I built an iOS app that lets you point your phone at a paper invite or screenshot, review the parsed details, and drop the event straight into your calendar, so you can capture meetings in seconds instead of typing.

It saddens me that we're basically abandoning standards and protocols for such tasks.

I think it makes sense to just screenshot an email, or make a photo of it and have AI extract semantics from it.

But a simple ical file could do this far easier. Or an improved ical. If email clients recognize and handle them better. If calendar apps handle them smoother and cleaner esp on desktop and web. If browsers handle and forward them to calendar webapps. If chat apps like WhatsApp or signal handle them natively. If service providers like a delivery company or a ticketing agency attach them consistently Etcetc

Now we are in a mess that within closed ecosystems, such standards and protocols work seamless. Within outlook, or gsuite it works. But cross their walls, and it falls apart. I'm pretty sure that's intentional by these tech giants to create artificial moats and lock in customers.

Great app, congratulations on the idea! Too bad I can't install it on Android.
