hi. looking at Google's Tailwind. it's an AI-powered notebook. add notes, essays, spreadsheets, docs, pdf, etc. and use AI to analyze, summarize, etc. does Microsoft have similar? or plan to offer? how about others?

Microsoft is adding AI to all of Office and to the Edge Browser. No need for a different app, just keep using the ones you've always been using, now with AI. https://blogs.microsoft.com/blog/2023/03/16/introducing-microsoft-365-copilot-your-copilot-for-work/

Dropbox AI is a similar solution. AI for all of your files, emails, etc. https://blog.dropbox.com/topics/product/introducing-AI-powered-tools
