This looks super interesting as a concept... but has massive issues for me, despite the fact I feel like the product was practically made for the way my mind works... I genuinely want this, or something like this, and how I use Obsidian plugins is to try and work like this but clearly not as slick as a dedicated product... but despite how much I want this, I can't adopt a product that has not just one red flag but three. One red flag might be worth learning about to see if its just that good I can stomach the risk/pride/disgust/etc... but two or even three is just a complete non starter.
My massive red flags:
1st - It currently requires connecting a Google Account. I don't care about the encryption at rest and in transit, thats nice, you've still forced Google in between Me the customer and You the proprietor. My Google Account is my oldest, least wanted account. I've been slowly trying to purge it from my life, but its been growing since the day I got a gMail invite in the closed beta days. It's too personal it has way too much junk leftover from 16+ years of use across dozens of google services.
2nd - They promise that the data will always be exportable, yet I see nothing about formats or methods.
3rd - Its obviously a cloud SaaS ... all the stuff I think and put into something like this, a second brain if you will... should always be accessible. Offline functionality is mandatory
