Sibyl

AI-powered deep research agent. Ask any question — Sibyl searches the web across multiple sources, reads dozens of pages, cross-references findings, and generates an executive-quality research report with analysis, predictions, and citations.

Not just another search summarizer. Sibyl is a research analysis platform — it does structured comparisons, SWOT analysis, Google Trends tracking, event timelines, and financial data visualization. All from a single question.

Quick Start

MCP Server (for Claude Code / Cursor)

pip install sibyl-research
claude mcp add sibyl -e DEEPSEEK_API_KEY=sk-... -- sibyl-mcp

Then in Claude Code:

"Research the impact of AI on software engineering jobs over the next 5 years"

"Compare NVIDIA vs AMD vs Intel for AI workloads"

"SWOT analysis of Tesla in 2026"

CLI

pip install sibyl-research
export DEEPSEEK_API_KEY=sk-...   # or OPENAI_API_KEY, GEMINI_API_KEY, etc.

# Standard research
sibyl "Canadian housing market outlook 2026"

# Deep research with predictions + market data + PDF
sibyl "Will NVIDIA maintain AI chip dominance?" -d 3 --symbols NVDA,AMD,INTC --pdf

# Chinese output
sibyl "加拿大移民政策变化" -l zh --pdf -o reports/

How It Works

You ask a question
  │
  ├─ Step 1: Decompose into 3-5 focused sub-questions
  ├─ Step 2: Generate 15-20 diverse search queries
  ├─ Step 3: Search across 4 engines (DuckDuckGo, Google News, Reddit, Wikipedia)
  ├─ Step 4: Scrape 15-20 sources (realistic browser headers, retry, Google Cache fallback)
  ├─ Step 5: Filter sources by relevance (LLM-scored)
  ├─ Step 6: Analyze each sub-question independently
  ├─ Step 7: Identify knowledge gaps → auto-search for missing info
  ├─ Step 8: Cross-reference sources (sentiment, consensus, disagreements)
  ├─ Step 9: Section-by-section synthesis (Summary, Findings, Analysis, Predictions)
  ├─ Step 10: Review and refine draft
  └─ Output: PDF/Markdown report with Table of Contents, citations, charts

Multi-Provider Support

Sibyl works with any LLM. Auto-detects from environment variables:

Provider	Env var	Model
DeepSeek	DEEPSEEK_API_KEY	deepseek/deepseek-chat
OpenAI	OPENAI_API_KEY	gpt-4o-mini
Anthropic	ANTHROPIC_API_KEY	claude-sonnet-4-20250514
Gemini	GEMINI_API_KEY	gemini/gemini-2.5-flash
GLM (ZhipuAI)	ZHIPUAI_API_KEY	glm-4-flash

Or configure multiple providers with roles:

# sibyl.yaml
providers:
  - model: deepseek/deepseek-chat
    api_key: sk-xxx
    role: analysis

  - model: gemini/gemini-2.5-flash
    api_key: xxx
    role: fast

  - model: openai/glm-4-flash
    api_key: xxx
    api_base: https://open.bigmodel.cn/api/paas/v4
    role: chinese
