Artifact, the news app created by Instagram co-founders Kevin Systrom and Mike Krieger, is shutting down just a year after launch. The app used an AI-driven approach to suggest news that users might like to read, but it seems it didn’t catch on with enough people for the Artifact team to continue making the app.

“We have built something that a core group of users love, but we have concluded that the market opportunity isn’t big enough to warrant continued investment in this way,” CEO Kevin Systrom says in a blog post. The app is beginning to wind down today. Users can no longer add new comments or posts, and Artifact will still let you read news “through the end of February.”

Systrom says the team of eight people working on Artifact “will go our separate ways.” He adds that he’s “personally excited to continue building new things” and says that the opportunities for new ideas in the realm of AI “seem limitless.”
