Step 1 — Open Prompt Paul Options

Open the extension menu from Chrome, select Prompt Paul, and open its Options page. The Get Started banner shows whether the selected connection is ready and includes an Open Chat button.

Step 2 — Choose a connection profile

Select an existing profile or create a new connection. Prompt Paul supports an OpenAI-compatible API profile, a Codex subscription (ChatGPT) profile, and a Hermes Agent gateway profile.

Step 3 — Configure the connection type

For an API profile, enter your provider's HTTPS endpoint, API key, and model. Use the model refresh control when available rather than relying on a fixed model name. A saved API key is masked and remains in place when you edit other fields.

For Codex, choose Sign in with ChatGPT; the extension discovers models for the connected subscription. Hermes uses a separate gateway URL and connection flow.

Step 4 — Save the connection

Select Save Settings in the Connection section. Save the Privacy, Web Search, and Page Actions sections separately when you change those capabilities. If you leave with unsaved changes, Prompt Paul warns you before navigating away.

Step 5 — Add optional capabilities

Add a Brave Search API key in Web Search Grounding if you want the Web toggle. Enable Current-Page Actions only when you want the separate Act permission; it is off by default and does not enable arbitrary browser automation.

Step 6 — Open Chat and test

Select Open Chat, then try a selected-text action or load the current page. Use the side-panel status, model capability, and error message to troubleshoot before changing credentials. Keep API keys private and review approvals for any Hermes or Act-enabled run.
