Lost requirements, unfinished tasks, and unsupported completion reports: a look at recent Codex complaints, official incidents, and the difference between intelligence and reliable execution.
What began as a Japanese translation of Human Atlas is now JINTAI 3D, with Z-Anatomy models, peripheral nerves, quizzes and experimental joint motion. But most of my time now goes into checking whether the names and explanations are actually correct. Part 4 of the series.
I use a Notta Memo, so I lined up its official specs against the PLAUD NOTE Pro, NotePin S and Soundcore Work. Recording hardware versus what happens after you record, and which one fits which job.
BodyParts3D, published in Japan in 2009, was found by a Belgian medical illustrator, rebuilt in Blender, and grown into Z-Anatomy by engineers and translators. Then in 2026, an AI post on X led me back to it. Open source isn't free stock: it's a relay of other people's work. Part 3.
For healthcare professionals who want to build and sell teaching material, courses or apps with AI. Buying the book does not make it free to use. How to check input, generation and publication separately, why citing your source is not permission, and the option of building it together with the author.
GPT-6 Astra is here. For people working in healthcare, I dug into what it is actually useful for, in the form of an interview with Astra. Not just naming diseases: paperwork, comparing papers, explaining things to patients, and teaching material built on the spot. Published performance, research on other medical AI, and future ideas are kept separate.
A 3D human body you can pull apart in a browser. I went looking for who made it and how, and ended up at BodyParts3D, published for free by Japanese research institutes, and TARO, a body model built to study mobile-phone radio waves. Part 2 of two.
A 3D anatomy viewer scrolled past on X, built with GPT-6 Astra. I localised it into Japanese and put it on Cloudflare instead of Vercel. The question it left me with — who made the underlying body data? — is Part 2.
The same 10% of take-home pay weighs differently for someone living alone in Tokyo and someone living with family. Using Japan's household and housing surveys, I generate a standard household for your family size and prefecture, and judge what share of your actually-free money goes to AI. Part 3 of the series.
So my AI spending is 7.7 times the average. But whether that's too much depends on the ratio to income. Using rent benchmarks and the 50/30/20 rule, I work out what percentage of take-home pay AI can take, with a checker inside the post. Part 2 of the series.
I pay over 44,000 yen a month for ChatGPT, Claude, Cursor and the rest. How much does everyone else pay? Comparing survey data and user reports to work out whether I'm overdoing it. Part 1 of the series.
ChatGPT, Claude, Gemini. Before agonising over which one to pay for, ask whether the free tier's limits are eating your time. A simple rule for deciding when to start paying for AI.
Centred on the Claude Fable 5.1 release, plus Codex and OpenAI's new model Astra: I had an AI collect the AI news going around today and turned it into a post as-is. How usable is that, honestly?
Why I've kept using Notta since May 2023. Transcribing video I've already shot, then turning the AI summary into blog posts and teaching material: how I actually use it.
Long instructions to an AI are faster spoken. The honest story of buying Superwhisper's roughly 250-dollar lifetime licence on a "fine, just buy it" impulse, plus the free options — Speakly, Aqua Voice, and what your OS already has — in the order worth trying them.
We live in an age where you can ask an AI and end up with a working site without really understanding it. Is going on vibes fine? It turns out there are exactly five places worth being scared of, laid out for beginners.
Servers? Terminals? Without understanding any of it, I handed the job to an AI and my blog ended up on the internet. The five steps I actually took, the mechanics I understood afterwards, and one honest doubt: is this really OK?
Server? CDN? Starting from "what even is that", I published a blog with an AI and worked out what Cloudflare really is, explained for people who have never built a website. The hard words are quarantined in collapsible sections.
An introduction from Hanageruge, who actually gets his hands on AI tools and web services for fun. What this blog will do, what it won't write about, and why Cloudflare. It's the first post, so it runs long and loose.
