About NatSecPulse

What is NatSecPulse?

NatSecPulse automatically aggregates and summarizes defense and national security TECHNOLOGY news from leading industry sources and major news outlets. We use AI to cluster related stories and generate concise summaries, focusing exclusively on defense capability, military modernization, acquisition programs, and defense-industry technology.

Focus: Defense tech, weapons systems, military platforms, acquisition, cyber/space/missile systems, C4ISR, and national security technology. Generic political or economic news is automatically filtered out unless it directly relates to defense modernization or technology.

How It Works

1. Ingestion: Every 30 minutes, we fetch articles from trusted defense news sources
2. Deduplication: Articles are deduplicated using content-based hashing
3. Clustering: Related articles are grouped using Jaccard similarity (no embeddings - fast and efficient)
4. AI Summarization: Llama 3.1 8B generates headlines, summaries, and tags for each cluster
5. Scoring: Stories are ranked by recency, cluster size, and source authority
6. Static Generation: The page is pre-rendered for instant loading
