I've been spending some time with Gemini Advanced and then compared it to Logos AI. To be upfront, I am a Logos Max subscriber.
Gemini Advanced allows me to "adjust" the summarization. I can tell Gemini to summarize within a certain number of words (for example, summarize in no less than 2000 words) and even make suggestions such as "give me teaching points." It's super helpful for covering a book chapter by chapter.
On the other hand, Logos AI is very brief and offers no adjustments. Is Logos going to address this shortcoming?
