spira-base: a knowledge base for arXiv papers

Hi Product Hunt community! 👋 I'm excited to share **Spira Base** — a self-hosted knowledge base built specifically for anyone who reads, collects, and manages arXiv papers. 🔍 The Problem Keeping up with research often leads to hundreds of saved PDFs and bookmarks that get lost in the noise. When you want to revisit a specific paper months later, exact-keyword searches fail if you don't remember the exact title or authors. 💡 The Solution Spira Base lets you build your own private research repository with powerful semantic retrieval: - Semantic Vector Search: Find papers by conceptual similarity rather than rigid keywords. Query what you're thinking, and find matches based on abstract context. - 100% Self-Hosted & Private: Deploy locally in your own environment. Your queries, notes, and research history never leave your infrastructure. - Stockpile & Organize: Maintain a clean, structured database of papers tailored to your workflow. Check it out here: https://asamiile.gumroad.com/l/s... I’d love to hear your thoughts, feedback, and feature suggestions from researchers, developers, and knowledge-management enthusiasts!
