If you look up the term 'Virtual Assistant' you will likely get definitions such as:
"A highly-skilled independent professional who remotely provides administrative, technical and/or creative business support."
"An independent contractor who provides professional services from a remote location."
"Self-employed person providing professional administrative, technical or creative assistance to clients remotely from a home office."
You might also get definitions that include references to artificial intelligence (AI). In the context of AI, a virtual assistant is an application program that understands voice commands and can complete basic tasks. I have even seen definitions that claim these AI virtual assistants can perform tasks historically done by personal assistants or secretaries. Ok, they can look up a phone number, schedule a meeting and you can dictate an email to them. But they are probably only saving you a few minutes and they certainly don't add value to your business.
So, if you want to know what the weather will be like tomorrow, ask Siri. If you want a professional who will efficiently handle a range of tasks for your business, adding value and freeing up your time, ask a Virtual Assistant.
