Artifact, the buzzy news app from Instagram co-founders Kevin Systrom and Mike Krieger, is shutting down less than a year after its launch. In a note on Medium, Systrom said the app’s “core news reading” features would be online through the end of February, but that it would remove commenting and posting abilities immediately.

Besides its famous founding team, the app was known for AI-centric features as well as Reddit-like commenting and posting abilities. The app had won praise from journalists who appreciated reporter-friendly features like dedicated author pages and had been featured prominently in Apple and Google’s app stores.

But after a year of work, it seems Systrom and Krieger encountered many of the same struggles as founders of buzzy news apps before them. “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,” Systrom wrote.

While he didn’t say what he might do next, Systrom’s note hinted that he may at some point take on a new AI-focused project. “I am personally excited to continue building new things, though only time will tell what that might be,” he wrote. “We live in an exciting time where artificial intelligence is changing just about everything we touch, and the opportunities for new ideas seem limitless.”

In the meantime, Artifact fans have a few more weeks to keep checking headlines before the app goes offline for good.
