My idea is the following:
A mechanical typewriter that 'corrects' reality within 6 meters of it so that any statement typed on it is true. Containment would just be put it in a room bigger than the area of effect and don't let peopple in. There would also be a test log exploring the specifics of how it works.

Do you think this is worth developing?

A mechanical typewriter that 'corrects' reality within 20 feet of it so that any statement typed on it is true.

/me types "this typewriter is no longer anomalous".

Alternatively, "the area of effect of this object is 0 meters" (remember, scientists use metric), or "this object was never anomalous" or "this object cannot be used by any species besides ants" or "nothing typed on this object from now on will ever take place".

I feel like I've seen variants of this sort of "truth-maker" pop up every month. Not exactly the most interesting object by today's standards, but maaaaaaaybe doable if you put in enough time and effort into breaking through the overplayed trope with a unique twist.

I've corrected the measurement.
I've thought a bit about how the effect would work. The object wouldn't be able to affect itself, attempts to do so would result in changes to definitions. Paradoxes would be affected the same way.
Another bit is that typed statement would have always been true within the affected area, altering the whole timeline within the area of effect.

Does this make it any better?
