Have you built an AI personal assistant? Tell me about it!

I started vibe coding (is there any other kind anymore?) a personal assistant the other day. Capture natural language voice input, parse it with Gemini as to-do, random thought, schedule request, etc., use Google sheets scripting to populate my calendar and task list, periodically review the data and push out suggestions to my phone. Originally I thought about a Clawdbot, but Gemini convinced me that was overkill. All the published apps I can find have functionality and complex interfaces I don't want to figure out. I don't need an enterprise solution, I just want a second brain.
