Prompt Rail for ChatGPT. Last updated October 8, 2026.

Prompt Rail ("the extension") draws a navigation rail on chatgpt.com chats. We do not run servers, we do not use analytics or tracking, and we never sell data.

What the extension reads

On chatgpt.com, the prompts in the chat you have open, to draw the rail and show previews. It reads nothing else.

What the extension sends

Nothing.

What the extension stores

Your bookmarks (the chat's address and title, the message's id and a short preview), in your browser's extension storage on this computer. Removing the extension deletes them.

Chrome Web Store Limited Use

The use of information received will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.

Children

The extension is not directed at children under 13.

Changes

If this policy changes, the new version will be posted on this page with a new date.
