phi-thread — Answer Router

Stop searching the same question across 5 tabs. phi-thread searches Stack Overflow, Reddit, Hacker News, GitHub, and the web simultaneously — and deep-links to the EXACT answer, not just the question page. How it works: • Google sidebar — search anything on Google, phi-thread shows answers from other platforms right alongside • Platform panels — on a Stack Overflow question? See what Reddit and HN say. On Reddit? See the SO accepted answer • Popup search — click the icon, type any dev question, get ranked results instantly Thread math: every answer on every platform has a permanent coordinate. phi-thread links to stackoverflow.com/a/38716397 (the accepted answer), not /questions/38715934 (the question page). Features: • Searches SO, Reddit, HN, GitHub, and DuckDuckGo in parallel • Deep-links to accepted answers, top comments, exact HN comments • Self-building keyword index — gets smarter with every search • 24-hour cache — repeated queries are instant • Zero API keys needed
