People keep asking us if @jazz.tools will have vector search...
What's better than building a first class vector search feature for Jazz in maybe a couple months?
A single person right now being able to ship it as a small, very neat, very high quality library *on top of* Jazz!

LLMs are a crystallisation not only of human knowledge but also of the human condition
I think there is immense value in them encoding both
- the surprising commonalities in our experiences, struggles and hopes
- *and* the myriad dimensions of individuality

Thinking of Jazz as a DB begs the question: how does it fit into the stack?

Jazz isn’t replacing databases and backends
Jazz isn’t local-first only
Jazz isn’t a sync engine only
Jazz is simply a *new kind* of database

I’ve been using “vibe coding” in a looser sense than Karpathy’s “fully blind” definition, for good reason.
The biggest impact of AI tooling that I’ve seen is senior engineers
a) using their ability to clearly specify what they want and *build* extremely quickly with LLMs

Lots more interesting thoughts on this soon, but as I get deeper into fully auto-running agents, a simple realisation (and I cannot overstate this):
Vibe coding is the first time
computers have felt as magic again
as they have
when they first felt magic to me

Two weeks after alpha-3 which foreshadowed our move to @jazz.tools for greater stability, alpha-4 gets it done!

Special shoutout to @flo-bit.dev who took the lead on this release.
Up next is bridging so Roomy & Discord (later Matrix) folk can share the same space.

Roomy .space (alpha-4)
New domain on roomy.space; backend-switch to Jazz for better performance and access controls; BeeKEM decentralized E2EE explained; notification markers for mentions & unreads.

> The AI just is "one more collaborator" and you just dump the tokens into Jazz state as they come in.
This is the correct mental model
This is the correct mental model
So everything in Jazz is architected around that requirement, from the client to the distributed sync & storage infrastructure.
This is a godsend when you start doing AI stuff. The AI just is "one more collaborator" and you just dump the tokens into Jazz state as they come in.

Streamed LLM responses are the perfect example of why we didn't base @jazz.tools on an existing DB, but are building a new backend + DB from scratch.
Originally we just wanted to support Figma/Notion-like apps where we knew we had to sync 100,000s of tiny edits per second... 🧵

Sync engines are an incremental improvement to the "centralised server + client" model - the minimal possible step towards the real-time nature of apps today.
But we can do much better 🧵

Just built a CRDT-powered real-time demo with ProseKit + @jazz.tools ⚡️
Multiple editors, synced live — no backend needed.

@localfirstconf.com is off to a fantastic start, the number of new people is mind blowing.
For us at @jazz.tools, today was all about getting hands-on and helping people building cool stuff with Jazz - and handing out our first vibe coding certifications!

Just learning about Jazz and I'm beyond excited. I've been wanting to build something similar for a long time. Checking it out now but this looks amazing. Excited to hear more about all the announcements.

Working on some of this at @garden.co has been some of the most exciting & fulfilling work I've ever done. Fantastic software by fantastic people. Looking forward to meeting folks at this year's @localfirstconf.com – the future is now ❤️🎵
Megathread of everything we're announcing for @jazz.tools at @localfirstconf.com
It's been a hell of a year in the best sense and I can't wait to share what we've been cooking.
(And this doesn't even include our "one more thing" 🤫)
Stay tuned as I expand on details over the next couple days!

Nothing better than telling people to edit just their package.json for a 12x perf improvement.
I still think we can do better for this particular hot path internally.
But their app’s “screen of everything” *cold start* is now bottlenecked by React & the DOM!
