my paternity leave. My partner & I got frustrated with hearing Brahm's Lullaby and Wheels On The Bus repeatedly. I also stand by that babies can enjoy adult music just as easily as they can enjoy "kids music". But most adult music is too dense/complex for babies to understand, so I created this to generate baby-friendly, slowed down versions of songs that we like to play for our baby & sing along with. Uses BS-roformer for stemming out the input audio + spotify Basic Pitch for transposing to midi. Still needs some work, kinda sounds like a…

I built a library that lets you find code patterns using familiar CSS-like selectors, then connected it to Claude via MCP so AI assistants can understand and refactor codebases. The Approach // Find code patterns with intuitive selectors: const asyncFunctions = tree.findAll('function[async]'); const todoComments = tree.findAll('comment[text="TODO"]'); const reactHooks = tree.hooks(); // Built-in React support // Chain smart transformations: tree.transform() .rename('oldFunction', 'newFunction') .removeUnusedImports() .toString(); Key Features - CSS-like…

Hi HN! Solo developer here. 10 days ago, I started building this after spending countless hours copying/pasting marketing sections and fighting to keep them consistent with our design system. I wondered: "What if AI could understand our design system and generate React components that actually match it?" Current progress (10 days in): - Can generate hero sections that follow your design tokens - Uses your actual component variants and styles - Works with Next.js, Tailwind, shadcn/ui It's very early days, but I'm excited to share it with other devs who: - Are tired of rebuilding…

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…

I started an experimental series, "console.solve", on mini javascript challenges a few months back and received good feedbacks on it. So I created a [second one](https://colintoh.com/console-solve/issue-2?utm_source=colint...) this month. Not sure anyone here will be interested as it's not exactly pro-level stuff. But if you have an hour to spare, it can be a good distraction. For those who are interested, here was the [first challenge](https://colintoh.com/console-solve/issue-1?utm_source=colint...).

I built over 3-4 weeks to solve my own pain point, picking up rust along the way. It has a browser version that works online/offline and cross platform desktop as well. It was a pretty intense sprint. About TreeSnap, well it simplifies this preparation of sharing code with Chat LLMs. In my use case, making o3 via ChatGPT a lot more cost-effective to use for these tasks compared to Cursor: How it works: Select files/folders → generates a single text bundle + ASCII tree Instantly shows per-file and total token counts (list & treemap views) Quickly trim unnecessary files or folders to…

I built a CLI that detects patterns AI coding tools leave behind: empty catch blocks, hardcoded secrets, as any everywhere, comments that restate the code, god functions, SQL concatenation. 24 rules across JS/TS and Python. Zero config, runs offline, regex-based so it's fast. npx @yuvrajangadsingh/vibecheck . Also ships as a GitHub Action for inline PR annotations and standalone binaries (no Node required). Why: CodeRabbit found AI-generated PRs have 1.7x more issues than human PRs. Veracode says 45% of AI code samples have security vulnerabilities. "Vibe coding" is everywhere now…

I built Color with my wife Jessica, who is trying to break into the AI scene as a product designer. This is her first AI product, and she designed it from the ground up to be fun for non-technical folks who don't have any experience or interest in AI. There's WordMode, which is your traditional text-to-image image generation prompting experience. Then there's KidMode, where you create new coloring pages by selecting a series of image icons like "Bear", "Baseball Hat," and "Glasses". It's super fun to try with littles (2-5 years old), they love it. There's something magical about selecting a…

Hi HN, I’m César, a non-developer who started building prototypes using vibe coding (AI + prompts instead of code). While doing this, I realized a big issue: it’s incredibly hard to get a good design. Most sites end up looking the same. So I built Skilfut — a SaaS that provides a library of 138 UI components, each with its associated prompt. You can copy/paste them into your no-code or AI-coding workflow and get functional, styled blocks right away. Already 138 components available New components added every week (+200 planned) Designed in collaboration with designers from companies…

Hey everyone, ChatGPT recently added a very small but powerful feature - the ability to share your chats! I think it’s a great way to create prototypes and share them, here are a couple of examples: First, [a small talk simulator](https://chat.openai.com/share/1329d8ec-5141-45f9-a2c2-842d4bad7bcc) a game to help you improve your social skills. Second, [a shark tank simulator](https://chat.openai.com/share/48155efe-101b-4662-b41e-c13aa909f017), see if your idea and pitch can get a deal on ABCs hit show! [Here’s my…

I've created an interactive tutorial that teaches how AI models work. I set myself the goal of making it approachable enough that my 11 year old son Isaac can fully understand it. The tutorial aims to be easily understood by anyone who understands basic math, and yet give them a deep intuitive sense of not just how AI works but why it works the way it does. It does this using a series of interactive playgrounds that let the reader play with each idea. Currently there are 9 chapters, starting from scratch and ending with transformers. I'm planning to keep adding more chapters until the…

Hey, I'm absolutely thrilled to introduce my meticulously crafted Next.js Boilerplate, a project I've maintained for over 2 years. Recently, this project has achieved a huge milestone, over 4500+ stars on GitHub! Initially, I've build the boilerplate for my own use case. A template that allows me to kickstart a new React project with all the necessary tooling. The idea is to setup once and then reuse the template for all my future web projects, eliminating the need to start from scratch each time. This approach tremendously saves time, sparing me from repeatedly configuring and integrating…

I made https://girlgenerator.online My wife is an elementary school English teacher, and she often needs cute images for her PowerPoint presentations. However, finding the right images to match her themes can be quite challenging at times. So, I took it upon myself to help out with this task, and soon realized that searching for specific images could be quite time-consuming. I thought to myself, how great it would be to have a handy tool that could quickly and reliably generate the desired images. That's why I developed the Girl Generator, an AI-powered website that creates images…

I know vibe coding is controversial. I wanted to give it a try so over the last ~4 weeks I tried vibe coding a blender/houdini inspired node based 3d geneartion app in my spare time. The original goal was to try to generate great looking 3d environments from relatively small data. Most games download megs or gigs of data and that's no good for web based things. If you're an AI skeptic still, maybe seeing more concretely what's possible today might convince you otherwise? I'm not making any claim the code is good, though I'm also not claiming is bad. I had fun giving it a try. I was…

Hi HN, We're a small team building AI tutors out of India, and as you might guess, this means we spend a ton of time writing, testing, and refining prompts for LLMs. When we started out, we were using the OpenAI playground but things became tedious when we wanted to compare responses from different models. We tried a bunch of other playgrounds but found them lacking in some features so we built our own.
