+# 📡 ReputationRadar
+> Real-time brand intelligence with human-readable insights.
+
+ReputationRadar is a Streamlit dashboard that unifies Reddit, Twitter/X, and Trustpilot chatter, classifies sentiment with OpenAI (or VADER fallback), and delivers exportable executive summaries. It ships with modular services, caching, retry-aware scrapers, demo data, and pytest coverage—ready for production hardening or internal deployment.

+## Demo
+
+The video demo of the app can be found at:-
+https://drive.google.com/file/d/1XZ09NOht1H5LCJEbOrAldny2L5SV1DeT/view?usp=sharing
+
+
+## Feature Highlights
+- **Adaptive Ingestion** – Toggle Reddit, Twitter/X, and Trustpilot independently; backoff, caching, and polite scraping keep providers happy.
+- **Smart Sentiment** – Batch OpenAI classification with rationale-aware prompts and auto-fallback to VADER when credentials are missing.
+- **Actionable Summaries** – Executive brief card (highlights, risks, tone, actions) plus refreshed PDF layout that respects margins and typography.
+- **Interactive Insights** – Plotly visuals, per-source filtering, and a lean “Representative Mentions” link list to avoid content overload.
+- **Export Suite** – CSV, Excel (auto-sized columns), and polished PDF snapshots for stakeholder handoffs.
+- **Robust Foundation** – Structured logging, reusable UI components, pytest suites, Dockerfile, and Makefile for frictionless iteration.

+```
+Each service returns a normalised payload to keep the downstream sentiment pipeline deterministic. Deduplication is handled centrally via fuzzy matching, and timestamps are coerced to UTC before analysis.
+
+---
+
+## Quick Start
+1. **Clone & enter the project directory (`community-contributions/Reputation_Radar`).**
+2. **Install dependencies and launch Streamlit:**
+   ```bash
+   pip install -r requirements.txt && streamlit run app.py
+   ```
+   (Use a virtual environment if preferred.)
+3. **Populate the sidebar:** add your brand name, optional filters, toggled sources, and API credentials (stored only in session state).
+4. **Click “Run Analysis 🚀”** – follow the status indicators as sources load, sentiment processes, and summaries render.
+
+### Optional Docker Run
+```bash
+docker build -t reputation-radar .
+docker run --rm -p 8501:8501 -e OPENAI_API_KEY=your_key reputation-radar
+```
+
+---
+
+## Configuration & Credentials
+The app reads from `.env`, Streamlit secrets, or direct sidebar input. Expected variables:
+
+| Variable | Purpose |
+| --- | --- |
+| `OPENAI_API_KEY` | Enables OpenAI sentiment + executive summary (falls back to VADER if absent). |
+| `REDDIT_CLIENT_ID` | PRAW client ID for Reddit API access. |
+| `REDDIT_CLIENT_SECRET` | PRAW client secret. |
+| `REDDIT_USER_AGENT` | Descriptive user agent (e.g., `ReputationRadar/1.0 by you`). |
+| `TWITTER_BEARER_TOKEN` | Twitter/X v2 recent search bearer token. |
+
+Credential validation mirrors the guidance from `week1/day1.ipynb`—mistyped OpenAI keys surface helpful warnings before analysis begins.
+
+---
+
+## Running Tests
+```bash
+pytest
+```
+Tests cover sentiment fallback behaviour and core sanitisation/deduplication helpers. Extend them as you add new data transforms or UI logic.
+
+---
+
+## Working Without API Keys
+- Reddit/Twitter/Trustpilot can be toggled independently; missing credentials raise gentle warnings rather than hard failures.
+- Curated fixtures in `samples/` automatically load for any disabled source, keeping charts, exports, and PDF output functional in demo mode.
+- The LLM layer drops to VADER sentiment scoring and skips the executive summary when `OPENAI_API_KEY` is absent.
+
+---
+
+## Exports & Deliverables
+- **CSV** – Clean, UTF-8 dataset for quick spreadsheet edits.
+- **Excel** – Auto-sized columns, formatted timestamps, instantaneous import into stakeholder workbooks.
+- **PDF** – Professionally typeset executive summary with bullet lists, consistent margins, and wrapped excerpts (thanks to ReportLab’s Platypus engine).
+
+All exports are regenerated on demand and never persisted server-side.
+
+---
+
+## Troubleshooting
+- **OpenAI key missing/invalid** – Watch the sidebar notices; the app falls back gracefully but no executive summary will be produced.
+- **Twitter 401/403** – Confirm your bearer token scope and that the project has search access enabled.
+- **Rate limiting (429)** – Built-in sleeps help, but repeated requests may require manual pauses. Try narrowing filters or reducing per-source limits.
+- **Trustpilot blocks** – Respect robots.txt. If scraping is denied, switch to the official API or provide compliant CSV imports.
+- **PDF text clipping** – Resolved by the new layout; if you customise templates ensure col widths/table styles remain inside page margins.
+
+---
+
+## Legal & Compliance
+ReputationRadar surfaces public discourse for legitimate monitoring purposes. Always comply with each platform’s Terms of Service, local regulations, and privacy expectations. Avoid storing third-party data longer than necessary, and never commit API keys to version control—the app only keeps them in Streamlit session state.
