Murph
Hey HN! I built https://withmurph.ai, an open-source personal health assistant to help you build healthy habits that actually stick. Everyone has something they want to improve, but it's way too hard to change your behavior. I've been using Murph myself for weeks, I've started a few sleep improvement experiments with Murph that've improved my deep sleep already, and run some challenges over group-text with friends. Murph has three key features 1) Talk to Murph on iMessage, Telegram, and Email and connect labs/wearable data 2) Run health experiments with proactive check-ins and…

What it does
Murph is a personal health AI that lives in iMessage. It referees challenges in your group chat or emails your family a weekly roundup of everyone’s health wins. It syncs any wearable, reads all bloodwork, runs health experiments on you to find what works for your body, and helps you build habits that actually stick. It can call the dentist, book DEXA scans, reorder supplements, and basically do anything you want for health. Open source, private by default.
Murph figures out what works for you—and gets your friends in on it. A personal health AI that runs experiments with you and challenges with your friends.
Wearables, bloodwork, doctor visits, supplements, blood pressure, sleep. Murph reads it all, figures out what actually works, and helps you build habits that stick. Start a health challenge with your friends, right in your group chat. Murph sets fair baselines, referees the week, calls the winner, and keeps everyone in the loop. Finish the sentence, for example: sleep better or feel more energetic . Habits stick when someone else is watching. Start a challenge with friends, or set up a weekly newsletter so the whole family knows how everyone is doing. Murph is the referee. It sets fair baselines across different devices, keeps score, nudges the slackers, and calls the winner at the end.…from withmurph.ai

HealthBuddy2025 · healthpalai.netlify.app · ▲9Hey HN, I built HealthBuddy because I was overwhelmed by conflicting advice on how to lose weight and get healthy. Between influencers, TikToks, and Reddit threads, it felt like more noise than clarity. So I created an AI-powered site where you can ask questions like: “How do I actually lose fat sustainably?” “What’s a beginner gym plan?” “What’s a decent meal plan for bulking?” “How do I stop late-night snacking?” “How much sleep do I need if I’m training?” It's built using GPT-4 with prompts tuned specifically for health, nutrition, fitness, and sleep. Answers are structured to be clear,…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
