The AI chatbot that I actually use?!

Snapchat's "My AI" is becoming properly useful for me simply because its quickly accessible on my phone's lockscreen.

You can place a shortcut to a specific person in Snapchat on your lockscreen, so now with one tap I can chat with a moderately helpful LLM that usually beats Siri for everyday questions (assuming it's not "hallucinating")

10/10 would recommend.
