+# Biotech Agentic Analyst
+
+An agentic workflow for analyzing scientific papers: extract figures from PDFs using Datalab, then run CrewAI agentic flow to generate structured intelligence — key findings, biological significance, quantitative highlights, and knowledge-base tags — for each figure.
+
+We use:
+
+- [CrewAI](https://docs.crewai.com/) for multi-agent orchestration (Flow + Crew)
+- [Datalab](https://documentation.datalab.to/) for PDF conversion and figure extraction
+- [OpenRouter](https://openrouter.ai/) as the LLM provider
+- [Streamlit](https://streamlit.io/) for an interactive UI
+
+## How It Works
+
+1. Upload a scientific PDF
+2. Datalab runs a convert → extract process to identify and extract all figures, axis labels, and captions
+3. A CrewAI Flow with Analyst agent produces structured intelligence for each figure:
+   - Chart type and key finding
+   - Variables and conditions compared
+   - Quantitative highlights
+   - Biological significance
+   - Knowledge-base tags
+4. Results are displayed in the Streamlit UI with figure thumbnails
+
+## Set Up
+
+### Create .env File
+
+Create a `.env` file in the root directory with the following content:
+
+```env
+OPENROUTER_API_KEY=<your_openrouter_api_key>
+DATALAB_API_KEY=<your_datalab_api_key>
+```
+
+### Install Dependencies
+
+```bash
+uv sync
+source .venv/bin/activate
+```
+
+On Windows (PowerShell):
+
+```powershell
+uv sync
+.venv\Scripts\activate
+```
+
+## Run the Streamlit App
+
+```bash
+streamlit run app.py
+```
+
+Open the URL shown in the terminal (e.g. `http://localhost:8501`). Upload a scientific PDF in the sidebar and click **Run Analysis** to trigger the full workflow.
