Your scopes

Each scope is its own personalized newsletter — pick what you want to stay sharp on, and the system finds the sources and writes you a deep, regular brief.

👋 Welcome! A “scope” is one newsletter on a topic you care about. Create your first one — describe it in plain words (e.g. “AI tooling for engineers” or “home espresso”), and we'll find the sources and write you a regular brief.

What do you want to stay sharp on?

Describe it in your own words. The more specific, the better the sources.

Name a few sub-topics and the people or publications you already follow. Niche topics have fewer clean feeds, so widening a little helps us reach 16–20 sources. Not sure? Hit Improve my scope and we'll broaden it for you.

Style

Depth sets how technical it gets. Style sets the shape — sharp how-to-use-it angles, a plain what-changed digest, or a warmer for-the-joy-of-it read. We pick a fit automatically; change it anytime.
