Ask HN: Review my startup

Nowadays, people post almost everything happening in and around their life on various social-media platforms. So, I am working on an AI assistant which will return more personalized results by searching for user queries in user's, user's friends', local and global social-media posts.

For example if you want to know whether your friend would be going to that party or not, you can ask this assistant and it will search for his/her social-media posts and will return with relevant results (after taking user's permission) or if you just felt an earthquake you can ask this assistant and it will search for relevant posts in your friends' as well as local social-media posts.

Please let me know your feedback and further suggestions like should I develop a standalone app or should I integrate this with services like Alexa and Google home?
