What are good frameworks or tools for building your own agents — not for posting on Twitter, but for useful knowledge work (eg sorting through email daily)

I've tried a bunch this past year and my favorites are:
- https://kaibanjs.com - best for simple projects
- https://sdk.vercel.ai - best for complex projects
- https://n8n.io - best if you don't want to code

Opinions my own

Hey, I'm a self-taught 27 year developer. I'm doing full-stack by day, and learning to build games by night.
