I built AiOn—an AI-native global intelligence layer unifying 30+ sectors , every country and delivering real-time, market-aware insights in every language of the world . - Devpost: https://devpost.com/software/aion-n75vj3 - GitHub: https://github.com/shikhar0777/anion-rdy - Demo: https://hackathon-deploy-tau.vercel.app/ - Video: https://www.youtube.com/embed/Y46hZFxaEHE?enablejsapi=1&hl=en_US&rel=0&start=&version=3&wmode=transparent - Team: 2 GitHub contributor(s) — Shikharpandey07 (1 commits), Shikhar Pandey (1 commits) ## Devpost submission (written by the team) No Devpost description available. ## README (from the GitHub repository) # AiON — AI-Powered Global News Discovery Platform with advance algo and latency A real-time, multi-source news intelligence platform with AI-powered summaries, trending detection, story clustering, and deep analysis. ## Architecture ``` ┌─────────────────────────────────────────────────────────────┐ │ Next.js Frontend │ │ Country/Category filters │ Feed (Trending/Latest) │ Story │ │ SSE real-time updates │ Framer Motion animations │ └─────────────┬───────────────────────────────┬───────────────┘ │ REST API │ SSE Stream ┌─────────────▼───────────────────────────────▼───────────────┐ │ FastAPI Backend │ │ Provider Router │ AI Router │ Feed Service │ SSE Endpoint │ │ Circuit Breaker │ Cache (stale-while-revalidate) │ └───────┬─────────┬──────────┬────────────────────────────────┘ │ │ │ ┌────▼──┐ ┌───▼───┐ ┌───▼────┐ │NewsAPI│ │Guardian│ │ GDELT │ ← News Providers (failover chain) └───────┘ └───────┘ └────────┘ │ │ │ ┌───────▼─────────▼──────────▼────────────────────────────────┐ │ Background Worker │ │ Ingest Loop │ Clustering │ Trending Scores │ AI Enrichment │ └───────┬──────────┬──────────────────────────────────────────┘ │ │ ┌────▼──┐ ┌───▼─────┐ │Postgres│ │ Redis │ ← Storage + Cache + Pub/Sub └───────┘ └─────────┘ ``` ## Quick Start ### 1. Prerequisites - Docker & Docker Compose - Node.js 18+ (for frontend) - Python 3.11+ (for running API/worker locally, or use Docker) ### 2. Clone & Configure ```bash cp .env.example .env # Edit .env with your API keys (all are optional — GDELT works without any keys) ``` ### 3. Start Infrastructure ```bash # Start Postgres + Redis docker compose up postgres redis -d ``` ### 4. Start Backend API ```bash # Create virtual environment python3 -m venv .venv source .venv/bin/activate pip install -r requirements.txt # Start API server uvicorn apps.api.main:app --host 0.0.0.0 --port 8000 --reload ``` ### 5. Start Worker ```bash # In a new terminal source .venv/bin/activate python -m apps.worker.main ``` ### 6. Start Frontend ```bash cd apps/web npm install npm run dev # Open http://localhost:3000 ``` ### All-in-One Docker (API + Worker + Postgres + Redis) ```bash docker compose up --build # Then start frontend separately: cd apps/web && npm install && npm run dev ``` ## API Keys | Provider | Key | Required? | Free Tier | |----------|-----|-----------|-----------| | GDELT | None needed | Built-in | Unlimited | | NewsAPI | `NEWSAPI_KEY` | Optional | 100 req/day | | Guardian | `GUARDIAN_KEY` | Optional | 500 req/day | | OpenAI | `OPENAI_KEY` | Optional | Pay-as-you-go | | Anthropic | `ANTHROPIC_KEY` | Optional | Pay-as-you-go | | Perplexity | `PERPLEXITY_KEY` | Optional | Pay-as-you-go | | Hygen | `PHYGEN_KEY` | Optional | Pay-as-you-go | **The platform works with zero API keys** — GDELT provides free global news data, and AI features gracefully degrade to deterministic summaries. ## How Real-Time Works 1. **Worker** polls news providers every 2 minutes (configurable via `INGEST_INTERVAL_SECONDS`) 2. New articles are deduplicated by normalized title hash and stored in Postgres 3. Articles are clustered by title similarity (SequenceMatcher, threshold 0.75) 4. Trending scores