Show HN: I built an LLM powered receptionist for website chats

https://receptionst.com/
6•teemingdev•1h ago
I built Receptionst after noticing a pattern across my own projects. Visitors would open the website chat widget, ask a question and leave before I could answer. If it happened during deep work I missed it. If it happened overnight I never saw it at all. It became obvious that I could not respond instantly which meant I was losing leads without realizing it.

I wanted something lightweight that acted like a receptionist by giving instant LLM powered answers based on my own content and by collecting lead details when visitors showed intent. I kept the scope narrow so setup is simple. You connect your site, add the info you want it to know and it starts responding with context from your docs, pricing pages and FAQs.

I am happy to answer questions about the tech choices, the prompting, or the things I would do differently.

Are users using all your features?
teemingdev•49m ago
Yes, because the features currently offered are quite minimal! My plan is to release new features in the upcoming week
