This weekend I’ve been launching PARAZETTEL V5, and from tomorrow, it’s going to be closed to new purchases.
Here’s why I’m doing this, and a link to get in, if you’ve missed everything so far…
PARAZETTEL V5

We’ve been building the same product for almost three years now, since I started writing about the topic of PKM back in early 2023.
It’s become a treasure trove of knowledge, however it’s going to keep getting older as the months pass, the app updates and new changes to the field of note-taking come about.
If I don’t make a clean break now, I’m going to be four years deep into improving something that has four year-old videos in it, that have become somewhat irrelevant.
And as much as it’s worked for me and so many others, it’s better to let it go in terms of marketing and sales and just continue support for those who’ve been previous users.
Thus we’re cutting things off here, taking the opportunity of being back in the UK with less overhead, and an exciting new project on the horizon of book publishing (Minimal Note-Taking) to go ahead with after shutting up shop.
After the book though, I’m excited to explore how I can bring more personalised solutions to people in the space of knowledge management for personal and small business use (as I’m building a knowledge base for my new 2-person business ProseLab right now, see more about this whole topic in the section below).
If you’ve not gotten hold of the entirety of Premium PARAZETTEL yet, including the template and all other bonus courses, it’s your very last chance…
Content for the week…
Here’s the highlight for the week, as I’ve not really posted anything large or long in terms of articles or videos…
I've been doing something similar for a while myself.

Built a social media scheduling tool on top of the @zernio_ API, and am planning to create an interactive resource teaching people to build their own useful features and functions into the app.

Teaching you how to do the same for your own Obsidian vault (i.e. building custom plugins) is going to be one of the things I focus on in the upcoming months, because I can see huge potential in custom, extensible workspaces for personal and small-business use.
By staying on this list, you’ll learn more about how I can personally help you out with building AI into your personal knowledge management system, through plugins and functions in general

Just a short one today – the overwhelming priority has been that launch for a couple of weeks now. But there’s more coming soon!
Talk then,
