Pangram is subjectively very useful and I personally subscribe, but the burden of proof is on them. The product is very much "trust me bro" and I fear that if they ever try to improve recall both their precision and reputation will tank.
Talking to the person who gave it to you, in my experience.
In my own testing, Pangram is excellent at detecting the default output styles of LLMs.
If you tell the LLM to change its output style, so it’s not full of “load-bearing spaced em dashes that aren’t X, they aren’t Y. they’re Z.” constructions (which humans are pretty good at detecting on their own), the false negative rate soars.
