MediNAVI JAPAN
MediNavi JAPAN is a multilingual healthcare navigation platform for international visitors and students in Japan.
The project was inspired by real challenges I encountered while working as a nurse at a clinic in Japan. Patients often struggle to identify the right medical specialty, find a nearby clinic that supports their language, or understand whether the facility is currently open and accepts walk-ins.
MediNavi JAPAN helps users search for appropriate medical facilities by symptoms, specialt

Show HN: I rebuilt Microsoft Comic Chat's layout engine in one HTML file
I used Comic Chat in 1996 and never got over it. So when Microsoft put the source up last week, I wanted it back the way I remembered it: same engine, browser tab, no install, works on a phone.I do not write or read code. I'm the proverbial "product manager." So, I have to thank both GPT 5.6 and Fable 5 / Opus 4.8 (just before they released Opus 5 today). I aimed to stay faithful to the original as much as I could and extend it intelligibly.It's not IRC, but you can conn
Show HN: ScreenFocus – keyboard focus follows the pointer across Mac displays
I have a multi-monitor setup and spend a lot of time typing in Codex and other AI agents. When I move to another monitor to run a shortcut, focus often stays in Codex or another text app, so the shortcut runs in the wrong place.I asked ChatGPT if there was a macOS setting or free app for this. It couldn't find one that did exactly what I wanted, so I asked it to prototype one. It built a working version in one go.I then used Codex to add sensible defaults, focus protection, an optional disp
Ask HN: HotPin – lossless 120B MoE inference on 24GB RAM (CPU, 50 loc)
I'm a mechatronics designer with a background in control systems, robotics, PCB design, and embedded hardware. I design physical systems: motors, sensors, microcontrollers, and real-time control loops.I applied this design thinking to LLM memory management – and it worked.HotPin is a set of patches for llama.cpp that runs 30B–120B Mixture of Experts (MoE) models on far less RAM than their disk footprint, with bit-identical (lossless) output.Tested on an AMD Ryzen AI 9 HX 370 (Zen5, AVX512),
Ask HN: Which is the least sloppy and claudeism free model you have used?
I feel like recent models have been consistently getting more sloppy and increasingly claude-ism heavy (load-bearing seams galore) with every new release.I was hoping this trend would reverse in newer major version releases but I just tried out Opus 5 and it's similarly shit at writing. Fable is slightly better but not by far (and of course ridiculously more expensive). Adding skills helps but only mildly and not much at all for longer prose.Have you guys used any model lately that you like

Show HN: Mumble Dictation – local dictation that learns your vocabulary
Hey HN! It’s Wen from Narya.ai. We build Mumble Dictation, a local-first and privacy-focused dictation app on Mac.Homepage and Download: https://heymumble.com/dictationYouTube：https://youtu.be/Bma59TrR62c?si=DM-LyjZY5GZ9-f64Two things kept bugging us about the dictation products on the market:1. Most of them ship your audio to the cloud, and those who is claiming to be private are often just a thin wrapper of cloud APIs with a privacy policy.2. Those general-purpose
Show HN: CobaltCode – Dedicated persistent computer for Codex
Hi HN,I'm building CobaltCode, a platform for running coding agents inside persistent development environments.Basically I was fed up with git worktrees and having to run everything locally, usually one at a time so built CobaltCode.ai. Each task gets an separate vm with its own repository checkout, dependencies, running services, agent session, previews, and persistent state. It can also run your app inside the vm so you can preview different features in parallel.You can leave a task, resu
Show HN: Agent in 9 Lines Python
I asked myself: what would a minimal implementation of an agent look like?Something that works out of the box, is a real agent with tool calling, but without 1000s of lines of code, without dozens or hundreds of npm or pypi dependencies. Something with just a few 'essential' features (not a whole kitchen sink that most agent harnesses come with nowadays).An implementation close to pseudocode that you can look at in one page, everything there at a glance, no scrolling.This is the agent.
Show HN: Millwright – Rust-based, self-hosted LLM router
Hey HN,With the news of OpenRouter possibly being acquired and proliferation of hosted LLM routers (i.e. Ramp Router, Vercel’s AI Gateway), I saw the need for a self hosted solution focused on cost savings, transparency, and performance. So, I built an open sourced router with a simple CLI interface that can easily sit between coding agents and GenAI workloads.For the curious and lazy, at the moment, Millwright has the tools for,- Providers: OpenAI-compatible APIs, Anthropic, Amazon Bedrock- Rou
Show HN: Use your flight-sim gear as a Codex Micro
When I saw the OpenAI Codex video for the (cool-looking) Codex Micro, I looked down at my Virpil CM3 throttle collecting dust.So I just asked Codex desktop to connect it for me-- and it turns out the latest desktop app has the hotkeys/bindings defined for the Micro already. In a couple of hours I had the core options bound and over the weekend I got to full LED status control.The code is Windows stuff and probably not the hardware you have on hand, but that almost doesn't matter anymor
Ask HN: What do you do when your AI agents are working?
Maybe a dumb question but I don't think I've ever experienced more down/waiting time in my career so I'm much more prone to opening YouTube, HN, etc. despite not really wanting to.<p>Most likely the answer is to just sit and do nothing. But have you discovered an approach to making agentic coding, etc work for you without feeding into distraction and attention deficit?
