It follows changes across the sources you allow, then prepares the next action.
Example: a supplier email changes a bracket requirement.
Find the changed requirement
Trace affected parts and people
Prepare the handoff for review
Optionally read the open Fusion 360 model's status and parameters
Relay does not edit CAD.
Relay still brings engineering judgment.
Use its cited playbooks and examples without connecting email, files, or CAD.
Example: make a machined bracket easier to manufacture.
Compare manufacturing options: geometry, material, tolerances, process options
Surface relevant DFMA examples
Cite the reasoning behind each suggestion
Pair Fusion 360 only when live model context would help
Choose the AI you already use.
How do you install?
Install Relay in ChatGPT
Connect Relay to ChatGPT in just a few steps.
Open ChatGPTOpen ChatGPT and start a new chat.
Open SettingsClick your profile icon and select Settings.
Enable Developer ModeIn Settings, search for Plugins. Open Plugins, then enable Developer Mode.
Add RelayReturn to the main ChatGPT window. Click Plugins and select Add Plugin.
Connect RelayName: RelayMCP Server URL:Hosted endpoint loading…Authentication: No sign-inSelect the no sign-in option, then confirm the plugin.
Finish adding RelayComplete ChatGPT's connector confirmation. Relay will connect directly without opening a sign-in page.
Verify the connectionAsk: “Can you confirm that Relay is connected and ready to use?”
Set up Fusion 360, if neededAsk: “I use Fusion 360. Give me the Fusion connector setup for ChatGPT.” Relay will provide the correct download and pairing steps.

Choose no sign-inSelect the no sign-in or no authentication option when Claude asks how Relay connects.
Add Relay to ClaudeClick Add to Claude to complete the connection. Relay will connect directly without opening a sign-in page.
Verify the connectionAsk: “Can you confirm that Relay is connected and ready to use?”
Set up Fusion 360, if neededAsk: “I use Fusion 360. Give me the Fusion connector setup for Claude.” Relay will provide the correct download and pairing steps.

What does Fusion support involve?
Add Fusion 360 after Relay is connected
Connect Relay through ChatGPT or Claude first.
Ask Relay for the Fusion setup matching the AI you use.
Download the versioned file Relay returns and verify the SHA-256 checksum shown in the same answer.
Run the connector on the Fusion computer. It installs RelayBridge and shows a short pairing code.
Paste that code into Relay, open Fusion 360, and keep the connector running while you work.
The Fusion companion is optional. The full Relay playbook library, DFMA case records, cross-domain matching, and research seeds work without Fusion. This first Fusion release reads document status and parameters; it does not change CAD.
No Fusion download is exposed on this website.The connected Relay MCP returns the correct ChatGPT or Claude artifact and its checksum.
Use cases for everyday engineering work.

You choose what Relay can use.
01
You choose the sources
Connect selected files, design context, email, or documents. Leave a source disconnected and Relay cannot use it.
02
Your AI processes the answer
With ChatGPT or Claude, the context needed for your question may be processed under that provider's account terms. Private deployments can use an agreed model and hosting environment.
03
You stay in control
Remove a connection in the relevant AI or source system. Manage AI conversation history with that provider. Contact us about data from a 3rd Meridian-managed deployment or enquiry.
For engineering organizations
Connect the work that moves your product forward.
Relay is free for individuals. For teams that need private deployment, selected sources, or a Nexus evaluation, tell us where work gets stuck.
