What're the top 5 free ai assistants

As of my last knowledge update in October 2021, several AI assistants were considered popular and offered free versions that users could utilize. Here are five notable AI assistants that were well-regarded:

**Google Assistant**: Available on most Android devices and iOS, Google Assistant can perform a wide range of tasks such as answering questions, setting reminders, playing music, and controlling smart home devices.

**Amazon Alexa**: While traditionally associated with Amazon Echo devices, Alexa is available as a free app on smartphones. It allows users to interact vocally or through text, managing tasks, controlling smart home devices, and providing news and weather updates.

**Apple Siri**: Integrated into Apple devices, Siri provides voice-activated assistance to perform tasks like sending messages, setting alarms, and answering questions. Siri is user-friendly and utilizes machine learning for improved responses.

**Microsoft Cortana**: While initially designed as a stand-alone virtual assistant, Cortana's functionality has shifted more toward productivity assistance within Microsoft 365 as of late 2021. It still offers task management and reminders in free versions, primarily for Microsoft users.

**ChatGPT by OpenAI**: This AI language model provides conversational abilities, allowing users to ask questions, seek information, or generate creative content. While access may vary based on platform use, there are free access points available.

Please note that the landscape of AI assistants is rapidly evolving, and you may want to check for any new developments or offerings beyond 2021 to ensure you have the most current information.
