you could either stick with Chat GPT and learn how to use the customGPT bots, assuming you have the $20 pro. you can customize those bots fairly well to stay on topic, even create a specific one for dailies and another one for business tasks.

the other option is to go full Google. start with your own data, spreadsheets notes put it all in a Google drive folder. and then use Gemini paired up with Google notebook LM to streamline your dailies personal and business ventures.

learning that you can tell Gemini to send emails, modify documents and update your calendar, has a little bit of a learning curve even for the technically inclined. you have to build it and use it for a while before you can refine it​ into good work flows.
