Merlin

I used the free version for a long time and it has only gotten better. I ended up realizing that I need to purchase it because I use it so much. Then I upgraded because I went ham on researching and summarizing things as I'm building websites, doing SEO, creating social posts, responding to people online, writing emails, and summarizing YT videos and articles for research.

I'm in marketing and love apologetics so I'm always researching and summarizing.

I was using WriteSonic and it's usually good, but Merlin is so much easier and many times better at researching and writing.

It's Chrome extension is 100x better than chatsonic (writesonic's chrome extension), same with its YouTube summarizer, and same with it's ability to crawl links like Google Docs and Google Sheets.

I ended up going from tier 1 to tier 3 just 7 days later because I use it so much. Merlin is sooooooo much easier than my other tools and is just as good and many times better.

Edit: And I love their mobile app! ugh it's so convenient.
