Not the OP but I just checked my 3 months history and I'm at 800, 469, and 682 searches on DuckDuckGo and 466, 535, and 482 on Google. I feel like I'm a heavy search engine user and I'd have guessed more than this.

I'm considering paying for Kagi but the price seems a bit high, especially considering that I replaced some of my searches with ChatGPT and I pay much less for using the API of OpenAI. But maybe their API price is not sustainable.

For $5 or $10 per month I'd prefer to self-host a search engine and a language model on a server I own.
