Features

⚙️ Modular Architecture – Clean separation between search, scrape, and LLM workflows.
🤖 Multi-Model Support – OpenAI, Claude, Gemini, Mistral, OpenRouter, Ollama, or any OpenAI-compatible API (LM Studio, llama.cpp, Groq, etc.).
🔄 Live Model List – Models are discovered from each provider at startup, so new releases appear on their own and retired ones disappear. No hardcoded list to go stale.
🎚️ Tunable Depth – Sidebar controls for how many results to filter, how many pages to scrape, and how much of each page the model reads, with the token cost shown before you run.
🌐 Web UI – Streamlit-based interface for interactive investigations.
💬 Conversational Follow-ups – Ask grounded follow-up questions about an investigation without re-running the search — answered from that investigation's own data.
🔀 One-Click Pivots – Suggested follow-up queries surfaced from the findings; click one to launch a fresh investigation.
🐳 Docker-Ready – Recommended Docker deployment for clean, isolated usage.
🔍 Honest Results – When nothing relevant is found, Robin says so instead of summarizing whatever it happened to scrape.
📝 Custom Reporting – Save investigation output to file for reporting or further analysis.
🧩 Extensible – Easy to plug in new search engines, models, or output formats.

⚠️ Disclaimer

This tool is intended for educational and lawful investigative purposes only. Accessing or interacting with certain dark web content may be illegal depending on your jurisdiction. The author is not responsible for any misuse of this tool or the data gathered using it.

Use responsibly and at your own risk. Ensure you comply with all relevant laws and institutional policies before conducting OSINT investigations.

Additionally, Robin leverages third-party APIs (including LLMs). Be cautious when sending potentially sensitive queries, and review the terms of service for any API or model provider you use.

Installation

[!NOTE] The tool needs Tor to do the searches. You can install Tor using apt install tor on Linux/Windows(WSL) or brew install tor on Mac. Once installed, confirm if Tor is running in the background.

[!TIP] Provide your API key either in a .env file (copy .env.example) or as environment variables. One key is enough: Robin lists models for whichever providers it finds. Supported keys are OPENAI_API_KEY, ANTHROPIC_API_KEY, GOOGLE_API_KEY, MISTRAL_API_KEY and OPENROUTER_API_KEY.

For Ollama, nothing goes in your .env. Robin defaults to http://host.docker.internal:11434, which is what the recommended Docker install needs. Two things are still on you:

Run the container with --add-host=host.docker.internal:host-gateway (the README command already does).

Make Ollama listen on all interfaces, since it binds to 127.0.0.1 by default and a container cannot reach that. If you start it yourself, OLLAMA_HOST=0.0.0.0 ollama serve &. If it runs under systemd, , add and , then .

Docker [Recommended]

Pull the latest Robin docker image

docker pull apurvsg/robin:latest

Run the docker image as:

docker run --rm \
   -v "$(pwd)/.env:/app/.env" \
   --add-host=host.docker.internal:host-gateway \
   -p 8501:8501 \
   apurvsg/robin:latest

[!TIP] To persist saved investigations across Docker restarts, mount a local directory:
docker run --rm \
   -v "$(pwd)/.env:/app/.env" \
   -v "$(pwd)/investigations:/app/investigations" \
   --add-host=host.docker.internal:host-gateway \
   -p 8501:8501 \
   apurvsg/robin:latest
Investigations are saved to the investigations/ folder in your working directory and can be loaded from the Past Investigations panel in the sidebar.

Open your browser and navigate to http://localhost:8501

Using Python (Development Version)

With Python 3.10+ and Tor installed, run the following:

pip install -r requirements.txt
streamlit run ui.py

Open your browser and navigate to http://localhost:8501

Troubleshooting

Empty model dropdown, Ollama not showing up, Tor resolve failed errors, 401s, or "no results found"? See TROUBLESHOOTING.md before opening an issue.
