Chat & assistantsIndependent and commission-free: vona is not affiliated with the vendors. The “Last checked” date shows when we last compared features, prices and data protection information with the vendor’s public information; the vendors’ information remains authoritative.
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.
