Honestly this app is a good one but of a truth it lags a whole lot. I also find it difficult to copy a written text that I am typing. Another issue with this app is that it doesn't display the full search on your workspace. Liner AI is superb when it comes to academic and scholarly searches but the developers need to fix the lagging issue and the inability to copy a written text or a text while typing.

This app is highly aggravating mainly because the search field keeps deleting my text when I try to enter a question into it. I am not sure what I am doing to cause this to happen. It makes me not want to use it!

I appreciate the AI's responses, but the app has several issues. It occasionally freezes, experiences lag, and has a slow touch response. (My device is mid-range, so I'm unsure how it performs on lower-spec devices.) If these issues are resolved, I will update my review accordingly.
