Locus is an AI copilot for students, analysts, and anyone who works with large amounts of information in the browser. It rethinks the usual Ctrl+F workflow by turning it into natural-language search across web pages and PDF documents.
Natural-language search
Instead of guessing exact keywords, you can ask questions in plain English. Locus uses context to surface the most relevant passages, which is useful when you’re reading long reports, research papers, textbooks, or analytical documents.
Web + PDF workflow
Locus works as a browser extension and supports searching across both web pages and uploaded PDFs. It also helps you keep track of what you’ve found.
- Search across web pages and PDFs
- Search history
- Save results to favorites
- Daily index updates
AI summarization and plans
Locus can automatically summarize documents to help you capture the key points faster. The free plan includes core features with daily limits, while the professional plan removes limits on searches, documents, and actions, and adds access to newer AI models and OpenAI integration.
