Which AI agent is best for my business?
The deciding question is who the agent works for. Muse works for one person. Grok Bot and ChatGPT are general-purpose tools, for any kind of work, with plans for teams. Will works for the whole company: it’s in the ERP, the bank, the store, the CRM and WhatsApp, and it keeps operations moving.
