The Problem

The AI field moves at breakneck speed. Every day brings new ArXiv papers, trending GitHub repos, OpenAI announcements, and Anthropic updates. Keeping up is a full-time job.

The Solution: Pulse AI

I built Pulse AI - an autonomous agent that handles the entire news curation pipeline:

  1. Scraping - Pulls from ArXiv, GitHub Trending, RSS feeds, tech blogs
  2. Deduplication - Uses sentence embeddings to remove duplicates
  3. Summarization - Generates 3-sentence summaries + social hooks via Llama 3.3
  4. Publishing - Auto-posts to 6 platforms

The Tech Stack

  • LangGraph StateGraph for typed agent workflows
  • FastAPI backend with SQLite
  • Next.js 14 dashboard with Tailwind
  • Edge TTS for free podcast generation
