Ngrok + Nodarama Bridge Setup

A practical setup guide for connecting ChatGPT Custom GPT actions to your local Nodarama Verbatim bridge during development and testing.

What this is for

Ngrok creates a temporary secure public address for a service running on your own computer.

For Nodarama, that public address lets a Custom GPT send approved bridge requests to your local Verbatim environment while your actual project files stay on your machine.

Why use it

  • Connect hosted ChatGPT reasoning to local project execution.
  • Let Verbatim receive structured actions instead of copy-paste fragments.
  • Keep local file writing controlled by the local app.
  • Support two-way communication for status, results, and correction workflows.

Setup instructions

1

Install ngrok

Download ngrok from ngrok.com, install it, and sign in to your ngrok account.

2

Add your auth token

Copy your ngrok auth token from the ngrok dashboard and add it using the command ngrok provides.

3

Start the Nodarama bridge locally

Launch Nodarama Verbatim and start the local bridge/process that receives Custom GPT requests.

4

Open the tunnel

Run ngrok against the local bridge port. Example format: ngrok http 3000. Use the actual port your bridge is running on.

5

Copy the HTTPS forwarding URL

Ngrok will show a public HTTPS URL. This is the temporary address your Custom GPT action can call.

6

Add the URL to your Custom GPT action

Use the ngrok HTTPS URL as the server/action endpoint for the Nodarama Custom GPT bridge action.

7

Test with a small request

Send a harmless test action first. Confirm Verbatim receives it, displays it, and handles it according to your approval settings.

Official GPT or build your own?

Recommended: use the official Nodarama Custom GPT when available. It gives beginners the cleanest and most consistent setup.

Advanced: create your own Custom GPT using Nodarama’s action schema and bridge rules if you need more control or a private internal setup.

Safety notes

  • Only run ngrok when actively using the bridge.
  • Do not publish your ngrok URL publicly.
  • Do not expose admin endpoints through the tunnel.
  • Use review/tape workflows for changes you do not fully trust.

Final check

The goal is not to let ChatGPT freely write to your computer. The goal is to let ChatGPT communicate with Nodarama Verbatim, while Verbatim remains the controlled local execution layer.

ChatGPT thinks and proposes. Ngrok connects. Nodarama Bridge receives. Verbatim reviews, records, corrects, queues, or executes locally.
