Install a Local Test Version

Use a local build only when support provides a test package or you are developing the extension. Normal users should install the Chrome Web Store version.

Before You Start

• Download the local .zip package from the trusted source provided by support.
• Do not share packages from unknown sources; unpacked extensions receive access to ChatGPT and Notion.
• Plan to disable the Chrome Web Store copy while testing so two extension versions do not inject controls into the same ChatGPT page.

1. Extract the Package

Extract the entire ZIP file to a stable folder. Do not load the ZIP itself.

2. Open Chrome Extensions

Enter chrome://extensions/ in Chrome’s address bar.

3. Enable Developer Mode

Turn on Developer mode in the top-right corner. Chrome will show Load unpacked, Pack extension, and Update actions.

4. Load the Extracted Folder

1. Click Load unpacked.
2. Select the extracted folder that directly contains manifest.json.
3. Confirm that the ChatGPT to Notion card appears without errors.
4. Check that its version matches the package you were given. The current source version is 10.0.0; a later test package may show a newer version.

5. Disable the Chrome Web Store Copy

If the store version is installed, turn it off while testing. Keep only one ChatGPT to Notion extension enabled.

Two active copies can produce duplicate buttons, conflicting local storage, or confusing popup results.

6. Refresh ChatGPT

1. Open chatgpt.com.
2. Refresh every open ChatGPT tab.
3. Open a conversation.
4. Open the local extension popup and verify that it connects.

Updating a Local Build

When support sends a replacement package:

1. Extract it to a new folder or replace the previous package files while Chrome is closed.
2. Return to chrome://extensions/.
3. Click the reload icon on the unpacked extension card.
4. Refresh all ChatGPT tabs.

Common Problems

• Manifest file is missing: select the inner folder that directly contains manifest.json.
• Extension card shows an error: click Errors and send the visible message to support.
• Duplicate controls appear in ChatGPT: disable the second extension copy, then refresh ChatGPT.
• Popup cannot connect: refresh the ChatGPT tab after every local extension reload.
• Wrong version is shown: remove the unpacked card and load the correct extracted folder.
