Hey there, I’m Alexander.

I’m interested in how software can better serve people’s daily lives.

My experiments often involve designing and developing many ideas — some of which I build into publicly available products, which further informs my research. Below is a compendium of my research areas, projects, and products.

My work is graciously supported by the community — if you want to join us, see memberships.

    The future of the operating system

    In my current work, I am exploring new and renewed ideas for how personal computing can expand what people are able to think and do.

    This work is primarily shaped by exploring the “operating system of the future,” and creating an experi­mental new environment for personal computing.


    These projects experiment with the concepts from my research on the future of the OS in real-world use cases.

    Reimagining email

    My career began with reimagining email and finding ways to build that vision on top of the existing email protocols.

    Mail Pilot is an email client that introduced new perspectives and useful features to email in 2012, including reminders (later adopted by other apps as “snooze”). After a record-breaking Kickstarter campaign, it went on to become the #1 paid app in the Mac App Store at launch. It is available today as a native app for macOS and iOS.

    Throttle is a service that introduced sender-specific addresses in 2015 to give email receivers fine-grained oversight and control over the transactional and bulk email headed their way, and is often turned to as a home away from the inbox for less urgent email.


    These products have come from of my research and experimentation in email.

    My core work is independent research in software. I’m deeply curious about the future of personal computing. I believe it’s one of the most important things we’ve ever made, and that it’s in its infancy; that we’re still settling into the medium this new technology enables.

    Over time, I’ve found that the journey to quality is quantity, and as such, I try to engage in many small experiments throughout my work.

    You can see pretty much everything that I work on over here: Pretty Much Everything.

    Some other things: Songs I'm Made Of is a show I host in which songwriters tell their story in episodes woven together with both their own songs and the ones that inspire their work. In the first season, we met nine fantastic songwriters. Season two will begin soon. Simple Habits is a simple app for tracking habits from your phone. And you can check out everything else at Pretty Much Everything.
