About HumanLayer

HumanLayer provides an API and SDK designed to integrate human-in-the-loop capabilities directly into AI agent workflows. It enables AI agents to request human assistance, seek approvals, or escalate tasks through familiar communication channels such as Slack, Discord, Microsoft Teams, SMS, RCS, and email. This makes it particularly useful for developers building orchestration frameworks or tool-calling systems where critical decisions require human oversight, ensuring that autonomous agents can pause and wait for human input when necessary.

The platform is tailored for teams working with LLMs and AI agents who need to maintain control and accountability in automated processes. By offering a straightforward API and SDK, HumanLayer simplifies adding approval workflows and human feedback loops without requiring extensive custom infrastructure. It is especially relevant for business management scenarios where compliance, safety, or nuanced judgment calls demand a human in the loop, bridging the gap between fully autonomous AI and fully manual operations.
