About
Hello, I’m Daisuke
I write from a small flat in Sapporo, at a low table with a laptop, a mug of tea and a lot of snow outside. By day I do ordinary office work: emails, meeting notes, spreadsheets, the odd report. When AI tools began to turn up everywhere, I wanted to know what they were actually good for on days like mine.
So I started the letter. Each week I pick one kind of tool, such as a writing assistant, a meeting note taker or a chat assistant, and use it on real work for seven days. Then I write down what it did well, what it got wrong and what it cost. I do not name products and I do not take money from tool makers. I would rather you could use the notes with any tool.
What I sell are the things I use to keep the trials fair: a prompt notebook, a comparison sheet, checklists and prompt packs, and two short video courses. They are plain and they do not need any one tool.
Questions
How do the downloads arrive?
After checkout you receive an email with a download link, and the same link is shown on the confirmation page. Every file is a PDF made to read on a screen or print on ordinary A4 or Letter paper.
How do the video courses work?
You pay once and the lessons appear in your account straight away. Watch them in order or jump around, as often as you like, on a phone, a tablet or a laptop.
Is there merch?
Yes: tees, totes, mugs, prints and stickers with my own designs. Each is printed to order and shipped to you, and the cost and delivery time show at checkout.
Do you tell me which tool to buy?
No. I write about kinds of tools and what a week of use showed me, without naming products. The sheets and checklists work with any tool, so you can run the same fair trial yourself.