are recomputed: `score = w1*log(1+sources) + w2*recency + w3*velocity` 5. Worker publishes update events to Redis pub/sub 6. **SSE endpoint** subscribes to Redis channels and pushes events to connected browsers 7. **Frontend** receives SSE events and refreshes the feed with smooth animations ``` Browser ←SSE← API ←pub/sub← Redis ←publish← Worker ↓ Postgres (articles, clusters) ``` ## How Failover Works ### News Provider Failover - **Headlines chain**: NewsAPI → Guardian → GDELT - **Trending chain**: GDELT → Guardian → NewsAPI - Each provider has a **circuit breaker** (Redis-backed): - 3 consecutive failures → circuit opens for 60s - After cooldown → half-open state (1 trial request) - Success resets the circuit ### AI Provider Failover - **Summarization**: OpenAI → Anthropic → deterministic fallback - **Deep Explain**: Perplexity Sonar → OpenAI → Anthropic → snippet fallback - Structured JSON output with retry on malformed response ### Cache Strategy - **Stale-while-revalidate**: Fresh cache (2min TTL) + stale cache (10min TTL) - On provider failure: serve stale data + show "Last updated Xs ago" - **Single-flight refresh**: Only one worker refreshes a given cache key at a time ## Configuration ### Polling Intervals (`.env`) ``` INGEST_INTERVAL_SECONDS=120 # How often to fetch news ENRICH_INTERVAL_SECONDS=30 # How often to run AI enrichment TRENDING_INTERVAL_SECONDS=60 # How often to recompute scores ``` ### Cache TTLs (`packages/shared/constants.py`) ```python CACHE_TTL_FEED = 120 # Feed results: 2 min CACHE_TTL_STORY = 300 # Story detail: 5 min CACHE_TTL_CLUSTER = 180 # Cluster data: 3 min CACHE_TTL_EXPLAIN = 600 # AI explanations: 10 min ``` ### Trending Weights (`packages/shared/constants.py`) ```python TRENDING_W_SOURCES = 3.0 # Weight for unique source count TRENDING_W_RECENCY = 2.0 # Weight for recency boost TRENDING_W_VELOCITY = 1.5 # Weight for velocity (articles/30min) ``` ## API Endpoints | Method | Path | Description | |--------|------|-------------| | GET | `/api/meta/countries` | List available countries | | GET | `/api/meta/categories` | List available categories | | GET | `/api/feed?country=US&category=technology&mode=trending` | Get feed items | | GET | `/api/story/{article_id}` | Get story intelligence | | GET | `/api/cluster/{cluster_id}` | Get cluster detail | | GET | `/api/explain?cluster_id=1` | Get AI deep explanation | | GET | `/api/stream?country=US&category=general&mode=trending` | SSE stream | | GET | `/health` | Health check | | GET | `/health/providers` | Provider status + circuit breakers | ## Project Structure ``` aion/ ├── apps/ │ ├── api/ # FastAPI backend │ │ ├── main.py # App entry point + lifespan │ │ ├── config.py # Settings from env │ │ ├── database.py # SQLAlchemy models + engine │ │ ├── redis_client.py # Cache, pub/sub, circuit breaker │ │ ├── providers/ # News data providers │ │ │ ├── base.py # Abstract provider interface │ │ │ ├── newsapi.py # NewsAPI implementation │ │ │ ├── guardian.py # Guardian API implementation │ │ │ ├── gdelt.py # GDELT implementation (free) │ │ │ └── router.py # Provider failover router │ │ ├── ai/ # AI layer │ │ │ └── router.py # AI model router + failover │ │ ├── services/ # Business logic │ │ │ ├── clustering.py # Dedup + clustering │ │ │ ├── trending.py # Trending score computation │ │ │ ├── feed.py # Feed assembly │ │ │ └── story.py # Story intelligence │ │ └── routes/ # API route handlers │ │ ├── meta.py # Countries + categories │ │ ├── feed.py # Feed endpoint │ │ ├── story.py # Story + explain endpoints │ │ ├── stream.py # SSE streaming │ │ └── health.py # Health checks │ ├── worker/ # Background worker │ │ ├── main.py # Worker entry + loops │ │ └── tasks/ │ │ ├── ingest.py # News ingestion task │ │ └── enrich.py # AI enrichment task │ └── web/ # Next.js frontend │ ├── app/ │ │ ├── layout.tsx │ │ ├── page.tsx # Main page (split-screen) │ │ └── globals.css # Glassmorphism + nebula theme │ ├── co [README truncated for size] ## Detected evidence (automated analysis) Indexed codebase: 91 recognized source files, 454 KB. -

