Open Deep Research

An AI-powered research assistant that performs iterative, deep research on any topic by combining search engines, web scraping, and large language models. If you like this project, please consider starring it and giving me a follow on X.

Features

• Iterative Research: Performs deep research by iteratively generating search queries, processing results, and diving deeper based on findings
• Intelligent Query Generation: Uses LLMs to generate targeted search queries based on research goals and previous findings
• Depth & Breadth Control: Configurable parameters to control how wide (breadth) and deep (depth) the research goes
• Smart Follow-up: Generates follow-up questions to better understand research needs
• Comprehensive Reports: Produces detailed markdown reports with findings and sources
• Concurrent Processing: Handles multiple searches and result processing in parallel for efficiency

Requirements

• Node.js environment
• API keys for:
  • Firecrawl API (for web search and content extraction)
  • OpenAI API (for o3 mini model)

Setup

1. Clone the repository
2. Install dependencies:

npm install

3. Set up environment variables in a .env.local file:

FIRECRAWL_KEY="your_firecrawl_key"
OPENAI_KEY="your_openai_key"

Usage

Run the research assistant:

npm start

You'll be prompted to:

1. Enter your research query
2. Specify research breadth (recommended: 3-10, default: 6)
3. Specify research depth (recommended: 1-5, default: 3)
4. Answer follow-up questions to refine the research direction

The system will then:

1. Generate and execute search queries
2. Process and analyze search results
3. Recursively explore deeper based on findings
4. Generate a comprehensive markdown report

The final report will be saved as report.md in your working directory.

How It Works

1. Initial Setup

   • Takes user query and research parameters (breadth & depth)
   • Generates follow-up questions to understand research needs better

2. Deep Research Process

   • Generates multiple SERP queries based on research goals
   • Processes search results to extract key learnings
   • Generates follow-up research directions

3. Recursive Exploration

   • If depth > 0, takes new research directions and continues exploration
   • Each iteration builds on previous learnings
   • Maintains context of research goals and findings

4. Report Generation

   • Compiles all findings into a comprehensive markdown report
   • Includes all sources and references
   • Organizes information in a clear, readable format
