What it is

Jack The Butler is an open-source AI concierge for hospitality businesses, bringing WhatsApp, SMS, email, and web chat into one inbox. It can answer routine guest requests automatically and route more complex issues to staff with context. A property-specific knowledge base can inform guest responses. Jack supports Anthropic Claude, OpenAI GPT, Ollama, and built-in local AI models. It is self-hosted, and its documentation says guest data remains on the property's server. Local AI can work offline without API costs, though responses are simpler and models need about 2 GB of RAM. WhatsApp connects through the WhatsApp Business API, SMS through Twilio, and property email through SMTP/IMAP. Deployment options include one-click 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 fees or per-room pricing; hosting and AI API use may cost extra. The maker estimates production hosting at about $5–10 per month and AI API use at about $5–20 per month.
