We’re excited to start Cosmik Lab Notes, where we’ll be working in the open and sharing thoughts as we build Semble and the wider Cosmik Network.

⛳ Where we are: Semble Alpha!

Semble is in open alpha now and we’d love for you to try it out! -> semble.so

As observed by one of our early users, alpha is "a bit bare bones...but there are tons of opportunities with this"

[## Missino (@onedeuxtriseigo.nullpo.dev)

I am ecstatic for this. I'm gonna start using this for tracking reading, research, and references for various projects. It's a bit bare bones while it's in alpha but there are tons of opportunities with this. [contains quote post or other embedded content]

Semble is modeled after social knowledge tools like Are.na and Sublime. Right now you can collect links, organize them into collections, and see what others on the network are doing. Check out our other inspirations in this Semble collection:

Products we take design, functionality or organizational inspiration from for semble

To use Semble you currently need a Bluesky account, but in the future we'll provide an independent Cosmik ID.

To get started:

Semble page

Clicking on a card will take you to the Semble page: a page aggregating all of the activity around the link in that card, such as collections it's featured in, and comments about the link. So each link shared on the network will have a corresponding Semble page, which you can also find at https://semble.so/url?id=/<link-url>[1]. So for example, https://semble.so/url?id=https://cosmik.network will aggregate the activity around https://cosmik.network/. In the future we plan for the Semble page to aggregate activity from other ATProto apps and beyond.

🗺 Where we’re headed

We're at early stages but we’re already learning a lot from our alpha community. We have a lot of directions we're eager to explore, including:

… And more to come in future posts! Check out our public roadmap here.

Finally, we’re excited to evolve Semble with you all, so please share thoughts in the comments, leave an issue on Github or Tangled, or reach out!
