Hey! To be honest, I am not sure my feedback would be very valuable. I'm probably your worst type of user -- perma free plan -- simply because I'd only use your tool sporadically. I don't do literature reviews that often, but often enough to think about using a tool like this I suppose.

I totally get it though, it's a difficult thing to balance. If I was doing lit review and deep research daily 6.99 is an amazing deal.
