No link to a repo? I'm not going to watch a video to know what a project does or how it does it. No thanks.

Thanks.
So it has a new ID for each tunnel/channel/whatever. As usual, that comes with the downside of discoverability: how do you find all your contacts when installing the app? You always need an out of band transfer of the user ID - be it email, username, or a transient one like this.
I'm not sure how much better that is than existing chat apps that don't have discoverability.
Signal has backup 🤔
OOB is arguably better for privacy.
How?
If the OOB is not encrypted --> hello MITM attack or impersonation (unless of course you're physically in the same place, which is quite limiting)
If it's encrypted, why not just keep using encrypted channel? I have to find an encrypted channel to initiate an encrypted chat?
I'm not seeing the benefit
I can give someone my ID in person. I control how it's delivered.
