Artificial intelligence (AI) software features can vary widely according to the application and the specific technology they use. Here are some general features and variations that you can expect.

Google Assistant

Google Assistant is a great tool for people who are looking for a convenient way to interact with their smart devices without necessarily having to use their hands. It can be particularly helpful for people with disabilities or limited mobility, as well as those who are busy and need to operate on tasks. It is free to use now.

Cortana

Cortana is a virtual assistant software for people who use Windows and Microsoft productivity tools, such as Outlook, OneNote, and Office 365. It was developed by Microsoft, primarily for the Windows operating system, and can be used on PCs, smart phones, and Xbox One. It offers a wide range of features, including voice-activated commands, reminders, and search capabilities. Cortana is free to use now.

Azure

Azure AI, which was developed by Microsoft, provides a whole series of services that help developers build intelligent applications quickly and easily. You can get a free account that provides over 25 services. If you want an upgrade then you will have to pay for their advanced features or go with their pay-as-you-go model.

IBM Watson

Some applications IBM Watson has been used in include healthcare, finance, and marketing among others. It has a pricing plan you can choose from. Plus plan starts at $140/month.
