Locus

Locus is an AI-powered browser extension that replaces the traditional Ctrl+F with natural-language search. Instead of hunting for exact keywords, you describe what you are looking for and Locus jumps to the relevant section inside web pages and PDFs, then helps you summarize, brainstorm, and build study notes with LLM assistance.

Natural-language smart search

Use everyday language to find the exact section you need on any web page or PDF, catching matches that exact keyword search cannot.

AI summarization

Summarize entire pages or selected portions to save time and get the key takeaway quickly.

Research and study helpers

Locus AI helpers brainstorm research topics, suggest further reading, and generate note cards to help you retain information.

Multiple LLM backends

Choose from current models including OpenAI GPT-4o-family options, Anthropic Claude, and Google Gemini, with new releases added within days.
