Meta’s Muse AI companion surpassed 10 million downloads in the U.S. in the first 40 days. According to TechCrunch AI, the app entered a restricted group of services that achieved this result; Threads is also cited as an example.

The same source reports that Muse retains users better than competing AI apps. Specific retention figures and the full list of comparable services are not provided in the materials.

The significance of the news lies in combining rapid audience attraction with claimed retention; for the AI-companion market, retention is more important than a single download metric. But the conclusions are currently based on a single independent material and its metadata, not on available primary data.
