ChatCache stores a small set of preferences that control how your exports behave. You configure these directly in the popup — there is no settings page to navigate to and no account to sign in to. All preferences are saved locally in your browser using Chrome storage and persist across sessions.

​
Available settings

​
Format selector

Choose your default export format from the dropdown in the popup. The available options are Markdown, HTML, TXT, PDF, JSON, CSV, and PNG. Whichever format you select becomes the default the next time you open the popup, so you do not have to re-select it for every export.

​
Copy to clipboard toggle

Enable this toggle to copy the exported content to your clipboard when you click the export button. Use this when you want to paste the output directly into another application rather than saving a file. You can use the clipboard option independently or alongside a file download depending on your workflow.

​
File name prefix

Set a custom text prefix that gets added to the beginning of every exported file name. This is useful for keeping your downloads folder organized or for distinguishing exports from different projects. For example, a prefix of research- produces file names like research-conversation-title.md.

​
Download location

Exported files are saved to your browser’s default download location. To change where files land, update the download location in your Chrome browser settings.
Use a date-based prefix such as 2026-04- to make your exports sort chronologically in your file system. Combined with a consistent folder, this gives you an automatically ordered archive of your ChatGPT exports over time.

​
How settings are stored

Your preferences are saved locally using Chrome’s built-in storage. No data is sent to any server and no account is required. If you uninstall and reinstall the extension, your saved settings will be cleared along with the extension’s local data.
