Sounds reasonably handy, do you rely on users to tell you if the LLM generated simplifications are misleading? It is clearly doing more than just popping up definitions of confusing words, kudos for that.

This makes me want a tool that lets the scientists (who obviously are fine writers but don't specialize in writing) write at whatever level of detail they want, and then shorten or lengthen it to different audiences. EXCEPT the actual authors would verify and publish specific alternates.

I think it's great to have a 3 page short paper for super experts in a short journal article (though I don't see why journal articles have page limits in 2023). I think it's better if that three page paper can be turned into a ten page paper that's way easier to read and which the authors actually vetted as accurately representing what they did.
