This was so good. Many thanks to @MolliePayments for having us - we’re just getting started 🇪🇺🏗️

Last Wednesday, our HQ was full of builders.

People spent the evening building, exchanging ideas, helping each other out, and shipping in good company.
The energy throughout the night was unmatched!

Thanks to everyone who joined Build Night.

[DAY42 @DAY42_]

Europe is stacked. Talent. Potential.
And yet, we’re letting opportunities slip.

The best people are leaving, and ideas are fading.

We’re kicking off a new era.

An era where Europe isn’t just "nice to visit", but the place to build.‍

@Iris_northdune Thanks Iris! Mainly that it’s focused on thoughts only and that you can have control over which thoughts you want it to focus on.

I just wanted a super simple UI. Without distractions.

After you wrote multiple thoughts you can select how deep you want AI to look.

[Robbin Jansen @robbinbuilds]

Introducing: Mindwrite.
Journal your thoughts on the go! 🧠

App 1 of 6 in my personal challenge: prototyping 6 Apps in 6 weeks!

For this one I used Lovable and Cursor. 95% is coded by AI. Built in less than 12 hours.
