Delta Chat
Delta Chat@cross@net.dill.moe do you need an ai summary of your family and private friends or small community groups? Having such summaries for joining pubpic groups with anonymous onboarding is easier to see a potential use in. Anyways, if you have a good example to point to for use of ai in private chatting, we would be happy to hear it. thanks.
Delta ChatWe do not aim for #deltachat to be another social media app. No #ai summaries or suggestions. No public directory of contacts. No discovery via outside identifiers (mobile phone or email). Just you and your contacts privately messaging, in a solid simple user interface on all platforms. End-to-End encryption enforced on two layers. #chatmail relays know and retain nothing, no content or metadata. #webxdc apps allow for custom interactions on top of chats.
Contributors and donations welcome!
Delta ChatSignal and Matrix were founded in popular opposition to the email system but End-to-End encrypted instant messaging via emails works now, and reliably, with #deltachat V2 app releases, and with #chatmail relays forming a growing secure email network that minimizes metadata and enforces TLS and E2EE messaging.
You can't really argue with working code, can you?
Contrary to popular belief SMTP and DKIM and IMAP are no holy ingredients and can be improved upon btw. See eg https://github.com/chatmail/relay/issues/487
Delta ChatV2 #deltachat is rolling out after weeks of internal testing, a major milestone revising how end-to-end encryption works and bringing more beautiful contact and group profiles, direct access to chat-shared apps in the title bar and a "new email" action with setting a subject for those using a classic server.
Best of all, users and developers don't need to co-ordinate anything for upgrading to V2 despite the massive security rework behind the scenes :)

Delta ChatSome people in #Iran successfully use delta with national email providers when outside Internet is cut.
#deltachat designs are #OfflineFirst using delay tolerant protocols. Messages are queued when a path is blocked. email servers are made for this and run at planetary scale.
Messages crossing the border may arrive three days later but they arrive.
Peoples can stay in private touch across time and space, to the extent possible in current breakdown times. Which is what delta is about.
Delta ChatIt had to happen: in-chat multi-player #Quake III Arena #webxdc app, running over @n0iroh@mastodon.social and using the fine work of https://ioquake3.org/ folks. Quake3 app is 1.2MB but you need to download once a game file of ~50 MB. It's only one level.
Realtime-P2P-networked multiplayer gaming arranged through securely end-to-end encrypted email, from a group chat!
Both Quake3's in-game chat as well as game play messages have forward-secrecy. What a weird future, eh? :)
