The repeated minute is the cost
The same answer, typed again by a person, is what the week spends. An agent gives that answer from the words you already trust, in the language the customer wrote in. The person is left for the conversation that needs a decision.
You pay for the period, not for every question
The license is one price for the month, six months, or the year. A saved answer stays free. There is no fee each time someone asks. Six months is 5% off. One year is 10% off. It does not renew by itself.
The queue gets shorter
Evening questions do not wait until morning. The agent is already on the channel your customers use. When the saved words run out, a person takes over, and the tone stays yours.
