The word limit for ChatGPT and similar tools is a function of the (large) hardware resources they need. The bigger the text being analyzed, the bigger the computational footprint. So that’s a function of their technology and outside of our control.
We do not discuss future product plans, but I can say that we expect to support Apple Intelligence once it’s released as part of Mac OS. Support for ChatGPT and other standalone chatbots is likely to resemble our support for bibliography software, in that we are unlikely to tie ourselves to any particular tool.
