Wow! I've tried (and failed) to implement a chat application which parries slack and it sounds like the direction you're going in with Chatto is precisely what I was envisioning.

I'll give Chatto a shot, but one of the things I'd love to have is interop with Slack and Discord. Is that on the roadmap or no? I saw that there's a Slack -> Chatto migration tool, but the unfortunate reality is that Slack is used by customers, so even if we internally use Chatto, compatibility with Slack is a must.
