AI-powered search and summarization tool for PDFs and web documents

Locus is a productivity tool company focused on enhancing document and research workflows through AI-powered search and summarization capabilities. Founded in the early 2020s, the company has developed a browser extension that allows users to search PDFs and web pages using natural language queries, bypassing the limitations of traditional keyword-based search. Their product suite includes features like AI-generated summaries, note cards for retention, and favoriting systems for quick reference.

As of 2025, Locus reported $2M in annual recurring revenue, with customer success managers driving expansion revenue even during government shutdowns. The company operates on a freemium model, offering limited free access with paid tiers for unlimited document processing. Their user base spans financial analysts, academic researchers, and students, with notable traction in institutional settings like Goldman Sachs and University of Pennsylvania research labs. The product's differentiation lies in its contextual understanding of documents rather than simple keyword matching, though it faces competition from larger productivity suites adding similar AI features.
