For each question, the agent can dive deeper into the user's answers by asking follow-up questions.\n\nThis chatbot template isn't fully \"agentic\" which makes it a bit more complicated and scripted but ensures a more deterministic user journey; suitable when you need more guide-rails on the experience.\n\nSee example survey here: https://docs.google.com/spreadsheets/d/e/2PACX-1vQWcREg75CzbZd8loVI12s-DzSTj3NE_02cOCpAh7umj0urazzYCfzPpYvvh7jqICWZteDTALzBO46i/pubhtml?gid=0&single=true\n\n### How it works\n* A chat session is started with the user who needs to enter the bot command \"/next\" to start the survey.\n* Once started, the template pulls in questions from a google sheet to ask the user. Questions are asked in sequence from left to right.\n* When the user answers the question, a text classifier node is used to determine \nif a follow-up question could be asked.\n* If not, the survey proceeds to the next question. Otherwise, an AI Agent will generate a follow-up question based on the user's response.\n* All answers and AI conversations are recorded in the Google Sheet.\n* When all questions are answered, the template will stop the survey and give the user a chance to restart.\n\n### How to use\n* You'll need to setup a Telegram bot ([see docs](https://docs.n8n.io/integrations/builtin/credentials/telegram/))\n* Create a google sheet with an ID column. Populate the rest of the columns with your survey questions ([see sample](https://docs.google.com/spreadsheets/d/e/2PACX-1vQWcREg75CzbZd8loVI12s-DzSTj3NE_02cOCpAh7umj0urazzYCfzPpYvvh7jqICWZteDTALzBO46i/pubhtml?gid=0&single=true))\n* Ensure you have a Redis instance to capture state. Either self-host or sign-up to [Upstash](https://upstash.com?ref=jimleuk) for a free account.\n* Update the \"Set Variable\" node with your google sheet ID and survey title.\n* Share the bot with users to allow others to participate in your survey.\n\n### Can I use this for WhatsApp?\nYes you can!
