sorry if this has already been asked. Anyone know of an Intercom-like widget that uses OpenAI (or other similar-performance LLM) to answer user questions automatically based on your existing support documentation?

Check out these? https://www.gosameday.com/ https://truelark.com/ I also know the founder of this but they may be too early for clients - not sure: https://www.linkedin.com/company/newo-ai/

Use Chatling.ai to create a AI chat bot for your documents. There are several of these. Catherine's suggestions are good: AI bots for lead gen.

intercom itself does this with the Fin bot fyi
