The 2026 Summer Sale. 30% off everything until July 30.

My summer sale is live 🎉

From today until July 30, you get 30% off everything in my store with the discount code SummerSale2026.

Every product. The whole catalog. No exceptions.

Why now?

I don't know about you, but summer is the only time of year when my calendar actually breathes. Fewer meetings. Fewer deadlines. Slower days.

That makes it the PERFECT moment to do the thing you've been postponing all year: set up your knowledge system.

Think about it. Every year follows the same pattern. January: big plans. March: information overload is back. June: you promise yourself you'll get organized "when things calm down". Well, things just calmed down. In September, the wheels will start spinning faster and faster again, and you'll be too busy to build anything.

The people who feel on top of things in October are the ones who used the quiet weeks of summer to put a system in place. This sale is your nudge to be one of them.

What's in the store

Everything is 30% off. Here's the tour.

🚀 Obsidian Starter Kit
