What n8n chatbot templates would save you the most time?

We've been building a library of ready-made n8n recipes for chatbots, and we're giving them away free. There are 16 so far, and we'd like to know whether we're building the right ones.
What's in there at the moment:

• Lead capture: into HubSpot, Mailchimp, ActiveCampaign, Pipedrive, Airtable or Google Sheets, with consent handled where it matters

• Bookings: Calendly and Cal.com

• Support and orders: Zendesk tickets, plus Shopify and WooCommerce order lookup

• AI: an FAQ bot with email handoff, and a bot that answers from a Supabase knowledge base

• No AI needed: button-menu bots for when a decision tree does the job better and cheaper

They're all at n8nchatui.com/recipes.
What I'd really like to know:

1. What do you end up building over and over for clients?

2. Which tools are we missing? (Notion, Slack, Intercom, Stripe?)

3. Do you prefer AI-driven bots, or simple button flows?

If you've got a workflow you'd happily share, tell us about it. We'll credit anyone whose idea we build on.
