AI Inbox Agent vs Chatbot
They solve different problems. Chatbots handle inbound website visitors. AI inbox agents like Underfive handle outbound email and DM replies. One is for support, the other is for sales.
A chatbot sits on your website waiting for visitors to ask questions. An AI inbox agent connects to your cold email tools and responds to people you've reached out to. Completely different use cases.

When should I use a chatbot?
Use a chatbot for inbound website traffic. Chatbots answer visitor questions, guide them through your site, and can hand off to support teams. They're great for customer support, FAQ automation, and qualifying inbound leads who find your website.
When should I use an AI inbox agent?
Use an AI inbox agent for outbound sales. When you send cold emails or LinkedIn messages and people reply, Underfive reads those replies and responds. It's designed to handle sales conversations, overcome objections, and book meetings.
Can a chatbot replace an AI inbox agent?
No. Chatbots don't connect to email. They sit on your website. An AI inbox agent connects to Smartlead, Instantly, HeyReach, and other outbound tools. They handle completely different channels and use cases.
Do I need both?
If you have both inbound website traffic AND outbound sales campaigns, you might need both. A chatbot handles website visitors. Underfive handles your cold email and DM replies. They complement each other.
Is Underfive a chatbot?
No. Underfive is an AI inbox agent, not a chatbot. It doesn't have a website widget. It connects to your outbound tools via webhooks and handles email and LinkedIn DM replies for sales teams.
