Congrats on the launch Curious how you are handling routing when a message could plausibly belong to two categories, does the AI pick one or surface it in both?
Apache 2.0 + npx simstudio is a good combo - I'd actually try self-hosting this before wiring Slack into another closed agent tool
What's on the roadmap that you're most excited about but can't talk about yet? 👀

Hey Emir! Congrats on the launch. Love open source projects and even more if it's backed by YC. Wish you all the best here

@german_merlo1 thanks so much!
Love that you're supporting multiple integrations instead of reinventing every connector . That should make it much easier to fit into existing tech stacks.

@isaac_warren absolutely.

This is so needed - agents working in isolation just aren't as effective!

@kelly_king3 I completely agree! I hope you enjoy!
