Factual, trustworthy answers sourced 100% from your website
Never worry about an AI assistant inventing fake discounts or wrong policies. SiteMind uses strict Reciprocal Rank Fusion (RRF) hybrid retrieval and refuses to guess when information is not in your knowledge base.
Grounding Accuracy
Strict similarity floor prevents ungrounded hallucinations
Hybrid Retrieval
Fuses semantic embeddings with Postgres full-text & trigrams
Cosine Similarity Floor
Irrelevant passages rejected before prompting the model
Citation Transparency
Every factual claim links back to the exact source webpage or doc
Engineered for absolute accuracy and zero friction
Everything built into SiteMind is designed to solve real customer support challenges without operational complexity.
Reciprocal Rank Fusion (RRF) Hybrid Search
Pure vector search fails on exact SKUs, error codes, and phone numbers. SiteMind fuses semantic vectors with lexical full-text matching to find exact answers every time.
Honest Fallbacks & Safe Refusals
If a visitor asks a question that is not in your knowledge base, SiteMind politely states that the information is unavailable and offers a support contact link instead of making up a lie.
Prompt Injection Defense
Retrieved website passages and user inputs are strictly delimited as untrusted data, preventing adversarial visitors from jailbreaking or altering system behavior.
Transparent Clickable Source Citations
Every answer includes clean citation pills so your visitors can click directly through to read the original page or document.
How it works in 3 simple steps
Hybrid semantic & lexical search
The visitor query is searched across pgvector embeddings, full-text tsvector, and trigrams.
Similarity filtering & re-ranking
Top candidate passages below the similarity threshold are pruned to eliminate irrelevant noise.
Grounded generation with citations
Gemini generates a crisp answer citing the exact source passages with zero outside speculation.
Why fast-moving teams choose SiteMind
Hallucination Defense
Hard similarity gating and hybrid search ensure answers are 100% verified against your real content.
Standard LLM bots guess or invent convincing falsehoods when documents lack the answer.
Exact SKU / Keyword Search
Postgres tsvector and trigram matching find exact technical error codes, product model numbers, and part IDs.
Pure vector embeddings struggle to match specific numbers, serial codes, and acronyms.
Prompt Injection Defense
Delimited system prompts and sanitized context prevent users from hijacking the chatbot.
Vulnerable to "ignore all previous instructions" jailbreaks.
