The takeaway
SiteGPT is a focused, easy way to turn a website into a chatbot. CertifChat is built for teams whose knowledge spans more than web pages: it crawls your site and sitemap and learns from PDFs, text files and Q&A, then grounds answers with hybrid retrieval (semantic vector search plus Postgres full-text search, merged with reciprocal-rank fusion) narrowed to the top-ranked chunks. Each answer gets a confidence score, and your dashboard shows the pages it used. Check SiteGPT's current capabilities on their site, as products change.
