Local chat export — Beta

Export your ChatGPT chats — locally and privately.

Your conversations are processed in your browser and saved directly to your Downloads folder. Nimora does not receive your chat content.

No Nimora account
No chat upload
No chat database
No ad network

Three steps. One ZIP.

The beta is installed manually through Chrome Developer Mode. The extension does the export work inside your browser.

Step 01

Download & unzip

Download the beta package and extract the extension folder on your computer.

Step 02

Load unpacked

Open chrome://extensions, enable Developer mode, then choose “Load unpacked”.

Step 03

Open chat & export

Stay logged in to ChatGPT, open the conversation you want, then start the export from the extension.

Privacy by architecture

Your chats stay on your device.

Nimora does not receive, upload, process, or store your conversation content. The website only hosts this landing page and the extension download. Standard web-server access logs may exist at the hosting layer.

FAQ

Does Nimora receive my chat data?

No. This release is designed so the conversation export happens in the browser. Nimora's website does not receive the exported chat content.

Do I need to copy a ChatGPT token or cookie?

No manual token or cookie copying is required. The extension runs in the browser session where you are already signed in.

Does it work without a processing server?

Yes. The website is static, and chat export is performed locally by the browser extension.

Is every attachment guaranteed?

No. This is a beta. Chat text and raw conversation data are the primary supported outputs; some media or attachments can require a retry.

Is this official OpenAI software?

No. Nimora Export is an independent utility and is not affiliated with, endorsed by, or sponsored by OpenAI or ChatGPT.
