@max_dutkin Nice work on this launch—the value proposition comes through right away. Congrats! 🚀
Finally something that lives up to the offline-first pitch - the timezone converter actually works without internet. Love the cmd-K palette for jumping between tools, makes it feel almost like a launcher.
the keyboard shortcut to jump between tools is honestly the first thing i tested and it just feels right, super snappy. love that everything actually runs in the browser too
love how everything runs client-side and the cmd+k palette actually feels instant, you nailed the keyboard-first flow
