Antimatter 2.0: It's all about the activities

Jonathan is the Founder & CEO of Antimatter

Antimatter launched at the top of the 2022-23 school year, so it's only appropriate that; at the same time your students are moving on up, Antimatter is too.

Today we're launching a whole bunch of great things:

  • The 2.0 version of our website. We've removed studios and made everything activity-first, and also totally remixable.
  • The beta of our iOS app. For everyone who prefers to create from their phone.
  • The beta for Courses. Courses are a simple, fun way to teach a single idea, led by a meme.

Our new website: Activity-first

The first thing you'll notice when you log in is that your activities are no longer grouped by studio. Activities are just activities: whoever joins that activity is a part of that activity.

The coolest thing that this makes possible is remixing. Found a clever activity run by another teacher on our Discover page? You can immediately launch into setting up the activity yourself with the same parameters.

Similarly, you can also now duplicate your own activities across multiple classrooms.

Also new on the website is our single-player mode creation tools. Over the past year many of you have asked for a simpler way to create a meme for your class, or to share with another teacher. You can now create a meme right from our main page:

We believe this is the simplest and best meme-gen on the web, as we save all of your creations for reuse across web and...iPhone!

Our new iPhone app: The best meme-gen on your iPhone

Because sometimes you only want to use your thumbs.

The new iPhone app is creation focused. Like the website, you can create memes just for fun, or create memes for activities you've created from the website. Of course, your students can do it too, for whenever you're using Antimatter for homework assignments.

You can't create activities yet from the app, but it's coming soon!

Note: This app is still in beta, which means you'll have to download it through Apple's TestFlight app.


Also moving into public beta is our new Courses product. Courses are a simple way to teach a single idea. It happens in three steps:

  1. A meme about the topic
  2. A video explainer for the meme
  3. An activity for people to show what they've learned

You can view Courses listings here.

Finally, we would like to thank all of our teachers who have met with us to give us ideas, and inspiration while creating Antimatter 2.0. As always, we're always available to show you around the platform and get your feedback. Antimatter has been built from the ground up based on feedback from educators like yourself, and that'll never stop.
