## Recommendation: Tavily For this LangChain-based Python RAG chatbot, I'd choose **Tavily** as the managed web-search/retrieval provider. **Repo fit:** Retrieval is centralized in `RAGRetriever` (`retrieval/rag_retriever.py`), which returns `(Document, score)` tuples and formats sources. The README roadmap explicitly wants a web fallback "in case none of the personal documents contain relevant info." Tavily's `TavilySearch` returns answer-ready content plus source URLs that map directly onto the existing source-formatting pattern — a clean `HybridRetriever` or low-confidence fallback inside `query()`. **Docs I actually consulted (official):** - Tavily — `docs.tavily.com/.../langchain` + `tavily.com/pricing` - Exa — `exa.ai/docs/reference/langchain` - Brave — `docs.langchain.com` Brave tool page + `api-dashboard.search.brave.com/documentation/pricing` **Verified findings:** | | Tavily | Exa | Brave | |---|---|---|---| | Package | `langchain-tavily` | `langchain-exa` | `langchain-community` (BraveSearch) | | Output | LLM-ready grounded content + URLs (Search/Extract/Crawl) | Clean highlights via `ExaSearchRetriever` | Raw search snippets/links | | Free tier | 1,000 credits/mo, **no
