FAQ
What makes a chatbot platform effective?
Strong intent handling, clean human handoff, useful analytics, and a manageable training workflow matter more than flashy demos.
Are chatbot tools only for support teams?
No. They are also used in sales, onboarding, and internal service workflows, but support automation is still the most common starting point.
How should I shortlist chatbot vendors?
Shortlist by your automation goals, channel mix, internal technical resources, and the importance of agent handoff quality.
