Worldbuilding
Mention a character, a place or an event once. The dossier, the reference count, the timeline and the web of who-knows-who all build themselves out of that one mention.
Type @ and a name in your script, the way you would write it anyway. From then on that name is a real thing your project knows about: every place it appears is counted, and the scene it appeared in is recorded, so "which chapter did she first say that?" is a click rather than an afternoon.
Nothing is filed by hand and nothing is filed up front. The dossier exists because you wrote the name, not because you remembered to make one.

Three kinds are there when you start. They are not a fixed list: name your own, give it a shape and a colour, and that shape carries through everywhere the thing appears.
Connections are typed, directional and worth a note: mentor, owes a debt to, does not know yet. Zoom out for the constellation, zoom in and each orb opens into the thing itself. It is how you remember that the sister of the uncle running the secret organization is your protagonist's long-lost cousin.
Date a beat and it lands on a shared timeline you can drag to reschedule. Trace one character and watch their thread cross everyone else's. And if your world does not run on Gregorian months, build the calendar it does run on and the timeline uses that instead.
A three-line note and a twelve-page dossier are the same kind of thing here, so you are never choosing a format before you know how much you have to say. Every character, place or event can own as many documents as it needs, with references and sketches sitting in them.
They open in the editor you already write your script in, because they are the same kind of document. Nothing new to learn, and nothing to rewrite to bring your existing notes across.

This is one half of the loop. See how a page gets made, read who builds this, or check what each plan includes.
