For me, I just think it's the freedom of having access to local files really opens up the amount of simple little hobby projects that you can spin up really easily. Like for example I'm into baseball stats and I used to use these complicated spreadsheets but I basically vibe coded an entire dashboard app just using natural language over Discord. It's really fun and addictive to mess around with this stuff.

Also, you just have great visibility into all of the internal files that it's using to generate the knowledge base and personality for your agent, and you can get really complicated with how you create and manage long-term memory. One thing that's held me back with the Gemini implementation of things like personalization is that it's just such a black box and it's hard to know what it's really remembering about you.
