Yesterday I played around with some code, resulting in Schwoogle - schwoogle_dot_com. It’s basically “Bing + ChatGPT”, except it’s not conversation in style, and it’s using DuckDuckGo, and is also 100% open sauce, permissive style.
You can find a link to the code at the primary site. Let me know if you’ve got problems with installing it locally, and I’ll try my best to help.
