Absolutely amazing AI, not-so-amazing app or pricing

I use a mac. Do not download the Liner AI app off the App store, just download it off the web. This app store one is based off the ipad and is super buggy, slow, and uncustomizable on macbook. However, if u do get the web download app version, this AI is amazing, with a twist. It is absolutely wonderful to use for research. Is the app very CPU-load heavy? Sure. But there is not a single AI that can beat this in terms of low hallucinations and accurate research. The second catch other than to not dowload the app from the app store is that this AI is expensive. 1000 credits a month for 15$ a month (paid yearly btw) equates to make 5-6 questions on the really advanced research stuff with Liner Scholar or Liner Write. The good thing tho is that Liner sometimes reimburses u credits (500 usually) if the ai agent doesn’t do something correctly or if u test some new features.
