A chatbot that answers from the real manual via semantic search — text + links + screenshots, with data never leaving the system (PDPA-safe)
Semantic manual search (embeddings + pgvector) — understands natural questions
Answers with text + links to the relevant screen + real manual screenshots
No external LLM — zero API cost, zero hallucination, zero data leakage
G-CHAT is the usage assistant embedded in the system — built so a new team can start using GCarbon without opening a thick manual.
Type "how do I add electricity for a new branch" and the system searches the manual with semantic search (multilingual embeddings + pgvector), answering with actual manual text, links to the relevant screen, and over 60 accompanying screenshots.
G-CHAT calls no external LLM — question embedding happens in the user's own browser, and no text is sent to any third party. That means PDPA safety, zero API cost per use, and no hallucinated answers: the system returns only text that genuinely exists in the manual.
The manual index is rebuilt on every release — answers always match the screens users actually see.
