Pretty happy with the experience of using it so far. Asked it to do something to blow me away and it made a podcast about the features it made while onboarding itself to my opensource project called DashClaw.
Then I had it make a marketing video as a test, pretty neat. Obviously all of this was doable but quite impressed with the model underneath since it's all free, for now.

tldr;
private data + untrusted content + outbound capability = hard stop
a markdown file is a wishlist, real security lies within hooks and plugins

honestly this was in June which feels like forever ago and I'm not entirely sure what my plan was haha. I knew I was going to be doing marketing for my projects and thought an editor with LLM capabilities would make it easier, but then I just made a repo and a skill where agents can make marketing material directly

I had a similar idea for an opensource video editor where you edit along side the LLM but I gave up on it haha
