What is human handoff? Definition for AI chat

Human handoff is when an AI agent passes a conversation to a person, with the transcript and key details, because the visitor asked or the AI reached a limit.

How it works

A handoff has three parts: a trigger, a transfer and a fallback.

Triggers. Microsoft's Copilot Studio documentation distinguishes implicit triggers, where the agent can't work out what the customer wants or the customer types something like "talk to agent", from explicit triggers, where the builder decides that certain topics always go to a person (Microsoft). Common triggers on websites:

• the visitor asks for a person;
• the question isn't covered by the agent's sources;
• the topic is sensitive: refunds, contracts, legal or medical questions, complaints;
• the conversation signals a valuable sales opportunity.

Transfer. The person picking up should not have to start over. Microsoft's docs describe sending the full conversation history along with context such as the last topic and the visitor's phrases, so the live agent "continues the conversation" instead of restarting it.

Fallback. If nobody is available, for example at night or on weekends, the agent should say so honestly and collect what's needed for a follow-up: name, email and the question.

Why it matters for your website

Handoff is what makes an AI agent safe to deploy. An agent that may not say "I don't know" will guess, and guesses produce hallucinations. An agent that hands off well can stay strictly grounded, because there is always a next step for the visitor.

It also matters for how AI tools are priced. Intercom, for example, bills its Fin agent per "outcome". Its pricing page says you pay nothing if the customer asks to speak to a human at any point, while its FAQ also counts a completed workflow, "including handoffs", as an outcome (Intercom). When comparing tools, ask each vendor exactly how handed-off conversations are counted.

Measure handoffs rather than minimizing them blindly. A rising handoff rate on one topic often points to a missing or unclear page, not a bad agent.

Example

A visitor writes: "We were charged twice this month. I need this fixed today."

1. The agent recognizes a billing dispute, which is set to always go to a person.
2. It replies: "I'm sorry about that. Billing corrections need our team. I'm passing this on now with your message."
3. If someone is online, they join the chat and see the transcript and the account email.
4. If not, the agent says when the team will reply, confirms the email address, and creates a ticket with the full conversation.
