Shift-Ctrl-F: Semantic Search for the Browser transforms traditional webpage searches into a more user-friendly experience. It utilizes a deep learning model (MobileBERT fine-tuned on SQuAD) to process natural language queries, yielding more accurate and relevant search results compared to exact-string matching. This extension provides users with a powerful tool for exploring text-heavy content by simply typing their questions, thereby streamlining the research process on various webpages.
