It's in the works. I privately tested it on Twitter users but it wasn't giving the results I expected (for example, classifying Trump as an INTP most likely.) It seems the general writing style on Twitter is different than Reddit which may explain it. In the worst case, I may need to build my own custom dataset scraping the Twitter profiles of known celebrities and their MBTI types from personality-database.com and train a separate model.

Of course, I may simply repurpose this same model for Twitter once the current excitement dies down (to minimize 502 errors since I'm on a cheap hosting plan.)
