What to look for when choosing
Check whether the vendor offers a business plan with a data processing agreement and does not use inputs for training there. Find out how long a document the assistant can handle at once, whether it connects to your applications and which usage limits you will notice day to day. A personal account has no place in everyday work with sensitive customer data.
