FAQ

Does CtxPort upload my data?

No. CtxPort processes everything locally in your browser. Your conversations never leave your machine. There are no analytics, no telemetry, no servers involved. The source code is open on GitHub  — you can verify this yourself.

Does it support Firefox?

Not yet. Firefox support is planned. Currently CtxPort only works on Chrome and Chromium-based browsers (Edge, Brave, Arc, etc.).

When will it be on the Chrome Web Store?

We’re working on it. For now, you can install CtxPort manually from GitHub Releases . See Getting Started for step-by-step instructions.

Why does CtxPort need host_permissions?

CtxPort needs to read the DOM of AI chat pages to extract conversation content. The host_permissions in the manifest are limited to only the supported platforms (chatgpt.com, claude.ai, etc.) — CtxPort cannot access any other websites.

Can I customize the output format?

CtxPort currently offers four preset formats: Full, User Only, Code Only, and Compact. Custom format templates are a planned feature for a future release.

Does sidebar copy work on all platforms?

Sidebar list copy is currently available on ChatGPT and Claude. Other platforms use different sidebar structures that require separate implementation. See Supported Platforms for the full feature matrix.

Are code block language tags preserved?

Yes. When you use the Code Only format, CtxPort preserves the original language tags from code blocks (e.g., ```python, ```typescript). This means syntax highlighting works correctly when you paste into editors or documentation tools.

Can I copy conversations from the mobile app?

No. CtxPort is a desktop browser extension and only works in Chrome and Chromium-based browsers. Mobile browsers don’t support Chrome extensions.

Is CtxPort free?

Yes. CtxPort is free and open source under the MIT license .
