Summary

Jack The Butler is an open-source AI concierge for hotels and hospitality businesses. It combines WhatsApp, SMS, email, and web chat in one inbox, where it can answer routine guest requests and send more complex issues to staff with context. Its knowledge base can be trained on property information for guest responses. Jack supports Anthropic Claude, OpenAI GPT, Ollama, and built-in local AI models. It is self-hosted, and the product documentation says guest data stays on the property's server. Local AI can run offline without API costs, though its responses are simpler and models require about 2 GB of RAM. WhatsApp connects through the WhatsApp Business API, SMS through Twilio, and property email through SMTP/IMAP. Deployment options include cloud deployment and Docker installation. A REST API covers conversations, guests, tasks, knowledge-base entries, staff, and settings. The software is free and open source, with no per-message or per-room pricing; hosting and AI API usage may cost extra. The maker estimates production hosting at about $5–10 per month and AI API use at about $5–20 per month.

Jack The Butler suits hotels, vacation rentals, hostels, and property managers who want to handle guest messages across several channels. It is also relevant to operators who want to self-host guest data or use local AI.
