Dear readers and Semblers,
Sorry we’re late with the April update, but a lot is blooming this spring for Cosmik and Semble! 🌱
Cosmik
We’ve been busy refining our program thesis as part of the Renaissance Philanthropy BiTS accelerator - we’ll have more to share next month.
We gave a talk at the STAMINA working group in the Complex Data Lab at McGill University in Montreal, view the recording here:
ATScience
The ATScience talk recordings are up! View them here
We’re collecting feedback from event participants - if you attended either in-person or via the livestream, please fill out the post-event survey!
Once we process the feedback we’ll share an event writeup
Semble
Connections
Early in April we launched Connections, a new way to organize, curate and discover content on the open social web:
Annotations, bookmarks, and collections are familiar, but connections are a new affordance so we were not sure how the feature would be received by the community. What we have learned is that there are a lot of curious and crafty sensemakers on Semble: people started creating connections the moment we enabled the feature, even before we announced its existence! Overall the response has been great, and we’re excited that the community appreciates them as much as we do.
this is what I am *TALKING* about. I'm sure I'm late but this is such a cool idea from @semble.so. Collections are not new but mapping the specific kind of relationship between two things?? And this is publicly usable shared knowledge? Social knowledge as a service, beautiful.
Or as @joebasser wrote: "Sense is being made"
Connections enable a fun new notification pattern - you get a notification when someone adds a connection to a card in your library, like a dose of microserendipity
AI Agents are also using connections! Here’s @sensemaker.computer providing citations in support of its Bluesky posts:
New knowledge sharing patterns
We’re continuing to notice interesting new knowledge sharing patterns on Semble.
“who’s keeping track of topic X”
“Topic Y is missing a curated collection of resources, let’s create one”
For something so important for applications (arguably moreso than the forward Game Theory problem), I was surprised at how scattered are the resources to learn about it. Feels very jagged. Started a semble collection: semble.so/profile/mpto...! Will add more later. Please consider adding as well!
Open tabs turning into shared trail markers that benefit others
In a weird turn of events I have changed from "make sure this tab stays in my tab list" to "make sure I have a card on @semble.so for this". I'm unsure whether this will actually help with discovery later, but you never know.
Community
We continue to be blown away by the generativity of the atproto community.
@disnetdev wanted an interface for Semble optimized for saving, so he just built one - SembleIt!
My favorite app on the Atmosphere is @semble.so but it doesn't work exactly like I want all the time so I made a client that does less on purpose. Check it out: sembleit.dev www.disnetdev.com/blog/2026-04...
> I wanted a stripped-down Semble. Just my cards, my collections, my connections. No explore, no related surfaces. Nothing pulling at my attention.

> Because Semble is built on atproto, I could just build one. All my cards and collections live on my PDS, not Semble's servers, which means anyone can write another client against the same data.
He also shared a great blog post about his own “Atmospheric Website” which includes a snazzy https://www.disnetdev.com/reading page backed by Semble.
Gov shipped rabbithole.land, a browser extension for collaborative digital trail mapping that interoperates with Semble.
Anuj shipped Disperse, a tool for quickly sharing links to multiple Atmosphere bookmarking/blogging services, including Semble
Introducing Disperse: an experimental sharesheet that allows you to share to several Atmosphere services at once. At launch, it supports @bsky.app, @blackskyweb.xyz, @semble.so, @margin.at, @rabbithole.land, @kipclip.com, and @sill.social, with more planned. 1/
Thanks @Tyler.fun for contributing some great fixes and upgrades to the Semble code!
@uppy-hacker.bsky.social has been sharing some interesting “trending collections” analytics!
Cool analytics on trending @semble.so collections from @uppy-hacker.bsky.social ! Lots of thoughtful curation is happening, and it's exciting to see how new analytics interfaces help show meaningful activity that might otherwise get lost.
What would you like to see next on Semble? We're always keen to hear feedback or suggestions so please be in touch!
Thanks again to all the awesome contributors, and see you in the Atmosphere!
