# BrowseAI Dev

> Research infrastructure for AI agents. Real-time web search with evidence-backed citations and confidence scores.

BrowseAI Dev gives AI agents structured, verifiable web research. Unlike chat-based search engines, it returns JSON with extracted claims, cited sources, confidence scores, and contradiction detection — designed for programmatic evaluation by agents.

## Available As
- MCP Server: `npx browseai-dev` (12 tools)
- REST API: `https://browseai.dev/api/browse/*`
- Python SDK: `pip install browseaidev`
- LangChain: `pip install langchain-browseaidev`
- CrewAI: `pip install crewai-browseaidev`
- LlamaIndex: `pip install llamaindex-browseaidev`

Previously known as `browse-ai` (npm) and `browseai` (PyPI) — renamed to `browseai-dev` and `browseaidev`. The old names still work and redirect to the new packages.

## Key Capabilities
- **Search**: Web search returning ranked results
- **Answer**: Full pipeline — search, fetch, extract claims, verify, cite, score confidence
- **Extract**: Structured claim extraction from any URL
- **Compare**: Side-by-side raw LLM vs evidence-backed answer
- **Research Sessions**: Persistent multi-query sessions with knowledge accumulation
- **Feedback**: Submit result feedback to improve future accuracy

## Verification Pipeline
1. Web search (Tavily API)
2. Page fetch and parse
3. Claim extraction (Gemini 2.5 Flash)
4. BM25 sentence-level verification
5. Cross-source consensus detection
6. Contradiction detection
7. Domain authority scoring (10,000+ domains, Bayesian dynamic blending)
8. 7-factor evidence-based confidence score

## Confidence Score
Not LLM self-assessed. Computed from: source count, domain diversity, claim grounding, citation depth, verification rate, domain authority, consensus score. Contradiction penalty applied.
