AI Assistants. What They Are, How They Work & Best Options

An AI assistant is software that uses artificial intelligence to understand, learn, and perform tasks that would normally require a human. From answering your phone to writing emails, scheduling appointments, and analyzing data, AI assistants are transforming how businesses operate.

Best AI Assistants for Business

Here are the top AI assistants businesses are using right now:

ChatGPT (OpenAI)
