yeah exactly my thoughts.
everyone didn't mean literally everyone.

everyone might not be using ai.
but i see myself reaching for it for every small thing these days.
it's like every curiousity or lifestyle choice or optimization is something ai can help research.
i am not saying it's really powerful or great. but the lure is undeniable. because of how low friction it has become.

Whether it’s tech, philosophy, history, or just great...
Show HN: PeerSplit–A free, P2P Splitwise alternative (local-first PWA)
Hey HN!I'm Tanay, and I just launched PeerSplit, a peer-to-peer, privacy-first app for splitting group expenses.I built it because I was pretty fed up with existing apps that track your data, throw ads in your face, or make you pay for "premium" features. So, I figured, why not build something local-first that respects your privacy?What’s different about PeerSplit:- No signup needed – It’s 100%...

thanks for the feedback!
the writing screen doesn't have multiple text fields, it's just one area for writing that has the last line highlighted since you can't edit previous lines.
and yes, it is possibly a bit difficult to understand because it's too minimal, i'm working on improving the UX and writing a guide/landing page that explains things.

Re:Show HN: I built an open-source local-first app to track my workouts

thanks for trying!
the timer on the top left tells you the total elapsed time on the workout, including pauses. whereas the main timer only does a countdown/stopwatch for the current exercise.
and yes, you can leave exercise and workout names empty. i'll add some basic validation everywhere.
and yes, do let me know how it goes after you try it out!
