I have been using Sider.ai on my computer for a while now and I can't believe how much it has grown in such a short period of time. There are so many features now that it almost needs organized by category of what they help with (writing, business, etc.) The app is great and if you want a one stop shop for any kind of digital assistance, THIS is the AI you need on your computer/web browser. I am not being paid for this review, I am seriously just so impressed at how much they have to offer.

Charged me a subscription after a year which I'd totally forgotten about, so I figured I might as well try it out. I'm constantly having to switch it back to English because it keeps automatically switching to Korean, making it difficult if not impossible to work with right now.

Damn, this app is very much helpful in every task I do in laptop or computer. This is the GREATEST I have ever seen due to its advance features like: translating,explaining codes, summarizing pages; especially, the sidebar option allowing to access all the apps and help anywhere I need! However, in android, it looks a bit less developed compared to the computing hardware's. But it is a good start. I hope it will reach to its top one day in android version too like in computing devices.
