Relay

Relay is a Chrome extension that solves a common frustration for AI tool users: having to repeatedly explain project context to every new chat session. It works by automatically capturing the important details—decisions, tasks, and constraints—from your conversations with AI tools like ChatGPT, Claude, and Gemini. As you work, Relay builds and maintains a living project brief that stays current with your latest decisions.

The tool stands out through its seamless integration with both browser-based AI chats and coding agents via the Model Context Protocol (MCP). This means your Claude Code or Cursor IDE agent can access the same project brief as your browser sessions, creating true bidirectional context sharing. The automatic capture eliminates manual note-taking, while the one-click brief injection makes starting new conversations dramatically faster.

Relay is particularly valuable for developers and technical users who frequently switch between AI chat interfaces and coding assistants. It eliminates the cognitive overhead of remembering what was decided in previous sessions and ensures consistency across all your AI tools. The free tier allows for experimentation, while paid plans offer more projects and deeper integration capabilities for serious users.
