Locus
AI-powered browser extension for intelligent web page search and information synthesis.
About Locus
Locus AI is a browser extension that reimagines the Ctrl+F search function with artificial intelligence capabilities. It allows students and analysts to quickly find information on any web page using natural language queries rather than traditional keyword matching. The tool immediately locates relevant sections and content based on the user's intent, making research and information gathering significantly faster. A key limitation is that it appears to be limited to browser-based web page searches rather than offering broader information synthesis across multiple sources.
