About
Locus AI is a browser extension designed to modernize the traditional Ctrl+F function by replacing exact keyword matching with natural language processing. The tool allows users to find specific sections within long-form content, such as research papers, legal documents, and detailed articles, by asking questions or describing the information they are looking for. Instead of requiring users to remember specific phrasing, the extension understands the context of a query and navigates directly to the most relevant portions of the active webpage or PDF document. Beyond simple search, the platform integrates several artificial intelligence features to assist with deep research and information synthesis. Users can generate summaries of entire pages or specific sections to capture key points quickly. The extension also includes tools for brainstorming related research topics and automatically generating study note cards to help with information retention. It operates through a sidepanel interface, providing a consolidated view of search history, favorite sections, and AI-driven insights without obstructing the main reading area. This tool is particularly suited for academic researchers, students, and legal or corporate professionals who frequently navigate dense, text-heavy documents. By automating the extraction of relevant details and providing high-level summaries, it reduces the cognitive load associated with manual scanning. The professional tier allows users to select specific AI roles and switch between various Large Language Models (LLMs) to tailor the response style to their specific needs, whether for casual browsing or technical analysis. Locus AI distinguishes itself by offering a "bring your own key" model for OpenAI integration, allowing professional users to use their own API keys for unlimited tokens. It supports a wide range of state-of-the-art models, including GPT-4o, Claude 3 Haiku, and Gemini 1.5 Flash. From a privacy perspective, the tool does not train its models on user data and implements an expiration policy where document data is automatically deleted after a set period, depending on the user's plan tier.

FAQs
How do I access the sidepanel for summaries and favorites?
The sidepanel view can be accessed by clicking the icon within the Locus search popup or by using the 'Show Sidepanel' option in the Chrome browser menu. This feature becomes available once you have validated your email address on your Locus account.
How does the OpenAI and ChatGPT integration work?
Professional users can integrate their own OpenAI API key to access unlimited tokens for models like GPT-4o. The key remains stored locally in your browser, and you can manage your own usage limits through your OpenAI account dashboard.
What measures are taken to protect my data privacy?
Locus does not store personal information or train AI models using your data; it uses Memberstack for secure account management. Document data is automatically deleted after a specific period based on your plan, though items marked as favorites are retained.
What should I do if a red dot appears on the extension icon?
A red dot indicates that a new version of the extension is available for update. While Chrome usually updates automatically, you can manually update by right-clicking the icon, selecting 'Manage extension,' and clicking the 'New Version Available' option.
Which AI models are currently supported by the extension?
The extension currently supports OpenAI GPT-4o, 4o mini, and 3.5, as well as Anthropic Claude 3 Haiku and Google Gemini 1.5 Flash. The developers typically update the available models within a few days of a new industry release.
