Pact is a Chrome browser extension that integrates an AI assistant into the browser’s side panel. It combines two components: Claude, an AI model for conversation and reasoning, and Fo, a service that can carry out supported real-world tasks. The extension is designed to help users move from reading or browsing to taking concrete actions, such as sending an email, updating a document, or making a phone call, by first discussing ideas with Claude and then delegating the execution to Fo. The primary function of Pact is to provide an AI companion that reads the context of the current web page and engages in natural conversation. Users can ask questions, work through plans, or clarify thoughts without needing a perfectly structured prompt. Once a direction is clear, the user can ask Fo to perform a task using tools that have been previously authorized. Fo acts as a bridge to external services, including Google Workspace, phone and email tasks, and any custom MCP (Model Context Protocol) servers the user connects. The extension shows a proposed task before the user approves it, and it returns the status from Fo so the user can verify the outcome. Typical use cases include turning an article into an actionable idea, converting a location into a plan, or moving from a conversation to a first step toward completing a project. The workflow begins by opening a supported web page, clicking the Pact icon in Chrome, and starting a conversation. The user can then connect their Fo account through the extension’s settings, authorize the services they want to use, and begin asking for tasks. The extension does not sign in or connect accounts on behalf of the user; all service connections must be established within Fo separately. Technical requirements include downloading the extension as a ZIP file, extracting it to a permanent folder, and loading it as an unpacked extension in Chrome’s developer mode. The folder must contain a manifest.json file. After installation, the user pins Pact via Chrome’s Extensions menu and clicks the icon to start. The extension relies on the user having a Fo account and the necessary permissions and service limits for the tasks they intend to perform. The website provides examples of services available through Fo but notes that actual tasks depend on the user’s specific connections and permissions.
