I don't get how of the personal assistant can be useful without having to see my conversational data so this is great.

Do you know if running Whatsapp in Cloud risks your account to be banned?

I'm working on a similar tool, connecting all that data to build your context graph that knows all the people and conversations and expose it via MCP. https://lobu.ai/for/personal/

My approach is requiring you to have a home device where you keep your accounts open in a browser and observing the data from there. The same applies to Linkedin, Instagram, X etc. even reading my timeline to summarize what I need to know without me doomscrolling.
