DocsGetting Started

Getting Started

This guide walks you through installing CtxPort and copying your first AI conversation. Even if you’ve never installed a browser extension manually, you’ll be up and running in under 2 minutes.

Requirements

  • Google Chrome version 88 or later (or any Chromium-based browser like Edge, Brave, Arc)
  • A computer running Windows, macOS, or Linux

Install CtxPort

CtxPort is not yet available on the Chrome Web Store. You can install it directly from GitHub.

Step 1: Download

Go to the CtxPort Releases  page on GitHub. Find the latest release and download the file named ctxport-chrome-mv3.zip.

Step 2: Unzip

Locate the downloaded ZIP file on your computer and extract it. You should see a folder containing a manifest.json file — that’s the extension.

Step 3: Open Chrome Extensions

Open Chrome and type chrome://extensions in the address bar, then press Enter.

Step 4: Enable Developer Mode

In the top-right corner of the extensions page, you’ll see a Developer mode toggle. Turn it on.

Step 5: Load the Extension

Click the Load unpacked button that appears in the top-left area. In the file picker, select the folder you extracted in Step 2 (the one containing manifest.json).

Step 6: Done

CtxPort is now installed. You’ll see its icon in your browser’s extension toolbar. If the icon doesn’t appear, click the puzzle piece icon in the toolbar and pin CtxPort.

First Use

  1. Open any supported platform — ChatGPT , Claude , Gemini , or others
  2. Start a new conversation or open an existing one
  3. You’ll see CtxPort’s copy button appear near the conversation
  4. Click the button — or press Alt+Shift+C — to copy the conversation
  5. Open any text editor or note app and paste

You’ll get clean, structured Markdown with a YAML frontmatter header and the full conversation content. See Context Bundle for details on the output format.

Updating CtxPort

When a new version is released:

  1. Download the new ctxport-chrome-mv3.zip from GitHub Releases 
  2. Unzip it to the same location (or a new folder)
  3. Go to chrome://extensions
  4. If you extracted to a new folder, remove the old extension and click Load unpacked again
  5. If you extracted to the same folder, just click the refresh icon on the CtxPort extension card
