One thread, from a sentence to a shareable address
It is worth following the line end to end, because the length of it is the point. Most invitation tools make you carry the work across several places: a designer for the look, a form builder for the replies, a spreadsheet to reconcile them, a messaging app to send it all. The Jitabi assistant collapses that into a single conversation, and the conversation runs all the way to a published site.
You begin with a message. Jitabi returns a draft page with the sections a real invitation carries. You reply with corrections, and the same page updates. You publish, and it gets a live myjoyfullday.site link. You paste that link into WhatsApp, and every guest answer writes itself onto a tracked list. No export, no re-upload, no second tool holding a copy that quietly drifts out of date.
