Zettelkasten Explained Simply: How to Get Started
Notes pile up but the system doesn't work: links get saved, summaries get written, and none of it turns out to be usable later. Here's Zettelkasten without a Luhmann biography or an app comparison: what the method actually is, what notes you need, how to link them properly, and the one step to start with today.

Frequently asked questions
Who writes this blog?
Alex Bezrukov — founder, building Cruxly and Planio 100% bootstrapped, with zero investors. I run the code, product, support, and marketing for both products alone.
What is Cruxly?
An AI notebook for video, PDF, and web pages with one chat across multiple sources at once (a NotebookLM alternative), plus a Second Brain and single-source video/PDF/web-page analysis without a notebook, same as before.
What is Planio?
A web app for service companies running on-site tradespeople — bookings, scheduling, staff roles, and team income tracking in one place instead of a notebook and scattered chats.
How many investors do Cruxly and Planio have?
None. Both products are 100% bootstrapped, funded out of pocket.
What's this blog about?
AI, software engineering, learning systems, and productivity — grounded in engineering practice, not motivational slogans.
