typingmind extension for exporting chats to a zip file

README.md

TypingMind Extension - Export Chats

Exports chat history from the typingmind application.

Host as Extension

You can host this code as an extension, and configure your typingmind instance to load it on each page load. If you do this, I recommend storing plugin-js-zip.js and the plugin-export-chats.js in separate files. The code will attempt to load plugin-js-zip.js from the same typingmind instance if jszip can't be found on the page.

One-Time Use

If you don't have your own instance, or dont want to host this code yourself, you can run it a single time.

To do so:

1. Open your browser's console on the typing mind page. (cmd+shift+i on mac).
2. Copy all of the code in plugin-js-zip.js and paste it into your typingmind instance's console, press enter
3. Copy all of the code in export-chats.js and paste it into your typingmind instance's console, press enter
4. Close the console

Using the Plugin

1. If the plugin is configured properly, two buttons will appear in the sidebar:
2. export all
3. export current
4. Click either button to initiate a download

Fun fact: The AI designed the export SVG icon that gets inserted into the typingmind app's sidebar.
