Teams building custom AI chatbots across multiple surfaces (web, WhatsApp, Slack, API) with rich configuration.
Feature-by-feature
| Feature | IndexFox | Chatbase |
|---|---|---|
| Product shape | A search widget. One installable component per site. Search box first; AI answer is a generated response from retrieved passages. | A platform for building chatbots. Many channels — web, WhatsApp, Messenger, Slack, API. Designed to be configured into many shapes. |
| Retrieval quality | Hybrid vector + BM25 retrieval on ManticoreSearch, with cross-encoder reranking on top candidates. | Vector retrieval against your imported documents. Quality depends on chunking and your underlying model choice. |
| Where the user types | Cmd/Ctrl-K-style search box that scopes results to your site content. | Chat bubble — visitors converse with the bot. |
| Analytics | Search analytics: top queries, zero-result queries, typing vs committed, click-through. | Chat analytics: conversation volumes, lead capture, message-level feedback. |
| Customization model | Color, hotkey, branded host integration via postMessage. Iframe-isolated. | Persona, system prompt, instructions, conversation flows, multi-channel deployment. |
| Best fit | A focused search experience for a single site. | A chatbot deployed across many places and channels. |
When Chatbase is the right call
- You want a chatbot on more than just a website — Slack, WhatsApp, API.
- Persona / prompt configuration matters more than retrieval depth.
- You are building lead-capture conversation flows, not a search experience.
- You want a platform you can build many bots on, not one widget.
When IndexFox is the right call
- Your job is "add search to my website", not "deploy a chatbot everywhere".
- You want ranked results AND an AI answer, not only an AI answer.
- You ship technical content where exact-term recall (API names, SKUs) matters.
- You want a single, focused product instead of a platform with many knobs.
Chatbase is a chatbot platform. IndexFox is a search widget. If chatbots-everywhere is the job, Chatbase. If search-on-my-site-that-also-answers is the job, IndexFox.
