AI chatbot for websites
IndexFox vs SiteGPT: search-and-answers widget vs chat-only assistant
SiteGPT trains a chatbot on your website and answers in a chat bubble. IndexFox is a search widget first — ranked results, AI answers, analytics — chat is one surface, not the whole product.

IndexFox is best for
Teams who want a real search experience — ranked results, instant search, AI answers — not just a chat bubble.
SiteGPT is best for
Teams who want a friendly Q&A chatbot on their marketing site, with the chatbot as the primary (often only) surface.
Feature-by-feature
| Feature | IndexFox | SiteGPT |
|---|---|---|
| Primary surface | Search box with instant results + AI answer. Users see ranked, linkable passages, not only a paragraph of generated text. | Chat bubble in the corner. The interaction is conversational. Results are an AI-generated reply, with optional source links. |
| Retrieval | Hybrid (vector + BM25) at the engine level on ManticoreSearch, with reranking. Designed to recover product names, SKUs, and exact phrases. | Vector retrieval over chunked website content. Strong on semantic Q&A, weaker on exact-term and SKU lookup. |
| Crawler | Included. Crawls + reindexes with segment-level content hashing. | Included. Indexes URLs, sitemaps, and uploaded files. |
| AI answers | Streaming RAG with reranker on retrieved passages. Citations link back to the matched section anchor on your page. | Streaming chat replies grounded in your data, with optional citations. |
| Best fit | Marketing sites, docs, help centers, and e-commerce where users actively search. | Marketing sites where visitors prefer to ask questions in a chat UI rather than search. |
| Analytics | Search analytics with typing-vs-committed query split, top queries, zero-result tracking, click-through, ClickHouse-backed. | Conversation analytics — chats, lead capture, feedback ratings. |
| Installation | One script tag. Iframe-isolated widget. Cmd/Ctrl-K to open. | One script tag. Floating chat widget in the corner. |
When SiteGPT is the right call
- Your visitors expect a chat experience, not a search experience.
- You want to capture leads inside the chat conversation.
- You do not care about ranked, browsable results — only the final answer.
- Brand voice and appearance customization matter more than retrieval depth.
When IndexFox is the right call
- You want users to search and browse ranked results, not only chat.
- You ship a docs site or product where exact-term lookup matters (SKUs, API names).
- You want hybrid retrieval (vector + BM25) and rerank-quality result ordering.
- You want search analytics — what people typed, what they clicked, what returned zero results.
SiteGPT is excellent at chat. IndexFox is excellent at search with AI answers as a layer on top. They live next to each other in the budget — pick the one whose primary surface matches how your users want to find things.
