i built my own version of this called 'threethings' (per pmarca's essay on the subject of personal productivity). i gave an ec2 claude instance access to a folder that is synced with gdrive so it's easy to get local files to the instance, and gsuite access. i had claude build a flutter app one hour when i couldn't sleep, and gave it a telegram bot account. i talk to it via telegram and it keeps tabs on personal and work emails. it does 'deep work' late at night and sends me a 7am summary of my day. my wife is asking for it now, because it will notice urgent emails first thing in the morning and alert me.
i don't have time to open source it, but it's low key revolutionary having a pretty smart AI looking at my life every day and helping me track the three most important things to do.
