What does an AI virtual assistant do?
AI Virtual assistants can take over various tasks:
taking meeting notes and transcribe them
scheduling meetings for you
taking over single office tasks
The AI industry is working on AI Agents as the next big thing. These AI assistants can do various office tasks from beginning to end instead of requiring prompts within the workflow.
For this comparison, we focused on the AI Virtual assistants that are already available and are not voice-commanded (like Alexa or Siri). Two of our three contestants offer plans for free virtual assistant services.
Sometimes, chatbots are also referred to as virtual assistants because they handle customer inquiries. We have created a separate section for bots here, take a look!
Also, our review contains a few affiliate marketing links. If you purchase any of the tools, we might receive a small commission.

Spoiler Alert
When comparing Otter.ai and Fireflies.ai, I have found them to be quite similar. However, I personally prefer the interface and clarity of Fireflies.
But if you are looking for a better free deal, Otter.ai’s free plan is more generous.
I appreciate how easy it is to toggle both tools on and off for meetings.
IBM’s Watson and their lite plan was extremely hard to sign up to and generally it is setup for enterprises,so do not recommend this tool for small businesses.

Interview with Fireflies.ai ceo Krish Ramineni:
Do you have any tips, tricks or hacks regarding the use of AI?
Be as objective as possible when interacting with AI. AI picks up on your biases and can sometimes BS answers. It's very good at making things seem accurate. Over time this will get better, but we have to be mindful in the way we provide instructions.
