Keeping people informed.

Community Notes (fka Birdwatch) lets people add helpful notes to tweets that may be misleading, and uses a technique called matrix factorization to determine which notes are helpful or not. The project takes into account the perspectives of raters who have rated notes similarly or differently in the past to rank the notes that are most widely helpful to create a better-informed world.

Integrating a fine-tuned generative pre-trained transformer with iOS's IdentityLookup framework to classify incoming SMS/MMS from unknown senders. Spam, phishing attempts, suspicious messages, known spammers, other languages, custom phrases, and other unwanted or dangerous text messages are filtered and silently delivered to the user's junk folder.
