I like the idea of using my own AI API key - just to track usage and offload cost if I felt like it. I bought $10 in OpenAI API credit and really have no use for it, would love to put my key on a Kagi page so it could use that to save Kagi a little money.
There are weekends / days I have off and love to spend the entire day using !expert (research) - without blasting away my profitability to Kagi. (Obviously doing this JUST for me would not be in Kagi's best interest) - but I like the idea of putting one's own AI API key in without making it a subscription.
