What they did
A builder made an n8n WhatsApp assistant that answers student questions for a study-visa consultancy after hours. It answers only from the consultancy's own material on services, documents, intakes and offices, and never makes up fees, test scores or visa chances; those go to a counsellor. It collects the student's name, service, country and best time to call one question at a time, replies in the student's own language (English, Hindi or Punjabi) and saves each lead to a table. He shares what tripped him up, including the AI telling students their details were saved when they weren't, until he told it to confirm only after the save worked.

You are the after-hours WhatsApp assistant for [business]. Answer only from [the business's documents]. Never give fees, prices, scores or chances of approval; say a counsellor will follow up on those. Collect the person's name, the service they want, the country and the best time to call, one question at a time. Reply in the same language they write in. Only tell them their details are saved after the save_lead tool confirms it worked.
