Smooth

Smooth (smooth.sh) offers an AI browser agent API that autonomously performs web actions such as navigating sites and clicking through interfaces using mouse and keyboard control. The company positions its agent as more reliable, roughly 5x faster, and about 7x cheaper than competing browser agents, achieved by combining small efficient models with carefully curated context design. It targets developers and companies needing to automate web tasks programmatically, with tasks triggered via a single API call, and also ships a token-efficient CLI browser for AI agents. Smooth was founded in 2024 and went through Y Combinator's Fall 2024 (F24) batch.
