What is Relay?

Relay is a cross-AI context management tool that captures decisions, tasks, and constraints from your AI chats and keeps a living project brief ready. It works across ChatGPT, Claude, Gemini, Grok, Perplexity, DeepSeek, and 20+ tools via MCP (Model Context Protocol). Users rely on Relay to stop repeating themselves to every AI and ensure every fresh conversation starts where the last one left off. It offers a Chrome extension and MCP for your IDE, and is free to start.

Application scenarios

Cross-AI project management
Capture decisions made in ChatGPT and automatically sync them to Cursor or Claude Code for consistent development.
IDE agent collaboration
Connect Claude Code, Cursor, Codex, Antigravity, Windsurf, or GitHub Copilot to share the same project brief as browser chats.
Context restoration
Open a new chat in any supported AI and inject the full project brief with one click, avoiding manual copy-pasting.
Constraint tracking
Set constraints (e.g., "No third-party auth providers") in one tool and have them appear in another session automatically.
Task delegation
Define tasks in ChatGPT (e.g., "Implement auth flow, add RLS policies") and have them visible to your coding agent in the IDE.
Multi-tool workflow
Work across browser chats and IDE agents simultaneously, with decisions flowing both ways without manual syncing.

Core Features

Auto-capture
Relay quietly saves decisions, tasks, and constraints from every AI chat in ChatGPT, Claude, or Gemini without manual saving.
Project briefs
The project brief updates itself as you work, and you can inject the full context into a new chat with one click.
MCP integration
Claude Code, Cursor, and any MCP-compatible agent connect directly to read and write project memory, sharing the same brief as browser chats.
Cross-surface sync
Decisions made in ChatGPT surface in Cursor, and constraints set in Claude Code stay in sync with your next browser session.
Two-way context flow
What you decide in the browser reaches your IDE agent via MCP, and vice versa, creating a calmer loop than copy-pasting transcripts.
Browser extension
Available as a Chrome extension for easy integration with supported AI chat tools.
IDE agent support
Works with Claude Code, Cursor, Codex, Antigravity, Windsurf, and GitHub Copilot via MCP.

Target users

Software developers and teams using multiple AI tools (ChatGPT, Claude, Gemini, Grok, Perplexity, DeepSeek) alongside IDE agents like Cursor, Claude Code, and GitHub Copilot. Project managers and product builders who need to maintain consistent context across different AI platforms without manual note-taking.

How to use Relay?

Start by installing the Chrome extension or setting up the MCP for your IDE. Work in any supported AI (ChatGPT, Claude, Gemini, etc.) and Relay automatically captures decisions, tasks, and constraints from the conversation. Open a fresh chat in any supported tool and inject your project brief with one click to continue where you left off. For IDE agents, connect via MCP so they can read and write to the same project brief as your browser chats.

Pricing and free trial

Relay is free to start, as stated on the website ("Free to start").

Effect review

Relay addresses a real pain point for anyone juggling multiple AI tools: context fragmentation. The automatic capture of decisions, tasks, and constraints eliminates the need for manual note-taking or transcript copying. The cross-surface sync between browser chats and IDE agents is particularly valuable for developers who switch between ChatGPT and coding tools like Cursor or Claude Code. While the tool is free to start, its effectiveness depends on how well the auto-capture extracts meaningful context from varied conversations. For teams working across multiple AI platforms, Relay offers a practical way to maintain a single source of truth for project context.
