## AI agents are the next computing frontier
The desktop launch comes as major tech companies race to dominate consumer-facing AI agents, which many believe will reshape computing, apps, and software-as-a-service businesses.
## Competition is heating up fast
Muse competes with Instinct, which is raising funds at a ten billion dollar valuation, and other AI agents like Poke that exited to Cognition in July.
## Speed is the competitive advantage
Both Muse and Instinct are shipping features rapidly. This week alone, both rolled out voice calling to stay ahead in the race for consumer adoption.
## Key takeaway

AI agents that can take actions on your computer are becoming the next battleground for tech companies competing to replace traditional apps.
