Are my prompts and chats shared with third parties or used to train AI models?
No. Our AI chat runs entirely on our own servers. Your prompts and chats are never shared with third parties, sold, or used to train any AI models. All conversations remain private and under your control.
How does the AI chat work?
Our AI chat uses a two-step approach: RAG (vector search) to find relevant content, followed by GraphRAG (knowledge-graph query) to connect concepts and provide contextualized answers. This combination reduces hallucinations and delivers more accurate, logically connected responses.
Can I trust the AI's answers?
Every AI-generated response is grounded in the curated content of meRfi® Microbiome, and key claims are traceable back to the underlying studies and references. We always recommend verifying critical information with the primary literature.
Does the AI have access to the full internet or external sources?
No. The AI is trained to answer questions using only the content within meRfi® Microbiome. It does not browse the internet or pull in unverified external sources.
How often is the content updated?
meRfi® Microbiome is continuously curated and updated to reflect the latest research in gut microbiota, probiotics, prebiotics, and FMT. New studies, references, and keyword entries are added as the field evolves.
How many sources and keywords are included?
The platform contains over 600,000 pages of content, more than 44,000 keywords, and over 22,000 referenced studies.
Can I access the original scientific literature referenced in the platform?
Yes. Entries include links to the original studies (authors, titles, journals), allowing you to verify the information and explore the primary literature directly.
