About
Locus is a browser extension designed to upgrade the standard "find" (Ctrl+F) functionality with semantic search capabilities. Unlike traditional keyword matching, it uses AI to understand the intent and context of a user's query. This allows researchers and students to locate specific information within dense web pages and long PDF documents by asking questions or describing the concept they are looking for, rather than memorizing exact phrasing. It acts as an intelligent overlay that highlights relevant sections immediately, significantly reducing the time spent scrolling through irrelevant text. The tool integrates directly into Chrome or Brave browsers, providing a seamless workflow for searching and analyzing information. Beyond basic search, it includes a side panel where users can access advanced AI features like page summarization, brainstorming for new research ideas, and the automatic generation of study cards. It leverages a variety of leading Large Language Models, including OpenAI's GPT-4o, Anthropic's Claude 3, and Google's Gemini 1.5. For users concerned with costs or privacy, the extension supports a "bring your own API key" model for OpenAI, ensuring tokens are handled directly via the user’s account. Locus is primarily built for academic researchers, legal professionals, and students who frequently interact with long-form content. It is particularly useful for those managing large volumes of PDFs or technical documentation where keyword search often fails to capture the nuances of a topic. By allowing users to "talk" to their documents, it reduces the cognitive load of skimming through hundreds of pages to find a specific data point or argument. The tool also includes a history and favorites system, allowing users to refer back to previously discovered matches and insights across different sessions. What sets Locus apart is its focus on privacy and flexibility. It does not store personal information or train models on user data, and document data is automatically expired based on the user's subscription plan. Its ability to switch between different AI models and specialized roles allows users to tailor the search experience to their specific field, such as legal analysis or scientific review. This hybrid approach of a browser utility and an AI research assistant makes it a lightweight but powerful alternative to more cumbersome document management platforms.

FAQs
How do I access the sidepanel for summaries and favorites?
The sidepanel is accessible through the Locus search popup icon or via the 'Show Sidepanel' option in Chrome. Users must have a validated email on their Locus account to use this feature.
How does the OpenAI integration work?
Locus requires users to provide their own OpenAI API key for unlimited use of models like GPT-4o. The key stays within your browser and is not sent to Locus servers, allowing you to set your own usage limits.
How is my data protected while using the extension?
Locus does not store personal information and uses Memberstack for account management. Document data expires and is deleted automatically after a period determined by your plan, and data is never used to train models.
What does a red dot on the extension icon signify?
A red dot indicates that a new version of the extension is available. While Chrome usually updates automatically, you can manually update by navigating to the extension's options page and selecting the new version.
