Live-Typing Chat
Live-typing chat is novel, but Discord and Slack already dominate this crowded category.

Live-typing visibility creates presence that Discord and Slack both lack.
Small communities, casual group chats
Discord · Slack · Telegram
Few months ago I've shared a new kind of markdown editor that we (a team of three from the Czech Republic) have been working on (HN post: https://news.ycombinator.com/item?id=46144801). What resonated with folks the most was Kraa's unique ‘live-typing’ chat feature. We have now acted on this feedback, improved the chat features, and made what we call Kraa Trees.
Trees allow anyone to create a light-weight community / chat channels. It would be a stretch to call it an alternative to Discord, yet, but we hope that the frictionless nature of Trees will make them useful for small groups that want something simpler, more immediate, and less cluttered. With the live-typing being one of the key differentiating features.
You can create your own community/rooms by selecting "Tree of leaves" in the New leaf button dropdown.
You don't need an account to try Kraa nor Kraa Trees. We would love to know what you think!
Live-typing chat is novel, but Discord and Slack already dominate this crowded category.
Keystroke dynamics detect AI posts, but anonymous feeds already exist everywhere.
Anonymous daily civic polls, but self-selected samples and Pol.is already does this.
tRPC but encrypted by default and transport-agnostic.
Clean YouTube frontend, but Invidious and Piped already do ad-free viewing.
Yet another Doodle clone—being free doesn't differentiate in a solved category.
