Locus
FreemiumBrowser extension that adds AI search and summaries to pages
What is Locus?
Locus is a browser extension that replaces keyword find with natural-language search on web pages and PDFs. It also summarizes pages and creates study cards, aimed at students, researchers and analysts reading long documents.
You describe what you are looking for and Locus jumps to the relevant section, which helps with long papers, articles and documents where you cannot recall the exact word. AI helpers can summarize a page or a selection, suggest follow-up topics and make note cards to help you remember key facts.
A Favorites feature saves highlighted answers so you can return to them across documents. The free plan covers three documents a day with smart search and AI helpers, and a Professional plan removes those limits.
