Try GenRealms: Desktop for Mac or Windows. Enter your own API key and define an OpenAI chat endpoint to request from. Download it from this devlog post or the project page.

The default endpoint options are

• gpt-3.5-turbo
• gpt-4
• gpt-3.5-turbo-16k
• gpt-4o

Only chat endpoints will work, but you can use the custom text input to enter whatever you want.

In terms of security, your API key will never be sent to me or saved. The app has no analytics so I don't have any way to know anything you are inputting (even the web version of GenRealms doesn't have analytics).

Please let me know if the Mac build does not work. It was not possible for me to test so it would be a huge help. Also any feedback on the Windows version would be amazing.

Give it a try and let me know what you think! Also let me know if you have any ideas for more features/updates.
