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 discover what protocols improve your health. 3) Run health challenges with friends inside group-textsSome other things our users are doing: - help manage chronic pain and track what causes symptom flareup over iMessage - watch calories and protein intake every day by sending voice memos/photos of meals - find workout insights in mountains of lab and wearable data - build a physical therapy habit to improve lower back pain - improve RHR with targeted sprint routinesI hope that Murph can make building a healthy lifestyle more easy and fun for some of you :)Happy to chat about the AI or stack behind the product (uses codex cli under the hood). Let me know if you have any questions/comments/feature requests!
