How do you choose your AI assistant?

Choosing the best AI assistant involves taking a number of very specific criteria into account. One of these is ease of use. To avoid wasting time, look for a tool with an intuitive, ergonomic interface. To help you get the hang of it, limit the features to your needs. There's no point multiplying them if you don't need them. The more functions you have, the longer and more time-consuming it will be to familiarise yourself with them.

This brings us to the choice of functions. To ensure that you get valuable help with your work, select an AI assistant that is capable of responding to your needs. Start by defining the issues and expectations you want to meet with this new digital tool.

As you've seen, artificial intelligence can do (almost) anything. If you take the time to study the different solutions on offer, you can easily find the ideal assistant.

You also need to be rigorous when it comes to accuracy and reliability. Some PDAs perform better than others. There can be major differences in terms of content writing, transcriptions and information retrieval. In these areas, you need to be particularly demanding to ensure that you get really high-quality assistance functions.

Finally, don't neglect data security. You will be sharing sensitive information with your digital assistant. Make sure that the programme takes all the necessary measures to limit the risks.