Then say: ``` Start all services (docker, API, worker, frontend) and test that all 8 categories work and AI enrichment uses Claude for summaries, OpenAI for trending, and Perplexity for deep explain. ``` ## What was just completed: 1. ✅ AI router rewritten — Claude/OpenAI/Perplexity each have dedicated roles 2. ✅ NewsAPI politics category fixed (uses /everything endpoint) 3. ✅ Worker enrichment does dual AI calls (Claude + OpenAI) 4. ✅ Category validation added to feed route 5. ✅ Frontend shows AI provider badges (Claude=orange, OpenAI=green, Perplexity=blue) 6. ✅ All 41 tests passing 7. ✅ Frontend builds successfully 8. ✅ DB schema updated (metadata_json column added to clusters) 9. ✅ Old AI enrichment data cleared (443 clusters ready for re-enrichment) ## What still needs to be done: - Start all services and do a live test - Verify each category returns articles - Verify AI enrichment logs show "Claude" and "OpenAI" being used - Verify Deep Explain button uses Perplexity ``` ### CLAUDE.md ```markdown # Aion — AI-Powered Global News Discovery Platform ## Project State (saved 2026-02-15) This is a complete hackathon MVP with user auth, notifications, and preferences. ## Architecture ``` /Users/ashok/Desktop/hackathon/ ├── apps/ │ ├── api/ # FastAPI backend (port 8000) │ │ ├── ai/router.py # AI provider routing (Claude, OpenAI, Perplexity) │ │ ├── auth.py # JWT auth: hash_password, verify_password, create_token, decode_token, get_current_user dependency │ │ ├── config.py # Pydantic Settings from .env (includes jwt_secret, jwt_algorithm, jwt_expire_hours) │ │ ├── database.py # SQLAlchemy async models (Article, Cluster, ClusterMember, User, UserPreference, Notification) │ │ ├── redis_client.py # Cache, circuit breaker, Redis Streams (SSE) │ │ ├── main.py # FastAPI app entry + ETag middleware + all routers │ │ ├── middleware/ # ETag + Cache-Control middleware │ │ │ └── caching.py │ │ ├── providers/ # NewsAPI, Guardian, GDELT news providers │ │ │ ├── base.py, newsapi.py, guardian.py, gdelt.py, router.py │ │ ├── routes/ # feed.py, story.py, stream.py, meta.py, health.py, auth.py, preferences.py, notifications.py │ │ └── services/ # clustering.py, trending.py, feed.py, story.py, embeddings.py │ ├── web/ # Next.js 16 frontend (port 3000) │ │ ├── app/page.tsx # Main page with SSE, filters, AuthProvider wrapper, modals │ │ ├── app/globals.css # Pure B&W editorial design tokens │ │ ├── components/ # Header, CategoryChips (with country selector), FeedList, FeedCard, StoryPanel, ChatSection, AuthModal, PreferencesModal, NotificationBell │ │ ├── hooks/useSSE.ts # Server-sent events hook (auto-resume via Last-Event-ID) │ │ ├── hooks/useAuth.tsx # Auth context + provider (JWT in localStorage) │ │ ├── hooks/useNotifications.ts # Notification polling at user's interval │ │ ├── lib/api.ts # Backend API client (includes auth, preferences, notifications functions) │ │ ├── types/index.ts # TypeScript interfaces (includes User, AuthResponse, UserPreferences, NotificationItem) │ │ └── public/aion.png # Aion logo (cropped, no whitespace) │ └── worker/ # Background worker │ ├── main.py # 4 async loops: ingest, cluster, enrich, notify │ └── tasks/ # ingest.py, enrich.py, notify.py ├── packages/shared/ # schemas.py (includes auth/prefs/notification schemas), constants.py ├── tests/ # 41 tests (all passing) ├── docker-compose.yml # Postgres (port 5433), Redis ├── .env # API keys (real keys configured) └── requirements.txt # Python deps (Python 3.13 venv at .venv/) ``` ## Recent Changes (2026-02-15) ### 1.
