I like the clean style, I was working on something similar, but never reached that readines-level.

However, the first screen seems a little contra productive. User entered a paragraph and in return gets a "summary" - but it feels so long. It's probably okay... it just triggered me very first impulse.

And what remains unclear is the meaning of "Team Sync". What's happening there? Is it a "group chat" or does it sends messages?

Speaking of... what about integrations with like Teams, Slack, Discord? I know that Teams offers a Meeting Summary which would be great if you could directly store it in _sig_.
