Please, name a few good tools that can be used on mobile phones to enhance productivity, learning, Natural Language Processing, and conversations.
I would like an AI tool on my phone that automatically blocks spam calls from call-centers that try to sell you stuff or from Windows technical support.
I would not use ai for that. If spam was a problem for me, I would just have all calls go directly to voice mail. If you recognize the number then answer the call. I doubt most spammers, whether bot or real people, are prepared to leave a voice mail.
